David Shiga writes, "NASA's silent Mars Global Surveyor (MGS) spacecraft is likely lost forever. The space agency attempted to take a picture of the 10-year-old spacecraft using the newer Mars Reconnaissance Orbiter, but did not detect it, either because its orbit has shifted since last contact, or because it isn't reflecting enough sunlight to be visible. NASA has now ordered its Opportunity rover to listen from the planet's surface for MGS's radio beacon. If that fails, the agency may call on the European Space Agency's Mars Express spacecraft to join the search. But MGS may already have run out of power and NASA officials are not optimistic about recovering it."

NASA Struggles To Contact Lost Mars Probe 125 comments
David Shiga writes "Just when NASA was about to celebrate the 10th anniversary of the Mars Global Surveyor (MGS) spacecraft, the probe suddenly lost contact with Earth, New Scientist Space reports. NASA last heard from the MGS probe on November 5, two days before the 10th anniversary of its launch from Earth. The MGS team is not sure yet what the problem is, but a micrometeorite could have jolted the spacecraft's main antenna out of alignment with Earth, or it might have a solar array problem and too little power to talk to Earth as a result. If they can't re-establish communication this week, NASA may try to diagnose the problem by taking pictures of MGS with the Mars Reconnaissance Orbiter. The two spacecraft come within about 100 kilometers of each other several times each week."

Software Error Likely Killed MGS Spacecraft 199 comments
Aglassis writes "NASA investigators have determined that a software update performed in June of 2006 may have doomed the 10-year-old spacecraft. Apparently the software error caused the solar arrays to drive against a mechanical stop which then forced the spacecraft into safe mode. Unfortunately, after that the spacecraft's radiator was pointed at the sun which overheated the battery and destroyed it. Contact was lost with the Mars Global Surveyor spacecraft in November 2006. NASA will form an internal review board to determine formally the cause of the loss of the spacecraft and what remedial actions are needed for future missions."

Exactly. People can say what they want about NASA | JPL, but the bottom line is they put up some good stuff much of the time. What really got my eye was how they just 'asked' Opportunity to listen for it. That is, that those things are so dynamic in what they do and can be 'asked' to do simply amazes me.
Who knew years ago when Opportunity (also past expected mission life, right?) was designed that it would be on-the-fly tasked to listen for another spacecraft's signal. That it was designed in this way is a testament to well planned engineering. IMO.

Luckily one of the engineers realised that if Opportunity was to bounce an inverse-polarity tachyon beam through the fifth phase of a quantum singularity, it might be possible to convert Opportunity's deflector dish into a scanning-tunnelling pulse wave detector

Actually, the Mars Global Surveyor finished its mission, and had long outlasted its original mission scope when the failure occurred. While unfortunate, this failure isn't wholly unanticipated as the craft was "out of warranty" as it were.

Mars Global Surveyor was a huge win in Earth's column. The spacecraft returned friggen superb results, for far longer than we expected. We didn't get "some good work out of MGS," we got vast amounts of good work out of it.
God damn, I wish Slashdot quit posting space related stories.

Curious to know (not just nit-picking semantics), I decided to go to the JPL mission page [nasa.gov]. Voyager 1 passed the 100 AU mark this summer, that's about 12 light-hours. Although it's signal is very weak, we can still talk to it a bit. According to this blurb [nasa.gov]

Absolutely. Voyagers 1 and 2 are still doing significant work, since they are so distant and still functioning. They have begun to encounter the outer reaches of the solar system, where the influence of the Sun ends and interstellar space begins. NASA believes they recently crossed the termination shock and may be approaching the Heliopause. More here: http://en.wikipedia.org/wiki/Heliopause [wikipedia.org]
It's going to be a very, very, very long time before another probe gets out as far as the Voyagers are (if Pluto Express lasts that long, at least 20 years). Voyager gets a fairly decent chunk of Deep Space Network tracking time because of the importance of what it is doing.
The oldest satellites still functioning are Pioneers 6,7, and 8, which are all around 40 years old and still ticking. http://en.wikipedia.org/wiki/Pioneer_6,_7,_8_and_

That's the prevalent meme - but the reality is that space based nuclear power has gotten steadily less controversial. The Mars Science Laboratory Rover [nasa.gov] will almost certainly be nuclear powered - and the proposal to do so has drawn nary a peep.

Implicit in your assumption is that a mission is operated solely by NASA civil service employees, which is a handy assumption for your flip answer, but meanwhile, back in the real world, that's not the case. I'll grant that the people who will be affected have some warning, but I guarantee you Griffin and Co. are already planning on where to reallocate the extended mission money if and when they declare MGS dead. That money doesn't all go to NASA facilities. The science operations for the Mars Orbiter Camera goes to a small company [msss.com] and the Thermal Emission Spectrometer money goes to Arizona State's Mars Space Flight Facility [asu.edu], a place I worked for 4 years and personally witnessed several people get laid off in early '06 because of NASA reallocation for the new manned program and to pay for hurricane damages to NASA facilities.
Yeah, I'm sure the people who got laid off worked something out, and the people who will get laid off will work something out, too. You can continue to choose to "call shenanigans" all you want, but you asked a question, I answered, you didn't like the answer and decided to wave it away with flippant handwaving. This has effects on real people and your "rational ignorance" becomes willful ignorance if you choose to continue to deny it.

We've all seen pictures of the top of Mt Everest. Does that mean we should no longer climb mountains? We have seen pictures of the ocean floor. Should we no longer SCUBA dive? By no means! We explore because it is human nature to test our limits, to push the boundaries, to boldly go where no man has gone before.
We have not even seen one tenth of one percent of the Martian surface, yet there "is nothing more to see". Olympus Mons is the largest volcano in the Solar System, three times as tall as Mt Everest, but who cares. There is nothing to see. Tourists flock by the millions each year to take in the Grand Canyon. The Valles Marineris is the deepest canyon system in the Solar System. Five times deeper, and hundreds of times longer, it makes the Grand Canyon look like a tire rut. But who cares. We've seen a few pictures of a couple of Martian rocks, so there's no point in going to the Valles Marineris. Well, Here's [englishriverwebsite.com] a picture of some Earth rocks, and here's [google.com] a link to some maps. So now you don't ever have to leave your house.
As for Mars being lifeless, we do not *know* that there is no life on Mars. Absence of evidence is not evidence of absence. Why, Opportunity could find lichen on a rock tomorrow afternoon.

Same thing. First, verify it's where it's supposed to be. Second, if the resolution is good enough (and they weren't sure it would be) see if it seems to be oriented correctly.
If it's not where it's supposed to be, then there's a partial explanation of why it's not responding -- it's off course -- and also tells them their options are limited to setting it straight again. If it is, but it's oriented incorrectly, then the batteries are not getting recharged and you focus on getting it oriented correctly so it can get power again. If it is present, oriented correctly, and still not responding, then you've got a different set of options.
More information can only help.
