Hubble Space Telescope delivers first images since shutdown

NASA’s Hubble House Telescope (HST) has delivered its first photos for the reason that telescope’s payload laptop all of a sudden halted on June 13. 

The images present a galaxy with what the company calls “prolonged spiral arms” and mentioned in a launch is the primary high-resolution have a look at a pair of colliding galaxies. 

The pictures have been taken by a program spearheaded by the College of Washington’s Julianne Dalcanton.

Different potential targets for this system included globular star clusters and aurorae on Jupiter.

Science observations restarted on July 17, after the telescope’s essential laptop didn’t obtain a sign from the payload laptop and subsequently positioned Hubble’s science devices into secure mode.

NASA’s mission analysts, working from the Greenbelt, Maryland, Goddard House Flight Heart mission management along with remotely and engineers labored collectively to investigate the problem and decide its trigger.

The HST has been in orbit roughly 340 miles above Earth for greater than 30 years. The telescope was constructed within the Eighties and NASA mentioned that Hubble alumni had returned to help within the restoration effort.

The staff seemed over 40-year-old paperwork, hoping to diagnose the issue shortly. 

Whereas inspecting the potential of a degrading reminiscence module, NASA switched to backup modules. 

Then, the staff turned on Hubble’s backup payload laptop for the primary time in area. Each duties didn’t resolve the problem. 

Subsequent, different {hardware} – just like the Command Unit/Science Knowledge Formatter and the Energy Management Unit – and switching to backups took 15 hours of spacecraft commanding.

The primary laptop was turned off and a “backup secure mode laptop” briefly took over the spacecraft, a number of containers needed to be powered for the primary time and {hardware} wanted interfaces switched,

Greater than 50 folks labored on the swap to backup {hardware}, testing procedures on a high-fidelity simulator and holding a proper evaluation of the proposed plan.

The staff additionally analyzed information from earlier testing and recognized the Energy Management Unit because the potential supply of their worries. 

Making the swap to the backup aspect of the Science Instrument and Command & Knowledge Dealing with unit and backup Energy Management Unit, NASA was profitable on July 15 at 11:30 p.m. ET.

“I’m thrilled to see that Hubble has its eye again on the universe, as soon as once more capturing the type of photos which have intrigued and impressed us for many years,” NASA Administrator Invoice Nelson mentioned. “It is a second to have a good time the success of a staff actually devoted to the mission. By their efforts, Hubble will proceed its thirty second yr of discovery and we’ll proceed to be taught from the observatory’s transformational imaginative and prescient.”

The HST has taken greater than 1.5 million observations of the universe in its lifetime, contributing to among the most vital discoveries of the cosmos.

Most observations missed whereas science operations have been down might be rescheduled.
