Revisit Sojourner!

I've been really hoping that one day they'll go back to
the original Sojourner site and return that unit to Earth for
analysis by NASA. They could gain valuable information as to what
finally gave on that rover and use it to harden future
rovers.
Sojourner was a great success as it lasted
much longer than expected. Of course the cost of getting that unit
back to Earth would be so high I'm guessing these are just nice
dreams. C'est la vie.

The batteries can only recharge a certain number of times. Furthermore, there is no way of cleaning the solar panels, so they lose their efficiency over time. That's probably what contributed to its death and you're making a big deal out of a piece of crap rover.

I think the problem with this is that it would require something that isn't just on a one-way trip ending in a crash landing on the planet's surface. That would require development of a new type of lander and something capable of carrying the full weight of the old lander.
I doubt that NASA has the funds or enough desire to go through all this to recover the craft.

Wild-ass guess, but the wiper mechanism would probably get jammed by dust just about the time if could be useful in cleaning off the solar cells.
Seriously, even the scientists on the project wanted an RTG in the thing. They could have driven it around for *years* if they had. Instead, they got solar panels which (due to dust) have an expected lifetime of about 1/2 a year. Stupid environmentalism...

If they'd used an SRG or RTG they wouldn't have those problems. Solar cells? Bah. Waste of weight.
True, but dust and grit would eventually gum up most of the instruments and make wheels stick. The Viking landers didn't do much "moving" science after their first few months (after scooping soil, etc.) They mostly just tracked weather and looked around every now and then.
Making moving parts and instruments dust-resistant and/or cleanable would probably greatly add to the cost I would expect. In other words, power is only half the problem.
Further it costs something like 3 million USD a day to operate rovers (personell, communications, etc.) Thus, extended durations eat money in other ways.
And, it might be better science to have multiple short-distant rovers exploring a variety of marsographically[1] separated areas rather than one to two long-distance rovers. In other words, spend the money on quantity instead of duration.
And, "nuke" power cells are not politically popular due to possible launch crash risks.

Sheesh - the JPL guys ought to talk to some desert racers sometime. They deal with more dust in the course of a Baja 500 than most of us do in an entire lifetime.
Anyway, some simple low-risk ideas:
* A small air blower jet to blow the dust off. After all, there is an atmosphere (albeit a thin Martian one) to work with.
* Tilt the panels and give them a gentle shake to get most of the dust off.
* Use an electrostatic coating to keep the fine dust from sticking.
As far as the batteries, couldn't they be deep-cycled to reduce their memory?

The odds that one would burst are about as close to zero as they get. The RTG itself is sealed inside a "black box" type of shielding. The stuff is strong enough to survive reentry from orbit! An explosion of the rocket wouldn't even phase it (as past launch failures have shown).
...end up polluting a populated area.
Actually, that's why NASA launches over the ocean. If something does fail, it falls into an unpopulated area (i.e. miles of water).

Since the rover arrived with it's panels folded could it just fold and unfold them again to shake some of it off?
It seems such a pity for the mission to end for such a mundane reason since I presume it would otherwise continue until the batteries failed or physical wear/damage destroyed some key component.
Solutions for other missions spring to mind, perhaps: - blowing the dust away with a small directed jet of compressed air. - A small fan or brush on a simple arm. - Speciali(s|z)ed tilt/shake schemes (as above). - Raise the panels up on a windy day (without blowing over). - Layers of protective film that can be peeled away.

Uh... to gain insight on how we can live on other planets. Life on earth is doomed, but it just won't happen (sun expanding) for a long long time. Take into account the chance of life extinguishing asteriods hitting earth, and I'd think that people would want to ensure the survivability of the species.
Face it, the earth is fragile and life on it only temporary until we figure out how to live without it.
Not to mention that humans doing experiments on mars GREATLY reduces the latency. How long does a round trip signal take? I could go on and on about why we want humans on mars.
Why, o why must the sky fall when I've learned to fly?
After approximately 25 sols Beagle 2 will go into it's final communication mode SHM1 (Spell Help Mode 1). In this mode it
will shred it's own parachute and lay the pieces out across the martian surface to spell the world "HELP".
Calculations suggest that each letter will be approximately 4-6 pixels across, easily discernable from the Mars Express orbiter.
High winds may hamper this last ditch attempt for Beagle 2 to communicate.
(I'm allowed to laugh, some of my tax money is spread all over the red planet)
Why does this thing have a "backwards looking hazard identification camera"? Are they that confident about finding life on Mars that they expect to be fleeing from it?
