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.
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 ).
[1] The instrument is named after 20th century rocket pioneer
Robert H. Goddard .
[2]
One of the results was the discovery of tenuous atmosphere for Jupiter's moon
Europa in 1995.
[3] The gas was determined to be mostly of
molecular oxygen (O2 ).
[3]
[4] The surface pressure of Europa's atmosphere is 0.1
μPa , or 10−12 times that of the Earth.
[5]
An example GHRS use was to observe the local
interstellar medium in the direction towards
Capella .
[6]
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 ,
[7] were replaced by two new instruments installed during the mission,
[8] the
Near Infrared Camera and Multi-Object Spectrometer (NICMOS) and the
Space Telescope Imaging Spectrograph .

Instrument details
A technical description of the construction and operation of the GHRS can be found in the GHRS instrument handbook.
