It is official; NASA now confirms: The Spirit rover is dying
One more crippling bombshell hit the already beleaguered Mars exploration community when NASA confirmed that the rover's power level has dropped yet again, now down to less than a fraction of 1 percent. Coming close on the heels of the recent Phoenix Lander failure, this news serves to reinforce what we've known all along. The Spirit is collapsing in complete disarray, as fittingly exemplified by a story on Slashdot regarding its power failures.
You don't need to be a Kreskin to predict the Spirit rover's future. The hand writing is on the wall: the Spirit rover faces a bleak future. In fact there won't be any future at all for the Spirit rover because the Spirit rover is dying. Things are looking very bad for the Spirit rover. As many of us are already aware, the Spirit rover continues to lose power. Machine oil flows like a river of blood.
Let's keep to the facts and look at the numbers.
NASA states that there are 89 watt hours of energy. How much energy is required each day? Let's see. There are heaters including one that protects a science instrument, the miniature thermal emission spectrometer, as well as communications equipment. Now NASA has had to switch all these off.
Due to the troubles of metric/imperial conversion and so on, the Beagle Probe crashed and attention was taken over by the Phoenix Lander. Now the Phoenix Lander is also dead, its corpse turned over to yet another rusting hulk.
All major surveys show that the Spirit rover has steadily declined in power. the Spirit rover is very sick and its long term survival prospects are very dim. The Spirit rover continues to decay. Nothing short of a Martians with batteries could save the Spirit rover from its fate at this point in time. For all practical purposes, the Spirit rover is dead.
