On Asteroid Day it was mentioned that the Hubble Telescope had been reported down.
As of yesterday, it is back in action!
These images confirm Hubble's return to its mission, capturing galaxy MADORE2115-273 on the left, and ARP-MADORE0002-503, an unusual spiral galaxy with three arms.
On June 13, Hubble's payload computer, which controls and coordinates the science instruments onboard, stopped working. When the main computer failed to receive a signal, it shut down into safe mode.
One thing to remember is the Hubble was built in the 1980's, so when the team on the ground had to figure out what was wrong with it, they had to look back on previous technology and the knowledge collected from the staff over the years. Retired alumni did come in to assist, including those who had helped build it.
"That's one of the benefits of a program that's been running for over 30 years: the incredible amount of experience and expertise," says Nzinga Tull, the Hubble Systems Anomaly response manager.
Once the issue was determined, the team took two weeks planning and testing every step of the process required to switch on the backup modules for the Command Unit/Science Data Formatter and the Power Control Unit. On July 15, they hit the switch and on July 17, the telescope began taking data again.
