End of the Road For NASA's Mars Rover?
An anonymous reader writes "NASA celebrated Mars rover Spirit's bountiful, six-year stint on the red planet on Sunday – way longer than its forecast three-month mission. But it all may soon come to an end, stuck as it is in Martian sand."
As spectacular as some of its failures have been -- like slamming a probe into Mars because one group failed to convert the units the other group was using -- it's important to recognize that NASA is capable of equally spectacular successes. These rovers have done way more than anyone expected and helped us learn a tremendous amount about Mars. We definitely got more than our money's worth on this project, and the scientists and engineers whose hard work made it happen deserve some serious accolades.

I'd just like to take this opportunity to tip my hat to the folks that designed this rover. It was slated for a 180 day mission, and they just finished up day 2,190. That's some pretty high quality engineering that must have gone into this project, especially when you take into account it's on *another planet*, so no tech to fiddle with something that's just a bit off here or there.
No parts, no cleaning, no help at all. To top that off, it's doing all of this on Mars, which isn't really an electronics friendly environment. It crash landed on another planet from a rocket ship and worked 10x longer than it was supposed to.
Well done.
IIRC they put it in "low power mode" last Martian winter and were pleasantly surprised when it survived, booted up, and restarted communications with Earth again when there was enough sunlight available. The trouble is, this year it's stuck at a less-than-ideal angle for collecting sunlight so there may be less of a chance of a springtime startup unless they can adjust the position, which of course takes, well, power. It's a risk either way. Plus, I think it's just locked up a second wheel, leaving it with 4 of 6.
So we'll see. If it can't move again but gets power, its utility as a science platform is going to be severely impacted. Still, it will be able to collect data and pictures of the changing landscape in its immediate vicinity, and it seems to have gotten stuck in an interesting spot, so there will still be useful data coming out of it.
And since the warranty ran out 5+ years ago, I think even a partly functional stationary science platform is pretty darned impressive.
Even after six years, the simple fact that Mankind has working scientific instruments on Mars gives me a geekgasm all over again.

Also, if you're putting a robot on a sand planet, wouldn't it kind of make sense to have some fans to blow off the sand from the solar panels?
Air pressure averages about 1% of Earth's. There simply isn't enough atmosphere to justify a fan or the power it would draw.
I dunno what's with the blame game, it's alone on Mars, something was going to go wrong eventually. If the designers had made an improvement that would alleviate THIS problem, something else would be missing making THAT a problem.
Oh if only someone had thought to turn the radioactive heating units into emergency backup power! (sarcasm) If only someone had thought to install fans to blow the dust off! (previous poster, more sarcasm.)
It is an incredibly well-designed machine; just like with the human body, everything has a cost. Improving one item means less for the rest.
When I toured JPL it was obvious that the people there have an emotional bond with this little animal robot, its gritty determination, it's spirit of exploration.
"wouldn't it kind of make sense to have some fans to blow off the sand from the solar panels?"
It was only expected to go 90 days, and not expected to suffer much dust or winter over.
Another in the long line of 'why didn't they'. As in:
"Why didn't they build these things to last 6 years?" Answer: They weren't expected to.
"Why didn't they think of this or that?" Answer: The mission requirements did not include that.
"Why did they do this or that?" Answer: They exercised their best judgement at the time. So far, so good.
What part of exceeding your expectations by 24 times are you complaining about? Your GF expected a 1.0+ct diamond, and she got a 24-ct one? She complains it's VSS-1? That it's heavy? That it catches on her clothes? That it blinds people on the street?
And does she ask you how much you paid for it, and you end up telling her the truth, you paid for a 1/4 ct brilliant, and wow, 6 years later ya got this...
Again, no complaints about the Rovers. Spectacular performance. And NASA is scouting around for the next robotic mission. Ask some of these guys for ideas, anyone?
deleting the extra space after periods so i can stay relevant, yeah.
These rovers are a very mature design that has worked flawlessly. Build and send a dozen of them.
gigantino.tv - Heavy but weighs nothing.
There's a 1928 Duesenberg that has never had any maintenance whaever, not even an oil change, and it's still working. However, it has a flat tire and can't get to the gas station and it's almost out of gas.
Except it's on Mars.
