One martian year coming up in a few hours!
Nov. 19, 12:23:40 PM UTC if my math is correct It's hard to describe what a fantastic achivement this is. So I'll just say: Let's keep on roving! _||_____O___|__ /////////////////// -------------------- "I want to make as many people as possible feel like they are part of this adventure.

QUOTE (helvick @ Nov 19 2005, 10:16 AM) 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. Happy Marsiversary Spirit |
