Interesting... the MERs are about 200 sols from individually equaling the time the Viking 2 lander remained operational, and the total number of sols for both rovers is about 200 sols short of the time the Viking 1 lander was operational.
In about 700 sols or so, if the rovers last that long, they will have equaled the total operational time of both Viking landers. Pretty durned impressive for solar-powered wheeled vehicles... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

After all the extensions - it's more like $900m I think.

After all the extensions - it's more like $900m I think. Doug OK Doug! So, assuming $900m, on March 15th, the price per sol will be exactly $400.000 as total sol will get to 2250. Here are other stats about how long it took to take 25k pictures from the begining of the mission. I miss the date of the first 25k's and assumed it was linear. If somebody know the date, I'll appreciate. Also number of pictures per sol were we can see summer-winter variations. It's an excel file : Stat_rovers_march_07.xls ( 17K ) Number of downloads: 1623 -------------------- |

Thanks for the update on image statistics, Climber (about Excel file, pls could you better explain the meaning of the plots? what do we see on horizontal axis?).
Now is time to update also my odometry statistics (same scale): -------------------- I always think before posting! - Marco -

Getting close to yet more milestones!
If my excel file is working as it should work, I calculated that, tomorrow, june 16th we'll have accumulated 2500 Earth days on Mars while 2500 Sols will be on July 20th which could be more or less when Spirit will have shot 100.000 pictures. On june 18th, the difference of minutes between Earth and Mars since Spirit landing will be 50.000 (nearly 35 days). More? OK : since end of May, the total cumulated distance is over 18 kms, i.e. 30 times what has been scheduled. -------------------- |

Yep, not that far!
September 29th for Spirit and October 9th for Oppy Regarding the difference between sols and days :we have a 10 Million $ positive difference if we calculate the cost (per sol or day) in Earth days... which seams fair to me since, if we use "external references" it could be VERY expensive to land on Venus and very cheap on Jupiter! -------------------- |

If only we could get humans to Mars for only $400,000 per day! What a bargain, especially in light of a weeklong trip to LEO costing the tourists $20,000,000.

Spirit just reached Sol1400, which is the limit for my last odometry plot, so enjoy this last update with old scale...
I guess Spirit figure will not change very much in the last months . Hope about Oppy restart, which is full of energy! Another update for the number of pictures sent back from both rovers, the average was exactly 100 pics/day in the last 9 months (higher than previous year): -------------------- I always think before posting! - Marco -

OK Doug! So, assuming $900m, on March 15th, the price per sol will be exactly $400.000 as total sol will get to 2250. "[T]he number that most haunted me and Pete ... was the one you got if you took the cost of the mission and divided it by the number of sols we expected to operate on the surface. It came to about $4 million a sol. ... Whatever we built, and whatever we managed to do with it, the result was going to have to be worth at least that much." Steve Squyres, Roving Mars, p. 103.

In truth the operating costs have climbed as well. As I recall the $900 million was as of launch time including normal mission support. To get a true figure we need to add up the costs of all the mission extensions and also the DSN time, if that is not part of those extended mission costs.

$850m was that figure - I just added the $50m as an estimate of the extensions to make $900m

Well however we slice it, they've been a great bargain.

Talking about MER statistics, anyone know where to find a high resolution version of this MER 1000 sols logo?
