Hubble Space Telescope delivers first photos since shutdown

Must read

NASA’s Hubble Space Telescope (HST) has delivered its first photos for the reason that telescope’s payload pc abruptly halted on June 13. 

The footage present a galaxy with what the company calls “extended spiral arms” and stated in a launch is the primary high-resolution take a look at a pair of colliding galaxies. 

The images had been taken by a program spearheaded by the University of Washington’s Julianne Dalcanton.

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

Science observations restarted on July 17, after the telescope’s fundamental pc did not obtain a sign from the payload pc and subsequently positioned Hubble’s science devices into secure mode.

NASA’s mission analysts, working from the Greenbelt, Maryland, Goddard Space Flight Center mission management along with remotely and engineers labored collectively to research the difficulty 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 Nineteen Eighties and NASA stated that Hubble alumni had returned to help within the restoration effort.

The group seemed over 40-year-old paperwork, hoping to diagnose the issue rapidly. 

While analyzing the potential of a degrading reminiscence module, NASA switched to backup modules. 

Then, the group turned on Hubble’s backup payload pc for the primary time in house. Both duties did not resolve the difficulty. 

Next, taking a look at different {hardware} – just like the Command Unit/Science Data Formatter and the Power Control Unit – and switching to backups took 15 hours of spacecraft commanding.

The fundamental pc was turned off and a “backup safe mode computer” quickly took over the spacecraft, a number of packing containers needed to be powered for the primary time and {hardware} wanted interfaces switched,

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

The group additionally analyzed knowledge from earlier testing and recognized the Power Control Unit because the potential supply of their worries. 

Making the change to the backup facet of the Science Instrument and Command & Data Handling unit and backup Power Control Unit, NASA was profitable on July 15 at 11:30 p.m. ET.

“I’m thrilled to see that Hubble has its eye back on the universe, once again capturing the kind of images that have intrigued and inspired us for decades,” NASA Administrator Bill Nelson stated. “This is a moment to celebrate the success of a team truly dedicated to the mission. Through their efforts, Hubble will continue its 32nd year of discovery and we will continue to learn from the observatory’s transformational vision.”

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

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