Mars Rover longevity again limited by dust build-up

All these "Close Encounters" type missions, and in all this time, when was the last time we had a rover roam the Moon? That's a place whose resources could actually help us on Earth-- solve our energy problems and all that. Nonsense. If you are after resources you don't go down another gravity well. You'd be much better off exploiting NEOs, especially the Ni-Fe ones. And it would be the ideal jumping board to the rest of the Solar System, if we were able to build and launch rockets from up there. Nonsense again. Assembling inter-planetary ships in free-fall makes a lot more sense than at the bottom of a gravity well. ("Aluminum, silicon, oxygen, low gravity and lots of solar ener- gy to be had..." *That's* music to my ears! Lets talk about exploiting NEOs then. I am all for it. Same with solar power satellites. And space based, solar powered antimatter factories. What's the deal with Mars if we haven't even built a base on the Moon yet? What would a base on the Moon achieve? About the only thing I can think of is to learn how to build a base on Mars. And as you rightly ask "what's the deal?" The answer might be "tourism", but probably not much else. Why do I get the feeling space exploration is funded by people who get their idea of what's important from the head- lines of the National Enquirer? Hmm, maybe space exploration *is* funded by people who get their idea of what's important from the headlines of the National Enquirer? What's the deal with trying to find life out there? Big deal or not, I am not *that* much focused on life on Mars. My comment reflects more of a resentment that the science package on the current rovers will not produce science commensurate with the expense. All we'll get in the end is another IMAX movie and some more evidence (probably still inconclusive) of past water. IMHO, that isn't ambitious enough for 800M$. I mean, it still doesn't mean that *we* could live there, and that's all that counts! Humans now have the ability to live nearly anywhere thanks to our technology. The only thing missing at this stage is the will to do this on a large scale. AFAICS, about the only good reason to build bases on the Moon and on Mars would be if it is done with the long term intention of creating self-sufficient human colonies. And why would we want to do that? -- As a contingency against a doomsday event I suggest. -- Manfred Bartz --------------------------------------------------------------------- "Earth is the cradle of the mind, but one cannot remain in the cradle forever." -- Konstantin Tsiolkovsky, Russian space pioneer |

Um, much as I hate to quibble with these pearls of wisdom... ;-) -- -Andrew Gray |

I wrote (twice!):
Sojourner was still working fine when we last heard from it. When Mars is actually unknown. (Probably not much longer than MP, though.) Looks like something in the sci.space.science moderating machinery is stripping out body lines that happen to begin with "Path". Tsk tsk. The full text of that posting was: Sojourner was still working fine when we last heard from it. When Mars Pathfinder died, we couldn't talk to it any more. How long it lasted is actually unknown. (Probably not much longer than MP, though.) -- MOST launched 30 June; science observations running | Henry Spencer since Oct; first surprises seen; papers pending. | |

So what, even if they were??) I'm not aware that we've run low on Al, Si or O2 just yet. There's also a bit of solar energy available in this half of the world. If you really want to go into space to get it, go to earth orbit, no need to go to the moon (much longer power cord!). Ken What's the deal with Mars if we haven't even built a base on the Moon yet?

Yeah! All these "Close Encounters" type missions, and in all
this time, when was the last time we had a rover roam the Moon? That's a place whose resources could actually help us on Earth-- solve our energy problems and all that. How, is there something that we dont have on Earth already? |

Awk script was intended to stop parsing after the header ended, and didn't. According to RCS, that bug had been there for 9 years and 7 months...

Ever blast a PC fan with a can of "air"? Dust blows off everywhere. It would work, even with a moderately weak compressor. I was thinking along the lines of a thin, transparent plastic cover(s) with "memory" of being tightly rolled. Blow the catch holding the cover down and it rolls back to remove all the accumulated dust. Not sure if it would survive the journey, however. Seems like a nuke-powered rover can be made self-heating, so why the concern over cold? -- Bob |
