NASA will try in the Martian Spring to contact Phoenix

NASA missions on Mars have been used to conduct a wide variety of scientific experiments. Much of the scientific scrutiny from NASA and other space agencies centers on Mars.

NASA launched Mars Phoenix lander in August of 2007 and sent it speeding towards Mars. In May of 2008, the Phoenix touched down and began its mission on the red planet. One of the tasks that Phoenix was sent to Mars to accomplish was to find out if water ice was present in the Martian soil.

Phoenix did find evidence that ice was in the Martian soil and after its three-month mission ended, NASA decided to keep Phoenix working. In November of 2008, NASA officially closed the mission Phoenix was conducting when it lost communications with the lander after it lost power and could no longer sustain itself.

NASA had expected Phoenix to lose power during the harsh Martian winter, though it continued to try to get the rover to respond to commands sent from satellites orbiting Mars to no avail. This week NASA reported that controllers have stopped trying to use the pair of probes orbiting Mars to communicate with Phoenix.

NASA says that Phoenix last communicated with the Mars Odyssey orbiter on November 2. Controllers tried on November 29 to raise Phoenix one final time. The advancing Martian winter is depriving the lander of the solar energy it needs to maintain working power levels.

NASA says that there is a remote chance that Phoenix could survive the -150 degree Martian winter and will try in the Martian springtime to re-establish contact with the lander.

Don't lose hope yet, just like springtime is a time for bears to rise from hibernation, the Phoenix lander might have some juice left to communicate once again. It's so sad that the Martian winter sort of coincides with winter here on some parts of the Earth. But that's good if you look at it in that way. Similar to earth's, so similar.... =)

Errrr... well it was just a 50/50 chance that Mars winter would coincide with either the northern or the southern hemisphere or am I missing something?

RIP Phoenix till you come again...

Send the damn Energizer Bunny to charge that thing up. That way we can continue to research and get rid of those annoying commercials. Win/Win for everyone.

I'd rather like a bunny girl to charge me up

Well, we could always wait for summer hehehe. Or maybe we could use this as a learning experience for our next genration of rovers. Hopefully, all of these "mistakes" could be turned into something positive in the future. Look on the brightside guys, lots of info was gathered then maybe someday we could create the "perferct" rover or whatever it is we're gonna use to gather additonal data

This wasn't a mistake, it was expected.

Don't you think it was designed with those sort of temperatures in mind when they decided to shut it down over the Martian winter, and try to reactivate it in the spring when more solar-energy is available?

I'd guess that the circuitry is kept within a suitable temperature range by being very highly heat insulated, and having a heater to keep the critical circuitry and associated power-supply components within a functional temperature range. That heater will almost certainly receive priority before all other circuits (as they will fail if the heater is shut down instead). Just because the rover is no longer responding doesn't necessarily mean it has no power, it may just be using the limited power it has during the Martian winter to "keep itself alive".

That wasn't the plan. The mission is over. THe mission was designed for 3 months, that's it. everything after that was just extra icing on the cake. Trying to coax extra value out of it. But it was designed for 3 months, and now they're seeing if it'll survive the winter.
