At initially, NASA thought the issue was down to a defective memory module that had actually degraded over time from taking in too much cosmic radiation. When the team switched to a backup unit to power the backup payload computer, Hubble came roaring back to life.
This isnt Hubbles very first outage.” I am impressed by the teams dedication and common function over the previous month to return Hubble to service.
Tricky remote assistance.
” This is a minute to celebrate the success of a group genuinely committed to the objective. Through their efforts, Hubble will continue its 32nd year of discovery, and we will continue to gain from the observatorys transformational vision.”.
This isnt Hubbles very first outage. In 2008, its Science Instrument and Command & & Data Handling unit stopped working and a four-person team of astronauts fixed the maker in orbit in 2009. Backup parts because replacement hardware was booted 12 years later on to handle this crisis.
The telescope was launched in 1990, and was created to last 15 years. Over 30 years later on, however, its still toiling away and observing the heavens.
” Hubble is in great hands,” said Kenneth Sembach, director of the Space Telescope Science Institute, which helps conduct Hubble science operations. “The Hubble group has as soon as again shown its resiliency and expertise in addressing the inescapable anomalies that arise from running the worlds most well-known telescope in the cruelty of area.
” I am impressed by the teams dedication and common purpose over the previous month to return Hubble to service. Now that Hubble is as soon as again offering extraordinary views of the universe, I fully expect it will continue to astonish us with a lot more clinical discoveries ahead.” ®.

Initially, NASA thought the issue was down to a defective memory module that had deteriorated over time from soaking up too much cosmic radiation. Making use of an alternative onboard module didnt fix the concern. More analysis suggested the glitch had something to do with an undecided power control unit. When the group switched to a backup unit to power the backup payload computer system, Hubble came roaring back to life.
” The switch required 15 hours of spacecraft commanding from the ground,” said Jim Jeletic, deputy job manager of the Hubble Space Telescope operating at NASAs Goddard Space Center.
” The main computer had to be switched off, and a backup safe mode computer momentarily took control of the spacecraft. Numerous boxes likewise needed to be powered on that were never ever turned on prior to in space, and other hardware needed their user interfaces switched.
Photos The Hubble Space Telescope is back in action doing what it does best– catching spectacular images of deep space– after more than 50 NASA engineers worked hundreds of hours to get the instrument working once again.
After triggering redundant elements within the orbiting observatory on Friday to clear a hardware glitch, the telescope has actually been able to utilize its sensors again. NASA launched 2 images of oddball galaxies Hubble snapped over the weekend: one depicting two galaxies converging each other, and the other showing a large spiral nebula with three arms.
” Im enjoyed see that Hubble has its eye back on deep space, once again capturing the sort of images that have actually intrigued and inspired us for years,” NASA Administrator Bill Nelson said in a declaration.
About a month ago, Hubbles onboard payload computer, which manages its instruments, inexplicably froze, forcing the primary computer system to put the observatorys sensing units into a non-active safe mode. It was feared by some that ol Hubble was a goner after attempts to restore the device failed.
NASA had to collect 30 to 40-year-old documents to examine the hardware lock-up, and engineers were even called out of retirement for guidance. By changing to backup power supply electronic devices in addition to a backup payload computer system, the United States area firm was lastly able to bring Hubble back online.
Now its all systems go and now hopefully the Hubble controllers greatest headache will be handling the backlog of requested observations.
