NASA agency Hubble Space Telescope (HST) It provides its first images since the telescope’s computer payload abruptly stopped on June 13.

The photos were taken by a program led by Julian Dalcanton of the University of Washington.
Other possible targets The program includes globular star clusters and auroras on Jupiter.
Flag Note It restarted on July 17, after the telescope’s main computer failed to receive a signal from the payload computer and then put the Hubble Science Instrument into safe mode.
NASA mission analyst, working from Greenbelt, Maryland, Goddard Space Flight Center mission control center and remote, and engineers work together to analyze the problem and determine its cause.
HST is in orbit about 340 miles above it Soil For more than 30 years. The telescope was built in the 1980s and NASA says Hubble alumni are back to help with recovery efforts.
The team looked at more than 40 years of paper, hoping to quickly diagnose the problem.

When checking the capabilities of degraded memory modules, NASA turned to spare modules.
Next, the team turned on the Hubble telescope’s backup payload computer for the first time in space. Both tasks failed to resolve the issue.
Then, looking at other hardware — like the data science command/coordinator module and power control unit — and switching to backup took 15 hours piloting the spacecraft.

The main computer is turned off and the “safe mode backup computer” temporarily takes over the spacecraft, some boxes must be run for the first time and the necessary hardware interfaces are exchanged,
More than 50 people working to switch to backup device, testing procedure on a HD Simulation and a formal review of the proposed plan.
The team also analyzed data from previous tests and identified the ECU as the source of their concern.

By switching to the standby side of the Science Instruments module, command and data processing module, and backup power control module, NASA made it July 15 at 11:30 p.m. ET.
“I’m delighted to see that Hubble has revisited the universe, once again capturing the kinds of images that have intrigued and inspired us for decades.” NASA Administrator Bill Nelson She says. “This is a moment to celebrate the success of a team who are truly dedicated to that mission. Through their efforts, Hubble will continue its 32nd year of discovery, and we will continue to learn from the observatory’s transformative vision.”
HST took over 1.5 million observations of the universe during its lifetime, contributing to the vast majority of . pengamatan observations Important discoveries in the universe.
Most observations lost during scientific downtime will be rescheduled.
