Hubble Space Telescope Returns to Action After Gyroscope Glitch
By Mike Wall, Space.com Senior Writer | October 29, 2018 07:00am ET
The Hubble Space Telescope is back.
The iconic scope resumed normal operations Friday (Oct. 26) after a three-week hiatus caused by issues with two orientation-maintaining gyroscopes, NASA officials announced in an update Saturday (Oct. 27).
Hubble's first bounce-back science work, which wrapped up early Saturday morning, involved infrared-light observations of the star-forming galaxy DSF2237B-1-IR with the Wide Field Camera 3 instrument, NASA officials added. [The Hubble Space Telescope's Most Amazing Discoveries]
Hubble's troubles began Oct. 5, when a gyro failure sent the telescope into a protective safe mode. Mission team members worked to recruit a backup gyroscope but had trouble doing so, because the gyro returned anomalous readings — specifically, it measured rotation rates that were higher than the actual ones.
