It has been a troublesome previous few weeks for NASA’s well-known Hubble House Telescope, however on Saturday, July 17th, engineers introduced that the swap to the backup pc system was profitable, and that Hubble is as soon as once more operational.

“Hubble is an icon, giving us unbelievable perception into the cosmos over the previous three many years,” says NASA Administrator Invoice Nelson in a latest press launch. “I’m happy with the Hubble crew, from present members to Hubble alumni who stepped in to lend their assist and experience.”

The present spherical of issues began on June 13th, when a fault within the payload pc positioned the telescope in protected mode, suspending science operations. Hubble has a totally redundant backup system. One of many preliminary suspects was a degraded reminiscence module, however switching to onboard backups didn’t clear up the problem. Engineers then got here up with a plan to modify over to backup , put in in 2009 on Hubble’s final servicing mission throughout STS-125 house shuttle Atlantis. This swap was reasonably dangerous, because the backup system hadn’t been turned on since set up greater than a decade in the past.

In persevering with investigations, NASA engineers found final week the possible reason for the malfunction: a defective energy management unit. When it’s functioning correctly, the ability management unit ensures a gradual energy provide to the payload pc, however an issue with the unit induced it to inform the pc to stop operations. The backup payload pc incorporates a totally separate energy management unit.

With the swap over profitable, Hubble made the primary new set of observations in additional than a month on Saturday afternoon, after instrument calibration checkouts had been full. Observations missed throughout troubleshooting and restore will likely be rescheduled to a later date.

Launched in 1990, Hubble has been working in house for 31 years. In that point, it has made greater than 1.5 million observations, and astronomers have made use of its knowledge in additional than 18,000 scientific papers. A complete technology of contemporary skilled astronomers have come of age with Hubble. Because it enters its fourth decade of operation, Hubble ought to now overlap with the James Webb House Telescope, set to launch in November.

Hubble is again in enterprise, and the ultimate story of its saga is but to be written.
