What a mission! And it seems they might last another martian year! If they can operate the rovers until the batteries are as dead as the one in my cellphone, they will have squeezed every last drop of science out of them I guess. (Even then, the rovers could still carry on; I have read the batteries can be disconnected, running the rover solely on solar power).
Looking forward, I wonder what the next milestone will be. Has any of the rovers left the landing ellipse yet? Keep it coming! |

Next Milestones:
Spirit: Probably, first traverse along one of terraces in order to visit Utreya *Abyyse* , zone with black or dark sand and later to Home Plate, in South of Hill Columbia. Oppy, Visit the rim of Erebus until the Mogollon's rim at the souther most of Erebus very old and almost buried crater and then left here by going toward to next biggest crater and also deeper that Oppy has ever visited. It must probably around 2 km south and west of Erebus. Only one, Oppy is approaching the limit of landing ellipse. Rodolfo |

I already posted image in another thread, but now I think this is the best place for Full-Res version.
This is my tribute to MER team, deepest gratitude to you!

Nice one dilo, nice to have a picture of Spirit on her birthsol. Your "mission primary target" line on the graph confused me at first, I was thinking "surely there was no target of ~70m/day" that was just me being tired and stupid! But it made me think that another way of marking that graph would be a differently shaded box between 0-90 sols and 0 - 600m showing just how far outside the original mission requirment envelope we now are. It seems a shame on a graph with clumulate distance traveled not to show that we're not far off 10 times the mission requirement! Nice work, cheers, James -------------------- |

Good point, james!
I updated the plot, up to now Spirit lasted 7.5 times the primary mission life and covered a distance 9 times longer  I already highlighted in this short article.

Looks good Dilo, exactly what I had in mind - such a small box in the corner!  May it get much smaller before were done.

Yes, it was the third time they played here in Lisbon though. I had only heard about them by the time they came for the second one (about when they released the () album), but all tickets were sold out, friends of mine who did see it were absolutely amazed.
So I had my hopes up for this third time around and it was quite incredible. I love their music, and played live it seems to go even higher, wonderful concert. And there's that slight alien soundscape, you're not totally earthbound when listening to them |

Spirit completes her first Martian trip around the sun
http://www.news.cornell.edu/stories/Nov05/...an.year.lg.html Nov. 23, 2005 By Lauren Gold lg34@cornell.edu The intrepid Mars rover Spirit was excused from attending the Nov. 18 party in her honor. She was busy climbing down from the summit of Columbia Hills and heading toward a new target called Home Plate, while wrapping up her first trip around the sun since landing on Mars in January 2004. But she was present in -- well, spirit. The Cornell contingent of NASA's Mars Exploration Rover mission saluted the rover with a gathering at the Space Sciences Building -- two days before the official moment (7:37 p.m. Sunday, Nov. 20) occurred. "To me this is one of the most significant milestones in this project," said Steve Squyres, the mission's principal investigator and Cornell's Goldwin Smith Professor of Astronomy. "We have gotten to experience Mars in all the seasons of the year. We've seen all of its moods." -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Is there an article somewhere on the forum dedicated to discussing how long MER will last?
Who many cleaning events have there been? Is there a chart of solar cell output levels for either rover? Will solar cell output ever become a problem at this rate? How long will the batteries last? How many cycles have they taken and when is the end of the warranty date for them? What aliments does each rover have as of now? |

Try to digit "batteries" in the Forum search engine.
I found, in particular, following threads that should contains answers to most your questions: http://www.unmannedspaceflight.com/index.p...indpost&p=19462 http://www.unmannedspaceflight.com/index.p...indpost&p=15561 http://www.unmannedspaceflight.com/index.p...indpost&p=23564 -------------------- I always think before posting! - Marco -

QUOTE (exobioquest @ Nov 29 2005, 02:23 PM) What aliments does each rover have as of now? I'd check out the interview Doug did with Steve Squyres back in September for some insights on this. Audio and transcript are available. But it may be helpful to summarize the current ailments in one spot. The ones I know of off the top of my head are: * Spirit: RAT teeth are shot. * Spirit: One of the drive wheels was sticky, but has since fixed itself * Oppy: Right-front steering actuator is stuck * Oppy: A heater is stuck on * Oppy: Mini TES is flaky - stopped working, then started working again * Oppy: MI comm sometimes returns errors - EDD may have cable fraying * Both: Mossbauer source is depleted to ~25% of landing, integrations take longer And there's the current anomaly with Oppy's MI images, but that's not confirmed as an ailment. Please correct/add to the above. EDIT: Added Mossbauer source depletion -------------------- --O'Dave
