142-538: His scientific career began as a professional astronomer at the Paris Observatory. Vallée co-developed the first computerized map of Mars for NASA in 1963. He later worked on the network information center for the ARPANET , a precursor to the modern Internet , as a staff engineer of SRI International 's Augmentation Research Center (ARC) under Douglas Engelbart . Vallée is also an important figure in

284-468: A capable rival for cars such as the Morris Minor and Volkswagen Beetle ; its sales of more than half a million ensured its production until 1961. After the success of the 4CV, Lefacheux continued to defy the postwar French Ministry of Industrial Production , which had wanted to convert Renault solely to truck manufacture, by directing the development of its successor. He oversaw the prototyping of

426-489: A classical albedo feature it contains. In April 2023, The New York Times reported an updated global map of Mars based on images from the Hope spacecraft . A related, but much more detailed, global Mars map was released by NASA on 16 April 2023. The vast upland region Tharsis contains several massive volcanoes, which include the shield volcano Olympus Mons . The edifice is over 600 km (370 mi) wide. Because

568-617: A close confederate of Puharich; their association would span Vallée's business and paranormal networks until Einhorn was charged with murdering his ex-girlfriend in 1979. More recently, he has been associated with Robert Bigelow as a consultant to the National Institute for Discovery Science and a member of the scientific advisory board of Bigelow Aerospace . In 1979, Robert Emenegger and Alan Sandler updated their 1974 UFOs: Past, Present, and Future documentary with new 1979 footage narrated by Jacques Vallée. The updated version

710-653: A consultant to Stanford applied physicist Peter A. Sturrock 's Institute for Plasma Research. Upon learning that Vallée had written several books about UFOs, Sturrock felt a professional obligation to peruse Vallée's work, prompting his own research in the subject. In 1971, Vallée left Stanford to join the Engelbart group as a senior research engineer. His tenure at ARC coincided with the group's immersion in Erhard Seminars Training and other social experiments, ultimately prompting his departure. While at

852-446: A diameter of 6,779 km (4,212 mi). In terms of orbital motion, a Martian solar day ( sol ) is equal to 24.6 hours, and a Martian solar year is equal to 1.88 Earth years (687 Earth days). Mars has two natural satellites that are small and irregular in shape: Phobos and Deimos . The relatively flat plains in northern parts of Mars strongly contrast with the cratered terrain in southern highlands – this terrain observation

994-412: A distinctive front shape caused by positioning the radiator behind the engine to give a so-called " coal scuttle " bonnet . This continued through the 1920s. Only in 1930 did all models place the radiator at the front. The bonnet badge changed from circular to the familiar and continuing diamond shape in 1925. The practice of installing the radiator behind the engine against the firewall continued during

1136-634: A foreign nameplate to win the award. (In 2000, Motor Trend did away with separate awards for domestic and imported vehicles.) A surprising side effect of the AMC linkup was that Renault felt the effects of the Arab League boycott of companies doing business with Israel, as AMC built Jeeps there under license. Plans to sell the Renault 9 in the Middle East were mothballed as a result. Introductions in

1278-422: A global magnetic field, the types and distribution of auroras there differ from those on Earth; rather than being mostly restricted to polar regions as is the case on Earth, a Martian aurora can encompass the planet. In September 2017, NASA reported radiation levels on the surface of the planet Mars were temporarily doubled , and were associated with an aurora 25 times brighter than any observed earlier, due to

1420-488: A high ratio of deuterium in Gale Crater , though not significantly high enough to suggest the former presence of an ocean. Other scientists caution that these results have not been confirmed, and point out that Martian climate models have not yet shown that the planet was warm enough in the past to support bodies of liquid water. Near the northern polar cap is the 81.4 kilometres (50.6 mi) wide Korolev Crater , which

1562-653: A joint AMC/Renault project since some early sketches of the XJ series were made in collaboration by Renault and AMC engineers (AMC insisted that the XJ Cherokee was designed by AMC personnel; even though a former Renault engineer designed the Quadra-Link front suspension for the XJ series). The Jeep also used wheels and seats from Renault. Part of AMC's overall strategy was to save manufacturing costs by using Renault's parts and engineering expertise when practical. This led to

1704-490: A low of 30  Pa (0.0044  psi ) on Olympus Mons to over 1,155 Pa (0.1675 psi) in Hellas Planitia , with a mean pressure at the surface level of 600 Pa (0.087 psi). The highest atmospheric density on Mars is equal to that found 35 kilometres (22 mi) above Earth's surface. The resulting mean surface pressure is only 0.6% of Earth's 101.3 kPa (14.69 psi). The scale height of

1846-442: A massive, and unexpected, solar storm in the middle of the month. Mars has seasons, alternating between its northern and southern hemispheres, similar to on Earth. Additionally the orbit of Mars has, compared to Earth's, a large eccentricity and approaches perihelion when it is summer in its southern hemisphere and winter in its northern, and aphelion when it is winter in its southern hemisphere and summer in its northern. As

1988-542: A minimum thickness of 6 kilometres (3.7 mi) in Isidis Planitia , and a maximum thickness of 117 kilometres (73 mi) in the southern Tharsis plateau. For comparison, Earth's crust averages 27.3 ± 4.8 km in thickness. The most abundant elements in the Martian crust are silicon , oxygen , iron , magnesium , aluminium , calcium , and potassium . Mars is confirmed to be seismically active; in 2019 it

2130-473: A record of erosion caused by the catastrophic release of water from subsurface aquifers, though some of these structures have been hypothesized to result from the action of glaciers or lava. One of the larger examples, Ma'adim Vallis , is 700 kilometres (430 mi) long, much greater than the Grand Canyon, with a width of 20 kilometres (12 mi) and a depth of 2 kilometres (1.2 mi) in places. It

2272-547: A record of impacts from that era, whereas much of the remaining surface is probably underlain by immense impact basins caused by those events. However, more recent modeling has disputed the existence of the Late Heavy Bombardment. There is evidence of an enormous impact basin in the Northern Hemisphere of Mars, spanning 10,600 by 8,500 kilometres (6,600 by 5,300 mi), or roughly four times

2414-460: A result, the seasons in its southern hemisphere are more extreme and the seasons in its northern are milder than would otherwise be the case. The summer temperatures in the south can be warmer than the equivalent summer temperatures in the north by up to 30 °C (54 °F). Martian surface temperatures vary from lows of about −110 °C (−166 °F) to highs of up to 35 °C (95 °F) in equatorial summer. The wide range in temperatures

2556-471: A small crater (later called Airy-0 ), located in the Sinus Meridiani ("Middle Bay" or "Meridian Bay"), was chosen by Merton E. Davies , Harold Masursky , and Gérard de Vaucouleurs for the definition of 0.0° longitude to coincide with the original selection. Because Mars has no oceans, and hence no " sea level ", a zero-elevation surface had to be selected as a reference level; this is called

2698-486: A small star fitted above the front hood logo. This proved to be a winning differentiator and in the 1930s all cars changed to the Stella suffix from the previous two alpha character model identifiers. The Grand Renaults were built using a considerable amount of aluminium . Engines, brakes, transmissions, floor and running boards and all external body panels were aluminium. Of the few that were built, many went to scrap to aid

2840-535: A storm over a small area, to gigantic storms that cover the entire planet. They tend to occur when Mars is closest to the Sun, and have been shown to increase global temperature. Seasons also produce dry ice covering polar ice caps . Large areas of the polar regions of Mars While Mars contains water in larger amounts , most of it is dust covered water ice at the Martian polar ice caps . The volume of water ice in

2982-635: A temporary security clearance for him in 1974), Vallée was intermittently consulted on classified remote viewing research (including the Stargate Project ) throughout the 1970s and 1980s. During the early SRI experiments (led by Puthoff and Russell Targ in conjunction with Green as CIA contract monitor), he became acquainted with Uri Geller , Edgar Mitchell , Charles Musès , Andrija Puharich , Jack Sarfatti , Arthur M. Young , Edwin C. May , Pat Price and Ingo Swann . In 1973, Doubleday editor Bill Whitehead introduced Vallée to Ira Einhorn ,

3124-491: A very thick lithosphere compared to Earth. Below this the mantle gradually becomes more ductile, and the seismic wave velocity starts to grow again. The Martian mantle does not appear to have a thermally insulating layer analogous to Earth's lower mantle ; instead, below 1050 km in depth, it becomes mineralogically similar to Earth's transition zone . At the bottom of the mantle lies a basal liquid silicate layer approximately 150–180 km thick. Mars's iron and nickel core

3266-482: A visitation by some advanced race of space travellers (the extraterrestrial hypothesis or "ETH"). It is the view of the author that research on UFOs need not be restricted to these two alternatives. On the contrary, the accumulated data base exhibits several patterns tending to indicate that UFOs are real, represent a previously unrecognized phenomenon, and that the facts do not support the common concept of "space visitors". Five specific arguments articulated here contradict

3408-747: A year later, on 4 April, this time delivered by the Americans, and on 3 and 15 September 1943. A few weeks after the Liberation of Paris , at the start of September 1944, the factory gates at Renault's Billancourt plant reopened. Operations restarted slowly, in an atmosphere poisoned by plotting and political conspiracy. In 1936, the Billancourt factory had been the scene of violent political and industrial unrest that had surfaced under Léon Blum 's Popular Front government. The political jostling and violence that followed liberation ostensibly reflected

3550-452: Is Syrtis Major Planum . The permanent northern polar ice cap is named Planum Boreum . The southern cap is called Planum Australe . Mars's equator is defined by its rotation, but the location of its Prime Meridian was specified, as was Earth's (at Greenwich ), by choice of an arbitrary point; Mädler and Beer selected a line for their first maps of Mars in 1830. After the spacecraft Mariner 9 provided extensive imagery of Mars in 1972,

3692-527: Is a French multinational automobile manufacturer established in 1899. The company currently produces a range of cars and vans. It has manufactured trucks , tractors , tanks , buses /coaches, aircraft and aircraft engines, as well as autorail vehicles. Headquartered in Boulogne-Billancourt , near Paris , the Renault group is made up of the namesake Renault marque along with subsidiaries Alpine , Dacia from Romania and Mobilize . It

3834-406: Is a light albedo feature clearly visible from Earth. There are other notable impact features, such as Argyre , which is around 1,800 kilometres (1,100 mi) in diameter, and Isidis , which is around 1,500 kilometres (930 mi) in diameter. Due to the smaller mass and size of Mars, the probability of an object colliding with the planet is about half that of Earth. Mars is located closer to

3976-432: Is approximately half the diameter of Earth, with a surface area only slightly less than the total area of Earth's dry land. Mars is less dense than Earth, having about 15% of Earth's volume and 11% of Earth's mass , resulting in about 38% of Earth's surface gravity . Mars is the only presently known example of a desert planet , a rocky planet with a surface akin to that of Earth's hot deserts . The red-orange appearance of

4118-766: Is completely molten, with no solid inner core. It is around half of Mars's radius, approximately 1650–1675 km, and is enriched in light elements such as sulfur , oxygen, carbon , and hydrogen . Mars is a terrestrial planet with a surface that consists of minerals containing silicon and oxygen, metals , and other elements that typically make up rock . The Martian surface is primarily composed of tholeiitic basalt , although parts are more silica -rich than typical basalt and may be similar to andesitic rocks on Earth, or silica glass. Regions of low albedo suggest concentrations of plagioclase feldspar , with northern low albedo regions displaying higher than normal concentrations of sheet silicates and high-silicon glass. Parts of

4260-429: Is divided into two kinds of areas, with differing albedo. The paler plains covered with dust and sand rich in reddish iron oxides were once thought of as Martian "continents" and given names like Arabia Terra ( land of Arabia ) or Amazonis Planitia ( Amazonian plain ). The dark features were thought to be seas, hence their names Mare Erythraeum , Mare Sirenum and Aurorae Sinus . The largest dark feature seen from Earth

4402-487: Is due to the thin atmosphere which cannot store much solar heat, the low atmospheric pressure (about 1% that of the atmosphere of Earth ), and the low thermal inertia of Martian soil. The planet is 1.52 times as far from the Sun as Earth, resulting in just 43% of the amount of sunlight. Mars has the largest dust storms in the Solar System, reaching speeds of over 160 km/h (100 mph). These can vary from

4544-560: Is entitled UFOs: It Has Begun . Vallée served as the real-life model for Lacombe, the researcher portrayed by François Truffaut in Steven Spielberg 's Close Encounters of the Third Kind . He also attempted to interest Spielberg in an alternative explanation for the phenomenon. In an interview on Conspire.com, Vallée said, "I argued with him that the subject was even more interesting if it wasn't extraterrestrials. If it

4686-437: Is known as the Martian dichotomy . Mars hosts many enormous extinct volcanoes (the tallest is Olympus Mons , 21.9 km or 13.6 mi tall) and one of the largest canyons in the Solar System ( Valles Marineris , 4,000 km or 2,500 mi long). Geologically , the planet is fairly active with marsquakes trembling underneath the ground, dust devils sweeping across the landscape, and cirrus clouds . Carbon dioxide

4828-643: Is known for its role in motor sport , particularly rallying , Formula 1 and Formula E . Its early work on mathematical curve modeling for car bodies is significant in the history of computer graphics . The Renault corporation was founded on 25 February 1899 as Société Renault Frères by Louis Renault and his brothers Marcel and Fernand . Louis was a bright, aspiring young engineer who had already designed and built several prototypes before teaming up with his brothers, who had honed their business skills working for their father's textile firm. While Louis handled design and production, Marcel and Fernand managed

4970-816: Is part of Renault–Nissan–Mitsubishi Alliance (previously Renault–Nissan Alliance) since 1999. The French state and Nissan each own a 15% share of the company. Renault also has other subsidiaries such as RCI Banque (automotive financing), Renault Retail Group (automotive distribution), and Motrio (automotive parts). Renault has various joint ventures, including Horse Powertrain (engine development), Oyak-Renault (Turkish manufacturing), Renault Nissan Automotive India (Indian manufacturing), and Renault Korea (previously Renault Samsung Motors, South Korean manufacturing). Renault Trucks , previously known as Renault Véhicules Industriels, has been part of Volvo since 2001. Renault Agriculture became 100% owned by German agricultural equipment manufacturer CLAAS in 2008. Renault

5112-448: Is striking: northern plains flattened by lava flows contrast with the southern highlands, pitted and cratered by ancient impacts. It is possible that, four billion years ago, the Northern Hemisphere of Mars was struck by an object one-tenth to two-thirds the size of Earth's Moon . If this is the case, the Northern Hemisphere of Mars would be the site of an impact crater 10,600 by 8,500 kilometres (6,600 by 5,300 mi) in size, or roughly

5254-541: Is substantially present in Mars's polar ice caps and thin atmosphere . During a year, there are large surface temperature swings on the surface between −78.5 °C (−109.3 °F) to 5.7 °C (42.3 °F) similar to Earth's seasons , as both planets have significant axial tilt . Mars was formed approximately 4.5 billion years ago. During the Noachian period (4.5 to 3.5 billion years ago), Mars's surface

5396-643: Is the fourth planet from the Sun . The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname " the Red Planet ". Mars is among the brightest objects in Earth's sky , and its high-contrast albedo features have made it a common subject for telescope viewing. It is classified as a terrestrial planet and is the second smallest of the Solar System 's planets with

5538-606: Is thought to have been carved by flowing water early in Mars's history. The youngest of these channels is thought to have formed only a few million years ago. Elsewhere, particularly on the oldest areas of the Martian surface, finer-scale, dendritic networks of valleys are spread across significant proportions of the landscape. Features of these valleys and their distribution strongly imply that they were carved by runoff resulting from precipitation in early Mars history. Subsurface water flow and groundwater sapping may play important subsidiary roles in some networks, but precipitation

5680-550: The areoid of Mars, analogous to the terrestrial geoid . Zero altitude was defined by the height at which there is 610.5  Pa (6.105  mbar ) of atmospheric pressure. This pressure corresponds to the triple point of water, and it is about 0.6% of the sea level surface pressure on Earth (0.006 atm). For mapping purposes, the United States Geological Survey divides the surface of Mars into thirty cartographic quadrangles , each named for

5822-685: The Chevrolet Corvair . Renault also sold the Renault Caravelle roadster, which was called the Floride outside North America. During the 1950s, Renault absorbed two small French heavy vehicle manufacturers ( Somua and Latil ) and in 1955 merged them with its own truck and bus division to form the Société Anonyme de Véhicules Industriels et d'Equipements Mécaniques (Saviem). Renault then launched two successful cars –

The Dauphine sold well as the company expanded production and sales further abroad, including Africa and North America. The Dauphine sold well initially in the US, although it subsequently became outdated against increased competition, including from the country's nascent domestic compacts such as

6106-505: The French Space Committee , Vallée claims to have witnessed the destruction of the tracking tapes of an unknown object orbiting the Earth. The particular object was a retrograde satellite – that is, a satellite orbiting the Earth in the opposite direction to the Earth's rotation. At the time he observed this, there were no rockets powerful enough to launch such a satellite, so the team was quite excited as they assumed that

6248-593: The Grand Palais in Paris . During World War I, the company branched out into ammunition and military vehicles such as the revolutionary Renault FT tank . Production of aero engines also ramped up with additional licensed production of the firms' products being undertaken by various companies, including Rolls-Royce who got their start in the aircraft engine business producing a batch of Renault 70 hp air-cooled V8s. Renault's most successful aircraft engine

6674-598: The R 35 . During the late 1920s and early 1930s, Renault was surpassed by Citroën as the largest car manufacturer in France. Citroën models at the time were more innovative and popular than Renault's. However, by mid-1930s the French manufacturers were hit by the Great Depression . Renault could initially offset losses through its tractor, railroad and weaponry businesses, while Citroën filed for bankruptcy , and

6816-516: The Renault 4 (1961–1992), a practical competitor for the likes of the Citroën 2CV , and the rear-engined Renault 8 . The larger Renault 10 followed the success of the Renault 8, and was the last rear-engined Renault. The company achieved success with the more modern and more upmarket Renault 16 , a pioneering hatchback launched in 1966, followed by the smaller Renault 6 . On 16 January 1970,

6958-469: The Renault 6 and Renault 16 . The model was a success. 1970 was also the first year during which Renault produced more than a million cars in a single year, building 1,055,803. The company's compact and economical Renault 5 model, launched in January 1972, was another success, anticipating the 1973 energy crisis . The Renault 18 was introduced in 1978 and the larger Renault 20 in 1975. During

In 1963, Vallée relocated to Chicago, Illinois . He was initially employed as a systems analyst at nearby Northwestern University while continuing to pursue non-institutional ufological research with his mentor, J. Allen Hynek , the chair of

7242-584: The XJ Cherokee , could be launched. When the bottom fell out of the four-wheel drive (4×4) truck market in early 1980, AMC was in danger of bankruptcy. To protect its investment, Renault bailed AMC out with cash – at the price of a controlling 47.5% interest. Renault replaced some AMC executives, and Jose Dedeurwaerder of Renault became President of AMC. The partnership resulted in the marketing of Jeep vehicles in Europe. The Jeep XJ Cherokee may have been

In September 2015, NASA announced that they had found strong evidence of hydrated brine flows in recurring slope lineae , based on spectrometer readings of the darkened areas of slopes. These streaks flow downhill in Martian summer, when the temperature is above −23 °C, and freeze at lower temperatures. These observations supported earlier hypotheses, based on timing of formation and their rate of growth, that these dark streaks resulted from water flowing just below

Other companies financed by Vallée (most notably HandyLab, which produced an instrument recognized as being "transformative for oncology ") were successfully acquired by Becton-Dickinson , Intel , Lucent , AOL , Cisco , Wilson Greatbatch and Intuitive Surgical . He has also served on

7952-928: The "Rambler Renault" was positioned as an alternative to the Mercedes-Benz "Fintail" cars. Later, Renault continued to make and sell a hybrid of AMC's Rambler American and Rambler Classic called the Renault Torino in Argentina (sold through IKA-Renault). Renault partnered with AMC on other projects, such as a rotary concept engine in the late 1960s. In the late 1960s and 1970s, the company established subsidiaries in Eastern Europe , most notably Dacia in Romania, and South America (many of which remain active) and forged technological cooperation agreements with Volvo and Peugeot , (for instance, for

8094-522: The 1930s had the suffix "Quatre" and the luxury six-cylinder models that were sold with the suffix "-six", later becoming "Stella." For example, in 1928, when Renault produced 45,809 cars, its seven models started with a 6CV, a 10CV, the Monasix , 15CV, the Vivasix , the 18/22CV and the 40CV . Renault offered eight body styles. The longer rolling chassis were available to coachbuilders . The smaller were

Renault Caudron airplanes settled several speed world records during the 1930s. Renault continued developing tanks as part of France's rearming effort, including the D1 and the FT's replacement,

8378-427: The 1936–1938 strikes had left him without political allies and no one came to his aid. He was incarcerated at Fresnes prison where he died on 24 October 1944 under unclear circumstances, while awaiting trial. On 1 January 1945, by de Gaulle's decree, the company was posthumously expropriated from Louis Renault. On 16 January 1945, it was formally nationalised as Régie Nationale des Usines Renault . Renault's were

Renault introduced new models at the Paris Motor Show , which was held in September or October of the year. This led to confusion about model years. For example, a "1927" model was mostly produced in 1928. Renault cars during this time period had two model lines; the economy four-cylinder engine models that in

8662-514: The British Royal Air Force (RAF) launched 235 low-level bombers at the Île Seguin, Billancourt, Paris plant, the largest number aimed at a single target during the war. 460 metric tons (450 long tons; 510 short tons) of bombs were dropped on the plant and the surrounding area, causing extensive damage along with heavy civilian casualties. Renault resolved to rebuild the factory as quickly as possible, but bombardments continued

8804-737: The ETH: Vallée's ideas about Miracle at Fatima and Marian apparitions are that they are a class of UFO encounters. Vallée is one of the first people to speculate publicly about the possibility that the " solar dance " at Fatima was a UFO. Vallée has also speculated that UFO activity may have caused other religious apparitions, including Our Lady of Lourdes and the revelations of Joseph Smith . Vallée believes that religious experiences such as these should be studied outside of their religious contexts. Via professional association with SRI and independent friendships with Harold E. Puthoff and Central Intelligence Agency analyst Kit Green (who obtained

These events contributed to Vallée's lifelong interest in the UFO phenomenon. Vallée began to correspond with Aimé Michel (who would become a key mentor and research collaborator) in 1958. In the mid-1960s, like many other UFO researchers, Vallée initially attempted to validate

9088-575: The French automobile industry. The disputes were eventually quashed by Renault in a particularly intransigent way, and over 2,000 people lost their jobs. After the French capitulation in 1940 , Louis Renault refused to produce tanks for Nazi Germany , which took control of his factories. As Renault was manufacturing the Renault UE tank for the Allies, he produced trucks instead. On 3 March 1942,

By 1907, a significant percentage of London and Paris taxis had been built by Renault. Renault was also the best-selling foreign brand in New York in 1907 and 1908. In 1908 the company produced 3,575 units, becoming the country's largest car manufacturer. The brothers recognised

9372-592: The LCVs were the 4, 5, and 12 Société and the Estafette. The company added 54,086 buses/coaches and trucks. In North America, Renault partnered with American Motors Corporation (AMC), lending AMC operating capital and buying a minority 22.5% stake in the company in late 1979. The first Renault model sold through AMC's dealerships was the R5, renamed Renault Le Car. Jeep was keeping AMC afloat until new products, particularly

9514-478: The Martian ionosphere , lowering the atmospheric density by stripping away atoms from the outer layer. Both Mars Global Surveyor and Mars Express have detected ionized atmospheric particles trailing off into space behind Mars, and this atmospheric loss is being studied by the MAVEN orbiter. Compared to Earth, the atmosphere of Mars is quite rarefied. Atmospheric pressure on the surface today ranges from

9656-538: The Martian sky a tawny color when seen from the surface. It may take on a pink hue due to iron oxide particles suspended in it. The concentration of methane in the Martian atmosphere fluctuates from about 0.24 ppb during the northern winter to about 0.65 ppb during the summer. Estimates of its lifetime range from 0.6 to 4 years, so its presence indicates that an active source of the gas must be present. Methane could be produced by non-biological process such as serpentinization involving water, carbon dioxide, and

9798-415: The Martian surface is caused by ferric oxide , or rust . It can look like butterscotch ; other common surface colors include golden, brown, tan, and greenish, depending on the minerals present. Like Earth, Mars is differentiated into a dense metallic core overlaid by less dense rocky layers. The outermost layer is the crust, which is on average about 42–56 kilometres (26–35 mi) thick, with

9940-420: The Martian surface. Mars is an attractive target for future human exploration missions , though in the 2020s no such mission is planned. Scientists have theorized that during the Solar System's formation , Mars was created as the result of a random process of run-away accretion of material from the protoplanetary disk that orbited the Sun. Mars has many distinctive chemical features caused by its position in

10082-593: The Moon, Johann Heinrich von Mädler and Wilhelm Beer were the first areographers. They began by establishing that most of Mars's surface features were permanent and by more precisely determining the planet's rotation period. In 1840, Mädler combined ten years of observations and drew the first map of Mars. Features on Mars are named from a variety of sources. Albedo features are named for classical mythology. Craters larger than roughly 50 km are named for deceased scientists and writers and others who have contributed to

10224-595: The National Advisory Committee of the University of Michigan College of Engineering and authored four books on high technology, including Computer Message Systems , Electronic Meetings , The Network Revolution , and The Heart of the Internet . According to Vallée, he sighted an unidentified flying object over his Pontoise home in May 1955. Six years later in 1961, while working on the staff of

10366-412: The Solar System. Elements with comparatively low boiling points, such as chlorine , phosphorus , and sulfur , are much more common on Mars than on Earth; these elements were probably pushed outward by the young Sun's energetic solar wind . After the formation of the planets, the inner Solar System may have been subjected to the so-called Late Heavy Bombardment . About 60% of the surface of Mars shows

10508-623: The Type GP was produced between 1919 and 1930. It was based on the FT tank. Renault struggled to compete with the increasingly popular small, affordable "people's cars," while problems with the United States stock market and the workforce slowed the company's growth. Renault also had to find a way to distribute its vehicles more efficiently. In 1920, Louis signed one of its first distribution contracts with Gustave Gueudet , an entrepreneur from Amiens , France. The pre-First World War cars had

10650-504: The US by 1928 had declined to near-zero from their high point prior to WWI. A Type NM 40CV Tourer had a US list price of over US$ 4,600 ($ 81,623 in 2023 dollars ), about the same as a Cadillac V-12 , Packard Eight , Fiat 520 , or Delahaye . Closed 7-seat limousines like the Renault Suprastella started at US$ 6,000 ($ 106,465 in 2023 dollars ). Cars were conservatively engineered and built. The Renault Vivasix , model PG1,

10792-710: The US during the 1980s included the Renault Alliance GTA and GTA convertible – an automatic-top convertible with a 2.0 L engine – big for a car of its class and the Renault Fuego coupé. The Alliance was followed by the Encore (US version of the Renault 11 ), an Alliance-based hatchback. In 1982, Renault become the second European automaker to build cars in the US, after Volkswagen . However, bland styling and poor product quality proved insurmountable. Eventually, Renault sold AMC to Chrysler in 1987 after

10934-762: The University's astronomy department. Professionally, he began to conduct early artificial intelligence research and received a PhD in industrial engineering and computer science from the institution in 1967. Thereafter, he briefly worked for Royal Dutch Shell (in Paris ) and the RCA Service Company (in Cherry Hill, New Jersey ) as an engineer before joining the Stanford University Computer Center as manager of information systems in 1969. In 1970, Vallée became

11076-462: The area of Europe, Asia, and Australia combined, surpassing Utopia Planitia and the Moon's South Pole–Aitken basin as the largest impact crater in the Solar System. Mars is scarred by a number of impact craters: a total of 43,000 observed craters with a diameter of 5 kilometres (3.1 mi) or greater have been found. The largest exposed crater is Hellas , which is 2,300 kilometres (1,400 mi) wide and 7,000 metres (23,000 ft) deep, and

11218-716: The assassination of Renault's chairman, Georges Besse by Action directe . The Renault Medallion (Renault 21 in Europe) sedan and wagon was sold from 1987 until 1989 through Jeep-Eagle dealerships. Jeep-Eagle was the division Chrysler created out of the former AMC. Renault imports ended after 1989. A completely new full-sized 4-door sedan, the Eagle Premier , was developed during the partnership between AMC and Renault. The Premier design, as well as its state-of-the-art manufacturing facility in Bramalea, Ontario , Canada, were

11360-419: The atmosphere is about 10.8 kilometres (6.7 mi), which is higher than Earth's 6 kilometres (3.7 mi), because the surface gravity of Mars is only about 38% of Earth's. The atmosphere of Mars consists of about 96% carbon dioxide , 1.93% argon and 1.89% nitrogen along with traces of oxygen and water. The atmosphere is quite dusty, containing particulates about 1.5 μm in diameter which give

11502-406: The atmosphere is small, but enough to produce larger clouds of water ice and different cases of snow and frost , often mixed with snow of carbon dioxide dry ice . Landforms visible on Mars strongly suggest that liquid water has existed on the planet's surface. Huge linear swathes of scoured ground, known as outflow channels , cut across the surface in about 25 places. These are thought to be

11644-467: The broken fragments of "Tintina" rock and "Sutton Inlier" rock as well as in veins and nodules in other rocks like "Knorr" rock and "Wernicke" rock . Analysis using the rover's DAN instrument provided evidence of subsurface water, amounting to as much as 4% water content, down to a depth of 60 centimetres (24 in), during the rover's traverse from the Bradbury Landing site to

11786-508: The business. The first Renault car, the Renault Voiturette 1CV, was sold to a friend of Louis' father after giving him a test ride on 24 December 1898. In 1903, Renault began to manufacture its own engines; until then it had purchased them from De Dion-Bouton . The first major volume sale came in 1905 when Société des Automobiles de Place bought Renault AG1 cars to establish a fleet of taxis. These vehicles were later used by

11928-507: The co-founder of the family of three Euro-America Ventures funds in North America and Europe. As a private investor, he continues to serve as executive manager of Documatica Financial, a San Francisco boutique focused on early-stage healthcare and technology startups. Among the companies for which he spearheaded early-stage financings, fourteen achieved initial public offerings , including Electronics for Imaging , Accuray (developers of

12070-420: The company into four business areas: automobiles (for car and light commercial vehicles or LCVs), finance and services, commercial vehicles (coaches and trucks over 2.5 tons GVW ), and minor operations under an industrial enterprises division (farm machinery, plastics, foundry, etc.). In 1980, Renault produced 2,053,677 cars and LCVs. The cars at the time were the Renault 4, 5, 6, 7, 12, 14, 16, 18, 20, and 30;

12212-685: The design was inherited by the Chrysler Corporation in late 1987 after Renault divested AMC – which debuted in 1989 as the Jeep Concept 1 (evolving into the Jeep Grand Cherokee in April 1992). The Renault-AMC marketing effort in passenger cars was unsuccessful compared to the popularity of Jeep vehicles. This was because, by the time the Renault range was ready, the second energy crisis was over, taking with it much of

12354-529: The desire for economical, compact cars. One exception was the Renault Alliance (an Americanised version of the Renault 9 ), which debuted for the 1983 model year. Assembled at AMC's Kenosha, Wisconsin plant, the Alliance received Motor Trend ' s domestic Car of The Year award in 1983. The Alliance's 72% US content allowed it to qualify as a domestic vehicle, making it the first car with

12496-692: The development of the PRV V6 engine, which was used in Renault 30 , Peugeot 604 , and Volvo 260 in the late 1970s). In the mid-1960s, Renault Australia was set up in Melbourne. The company produced and assembled models including the R8, R10, R12, R16, sporty R15, R17 coupes, R18, and R20. The unit closed in 1981 and the factory closed with LNC Industries taking over import and distribution of Renaults in Australia. When Peugeot acquired Citroën and formed PSA ,

12638-458: The edges of boulders and other obstacles in their path. The commonly accepted hypotheses include that they are dark underlying layers of soil revealed after avalanches of bright dust or dust devils . Several other explanations have been put forward, including those that involve water or even the growth of organisms. Environmental radiation levels on the surface are on average 0.64 millisieverts of radiation per day, and significantly less than

12780-632: The end of the decade. Renault acquired a controlling stake in Automobiles Alpine in 1973, and over the decades, Renault developed a collaborative partnership with Nash Motors Rambler and its successor American Motors Corporation (AMC). From 1962 until 1967, Renault assembled complete knock down (CKD) kits of the Rambler Classic sedans in its factory in Belgium. Renault did not have large or luxury cars in its product line and

12922-599: The equivalent of an MS in astrophysics from the University of Lille Nord de France in 1961. He began his professional life as an astronomer at the Paris Observatory in 1961. He was awarded the Jules Verne Prize for his first science fiction novel, Le Sub-espace (1961), published under the pseudonym of Jérôme Sériel. Vallée moved to the United States in 1962 and began working as a research associate in astronomy under Gérard de Vaucouleurs at

13064-500: The extraterrestrial visitation hypothesis, Vallée has suggested a multidimensional visitation hypothesis . This hypothesis represents an extension of the ETH where the alleged extraterrestrials could be potentially from anywhere. The entities could be multidimensional beyond space-time; thus they could coexist with humans, yet remain undetected. Vallée's opposition to the popular ETH was not well received by prominent U.S. ufologists, hence he

13206-489: The firm formed several international spinoffs and partnered with a variety of prominent firms and governmental organizations (including Lehman Brothers , Renault and NASA), it failed to attain long-term profitability. Following its sale in 1983, Vallée entered the venture capital sphere as a partner at Sofinnova . From 1987 to 2010, he served as a general partner of several funds in Silicon Valley , most notably as

13348-545: The firm, assuming his responsibilities at once. Meanwhile, provisional government accused Louis Renault of collaborating with the Germans. In the frenzied atmosphere of those early post-liberation days, with many wild accusations, Renault was advised by his lawyers to present himself to a judge. He appeared before Judge Marcel Martin, on 22 September 1944 and was arrested on 23 September 1944, as were several other French automobile-industry leaders. Renault's harsh handling of

13490-410: The first Grand Prix motor racing event in a Renault AK 90CV in 1906 . Louis took full control of the company as the only remaining brother in 1906 when Fernand retired for health reasons. Fernand died in 1909 and Louis became the sole owner, renaming the company Société des Automobiles Renault (Renault Automobile Company). Renault fostered its reputation for innovation from very early on. At

13632-429: The flanks of the volcano Arsia Mons . The caves, named after loved ones of their discoverers, are collectively known as the "seven sisters". Cave entrances measure from 100 to 252 metres (328 to 827 ft) wide and they are estimated to be at least 73 to 96 metres (240 to 315 ft) deep. Because light does not reach the floor of most of the caves, they may extend much deeper than these lower estimates and widen below

13774-493: The following are the three primary periods: Geological activity is still taking place on Mars. The Athabasca Valles is home to sheet-like lava flows created about 200 million years ago. Water flows in the grabens called the Cerberus Fossae occurred less than 20 million years ago, indicating equally recent volcanic intrusions. The Mars Reconnaissance Orbiter has captured images of avalanches. Mars

13916-480: The group's collaboration with Renault was reduced, although established joint production projects were maintained. Prior its merging with Peugeot, Citroën sold to Renault the truck and bus manufacturer Berliet in December 1974, merging it with its subsidiary Saviem in 1978 to create Renault Véhicules Industriels , which became the only French manufacturer of heavy commercial vehicles. In 1976, Renault reorganised

14058-452: The improvement of the venerable AMC inline six – a Renault/Bendix-based port electronic fuel injection system (usually called Renix ) transformed it into a modern, competitive powerplant with a jump from 110 to 177 hp (82 to 132 kW) with less displacement (from 4.2 to 4.0 litres). The XJC Cherokee concept, which was conceived in 1983 as a successor to the XJ series, was also a joint collaboration with AMC and Renault engineers until

14200-436: The lander showed that the Martian soil has a basic pH of 7.7, and contains 0.6% perchlorate by weight, concentrations that are toxic to humans . Streaks are common across Mars and new ones appear frequently on steep slopes of craters, troughs, and valleys. The streaks are dark at first and get lighter with age. The streaks can start in a tiny area, then spread out for hundreds of metres. They have been seen to follow

14342-469: The manufacturer celebrated the 25th anniversary of its 1945 rebirth as the nationalised Régie Nationale des Usines Renault . The 1960s had been a decade of aggressive growth: a few months earlier, in October 1969, the manufacturer had launched the Renault 12 , combining the engineering philosophy of its hatchbacks with the more conservative "three-box" design. The four-door Renault 12 model slotted between

14484-636: The mid-seventies, the already broad-based company diversified into more industries and continued to expand globally, including South East Asia . The energy crisis led Renault to again attempt to attack the North American market. Despite the Dauphine's success in the United States in the late 1950s and an unsuccessful assembly project in Saint-Bruno-de-Montarville, Quebec (1964–72), Renault began to disappear from North America at

14626-418: The mineral jarosite . This forms only in the presence of acidic water, showing that water once existed on Mars. The Spirit rover found concentrated deposits of silica in 2007 that indicated wet conditions in the past, and in December 2011, the mineral gypsum , which also forms in the presence of water, was found on the surface by NASA's Mars rover Opportunity. It is estimated that the amount of water in

14768-613: The mineral olivine , which is known to be common on Mars, or by Martian life. Compared to Earth, its higher concentration of atmospheric CO 2 and lower surface pressure may be why sound is attenuated more on Mars, where natural sources are rare apart from the wind. Using acoustic recordings collected by the Perseverance rover, researchers concluded that the speed of sound there is approximately 240 m/s for frequencies below 240 Hz, and 250 m/s for those above. Auroras have been detected on Mars. Because Mars lacks

14910-436: The most popular while the least produced was the 18/ 24CV . The most expensive body style in each range was the closed car. Roadsters and tourers (torpedoes) were the cheapest. The London operation was important to Renault in 1928. The UK market was quite large and North America also received exports for the luxury car market. Lifted suspensions, enhanced cooling, and special bodies were common on vehicles sold abroad. Exports to

15052-427: The mountain is so large, with complex structure at its edges, giving a definite height to it is difficult. Its local relief, from the foot of the cliffs which form its northwest margin to its peak, is over 21 km (13 mi), a little over twice the height of Mauna Kea as measured from its base on the ocean floor. The total elevation change from the plains of Amazonis Planitia , over 1,000 km (620 mi) to

15194-431: The movement of dry dust. No partially degraded gullies have formed by weathering and no superimposed impact craters have been observed, indicating that these are young features, possibly still active. Other geological features, such as deltas and alluvial fans preserved in craters, are further evidence for warmer, wetter conditions at an interval or intervals in earlier Mars history. Such conditions necessarily require

15336-594: The new three spring rear suspension that considerably aided stability that was needed since some vehicles surpassed 90 mph (140 km/h). The straight 8-cylinder Reinastella was introduced in 1929 and expanded to a range culminating in 1939 Suprastella . Coachbuilders included Kellner , Labourdette , J. Rothschild et Fils and Renault bodies. Closed car Renault bodies were often trimmed with interior woodwork by Rothschild. In 1928, Renault introduced an upgraded specification to its "Stella" line. The Vivastella 's and Grand Renaults had upgraded interior fittings and

15478-514: The northwest, to the summit approaches 26 km (16 mi), roughly three times the height of Mount Everest , which in comparison stands at just over 8.8 kilometres (5.5 mi). Consequently, Olympus Mons is either the tallest or second-tallest mountain in the Solar System ; the only known mountain which might be taller is the Rheasilvia peak on the asteroid Vesta , at 20–25 km (12–16 mi). The dichotomy of Martian topography

15620-468: The old canal maps ), has a length of 4,000 kilometres (2,500 mi) and a depth of up to 7 kilometres (4.3 mi). The length of Valles Marineris is equivalent to the length of Europe and extends across one-fifth the circumference of Mars. By comparison, the Grand Canyon on Earth is only 446 kilometres (277 mi) long and nearly 2 kilometres (1.2 mi) deep. Valles Marineris was formed due to

15762-484: The only factories permanently expropriated by the French government. In subsequent years, the Renault family tried to have the nationalisation rescinded by French courts and receive compensation. In 1945, and again in 1961, the Courts responded that they had no authority to review the government's actions. Under the leadership of Pierre Lefaucheux , Renault experienced both a commercial resurgence and labor unrest , that

15904-842: The past. This paleomagnetism of magnetically susceptible minerals is similar to the alternating bands found on Earth's ocean floors . One hypothesis, published in 1999 and re-examined in October ;2005 (with the help of the Mars Global Surveyor ), is that these bands suggest plate tectonic activity on Mars four billion years ago, before the planetary dynamo ceased to function and the planet's magnetic field faded. The Phoenix lander returned data showing Martian soil to be slightly alkaline and containing elements such as magnesium , sodium , potassium and chlorine . These nutrients are found in soils on Earth. They are necessary for growth of plants. Experiments performed by

16046-513: The popular Extraterrestrial Hypothesis (or ETH). However, by 1969, Vallée's conclusions had changed, and he publicly stated that the ETH was too narrow and ignored too much data. Vallée began exploring the commonalities between UFOs, cults , religious movements , demons , angels , ghosts , cryptid sightings, and psychic phenomena . His speculation about these potential links was first detailed in his third UFO book, Passport to Magonia : From Folklore to Flying Saucers . As an alternative to

16188-562: The possibility of past or present life on Mars remains of great scientific interest. Since the late 20th century, Mars has been explored by uncrewed spacecraft and rovers , with the first flyby by the Mariner 4 probe in 1965, the first orbit by the Mars 2 probe in 1971, and the first landing by the Viking 1 probe in 1976. As of 2023, there are at least 11 active probes orbiting Mars or on

16330-464: The pre-war years. The first real commercial truck from the company was introduced in 1906. Renault were also an important pre-war manufacturer of aircraft engines . The firm entered the business in 1907 with the first of what would become a series of air-cooled V8 engines . In 1911 the Renault 90 hp became the world's first V12 aircraft engine when it was exhibited at the Salon de l’Aéronautique at

16472-566: The radiation of 1.84 millisieverts per day or 22 millirads per day during the flight to and from Mars. For comparison the radiation levels in low Earth orbit , where Earth's space stations orbit, are around 0.5 millisieverts of radiation per day. Hellas Planitia has the lowest surface radiation at about 0.342 millisieverts per day, featuring lava tubes southwest of Hadriacus Mons with potentially levels as low as 0.064 millisieverts per day, comparable to radiation levels during flights on Earth. Although better remembered for mapping

16614-462: The rivalries between capitalist collaboration and communist resistance; many of the scores settled predated the invasion. Responding to the chaotic situation at Renault, a 27 September 1944 meeting of the Council of Ministers ( fr ) took place under de Gaulle's presidency. Postwar European politics had quickly become polarised between communists and anti-communists, and in France de Gaulle

16756-467: The size of Earth's Arctic Ocean . This finding was derived from the ratio of protium to deuterium in the modern Martian atmosphere compared to that ratio on Earth. The amount of Martian deuterium (D/H = 9.3 ± 1.7 10 ) is five to seven times the amount on Earth (D/H = 1.56 10 ), suggesting that ancient Mars had significantly higher levels of water. Results from the Curiosity rover had previously found

16898-429: The size of the Moon's South Pole–Aitken basin , which would be the largest impact basin yet discovered if confirmed. It has been hypothesized that the basin was formed when Mars was struck by a Pluto -sized body about four billion years ago. The event, thought to be the cause of the Martian hemispheric dichotomy , created the smooth Borealis basin that covers 40% of the planet. A 2023 study shows evidence, based on

17040-422: The south polar ice cap, if melted, would be enough to cover most of the surface of the planet with a depth of 11 metres (36 ft). Water in its liquid form cannot prevail on the surface of Mars due to the low atmospheric pressure on Mars, which is less than 1% that of Earth, only at the lowest of elevations pressure and temperature is high enough for water being able to be liquid for short periods. Water in

17182-461: The southern highlands include detectable amounts of high-calcium pyroxenes . Localized concentrations of hematite and olivine have been found. Much of the surface is deeply covered by finely grained iron(III) oxide dust. Although Mars has no evidence of a structured global magnetic field , observations show that parts of the planet's crust have been magnetized, suggesting that alternating polarity reversals of its dipole field have occurred in

17324-469: The study of unidentified flying objects (UFOs), and unidentified anomalous phenomena (UAPs). Vallée was first noted for his defense of the scientific legitimacy of the extraterrestrial hypothesis and later for promoting the interdimensional hypothesis . Vallée was born in Pontoise , France in 1939. He completed his undergraduate degree in mathematics at the University of Paris in 1959 and received

17466-505: The study of Mars. Smaller craters are named for towns and villages of the world with populations of less than 100,000. Large valleys are named for the word "Mars" or "star" in various languages; smaller valleys are named for rivers. Large albedo features retain many of the older names but are often updated to reflect new knowledge of the nature of the features. For example, Nix Olympica (the snows of Olympus) has become Olympus Mons (Mount Olympus). The surface of Mars as seen from Earth

17608-513: The surface. However, later work suggested that the lineae may be dry, granular flows instead, with at most a limited role for water in initiating the process. A definitive conclusion about the presence, extent, and role of liquid water on the Martian surface remains elusive. Researchers suspect much of the low northern plains of the planet were covered with an ocean hundreds of meters deep, though this theory remains controversial. In March 2015, scientists stated that such an ocean might have been

17750-430: The surface. "Dena" is the only exception; its floor is visible and was measured to be 130 metres (430 ft) deep. The interiors of these caverns may be protected from micrometeoroids, UV radiation, solar flares and high energy particles that bombard the planet's surface. Mars lost its magnetosphere 4 billion years ago, possibly because of numerous asteroid strikes, so the solar wind interacts directly with

17892-625: The swelling of the Tharsis area, which caused the crust in the area of Valles Marineris to collapse. In 2012, it was proposed that Valles Marineris is not just a graben , but a plate boundary where 150 kilometres (93 mi) of transverse motion has occurred, making Mars a planet with possibly a two- tectonic plate arrangement. Images from the Thermal Emission Imaging System (THEMIS) aboard NASA's Mars Odyssey orbiter have revealed seven possible cave entrances on

18034-549: The time, cars were luxury items manufactured without assembly line advances. The price of the smallest Renaults at the time was 3000 francs (₣); an amount equal to ten years pay for the average worker. In 1905, the company introduced mass production techniques and Taylorism in 1913. In 1911, Renault visited Henry Ford at the Highland Park factory and adopted some of the manufacturing principles from his trip. Renault manufactured buses and commercial cargo vehicles in

18176-507: The upper mantle of Mars, represented by hydroxyl ions contained within Martian minerals, is equal to or greater than that of Earth at 50–300 parts per million of water, which is enough to cover the entire planet to a depth of 200–1,000 metres (660–3,280 ft). On 18 March 2013, NASA reported evidence from instruments on the Curiosity rover of mineral hydration , likely hydrated calcium sulfate , in several rock samples including

18318-506: The value of publicity that participation in motor racing could generate for their vehicles. Renault made itself known through succeeding in the first city-to-city races held in Switzerland, producing rapid sales growth. Both Louis and Marcel raced company vehicles, but Marcel was killed in an accident during the 1903 Paris-Madrid race . Although Louis never raced again, his company remained very involved, including Ferenc Szisz winning

18460-496: The war effort. In 1931, Renault introduced diesel engines for its commercial vehicles. Renault was one of the few French vehicle manufacturers that pursued the production of aircraft engines after World War I. In the late 1920s, it attempted to produce a high-power military engine to compete with the American Pratt & Whitney units, which proved unsuccessful, although its civil engines achieved better results. In

18602-420: The widespread presence of crater lakes across a large proportion of the surface, for which there is independent mineralogical, sedimentological and geomorphological evidence. Further evidence that liquid water once existed on the surface of Mars comes from the detection of specific minerals such as hematite and goethite , both of which sometimes form in the presence of water. In 2004, Opportunity detected

18744-481: Was a joke by the X-Files creator Chris Carter to name the characters after Vallee and Sheaffer. Sheaffer further states that "the M.P. who later arrested them [the characters] was Sgt. Hynek", a reference to ufologist J. Allen Hynek . Vallée was married to Janine Saley until her death in 2010. They have two children. Finance Novels Science Fiction Technical UFOlogy Mars Mars

18886-404: Was keen to resist Communist Party attempts to monopolise the political dividends available to resistance heroes: politically Billancourt was a communist stronghold. The government decided to "requisition" the Renault factories. A week later, on 4 October, Pierre Lefaucheux , a resistance leader with a background in engineering and top-level management, was appointed provisional administrator of

19028-463: Was later acquired by Michelin . Renault became again the largest car manufacturer, a position it would keep until the 1980s. Renault was finally affected by the Great Depression economic crisis in 1936. The company spun off Caudron and its foundry and aircraft engine divisions into related but autonomous operations, keeping its core automotive business. Between 1936 and 1938, a series of labour disputes, strikes, and worker unrest spread throughout

19170-436: Was marked by meteor impacts , valley formation, erosion, and the possible presence of water oceans . The Hesperian period (3.5 to 3.3–2.9 billion years ago) was dominated by widespread volcanic activity and flooding that carved immense outflow channels . The Amazonian period, which continues to the present, has been marked by the wind as a dominant influence on geological processes . Due to Mars's geological history,

19312-629: Was probably the root cause of the incision in almost all cases. Along craters and canyon walls, there are thousands of features that appear similar to terrestrial gullies . The gullies tend to be in the highlands of the Southern Hemisphere and face the Equator; all are poleward of 30° latitude. A number of authors have suggested that their formation process involves liquid water, probably from melting ice, although others have argued for formation mechanisms involving carbon dioxide frost or

19454-399: Was real, physical, but not ET. So he said, 'You're probably right, but that's not what the public is expecting — this is Hollywood and I want to give people something that's close to what they expect.'" Episode " Jose Chung's From Outer Space " of X-Files which aired on April 12, 1996 had fake alien pilots named Jacques Sheaffer and Robert Vallee. According to Robert Sheaffer this

19596-437: Was reported that InSight had detected and recorded over 450 marsquakes and related events. Beneath the crust is a silicate mantle responsible for many of the tectonic and volcanic features on the planet's surface. The upper Martian mantle is a low-velocity zone , where the velocity of seismic waves is lower than surrounding depth intervals. The mantle appears to be rigid down to the depth of about 250 km, giving Mars
