The Hubble Space Telescope has shown its old age for a long time, but the recent problem is particularly troubling. The US National Aeronautics and Space Administration (NASA) has been making unsuccessful attempts for a week to fix a malfunctioning telescope’s onboard computer.
The source says the telescope went down on June 13. NASA specialists tried to reboot the on-board computer the next day, but this could not be done. Also, experts were unable to switch to a spare memory module. A repeated attempt to reboot the on-board computer was carried out on June 17, but it did not lead to the desired result. NASA said the telescope and the instruments in its construction are still in “good condition,” although the Hubble has been put into safe mode of operation.
It is worth noting that this is not the first such failure this year. In March, NASA spent several days restoring the Hubble’s functionality, which had been disrupted due to a software error in the main on-board computer. In addition, experts discovered a voltage drop in one of the chambers of the device over the decades spent in space. As with the camera, the current problem is also related to the age of the telescope and the equipment used in its construction.
Recall that the Hubble telescope uses a standard onboard system from the 1980s, which includes two computers and four memory modules. Only one computer and one memory module is used at any one time. Considering that the Hubble has been in outer space for more than 30 years, it may turn out that it will not be possible to return it to a working state.
