Hobbling off, Hubble goes blind (again)

See no evil, Hubble goes blindOur big "eye in the sky" is down with another case of sore eyes. The Hubble Telescope had unexpectedly shut down its most frequently used camera, the Advanced Camera for Surveys (ACS). The engineers are still investigating the problem, and so far, they've only managed to narrow it down to the High Resolution Channel (HRC).


The HRC is just one of the three channels of the ACS. This channel has the highest resolution, and can take detailed shots of planets and other interstellar objects. The other two channels seem to be working fine, and they noticed that ACS detected zero energy from the HRC.

This is why it had shut down. The weird thing is, unlike that of the malfunction back in June, this one is different. Engineers say that the power supply seems to be working perfectly and that it's the HRC's electronic wiring that is faulty.

The Hubble mission managers and engineers remain hopeful, though, and they're aiming to go back on-air by next week. They don't seem to be too worried about the HRC going offline. Since it's only used 10% of the time, it's not the worst case scenario. They'd just have to use the other instruments and channels in the meantime.
