Perhaps a new topic is in order at the very special occasion of 3000 sols for Oppy. Congratulations to everyone on the team for what's become a truly epic mission. And with a whole new destination ahead of her: Tribulation!
The MER filenames clock has now turned to sol 3000, a bit before the jpl site and SPICE: |

So I guess this is as good a time as any to announce that Stu and I have collaborated on a new 'poemster' (poem/poster) to mark this latest milestone in the MER journey.
3000 Martian days (sols)...what an incredible achievement. Huge congratulations goes to the entire MER team of mission planners, scientists, researchers and of course, those amazing Rover drivers. You can find larger versions of the poemster, plus a few desktop wallpaper versions on my blog. Enjoy. GO OPPY! |

And a BIG tip of the hat to Astro0 for the beautiful new banner commemorating the occasion!
GO OPPY!!! -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I absolutely love this poemster!
"Opportunity's heart-flame of exploration still burns bright, The rover that should have died long ago Refuses to go softly into the Martian night." 3000 sols, wow! Just today, I met a fellow who still works at Rocketdyne, was involved in producing some of the components for the MERs and the upcoming MSL. We had a few laughs about how cute it was to have a MER drive over me at a JPL open house, while letting MSL drive over me seems like it'd hurt a lot! If it's okay to blow your horn in this thread, perhaps this is a nice time to mention that I played on a soundtrack with John Lee Hooker and Miles Davis: http://www.youtube.com/watch?v=kNuEsiVAJmE...feature=related -Bradford Ellis = brellis |

At one stage we asked ourselves whether the rovers will last untill MSL arrival. It was more as a joke than anything else. It was a looooong time ago and none of us ever calculated it would be after 3000 sols.
Bravo! -------------------- |

Poemster looks beautiful, Astro0, as does the new banner, fantastic work!
I've a special post up on my "Road to Endeavour" blog now, celebrating Sol 3000, which I hope some of you will find interesting... http://roadtoendeavour.wordpress.com/2012/...e-thousand-sols -------------------- |

Great article Stu and wonderful interviews.
Was that third person still at the bottom of the sea when he wrote that?! Congratulations to you as well on your Road to Endeavour blog. It is a fantastic 'chronicle' of this martian adventure. As an aside, I was speaking with JPL Director, Dr Charles Elachi who was visiting CanberraDSN today. We were looking at our Visitor Centre's fullscale MER replica and I glanced over at the clock to notice it was the exact moment when Opportunity reached Sol3000. I mentioned it to him and he shook his head and he said "I hadn't realised that was today. The change in time zones threw me". "Imagine how jetlagged Opportunity must feel" I replied |

Great achievement, indeed !!!
(where is that emoticon with curtseying face?) Regarding rover's Li-ion betteries, would anybody know how they are performing now after 3000 sols and 9 years of operation? I couldn't find anything more up to date then status after 670 sols in this document - capacity loss in the MER batteries is 5-10% thus far. Thanks |

Congratulations to the whole MER team -- designers, fabricators, testers, operators, planners, managers, etc.! Remarkable to have a rover operating so long with so much capability still remaining. It would be ironic if a photovoltaic-powered craft was able to operate longer on the surface of Mars than a radioisotope-powered one. :-)

Reliability for one ( 2400Whrs/sol rather than 900, then 700, then 300, then camp for winter at 200 etc etc etc ) An MMRTG also produces a lot of spare heat to keep the rover itself warm. |

Here is a little update (26-Jun-2006 ) from the report above: http://trs-new.jpl.nasa.gov/dspace/bitstre...3/1/06-1597.pdf Or you could search the database like this: http://trs-new.jpl.nasa.gov/dspace/simple-...ver+mer+battery -------------------- Need more input ...

Or you could search the database like this: http://trs-new.jpl.nasa.gov/dspace/simple-...ver+mer+battery Thanks a lot, MoreInput, it's very good source of engineering papers. It looks like battery capacity was still around 85-90% after 3 years, which is excellent, but unfortunatelly no info how it looks now in 2012. Anyway, thanks again. |
