Editor’s Notice: This write-up has been current to mirror new data in which Hubble has returned to science functions.
The Hubble Room Telescope has driven on when yet again! NASA was ready to efficiently change to a backup computer system on the observatory on Friday (July 16) next weeks of computer system difficulties.
On June 13, Hubble shut down just after a payload computer system from the 1980s that handles the telescope’s science devices experienced a glitch. Now, above a thirty day period considering that Hubble ran into problems, which the Hubble staff thinks ended up prompted by the spacecraft’s Ability Command Device (PCU), NASA switched to backup components and was able to change the scope again on.
With Hubble again on line with this backup hardware, the Hubble team is holding a shut watch to make certain that every thing performs correctly, in accordance to a statement from NASA.

“So far so fantastic – just so happy of the @NASAHubble staff as I been given the updates all day. Assuming ongoing progress, Hubble will be in science method later on this weekend! Seeking forward to that to start with “immediately after” photograph,” Thomas Zurbuchen, the affiliate administrator for the science mission directorate at NASA tweeted following the news that Hubble was on the road to restoration.
So considerably so great – just so happy of the @NASAHubble group as I gained the updates all day. Assuming ongoing progress, Hubble will be in science method later on this weekend! On the lookout ahead to that 1st “after” photograph.. 🛰🌌 https://t.co/Alert7gX28cJuly 16, 2021
Zurbuchen’s prediction was suitable. This earlier weekend on Saturday (July 17), Hubble’s science instruments returned to operational status and the telescope was able to resume amassing science facts and observing the cosmos.
“Hubble is an icon, giving us outstanding insight into the cosmos about the previous 3 decades,” NASA Administrator Invoice Nelson reported in a assertion pursuing this enjoyable update. “I’m happy of the Hubble workforce, from present members to Hubble alumni who stepped in to lend their assistance and expertise. Thanks to their dedication and considerate function, Hubble will carry on to develop on its 31-year legacy, broadening our horizons with its perspective of the universe.”
Bundled in this swap to backup hardware, the workforce brought the backup PCU online as very well as the backup Command Device/Science Facts Formatter (CU/SDF), which is on the other side of the Science Instrument and Command & Knowledge Dealing with (SI C&DH) device, according to the statement. The PCU diverts energy to the SI C&DH when the CU/SDF formats and then sends facts and instructions through the scope.
Other pieces of hardware were also swapped to their backup versions to make it possible for the telescope to functionality.
Following diligently switching to the different components on Hubble, the group turned on the scope’s backup payload computer, loaded it with flight computer software and returned Hubble to “typical operations method,” in accordance to the assertion.
In addition to monitoring the scope and its “new” components following this change-up, the Hubble crew labored to recuperate Hubble’s science instruments from the “safe and sound manner” configuration that they entered pursuing the June 13 glitch.
Finding all of the science devices again on the internet did, as envisioned, choose much more than a working day, according to the NASA assertion, mainly because the group experienced to ensure that the devices were at a secure temperature and are capable to run properly.
This is not the very first time that Hubble has experienced technical concerns in space, but the telescope, which introduced aboard the space shuttle Discovery in 1990, has not been serviced by astronauts given that 2009, with the shuttle program ending just two yrs later. Even with some specialized bumps in the highway, like a flaw with its most important mirror that was set in 1993, Hubble has continuously captured some of the most amazing sights of the cosmos ever seen.
