The Center for Women In Technology ( CWIT ) was established at the University of Maryland, Baltimore County in July 1998. The center's original name was the "Center for Women and Information Technology", and it was founded to encourage women as both developers of information technology and to women's experiences as users of IT. The original CWIT site included a large number of resources and links and served as a clearinghouse about women and information technology. This work included focusing on K-12 education as well as supporting university students, and work force advancement and retention. The center has included engineering majors since 2006, and in 2011 its name was changed to the Center for Women In Technology.

It is open to high school seniors planning to major in one of these areas of study. Scholars in the program receive mentoring from university faculty and IT professionals as well as participate in specially designed activities and events. CWIT and

196-494: A Herndon mailing address ), works on "the entire life cycle of civil and defense platforms and capabilities through a range of services". Vinnell , a Northrop Grumman subsidiary, provides training and communications for the military. In 2003, it landed a $ 48 million contract to train the Iraqi Army . In 2005, the company won a $ 2 billion contract with Virginia to overhaul most of the state's IT operations. Later that year,

294-484: A dewar with an extremely cold substance, such as liquid helium . The coolant will slowly vaporize, limiting the lifetime of the instrument from as short as a few months to a few years at most. It is also possible to maintain a low temperature by designing the spacecraft to enable near-infrared observations without a supply of coolant, as with the extended missions of the Spitzer Space Telescope and

392-400: A "new sky" for astronomers. However, there is a challenge involved in the design of infrared telescopes: they need to stay extremely cold, and the longer the wavelength of infrared, the colder they need to be. If not, the background heat of the device itself overwhelms the detectors, making it effectively blind. This can be overcome by careful design. One method is to put the key instruments in

490-579: A 6.5-meter-diameter (21 ft) mirror, compared with Hubble's 2.4 m (7 ft 10 in). This gives Webb a light-collecting area of about 25 m (270 sq ft), about six times that of Hubble. Unlike Hubble, which observes in the near ultraviolet and visible (0.1 to 0.8  μm ), and near infrared (0.8–2.5 μm) spectra, Webb observes a lower frequency range, from long-wavelength visible light (red) through mid-infrared (0.6–28.5 μm). The telescope must be kept extremely cold, below 50 K (−223 °C; −370 °F), so that

588-586: A core NASA activity. In 2003, NASA awarded TRW the US$ 824.8 million prime contract for Webb. The design called for a de-scoped 6.1 m (20 ft) primary mirror and a launch date of 2010. Later that year, TRW was acquired by Northrop Grumman in a hostile bid and became Northrop Grumman Space Technology. Development was managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, with John C. Mather as its project scientist. The primary contractor

686-476: A fully baffled 4 m (13 ft) aperture infrared telescope that would recede to an orbit at 3 Astronomical unit (AU). This distant orbit would have benefited from reduced light noise from zodiacal dust . Other early plans called for a NEXUS precursor telescope mission. Correcting the flawed optics of the Hubble Space Telescope (HST) in its first years played a significant role in

784-401: A joint venture, which grew "from $ 100 million in revenue in 2000 to approximately $ 500 million in fiscal year 2007." In 2000, NG acquired Federal Data Corporation, Navia Aviation As, Comptek Research, Inc., and Sterling Software, Inc.

The NASA Goddard Space Flight Center in Maryland managed telescope development, while

1372-573: A very thin layer of glass on top was first looked at, but beryllium was selected at the end. The mid-1990s era of "faster, better, cheaper" produced the NGST concept, with an 8 m (26 ft) aperture to be flown to L 2 , roughly estimated to cost US$ 500 million. In 1997, NASA worked with the Goddard Space Flight Center, Ball Aerospace & Technologies , and TRW to conduct technical requirement and cost studies of

1470-416: A wide field. The secondary mirror is 0.74 m (2.4 ft) in diameter. In addition, there is a fine steering mirror which can adjust its position many times per second to provide image stabilization . Point light sources in images taken by Webb have six diffraction spikes plus two fainter ones, due to the hexagonal shape of the primary mirror segments. The Integrated Science Instrument Module (ISIM)

1568-510: Is a framework that provides electrical power, computing resources, cooling capability as well as structural stability to the Webb telescope. It is made with bonded graphite-epoxy composite attached to the underside of Webb's telescope structure. The ISIM holds the four science instruments and a guide camera. NIRCam and MIRI feature starlight-blocking coronagraphs for observation of faint targets such as extrasolar planets and circumstellar disks very close to bright stars. The spacecraft bus

1666-457: Is designed primarily for near-infrared astronomy , but can also see orange and red visible light, as well as the mid-infrared region, depending on the instrument being used. It can detect objects up to 100 times fainter than Hubble can, and objects much earlier in the history of the universe , back to redshift z≈20 (about 180 million years cosmic time after the Big Bang ). For comparison,

1764-489: Is designed to cool itself without a dewar, using a combination of sunshields and radiators, with the mid-infrared instrument using an additional cryocooler. Webb's delays and cost increases have been compared to those of its predecessor, the Hubble Space Telescope .

2156-564: Is opaque in many infrared bands (see figure at right). Even where the atmosphere is transparent, many of the target chemical compounds, such as water, carbon dioxide, and methane, also exist in the Earth's atmosphere, vastly complicating analysis. Existing space telescopes such as Hubble cannot study these bands since their mirrors are insufficiently cool (the Hubble mirror is maintained at about 15 °C [288 K; 59 °F]) which means that

2254-529: Is the primary support component of the JWST, hosting a multitude of computing, communication, electric power, propulsion, and structural parts. Along with the sunshield, it forms the spacecraft element of the space telescope . The spacecraft bus is on the Sun-facing "warm" side of the sunshield and operates at a temperature of about 300 K (27 °C; 80 °F). The structure of the spacecraft bus has

2352-418: Is therefore composed of 18 hexagonal segments (a technique pioneered by Guido Horn d'Arturo ), which unfolded after the telescope was launched. Image plane wavefront sensing through phase retrieval is used to position the mirror segments in the correct location using precise actuators . Subsequent to this initial configuration, they only need occasional updates every few days to retain optimal focus. This

2450-586: Is unlike terrestrial telescopes, for example the Keck telescopes , which continually adjust their mirror segments using active optics to overcome the effects of gravitational and wind loading. The Webb telescope uses 132 small actuation motors to position and adjust the optics. The actuators can position the mirror with 10  nanometer accuracy. Webb's optical design is a three-mirror anastigmat , which makes use of curved secondary and tertiary mirrors to deliver images that are free from optical aberrations over

The longer the wavelength of the spectrum, the larger the information-gathering surface required (mirrors in the infrared spectrum or antenna area in the millimeter and radio ranges) for an image comparable in clarity to the visible spectrum of the Hubble Space Telescope. The Webb was launched on 25 December 2021 on an Ariane 5 rocket from Kourou , French Guiana. In January 2022 it arrived at its destination,

6566-444: The mechanical integration of the telescope was completed, something that was scheduled to be done 12 years before in 2007. After construction was completed, Webb underwent final tests at Northrop Grumman's historic Space Park in Redondo Beach, California. A ship carrying the telescope left California on 26 September 2021, passed through the Panama Canal , and arrived in French Guiana on 12 October 2021. NASA's lifetime cost for

6664-445: The near-IR and mid-IR sensitivity to be able to observe virtually all known Kuiper Belt Objects . In addition, it can observe opportunistic and unplanned targets within 48 hours of a decision to do so, such as supernovae and gamma ray bursts . Webb operates in a halo orbit , circling around a point in space known as the Sun–Earth L 2 Lagrange point , approximately 1,500,000 km (930,000 mi) beyond Earth's orbit around

6762-420: The new company acquired substantially all of the defense and electronics systems business of Westinghouse Electric Corporation, Westinghouse Electronic Systems , a major manufacturer of radar systems, for $ 2.9 billion, and Xetron Corporation . In 1997, the defense computer contractor Logicon was added, which had acquired Geodynamics Corporation in March 1996 and Syscon Corporation in February 1995. Northrop

6860-431: The observatory were unchanged. Following the re-planning, the project was independently reviewed in April 2006. In the 2005 re-plan, the life-cycle cost of the project was estimated at US$ 4.5 billion. This comprised approximately US$ 3.5 billion for design, development, launch and commissioning, and approximately US$ 1.0 billion for ten years of operations. The ESA agreed in 2004 to contributing about €300 million, including

6958-468: The observatory, as was done for Hubble, would not be possible, and according to NASA Associate Administrator Thomas Zurbuchen , despite best efforts, an uncrewed remote mission was found to be beyond available technology at the time Webb was designed. During the long Webb testing period, NASA officials referred to the idea of a servicing mission, but no plans were announced. Since the successful launch, NASA has stated that nevertheless limited accommodation

7056-686: The primary contractor for the James Webb Space Telescope . In October 2015, the US Military announced it had awarded Northrop Grumman the contract for the successor to the B-1 and B-52 , subsequently identified as the B-21 . The initial value is $ 21.4 billion, and could eventually be worth up to $ 80 billion. In September 2017, Northrop announced its intention to acquire missile and rocket manufacturer Orbital ATK Inc for $ 9.2 billion: $ 7.8 billion in cash plus $ 1.4 billion in net debt. On November 29, 2017,

7154-486: The shadow of the sunshield limits the field of regard of Webb at any given time. The telescope can see 40 percent of the sky from any one position, but can see all of the sky over a period of six months. Webb's primary mirror is a 6.5 m (21 ft)-diameter gold-coated beryllium reflector with a collecting area of 25.4 m (273 sq ft). If it had been designed as a single, large mirror, it would have been too large for existing launch vehicles. The mirror

7252-770: The spacecraft and the science instruments." The desire for a large infrared space telescope traces back decades. In the United States, the Space Infrared Telescope Facility (later called the Spitzer Space Telescope ) was planned while the Space Shuttle was in development, and the potential for infrared astronomy was acknowledged at that time. Unlike ground telescopes, space observatories are free from atmospheric absorption of infrared light. Space observatories opened

7350-426: The structure, yet still maintain uninterrupted solar power and Earth communications on its sun-facing side. This arrangement keeps the temperature of the spacecraft constant and below the 50 K (−223 °C; −370 °F) necessary for faint infrared observations. To make observations in the infrared spectrum , Webb must be kept under 50 K (−223.2 °C; −369.7 °F); otherwise, infrared radiation from

7448-437: The structures on the dark side is critical to maintaining precise alignment of the primary mirror segments. The sunshield consists of five layers, each approximately as thin as a human hair. Each layer is made of Kapton E film, coated with aluminum on both sides. The two outermost layers have an additional coating of doped silicon on the Sun-facing sides, to better reflect the Sun's heat back into space. Accidental tears of

7546-622: The tanker program and in March 2010, Northrop Grumman announced it was withdrawing from the competition, deeming the revised requirements to be weighted in favor of the Boeing KC-46 . On January 1, 2006, Northrop Grumman opened its business sector called 'Technical Services'. Northrop Grumman and Boeing collaborated on a design concept for NASA 's upcoming Orion spacecraft (previously the Crew Exploration Vehicle), but

7644-1043: The teams working on that project were dispersed, as USAF's focus turned to a long-range strike instead. Northrop Grumman was one of two teams competing for the Long Range Strike Bomber , and in October 2015 won the contract for the Long Range Strike Bomber. On July 20, 2007, Northrop Grumman became the sole owner of Burt Rutan 's Scaled Composites . In 2007, Northrop Grumman created 'National Workforce Centers' as an alternative to offshoring . Locations are Auburn , Alabama; Corsicana , Texas; Fairmont , West Virginia; Helena , Montana; Johnstown , Pennsylvania; and Lebanon, Virginia . The Rapid City, South Dakota location closed in January 2012. In July 2008, three of four Northrop Grumman employees ( Thomas Howes , Marc Gonsalves and Keith Stansell ) were freed during Operation Jaque after five years of captivity following their aircraft crash in

7742-485: The telescope itself radiates strongly in the relevant infrared bands. Webb can also observe objects in the Solar System at an angle of more than 85° from the Sun and having an apparent angular rate of motion less than 0.03 arc seconds per second. This includes Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, their satellites , and comets , asteroids and minor planets at or beyond the orbit of Mars . Webb has

7840-435: The telescope itself would overwhelm its instruments. Its large sunshield blocks light and heat from the Sun, Earth, and Moon, and its position near the Sun–Earth L 2 keeps all three bodies on the same side of the spacecraft at all times. Its halo orbit around the L 2 point avoids the shadow of the Earth and Moon, maintaining a constant environment for the sunshield and solar arrays. The resulting stable temperature for

7938-479: The three different concepts, and in 1999 selected Lockheed Martin and TRW for preliminary concept studies. Launch was at that time planned for 2007, but the launch date was pushed back many times (see table further down ). In 2002, the project was renamed after NASA's second administrator (1961–1968), James E. Webb (1906–1992). Webb led the agency during the Apollo program and established scientific research as

8036-398: The time it was sent into orbit in 1990, the cost was about four times that. In addition, new instruments and servicing missions increased the cost to at least US$ 9 billion by 2006 (equivalent to $ 13,602,509,000 in 2023). Discussions of a Hubble follow-on started in the 1980s, but serious planning began in the early 1990s. The Hi-Z telescope concept was developed between 1989 and 1994:

8134-411: The upcoming decade) included further development of the scientific program for what became known as the Next Generation Space Telescope, and advancements in relevant technologies by NASA. As it matured, studying the birth of galaxies in the young universe , and searching for planets around other stars – the prime goals coalesced as "Origins" by HST & Beyond became prominent. As hoped,

8232-473: The way to L 2 and for station keeping  – maintaining the correct position in the halo orbit. Eight smaller thrusters are used for attitude control  – the correct pointing of the spacecraft. The engines use hydrazine fuel (159 liters or 42 U.S. gallons at launch) and dinitrogen tetroxide as oxidizer (79.5 liters or 21.0 U.S. gallons at launch). Webb is not intended to be serviced in space. A crewed mission to repair or upgrade

8330-438: The wings to enhance the propulsion provided by its gliding system, which glides forward while moving up and down in the water column by changing its buoyancy. With an emphasis on minimal human oversight, the creation of the Manta Ray represents a significant advancement in unmanned underwater vehicles (UUV) technology. In September 2024, Northrop Grumman won the U.S. Missile Defense Agency (MDA) competition to develop and build

8428-723: The wireless-enabling technology to enable a Wi-Fi access for employees and equipment in the module. In September 2020, Northrop Grumman won a $ 298 million sole-source contract for the Evolved Strategic Satcom program, an anti-jam communications satellite program intended to replace the Advanced Extremely High Frequency (AEHF) satellite program where Northrop Grumman was a subcontractor to Lockheed Martin . In December 2020, Northrop sold its federal IT and mission support business to Veritas Capital for $ 3.4 billion in cash. Veritas placed

8918-441: Was completed on 3 February 2016. The secondary mirror was installed on 3 March 2016. Final construction of the Webb telescope was completed in November 2016, after which extensive testing procedures began. In March 2018, NASA delayed Webb's launch an additional two years to May 2020 after the telescope's sunshield ripped during a practice deployment and the sunshield's cables did not sufficiently tighten. In June 2018, NASA delayed

9016-458: Was designed to carry out long-duration, long-range military missions, including extended loitering on the sea bottom. The development of the Manta Ray posed several technical challenges, including overcoming the corrosive nature of seawater, preventing sea life from interfering with moving components, and operating under conditions where electromagnetic radiation, including sunlight, does not propagate well. The craft uses two four-bladed propellers on

9114-442: Was made to facilitate future servicing missions. These accommodations included precise guidance markers in the form of crosses on the surface of Webb, for use by remote servicing missions, as well as refillable fuel tanks, removable heat protectors, and accessible attachment points.
