Mars Camera's Worsening Eye Problems

Mr_Foo writes "According to a Nature article, the Mars Reconnaissance Orbiter's HiRISE imager is suffering from a loss of peripheral vision. The problem surfaced less than a month after the orbiter reached Mars. One the camera's four color detectors has completely stopped working, and it is feared that the problems are spreading. Currently seven of the fourteen HiRISE's detectors are sending back corrupted data and although the issue is only creating a 2% loss of signal at this time it is expected to worsen. The lead investigator for the mission is quoted as saying the problem is systemic: 'In the broken detectors, extra peaks and troughs are somehow being introduced, causing... a "ringing" in the signal. "We don't know where the ringing is coming from," [the investigator] says.' Warming the electronics before taking images seems to help the problem. This effect might be one reason why the detectors on the cold periphery of the array were the first to pack up."

Time to try a different ringtone?

Martians, Motorists and MPs IN REVOLT over snoops

[Rockin'Robert]

Not altogether unlike beleaguered motorists upset with proposed satellite monitored toll road charges, with Britain's MPs even getting in on the Anti-Toll Tax act, the Martians are obviously revolting over eyes-in-the-skies spying. Let's hear it for planetary solidatiry over privacy! http://www.dailymail.co.uk/pages/live/articles/new s/news.html?in_article_id=435384&in_page_id=1770 . BTW: If it's not telescope-signal-jamming from Mars, that ringing is the frickin' fone. SOMEBODY ANSWER IT!!!
