I got bored the other day and made this, and thought I might share it. It's a Mars Sundial, displaying MTC, Ls, Local Solar Mean Time (LSMT), and solar elevation for each of the active surface missions. It's based on the Mars 24 algorithm given here.

To install onto iGoogle, click on "add stuff", and then "add feed or gadget" down in the left-hand corner, and copy the following URL in:

There's also a standalone version here: http://www.public.asu.edu/~sbporter/MarsSundial.html

Enjoy!

I was looking at the sun elevation throughout the day at the Phoenix site & currently it seems to stay at about 25 degrees within a fraction of a degree all around. Is that right? Probably a bug I guess.

Must be - you'd only get that sun-at-the-same-height effect at a pole, or with 90 deg axial tilt.

For a feel of how the sun's path changes for a planet, depending on latitude, time of day and axial tilt, I wrote this some time ago:

Ring Simulator

For Mars, ignore the presence of rings.

For Swedes, don't ignore the Swedish option.
