NASA struggles to fix a Hubble Space Telescope computer glitch

 


The Hubble Space Telescope has been showing its age for a while, but a new problem is proving to be especially frustrating. As the AP reports, NASA has spent nearly a week (as of this writing) trying to fix a glitch in Hubble's payload computer. The system broke down on June 13th, and the operations team had no success either restarting the computer on the 14th or switching to a backup memory module. The agency also failed in repeated attempts with both modules on the evening of June 17th.


The Hubble Space Telescope has been showing it's anything but some time, yet another issue is ending up being particularly baffling. As the AP reports, NASA has gone through almost seven days (as of this composition) attempting to fix a glitch in Hubble's payload PC. The framework separated on June thirteenth, and the activities group had no achievement either restarting the PC on the fourteenth or changing to a reinforcement memory module. The agency likewise fizzled in rehashed endeavors with the two modules on the evening of June seventeenth. 


The telescope and its logical instruments are still "healthy," the organization said, albeit the administrators put the instruments in an experimental mode as a safety measure. 


This isn't the primary glitch this year. NASA went through days restoring Hubble in March following a product blunder in the principal flight PC. It additionally found that the Wide Field Camera 3's voltage levels had dropped throughout the long term, to where group members expected to diminish those levels to forestall future issues. 


Similarly, as with that camera, age may assume a part in this most recent glitch. Hubble's payload framework utilizes a 1980s-period NASA Standard Spacecraft Computer-1 (NSSC-1) that incorporates two PCs and four 64K CMOS memory modules. Just a single PC and memory module is being used at some random time, however that probably won't make any difference much if more than one part is coming up short. In that light, the James Webb Space Telescope can't come soon enough — while it was at that point charged as a replacement to Hubble, it very well might be the lone choice if the more seasoned machine continues to fall flat with this sort of recurrence.
