Last week, the Hubble Telescope had to pause science operations after it entered it safe mode due to a gyroscope issue.
It looks like the telescope will resume operations tomorrow. However, NASA is still running tests, to gain insight on why the gyro malfunctioned. Normally, the the telescope has three functioning gyros.
However, NASA has determined that the Hubble Telescope can be reconfigured to operate with only one gyroscope, if needed. During the final space servicing mission in 2009, NASA installed six new gyros. As of now, three of them remain operational, including the one that is experiencing issues.
The telescope is still making amazing discoveries, such as breathtaking images of galaxies far far away.
