61-553: The Arnhem Space Centre is a commercial spaceport near Nhulunbuy , in Arnhem Land , Australia . The facility is owned and operated by Equatorial Launch Australia , both of which were founded by Scott Wallis in 2016. ASC was the location of NASA 's first non-orbital sounding rocket launch from a commercial spaceport outside the United States, which took place on 27 June 2022. The project took six years to develop, and

122-411: A is more than R /2. The specific orbital energy ϵ {\displaystyle \epsilon } is given by: ε = − μ 2 a > − μ R {\displaystyle \varepsilon =-{\mu \over {2a}}>-{\mu \over {R}}\,\!} where μ {\displaystyle \mu \,\!}

183-410: A LEO. On a 10,000-kilometer intercontinental flight, such as that of an intercontinental ballistic missile or possible future commercial spaceflight , the maximum speed is about 7 km/s, and the maximum altitude may be more than 1300 km. Any spaceflight that returns to the surface, including sub-orbital ones, will undergo atmospheric reentry . The speed at the start of the reentry is basically

244-867: A Node 3 spaceport on the Martian moon Phobos to enable refueling and resupply prior to Mars surface landings, missions beyond Mars, and return trips to Earth. In addition to propellant mining and refueling, the network of spaceports could provide services such as power storage and distribution, in-space assembly and repair of spacecraft, communications relay, shelter, construction and leasing of infrastructure, maintaining spacecraft positioned for future use, and logistics. Space launch facilities have been colonial developments and have also been impacting its surroundings by destroying or polluting their environment, creating precarious cleanup situations.

Phantom has links to the US Department of Defense , and an ELA spokesperson said that the launch site could one day be used for missile-testing and development. Phantom hopes to mass-produce rockets, which could be fired from the ASC site by 2025. While the main focus is on commercial uses, the potential for involvement in military use has raised concerns among

366-471: A crew of two pilots, to an altitude of 200 km (65,000 ft) using captured V-2 . In 2004, a number of companies worked on vehicles in this class as entrants to the Ansari X Prize competition. The Scaled Composites SpaceShipOne was officially declared by Rick Searfoss to have won the competition on October 4, 2004, after completing two flights within a two-week period. In 2005, Sir Richard Branson of

427-454: A distinct boundary between atmospheric flight and spaceflight . During freefall the trajectory is part of an elliptic orbit as given by the orbit equation . The perigee distance is less than the radius of the Earth R including atmosphere, hence the ellipse intersects the Earth, and hence the spacecraft will fail to complete an orbit. The major axis is vertical, the semi-major axis

488-493: A driving factor in spaceport placement because most of the delta-v for a launch is spent on achieving the required horizontal orbital speed . The small gain from a few kilometers of extra altitude does not usually off-set the logistical costs of ground transport in mountainous terrain. Many spaceports have been placed at existing military installations, such as intercontinental ballistic missile ranges, which are not always physically ideal sites for launch. A rocket launch site

549-500: A flight is attained at the lowest altitude of this free-fall trajectory, both at the start and at the end of it. If one's goal is simply to "reach space", for example in competing for the Ansari X Prize , horizontal motion is not needed. In this case the lowest required delta-v, to reach 100 km altitude, is about 1.4  km/s . Moving slower, with less free-fall, would require more delta-v. Compare this with orbital spaceflights:

610-511: A lift off from Texas and a simulated soft touchdown in the Indian Ocean 66 minutes after liftoff. Sub-orbital flights can last from just seconds to days. Pioneer 1 was NASA 's first space probe , intended to reach the Moon . A partial failure caused it to instead follow a sub-orbital trajectory, reentering the Earth's atmosphere 43 hours after launch. To calculate the time of flight for

671-482: A low Earth orbit (LEO), with an altitude of about 300 km, needs a speed around 7.7 km/s, requiring a delta-v of about 9.2 km/s. (If there were no atmospheric drag the theoretical minimum delta-v would be 8.1 km/s to put a craft into a 300-kilometer high orbit starting from a stationary point like the South Pole. The theoretical minimum can be up to 0.46 km/s less if launching eastward from near

732-765: A minimum-delta-v trajectory, according to Kepler's third law , the period for the entire orbit (if it did not go through the Earth) would be: period = ( semi-major axis R ) 3 2 × period of low Earth orbit = ( 1 + sin ⁡ θ 2 ) 3 2 2 π R g {\displaystyle {\text{period}}=\left({\frac {\text{semi-major axis}}{R}}\right)^{\frac {3}{2}}\times {\text{period of low Earth orbit}}=\left({\frac {1+\sin \theta }{2}}\right)^{\frac {3}{2}}2\pi {\sqrt {\frac {R}{g}}}} Using Kepler's second law , we multiply this by

793-478: A quarter of the way around the Earth, and 42 minutes for going halfway around. For short distances, this expression is asymptotic to 2 d / g {\displaystyle {\sqrt {2d/g}}} . From the form involving arccosine, the derivative of the time of flight with respect to d (or θ) goes to zero as d approaches 20 000  km (halfway around the world). The derivative of Δ v also goes to zero here. So if d = 19 000  km ,

854-471: A table of spaceports and launch complexes for vertical launchers with documented achieved launches of humans to space (more than 100 km (62 mi) altitude). The sorting order is spaceport by spaceport according to the time of the first human launch. † Three of the Soyuz missions were uncrewed and are not counted ( Soyuz 2 , Soyuz 20 , Soyuz 34 ). ‡ STS-51-L ( Challenger ) failed to reach orbit and

915-559: Is a spaceflight in which the spacecraft reaches outer space , but its trajectory intersects the surface of the gravitating body from which it was launched. Hence, it will not complete one orbital revolution, will not become an artificial satellite nor will it reach escape velocity . For example, the path of an object launched from Earth that reaches the Kármán line (about 83 km [52 mi] – 100 km [62 mi] above sea level ), and then falls back to Earth,

976-423: Is as scientific sounding rockets . Scientific sub-orbital flights began in the 1920s when Robert H. Goddard launched the first liquid fueled rockets, however they did not reach space altitude. In the late 1940s, captured German V-2 ballistic missiles were converted into V-2 sounding rockets which helped lay the foundation for modern sounding rockets. Today there are dozens of different sounding rockets on

1037-435: Is between 0 and μ 2 R {\displaystyle \mu \over {2R}\,\!} . To minimize the required delta-v (an astrodynamical measure which strongly determines the required fuel ), the high-altitude part of the flight is made with the rockets off (this is technically called free-fall even for the upward part of the trajectory). (Compare with Oberth effect .) The maximum speed in

1098-566: Is built as far as possible away from major population centers in order to mitigate risk to bystanders should a rocket experience a catastrophic failure. In many cases a launch site is built close to major bodies of water to ensure that no components are shed over populated areas. Typically a spaceport site is large enough that, should a vehicle explode, it will not endanger human lives or adjacent launch pads. Planned sites of spaceports for sub-orbital tourist spaceflight often make use of existing ground infrastructure, including runways. The nature of

1159-624: Is considered a sub-orbital spaceflight. Some sub-orbital flights have been undertaken to test spacecraft and launch vehicles later intended for orbital spaceflight . Other vehicles are specifically designed only for sub-orbital flight; examples include crewed vehicles, such as the X-15 and SpaceShipTwo , and uncrewed ones, such as ICBMs and sounding rockets . Flights which attain sufficient velocity to go into low Earth orbit , and then de-orbit before completing their first full orbit, are not considered sub-orbital. Examples of this include flights of

1220-468: Is defined as a missile that can hit a target at least 5500 km away, and according to the above formula this requires an initial speed of 6.1 km/s. Increasing the speed to 7.9 km/s to attain any point on Earth requires a considerably larger missile because the amount of fuel needed goes up exponentially with delta-v (see Rocket equation ). The initial direction of a minimum-delta-v trajectory points halfway between straight up and straight toward

1281-728: Is equipped to launch both sub-orbital flights and small orbital flights . The site's location, only 12 degrees south of the equator , is preferable for orbital rockets launching east, as extra speed is provided due to the spin of Earth . It is the first commercial spaceport in Australia, and as of July 2022 the only one.. Scott Wallis, the founder, was a flight test navigator with the Royal Australian Airforce and had experience developing spaceports. His understanding of sub orbital rocketry led him to believe that substantial fuel can be saved by launching from as close to

Crewed Missions failed to reach Kármán line: Soyuz T-10a (1983) STS-51-L (1986) Soyuz MS-10 (2018) The following is a table of spaceports with a documented achieved launch to orbit. The table is sorted according to the time of the first launch that achieved satellite orbit insertion. The first column gives

1464-425: Is similar to an ICBM. ICBMs have delta-v's somewhat less than orbital; and therefore would be somewhat cheaper than the costs for reaching orbit, but the difference is not large. Due to the high cost of spaceflight, suborbital flights are likely to be initially limited to high value, very high urgency cargo deliveries such as courier flights, military fast-response operations or space tourism . The SpaceLiner

Almost always a < R , corresponding to a lower ϵ {\displaystyle \epsilon } than the minimum for a full orbit, which is − μ 2 R {\displaystyle -{\mu \over {2R}}\,\!} Thus the net extra specific energy needed compared to just raising the spacecraft into space

1586-447: Is the acceleration of gravity at the Earth's surface). The Δ v increases with range, leveling off at 7.9 km/s as the range approaches 20 000  km (halfway around the world). The minimum-delta-v trajectory for going halfway around the world corresponds to a circular orbit just above the surface (of course in reality it would have to be above the atmosphere). See lower for the time of flight. An intercontinental ballistic missile

1647-557: Is the major European spaceport, with satellite launches that benefit from the location 5 degrees north of the equator. In October 2003 the Jiuquan Satellite Launch Center achieved the first Chinese human spaceflight. Breaking with tradition, in June 2004 on a runway at Mojave Air and Space Port , California, a human was for the first time launched to space in a privately funded, suborbital spaceflight, that

1708-454: The Earth's rotational speed (465 m/s at the equator). Such launches also provide a desirable orientation for arriving at a geostationary orbit . For polar orbits and Molniya orbits this does not apply. In principle, advantages of high altitude launch are reduced vertical distance to travel and a thinner atmosphere for the rocket to penetrate. However, altitude of the launch site is not

1769-554: The Fractional Orbital Bombardment System . A flight that does not reach space is still sometimes called sub-orbital, but cannot officially be classified as a "sub-orbital spaceflight". Usually a rocket is used, but some experimental sub-orbital spaceflights have also been achieved via the use of space guns . By definition, a sub-orbital spaceflight reaches an altitude higher than 100 km (62 mi) above sea level . This altitude, known as

1830-738: The Moon , Mars , orbiting the Earth, at Sun-Earth and Earth-Moon Lagrange points , and at other locations in the Solar System . Human-tended outposts on the Moon or Mars, for example, will be spaceports by definition. The 2012 Space Studies Program of the International Space University studied the economic benefit of a network of spaceports throughout the solar system beginning from Earth and expanding outwardly in phases, within its team project Operations And Service Infrastructure for Space (OASIS). Its analysis claimed that

1891-461: The V-2 rocket , just reaching space but with a range of about 330 km, the maximum speed was 1.6 km/s. Scaled Composites SpaceShipTwo which is under development will have a similar free-fall orbit but the announced maximum speed is 1.1 km/s (perhaps because of engine shut-off at a higher altitude). For larger ranges, due to the elliptic orbit the maximum altitude can be much more than for

1952-656: The Virgin Group announced the creation of Virgin Galactic and his plans for a 9-seat capacity SpaceShipTwo named VSS Enterprise . It has since been completed with eight seats (one pilot, one co-pilot and six passengers) and has taken part in captive-carry tests and with the first mother-ship WhiteKnightTwo , or VMS Eve . It has also completed solitary glides, with the movable tail sections in both fixed and "feathered" configurations. The hybrid rocket motor has been fired multiple times in ground-based test stands, and

2013-464: The flight phases before and after the free-fall can vary. For an intercontinental flight the boost phase takes 3 to 5 minutes, the free-fall (midcourse phase) about 25 minutes. For an ICBM the atmospheric reentry phase takes about 2 minutes; this will be longer for any soft landing, such as for a possible future commercial flight. Test flight 4 of the SpaceX 'Starship' performed such a flight with

2074-558: The Kármán line, was chosen by the Fédération Aéronautique Internationale because it is roughly the point where a vehicle flying fast enough to support itself with aerodynamic lift from the Earth's atmosphere would be flying faster than orbital speed . The US military and NASA award astronaut wings to those flying above 50 mi (80 km), although the U.S. State Department does not show

2135-406: The Moon are sometimes called spaceports, in particular if intended as a base for further journeys. The term rocket launch site is used for any facility from which rockets are launched. It may contain one or more launch pads or suitable sites to mount a transportable launch pad. It is typically surrounded by a large safety area, often called a rocket range or missile range . The range includes

2196-406: The altitude required to qualify as reaching space. The flight path will be either vertical or very steep, with the spacecraft landing back at its take-off site. The spacecraft will shut off its engines well before reaching maximum altitude, and then coast up to its highest point. During a few minutes, from the point when the engines are shut off to the point where the atmosphere begins to slow down

2257-402: The angle that the projectile is to go around the Earth, so in degrees it is 45°× d / 10 000  km . The minimum-delta-v trajectory corresponds to an ellipse with one focus at the centre of the Earth and the other at the point halfway between the launch point and the destination point (somewhere inside the Earth). (This is the orbit that minimizes the semi-major axis, which is equal to the sum of

2318-958: The area over which launched rockets are expected to fly, and within which some components of the rockets may land. Tracking stations are sometimes located in the range to assess the progress of the launches. Major spaceports often include more than one launch complex , which can be rocket launch sites adapted for different types of launch vehicles . (These sites can be well-separated for safety reasons.) For launch vehicles with liquid propellant, suitable storage facilities and, in some cases, production facilities are necessary. On-site processing facilities for solid propellants are also common. A spaceport may also include runways for takeoff and landing of aircraft to support spaceport operations, or to enable support of HTHL or horizontal takeoff and vertical landing (HTVL) winged launch vehicles. The first rockets to reach space were V-2 rockets launched from Peenemünde , Germany in 1944 during World War II . After

2379-519: The cosmodrome was initially held secret. Guesses to its location were misdirected by a name in common with a mining town 320 km away. The position became known in 1957 outside the Soviet Union only after U-2 planes had identified the site by following railway lines in the Kazakh SSR , although Soviet authorities did not confirm the location for decades. The Baikonur Cosmodrome achieved

2440-473: The destination point (which is below the horizon). Again, this is the case if the Earth's rotation is ignored. It is not exactly true for a rotating planet unless the launch takes place at a pole. In a vertical flight of not too high altitudes, the time of the free-fall is both for the upward and for the downward part the maximum speed divided by the acceleration of gravity , so with a maximum speed of 1 km/s together 3 minutes and 20 seconds. The duration of

2501-1764: The distances from a point on the orbit to the two foci. Minimizing the semi-major axis minimizes the specific orbital energy and thus the delta-v, which is the speed of launch.) Geometrical arguments lead then to the following (with R being the radius of the Earth, about 6370 km): major axis = ( 1 + sin ⁡ θ ) R {\displaystyle {\text{major axis}}=(1+\sin \theta )R} minor axis = R 2 ( sin ⁡ θ + sin 2 ⁡ θ ) = R sin ⁡ ( θ ) semi-major axis {\displaystyle {\text{minor axis}}=R{\sqrt {2\left(\sin \theta +\sin ^{2}\theta \right)}}={\sqrt {R\sin(\theta ){\text{semi-major axis}}}}} distance of apogee from centre of Earth = R 2 ( 1 + sin ⁡ θ + cos ⁡ θ ) {\displaystyle {\text{distance of apogee from centre of Earth}}={\frac {R}{2}}(1+\sin \theta +\cos \theta )} altitude of apogee above surface = ( sin ⁡ θ 2 − sin 2 ⁡ θ 2 ) R = ( 1 2 sin ⁡ ( θ + π 4 ) − 1 2 ) R {\displaystyle {\text{altitude of apogee above surface}}=\left({\frac {\sin \theta }{2}}-\sin ^{2}{\frac {\theta }{2}}\right)R=\left({\frac {1}{\sqrt {2}}}\sin \left(\theta +{\frac {\pi }{4}}\right)-{\frac {1}{2}}\right)R} The altitude of apogee

In late 1945, a group led by M. Tikhonravov K. and N. G. Chernysheva at the Soviet NII-4 academy (dedicated to rocket artillery science and technology), began work on a stratospheric rocket project, VR-190 , aimed at vertical flight by

For the Apollo programme, an adjacent spaceport, Kennedy Space Center , was constructed, and achieved the first crewed mission to the lunar surface ( Apollo 11 ) in July 1969. It was the base for all Space Shuttle launches and most of their runway landings. For details on the launch complexes of the two spaceports, see List of Cape Canaveral and Merritt Island launch sites . The Guiana Space Centre in Kourou, French Guiana,

The rocket was a Black Brant IX carrying a X-ray Quantum Calorimeter (XQC) instrument for UW–Madison for the purpose of X-ray astronomy for a brief period ( 5-20 min) in space. The mission was a suborbital flight with apogee of 203 mi (327 km). It

2745-498: The equator.) For sub-orbital spaceflights covering a horizontal distance the maximum speed and required delta-v are in between those of a vertical flight and a LEO. The maximum speed at the lower ends of the trajectory are now composed of a horizontal and a vertical component. The higher the horizontal distance covered, the greater the horizontal speed will be. (The vertical velocity will increase with distance for short distances but will decrease with distance at longer distances.) For

2806-539: The first launch of a human into space ( Yuri Gagarin ) in 1961. The launch complex used, Site 1, has reached a special symbolic significance and is commonly called Gagarin's Start . Baikonur was the primary Soviet cosmodrome, and is still frequently used by Russia under a lease arrangement with Kazakhstan. In response to the early Soviet successes, the United States built up a major spaceport complex at Cape Canaveral in Florida. A large number of uncrewed flights, as well as

2867-561: The first phase, placing the "Node 1" spaceport with space tug services in low Earth orbit (LEO), would be commercially profitable and reduce transportation costs to geosynchronous orbit by as much as 44% (depending on the launch vehicle). The second phase would add a Node 2 spaceport on the lunar surface to provide services including lunar ice mining and delivery of rocket propellants back to Node 1. This would enable lunar surface activities and further reduce transportation costs within and out from cislunar space . The third phase would add

2928-632: The fourth DEUCE mission, intended by NASA to investigate and analyze the Alpha Centauri star system's ultraviolet spectrum. As of July 2022 the long term future of the site was not known, but Equatorial Launch Australia had indicated that there are other space companies interested in using the rocket launch pad , and NASA has confirmed that it will use the facility again in the future. In August 2023, ELA announced that there would be launches by early 2025 by INNOSPACE of South Korea . In 2023 ELA signed an agreement Phantom Space Corporation ,

A launch is counted as one also in cases where the payload consists of multiple satellites. 4 Qaem 100 The following table shows spaceports with documented achieved launches of humans to at least 100 km altitude, starting from a horizontal runway. All the flights were sub-orbital . Spaceports have been proposed for locations on

3050-475: The length of the minimum-delta-v trajectory will be about 19 500  km , but it will take only a few seconds less time than the trajectory for d = 20 000  km (for which the trajectory is 20 000  km long). While there are a great many possible sub-orbital flight profiles, it is expected that some will be more common than others. The first sub-orbital vehicles which reached space were ballistic missiles . The first ballistic missile to reach space

3111-642: The local community. Spaceport A spaceport or cosmodrome is a site for launching or receiving spacecraft , by analogy to a seaport for ships or an airport for aircraft. The word spaceport , and even more so cosmodrome , has traditionally been used for sites capable of launching spacecraft into orbit around Earth or on interplanetary trajectories. However, rocket launch sites for purely sub-orbital flights are sometimes called spaceports, as in recent years new and proposed sites for suborbital human flights have been frequently referred to or named "spaceports". Space stations and proposed future bases on

3172-399: The local view from 100 km (62 mi) altitude is also a factor to consider. The space tourism industry (see List of private spaceflight companies ) is being targeted by spaceports in numerous locations worldwide. e.g. Spaceport America , New Mexico. The establishment of spaceports for tourist trips raises legal issues, which are only beginning to be addressed. The following is

3233-478: The market, from a variety of suppliers in various countries. Typically, researchers wish to conduct experiments in microgravity or above the atmosphere. Research, such as that done for the X-20 Dyna-Soar project suggests that a semi-ballistic sub-orbital flight could travel from Europe to North America in less than an hour. However, the size of rocket, relative to the payload, necessary to achieve this,

3294-445: The maximum speed of the flight. The aerodynamic heating caused will vary accordingly: it is much less for a flight with a maximum speed of only 1 km/s than for one with a maximum speed of 7 or 8 km/s. The minimum delta-v and the corresponding maximum altitude for a given range can be calculated, d , assuming a spherical Earth of circumference 40 000  km and neglecting the Earth's rotation and atmosphere.

At Cape Canaveral, SpaceX in 2015 made the first successful landing and recovery of a first stage used in a vertical satellite launch. Rockets can most easily reach satellite orbits if launched near the equator in an easterly direction, as this maximizes use of
