Goddard High Resolution Spectrograph
Illustration — Space Shuttle Discovery heads into orbit during its 1990 STS-31 mission with the Hubble Space Telescope and its original instrument suite, including the High Resolution Spectrograph. • Illustration — GHRS being removed during Servicing Mission 2. (1997) 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. One of the results was the discovery of tenuous atmosphere for Jupiter's moon Europa in 1995.

Instrument details
The gas was determined to be mostly of molecular oxygen (O 2). 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 instruments installed during the mission, the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) and the Space Telescope Imaging Spectrograph.
• Instrument type: Ultraviolet spectrograph • Wavelength range: 1150 to 3200 Å (105 to 320 nm) • Resolving power • Low - 2,000 • Medium - 25,000 • High - 80,000 A technical description of the construction and operation of the GHRS can be found in the GHRS instrument handbook.
An astronaut removes the High Resolution Spectrograph in preparation for a new instrument during the second servicing mission in 1997. Hubble’s science instruments are large and complex. The telescope can hold four telephone-booth sized instruments and four piano-sized instruments. The High Resolution Spectrograph was replaced by the Space Telescope Imaging Spectrograph, which has more expansive c

This drawing illustrates the Hubble Space Telescope's (HST's) Goddard High-Resolution Spectrograph (GHRS). The HST's two spectrographs, the GHRS and the Faint Object Spectrograph (FOS), can detect a broader range of wavelengths than is possible from Earth because there is no atmosphere to absorb certain wavelengths. Scientists can determine the chemical composition, temperature, pressure, and turb
