Hubble Get Telescope lives: NASA fix gets backup hardware up and running

NASA’s loved Hubble Get Telescope has been facing in truth one of its ideally suited challenges. A technical glitch left it in safe mode for over a month. This week, NASA stated it indirectly tracked down the availability of the issue and tried a brand new fix, and it appears to be like to agree with worked.

“NASA has successfully switched to backup hardware on the Hubble Get Telescope, including powering on the backup payload computer, on July 15,” the plight agency launched on Friday.

The telescope has been in service for over 30 years. The Hubble crew had been taking a examine the payload computer — hardware courting support to the 1980s — because the skill supply of a memory issue. “A chain of multi-day exams, which included makes an try to restart and reconfigure the computer and the backup computer, were no longer worthwhile, but the info gathered from those actions has led the Hubble crew to discover that the that you will mediate of reason slack the issue is within the Energy Control Unit,” NASA stated.

As with the payload computer, the PCU is fragment of Hubble’s Science Instrument Disclose and Data Handling unit. The PCU is accountable for supplying a relentless and popular supply of electrical energy to the computer and its memory. Hubble is supplied with rather quite lots of backup techniques, including a spare PCU.

Since the issue cropped up on June 13, Hubble’s science work has been stalled. The swap to backup hardware could neutral soundless give the telescope a brand new hire on existence. “The Hubble crew is now monitoring the hardware to win determined that the total thing is working successfully,” stated NASA. This may perhaps increasingly be pleased over a day to win the science instruments out of safe mode before popular science operations can resume.  

NASA operates Hubble in partnership with the European Get Agency. “We’re extremely contented to yelp that Hubble is support on-line!” ESA’s Hubble crew tweeted on Friday. “Congratulations to your total crew that worked right by diagram of the clock to win this occur.”

We’re extremely contented to yelp that Hubble is support on-line! Congratulations to your total crew that worked right by diagram of the clock to win this occur. A substantial thanks goes to the NASA GSFC/STScI engineering & science crew. Next up: resuming scientific observations #WelcomeBackHubble

There has been issue for the getting older telescope. Its successor, the indispensable-delayed James Webb Get Telescope, is soundless right here on Earth, waiting for a that you will mediate of slack-2021 inaugurate.

Hubble has weathered many technical system defects in its time, and it’s taking a look enjoy the broken-down telescope will persevere by diagram of this latest one. Keep it up, universe, Hubble is coming support.
