The Hubble Space Telescope It was turned on again! NASA was able to successfully switch to a backup computer on the observatory on Friday (July 16) after weeks of computer problems.
On June 13 Close Hubble After a computer from the 1980s that handled scientific telescope instruments suffered a malfunction. Now, over a month since Hubble has had problems, that the Hubble team believes caused With the spacecraft’s power control unit (PCU), NASA switched to the backup hardware and was able to restart the range.
With Hubble back online with this backup device, the Hubble team is watching closely to make sure everything is working properly, According to a statement issued by NASA.
“So far so good – so proud of the @NASAHubble team as I’ve had updates all day long. Assuming progress continues, Hubble will be in science later this weekend! Looking forward to that ‘next’ image,” Thomas Zurbuchen, associate director of the Science Mission Directorate at the Science Mission Directorate, tweeted. NASA following the news that Hubble is on the way to recovery.
So good so far – so proud of the @NASAHubble team as I’ve had updates all day. Assuming progress continues, Hubble will be laying the flag later this weekend! Looking forward to that first picture ‘after’.. 🛰🌌 https://t.co/waRN7gX28cJuly 16, 2021
Included in this switch to backup devices, the team has brought the backup PCU online as well as the Backup Command Unit/Science Data Coordinator (CU/SDF), located across from the Science Instrument and Command & Data Handling (SI C&DH) Unit according to the statement. The PCU converts power to SI C&DH while CU/SDF formats and then sends data and commands across the band.
Other parts of hardware Their backups were also swapped to allow the telescope to operate.
After carefully switching to replacement hardware on Hubble, the team turned on the backup range computer, loaded it with flight software and returned Hubble to “normal operating mode,” according to the statement.
In addition to monitoring the band and its “new” devices after this change, the Hubble team also began to restore في science tools From the Safe Mode configuration they entered after the June 13th glitch.
Bringing all scientific instruments back online will take more than a day, according to a NASA statement, because the team has to ensure the instruments are at a constant temperature and able to operate safely. After the telescope’s science instruments exit safe mode, the Hubble team will calibrate them and then return to scientific work, according to the statement.
This is Not the first time That Hubble had technical problems in space, but the telescope that took off on the space shuttle Discovery In 1990, it has not been serviced by astronauts since 2009, with the shuttle program ending just two years later. Despite some technical bumps in the road, like a flaw in its primary mirror that was repaired in 1993, Hubble has consistently captured some of the most stunning views of the universe ever.
