That's an interesting perspective, Deimos. Would you say this culture change is a result of increased experience (and confidence) with Mars rover operations in general, or increased maturation of the players
 , or perhaps a liitle of both?All teasing aside, though, Sojourner was a secondary vehicle with admittedly far less capability then the MERs so its premature loss would not have been the end of the Pathfinder mission, just a degradation. This would probably foster a tendency to take greater risks with it if the potential rewards seemed at all achievable. -------------------- 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.

Update on pictures and Whrs, in occasion of 6th anniversary:
As usual, on the left plot green curve shows cumulative pictures (Spirit only) and red is total (both rovers). Blue dotted is average pics/day from both. Right plot shows energy in whr/sol, decay slope for Spirit is really worring... -------------------- I always think before posting! - Marco -

Spirit is less than one mission duration away from breaking Viking 2 duration of 2245 sols
Fingers crossed. -------------------- |

100% agree. What I was thinking was that if she sleeps at that time and dies before spring come, we'll never know if she made it.
But I'm on the optimistic side too; no doubt she'll make it and rove again. -------------------- |

I trust the Sun will look after Spirit
 Thanks for those intriguing stats Climber... -------------------- 'She drove until the wheels fell off...'

3 milestones rounded up at the end of January 2010!
Oppy reaches 12 miles 27 km total for the Rovers Which is 45 times more than scheduled Also, there are more than 62 days differences between Sols and Days since landing. Except Scott Maxwell , they all must be happy they did synchronise a while ago

Scott Maxwell Tweeted:
"Below ~140W-hr/sol, we're power-negative & start dipping into batteries. Too many sols at that level & we hibernate. " Hang in there, gal... -------------------- |

"Don't bet against Spirit"... <---- good advice, she's a tough one.

QUOTE (Stu @ Feb 23 2010, 08:27 AM)  Below ~140W-hr/sol, we're power-negative & start dipping into batteries. Too many sols at that level & we hibernate. Here we go (139Whr on sol 2203):

@marsroverdriver mentioned that as IIRC, Spirit is down to 133whr as of March 22 (~ sol2210)
Hang in there girl! |

QUOTE (dilo @ Mar 23 2010, 11:24 PM) Here we go (139Whr on sol 2203): This was mentioned in the spirit thread, but probably worth mentioning here. 140Whr is no longer the threshold for hibernation: QUOTE (marsroverdriver) Brilliant uplink team found way to shave Spirit's energy needs; can get by w/120ish now. Might stave off hibernation another couple weeks!

QUOTE (Deimos @ Mar 12 2009, 03:09 AM) Wikipedia knows all. But ... VL1 was successfully commanded (to do the wrong thing) on sol 2252. It landed on sol 0, so that's 2253 sols of operations. The place that messed up the sols also messed up the Earth date (11/19, 1982, not 11/13). Mark, Sorry for replying to such an old post, but as Spirit and Opportunity are now closing in on the VL-1 record I have been trying to understand exactly what the record is. While VL-1 was, as you say, given the faulty commands on sol 2252, as far as I can tell there was no response to that command and of course no subsequent response at all. At the time communications sessions were only being done approximately weekly, so as far as I can tell the last time that anything was actually heard from VL-1 was the previous DSN session back on sol 2245 (the date that most sources give for EOM) I guess the question is: Is the end-of-mission, the day we broke it, or the day we last heard from it?
