Space Telescope Imaging Spectrograph
The Space Telescope Imaging Spectrograph (STIS) is a
The STIS was installed on Hubble in 1997 during its second servicing mission (
Congratulations, you brought STIS back to life.
— Astronaut J. Grunsfield, 2009[5]
Design
STIS is both a spectrograph and an imaging camera, and is focused on ultraviolet light.[5]
The STIS has three 1024×1024 detector arrays. The first is a charge-coupled device with a 52×52 arc-second field of view, covering the visible and near-infrared spectrum from 200 nm to 1030 nm.
The other two detectors are Multi-Anode Multichannel Arrays, each with a 25×25 arc-second field of view. One is Cs2Te, and covers the near-UV between 160 nm and 310 nm. The other is CsI and covers the far-UV between 115 nm and 170 nm.[6]
Timeline
- February 14, 1997- STIS installed[3][5] (STS-82)
- 2001, Switches to Side-2 electronics after a failure in side-1.[7]
- August 3, 2004- STIS goes offline due to side-2 power-failure[3][5]
- 2009- STIS repaired[5] (STS-125)
- As of 2022[update] Operating on side-2 electronics with all optical and UV channels.[7]
