Hubble telescope has broken camera for visible spectrum




Hubble telescope has a non-working camera. It is a camera that is suitable for the visible spectrum: the light that can be observed with the human eye. The other instruments of the telescope still function normally.

The broken camera concerns the Advanced Camera for Surveys, which astronauts installed in 2002 during a maintenance mission. According to NASA , this instrument has not been working since a few days after an error was detected during a normal start-up procedure. It would be a problem where the software is not loaded correctly. NASA technicians have collected diagnostic information and are trying to find the cause and a solution based on this.

NASA emphasizes that the telescope is still functioning normally. The remaining instruments still work ‘nominally’, namely the Wide Field Camera 3, the Cosmic Origins Spectrograph and the Space Telescope Imaging Spectrograph.

The Hubble telescope is a joint project of NASA and ESA and was brought into a low orbit around the earth in 1990. In principle, the intention was that the telescope would be operational for about fifteen years, but that has already been around for thirty years. The last maintenance mission took place in 2009 and had to extend the lifespan by about five years, but this has already taken years to come.

The current non-working Advanced Camera for Surveys also had a problem in 2007, when the power supply of the instrument ceased. This problem was solved during the 2009 maintenance mission. Last year there were already problems with Hubble, after a gyroscope no longer worked .

Incidentally, there were problems with the Hubble telescope immediately after the launch in 1990. At that time no sharp photos could be taken, because the primary mirror had a somewhat incorrectly formed surface at the microscopic level. This problem was remedied by repairs and a corrective element, the Costar . This instrument contains five pairs of corrective mirrors that negate the effect of the primary mirror deviation.
