One martian year coming up in a few hours!

Nov. 19, 12:23:40 PM UTC if my math is correct smile.gif

It's hard to describe what a fantastic achivement this is. So I'll just say:



Let's keep on roving! wink.gif

Stunning. Did anyone, anywhere ever actually predict this? With Oppy at 4 miles and Spirit nearing 3.5 and the power output on Oppy back up to 720W/Hr again it really looks like the only thing that can kill them is a massive dust storm or a sudden component failure! How are they doing with respect to all the other mechanical aches and pains they've both had over the sols so far (sticky wheels, glitchy MI operation)? Aside from Oppy's mysterious occasional reboot, have they all just worked themselves out?

That's a nice birthsol card, dot.dk biggrin.gif

My thanks and best wishes, too, go to Spirit, Oppy and the rover team! wheel.gif wheel.gif wheel.gif

Wonderful birthsol card, dot.dk .

Happy first birthsol, Spirit and Opportunity. May you have many more productive Sols!

--Bill



PS- great sigline, too.

Happy birthsol (or should that be "mars-anniversary" laugh.gif ), Spirit.
And many happy returns!

I'm not sure if I totally agree dot.dk's calculation of the exact timing of the birthsol but the Birthday card is so damn fine that I need to beg his forgiveness for being a nit pick.

Sol 1 started on the Midnight before Spirit's landing.
There are 668.5921 Sols in a Martian tropical year.
It can be argued that the Marsiversary Sol should therefore start on Sol 669. *
However the the exact timing of the passing of 1 Martian year from the start of Sol 1 takes place at 14.21 local Martian time on Spirit Sol 669 due the 0.5921 fractional part.
Spirit landed at 14:26 local time (LST-A) on Sol-1 so the timing of 1 Martian year after that actually occurs at 4:47 on Sol 670.

* Using Earth Dates and Days.
Landing: January 4 2004 at 04:36 UTC.
Martian tropical year (in days) 686.9725.
Add the two and you get 03:56 on November 21 2005 for the actual event.

It's a stunning accomplishment. I was scoffing a while back at someone who enthusiastically believed that at least one of the rovers would make it to Sol 1000, but it seems more likely all the time.

Great calculations. Now can you tell us how many angels can dance on the head of a pin?

Thanks Dan. I just knew I'd get slapped for being a pedant. smile.gif

The answer to your very topical question depends on what sort of dance. It may depend on other parameters too, I'll have to do some research. Questions that spring to mind are: What sort of Angels? Do I have to consider Archangels, Metatrons and Fallen Angels? What sort of pin? Is the head of a pin the blunt or the sharp end? What about ambient temperature since Heaven is a lot hotter than hell?

I just send a short email to Steve Squyres on behalf of all the #space members on irc.freenode.net. I included dot.dk's picture as a birthsol card:

Dear Steve,

We wish you and the entire team a happy birthsol for Spirit. No one dared to dream that the rovers would last this long.
Thank you for sharing a beautiful place called Mars with us. We're looking forward to all the new discoveries the rovers
will make in the future. On to Home Plate and Victoria crater ! That the rovers may last until there are bootprints in the
tracks.


Thanks from all the guys at the #space chat on irc.freenode.net, representing:

I am very happy to celebrate one birthsol of MER-A and soon another party for MER-B.

The mission of MER is incredible for me since it has brought lots of science, discoveries, learning, surprises, speculations, discusions, and funy time about bets of the probable route plan, arriving dates, probably next breakdowns. We had guess correctly to fews (East ridge, Utreya) and failed some guess (route to south to Erebus, sooner breakdown of Oppy).

I think that the MER's mission is the first type of sharing information (fast and *complete* information) that has created a new big international member with diversity of talents and perspectives that make up interesting debates. Hope that MER team has listed us and picked us some good contributions.

Thanks to dot.tk for a nice card.

Rodolfo

What an amazing achevement! (to add to all the other amazing achevements cool.gif ) Who would have thought it, I remember being amazed when the number 250 was mentioned at around sol 90! I would surely have laughed at anybody silly enough to talk about ONE WHOLE MARTIAN YEAR!

Bring on Oppys marsiversary in three weeks, then were off toward the heady realms of Sol 1000, I think I feel feint blink.gif

Amazing days (sols),

James
