The· Hubble Space Telescope The power is turned on again! NASA was able to successfully switch to an observatory backup computer on Friday (July 16) after several weeks of computer problems.
June 13 Hubble has shut down After a glitch hit a payload computer in the 1980s dealing with telescope scientific instruments. It’s been over a month since Hubble hit the problem, I think it was caused by the Hubble team The spacecraft’s Power Control Unit (PCU) allowed NASA to switch back to backup hardware and turn the scope back on.
Now that Hubble is back online with this backup hardware, the Hubble team is closely monitoring to make sure everything is working properly. According to a NASA statement..
“So far, I’m so proud of the @NASAHubble team that I’ve received updates all day long. Given continued progress, Hubble will be in science mode later this weekend. The first” after ” I’m looking forward to the photos. Thomas Zurbuchen, NASA’s Deputy Director of Science Missions, tweeted following the news that Hubble is on the way to recovery.
Very good so far-I’m very proud of the @ NASAHubble team as I received updates all day long. Hubble will be in science mode later this weekend, given continued progress! I’m looking forward to the first “after” photo. 🛰🌌 https: //t.co/waRN7gX28cJuly 16, 2021
The team involved in this switch to backup hardware brings the backup PCU and the backup command unit / science data formatter (CU / SDF) on the other side of Science Instrument and Command & Data Processing (SI C & DH) online. did. ) Unit, according to the statement. The PCU transfers power to SI C & DH and sends data and commands throughout the scope while the CU / SDF is formatting.
Other hardware It has also been replaced with a backup version so that the telescope can work.
According to the statement, after carefully switching to Hubble’s alternative hardware, the team turned on the scope’s backup payload computer, loaded the flight software, and returned Hubble to “normal operating mode.”
In addition to monitoring this modified scope and its “new” hardware, the Hubble team has also begun to recover Hubble. Scientific instruments From the “safe mode” configuration entered following the June 13 glitch.
According to a NASA statement, it will take more than a day to bring all scientific equipment back online. This is because the team needs to ensure that the equipment is at a stable temperature and can be safely run. According to the statement, after the telescope’s scientific instruments are out of safe mode, the Hubble team will calibrate them before returning to scientific work.
this is Not the first time Hubble had technical problems in space, but a telescope launched on the Space Shuttle Discovery In 1990, it had not been serviced by astronauts since 2009, and the shuttle program ended only two years later. Despite some technical problems with the road, such as the defect in the primary mirror fixed in 1993, Hubble is one of the most breathtaking cosmic views ever I have consistently grasped this.
