The Hubble Space Telescope is back.
The iconic scale resumed normal operation on Friday, October 26 after a three week hiatus caused by two orientation gyroscopic issues, NASA officials announced an update on Saturday, October 27th.

Hubble’s problem began October 5 when a gyrophel sent the telescope in a safe safe mode. Mission members worked to recruit a backup gyroscope, but had trouble doing it, as the gyro returned divergent readings – especially the saturated rotational speeds that were higher than the actual.
“Last week, the Hubble Operation Team commanded to perform many maneuvers, or swing and switch gyro between different operating modes, which managed to clear what was thought to be blocking the components of the gyro that gave them too high values,” NASA officials said on Saturday update.
Further testing and monitoring showed that the gyro worked normally, so the mission team took Hubble back online.

Hubble has a total of six gyroscopes, three of which must be functional for scope to work with maximum efficiency. Two Hubble gyros had previously checked out, so the October 5 error eliminated the range of error ranges.
But that does not mean that fixgy backupgyro was a matter of life or death for Hubble. The area can still make valuable observations in one or two gyro states, NASA officials said. If the backup continued to abuse, the task would probably have gone to one-gyro mode, with the second functioning backup backup gyroskop.
Hubble, a joint mission by NASA and the European Space Agency, was launched to Earthbreak in April 1990 on board Space Discovery. The original images of the telescope were blurred due to a minor defect in their primary mirror, a problem that space-wielding astronauts were established in December 1993.
The astronauts repaired and further upgraded Hubble to four additional service missions. The last of these, in May 2009, included the replacement of all six gyroscopes.
A gyro problem has also recently launched NASA’s Chandra X-ray Observatory, launched in 1999.
