Near Infrared Camera And Multi-Object Spectrometer
The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) is a scientific instrument for infrared astronomy, installed on the Hubble Space Telescope (HST), operating from 1997 to 1999, and from 2002 to 2008. Images produced by NICMOS contain data from the near-infrared part of the light spectrum. NICMOS was conceived and designed by the NICMOS Instrument Definition Team centered at Steward Observatory, University of Arizona, USA. NICMOS is an imager and spectrometer built by Ball Aerospace & Technologies Corp. that allows the HST to observe infrared light, with wavelengths between 0.8 and 2.4 micrometers, providing imaging and slitless spectrophotometric capabilities. NICMOS contains three near-infrared detectors in three optical channels providing high (~ 0.1 arcsecond) resolution, coronagraphic and polarimetric imaging, and slitless spectroscopy in 11-, 19-, and 52-arcsecond square fields of view. Each optical channel contains a 256×256 pixel photodiode array of mercury ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Telescope Imaging Spectrograph
The Space Telescope Imaging Spectrograph (STIS) is a spectrograph, also with a camera mode, installed on the Hubble Space Telescope. Aerospace engineer Bruce Woodgate of the Goddard Space Flight Center was the principal investigator and creator of the STIS. It operated continuously from 1997 until a power supply failure in August 2004. After repairs, it began operating again in 2009. The spectrograph has made many important observations, including the first spectrum of the atmosphere of an extrasolar planet, HD 209458b. The STIS was installed on Hubble in 1997 during its second servicing mission (STS-82) by Mark Lee and Steven Smith, replacing the High Resolution Spectrograph and the Faint Object Spectrograph. It was designed to operate for five years. On August 3, 2004, an electronic failure rendered STIS inoperable, ending its use 2 years beyond its predicted lifespan. In order to bring it back to operational status, the instrument was repaired by space shuttle astr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-109
STS-109 (SM3B) was a Space Shuttle mission that launched from the Kennedy Space Center on 1 March 2002. It was the 108th mission of the Space Shuttle program, the 27th flight of the orbiter '' Columbia'' and the fourth servicing of the Hubble Space Telescope. It was also the last successful mission of the orbiter ''Columbia'' before the ill-fated STS-107 mission, which culminated in the ''Columbia'' disaster. The Hubble Space Telescope (HST) was placed in orbit during mission STS-31 on 25 April 1990. Initially designed to operate for 15 years, plans for periodic service and refurbishment were incorporated into its mission from the start. After the successful completion of the second planned service mission (SM2) by the crew of STS-82 in February 1997, three of the telescope's six gyroscopes failed. NASA decided to split the third planned service mission into two parts, SM3A and SM3B. A fifth and final servicing mission, STS-125 (SM4) launched on 11 May 2009. The work per ...

Space Shuttle Discovery
Space Shuttle ''Discovery'' ( Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, aggregating more spaceflights than any other spacecraft to date. The Space Shuttle launch vehicle has three main components: the Space Shuttle orbiter, a single-use central fuel tank, and two reusable solid rocket boosters. Nearly 25,000 heat-resistant tiles cover the orbiter to protect it from high temperatures on re-entry. ''Discovery'' became the third operational orbiter to enter service, preceded by '' Columbia'' and '' Challenger''. It embarked on its final mission, STS-133, on February 24, 2011, and touched down for the last time at Kennedy Space Center on March 9, having spent a cumulative total of nearly a full year in space. ''Discovery'' performed both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-81
STS-81 was a January 1997 Space Shuttle ''Atlantis'' mission to the Mir space station. Crew Mission highlights STS-81 was the fifth of nine planned missions to Mir and the second one involving an exchange of U.S. astronauts. Astronaut John Blaha, who had been on Mir since 19 September 1996, was replaced by astronaut Jerry Linenger. Linenger spent more than four months on Mir. He returned to Earth on Space Shuttle Mission STS-84. ''Atlantis'' carried the SPACEHAB double module providing additional middeck locker space for secondary experiments. During the five days of docked operations with Mir, the crews transferred water and supplies from one spacecraft to the other. A spacewalk by Linenger and one of his Russian cosmonaut crewmates occurred after the departure of ''Atlantis''. The STS-81 mission included several experiments in the fields of advanced technology, Earth sciences, fundamental biology, human life sciences, microgravity, and space sciences. It was hoped that d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubble Space Telescope
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goddard High Resolution Spectrograph
The Goddard High Resolution Spectrograph (GHRS or HRS) was an ultraviolet spectrograph installed on the Hubble Space Telescope during its original construction, and it was launched into space as part of that space telescope aboard the Space Shuttle '' Discovery'' on April 24, 1990 ( STS-31). The instrument is named after 20th century rocket pioneer Robert H. Goddard. One of the results was the discovery of tenuous atmosphere for Jupiter's moon Europa in 1995. The gas was determined to be mostly of molecular oxygen (O2). The surface pressure of Europa's atmosphere is 0.1 μPa, or 10−12 times that of the Earth. An example GHRS use was to observe the local interstellar medium in the direction towards Capella. The Goddard High Resolution Spectrograph was removed from the Hubble Space Telescope during the February, 1997, Space Shuttle ''Discovery'' mission STS-82 (also called SM-2 for Servicing Mission 2). It, and the Faint Object Spectrograph, were replaced by two new ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-103
STS-103 was a Hubble Space Telescope servicing mission by Space Shuttle ''Discovery''. The mission launched from Kennedy Space Center, Florida, on 19 December 1999 and returned on 27 December 1999. It was also the last Shuttle mission of the 1990s, and the only mission to span through Christmas.

STS-83
STS-83 was a NASA Space Shuttle mission flown by ''Columbia''. It was a science research mission that achieved orbit successfully, but the planned duration was a failure due to a technical problem with a fuel cell that resulted in the abort of the 15 day duration. ''Columbia'' returned to Earth just shy of four days. The mission was re-flown as STS-94 with the same crew later that year. Crew Mission highlights This mission was originally launched on 4 April 1997, and was intended to be on orbit for 15 days, 16 hours. The mission was cut short due to a problem with Fuel Cell #2 and it landed on 8 April, after 3 days 23 hours. NASA decided to fly the mission again as STS-94, which launched 1 July 1997. The primary payload on STS-83 was the Microgravity Science Laboratory (MSL). MSL was a collection of microgravity experiments housed inside a European Spacelab Long Module (LM). It built on the cooperative and scientific foundation of the International Microgravity Laboratory miss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faint Object Spectrograph
The Faint Object Spectrograph (FOS) was a spectrograph installed on the Hubble Space Telescope. It was replaced by the Space Telescope Imaging Spectrograph in 1997, and is now on display in the National Air and Space Museum in Washington DC. FOS facts *Instrument type: Spectrograph *Wavelength range: 115 to 850 nm A technical description of the construction and operation of the FOS can be found in NASA technical report CP-2244., page 55. A 40 MB PDF file. The instrument used two digicon detectors, 'blue' and 'red', and had a spectral resolution of about 1300 over the 115 nm to 850 nm range. It had a number of apertures of varying size, but the aberration of the HST mirror meant that, until COSTAR was installed, the smallest apertures suffered very serious loss of light; even the largest 4.3-arcsecond aperture collected only 70% of the light from a point source. The digico ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extra-vehicular Activity
Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes ''spacewalks'' and lunar or planetary surface exploration (commonly known from 1969 to 1972 as ''moonwalks''). In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVA has been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China. On March 18, 1965, Alexei Leonov became the first human to perform a spacewalk, exiting the Voskhod 2 capsule for 12 minutes and 9 seconds. On July 20, 1969, Neil Armstrong became the first human to perform a moonwalk, outside his lunar lander on Apollo 11 for 2 hours and 31 minutes. On the last three Moon missions, astronauts also performed deep-space EVAs on the return to Earth, to retrieve film cani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-61
STS-61 was the first NASA Hubble Space Telescope servicing mission, and the fifth flight of the Space Shuttle ''Endeavour''. The mission launched on 2 December 1993 from Kennedy Space Center (KSC) in Florida. The mission restored the spaceborne observatory's vision (marred by spherical aberration in its mirror) with the installation of a new main camera and a corrective optics package (COSTAR). This correction occurred more than three and a half years after the Hubble was launched aboard STS-31 in April 1990. The flight also brought instrument upgrades and new solar arrays to the telescope. With its very heavy workload, the STS-61 mission was one of the most complex in the Shuttle's history. It lasted almost 11 days, and crew members made five spacewalks (extravehicular activities (EVAs)), an all-time record; even the re-positioning of Intelsat VI on STS-49 in May 1992 required only four. The flight plan allowed for two additional EVAs, which could have raised the total nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
