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: http://hosting.gmodules.com/ig/gadgets/fil...MarsSundial.xml There's also a standalone version here: http://www.public.asu.edu/~sbporter/MarsSundial.html Enjoy!

Great work. Here is a better way to link to it so that people don't have to copy and paste (it will bring you to a thumbnail page):

This is very, very cool. I don't suppose you could possibly add sol numbers to it?

Good idea, I'll add that. Just to make sure I'm not crazy, MER started on "Sol 1", but Phoenix was "Sol 0"?
OK, new standalone version here: http://www.public.asu.edu/~sbporter/MarsSundial2.1.html And I tried to update the Google version, but it didn't appear to work; I'll give a little while to see if the database will cycle through... At any rate, here's the direct link to the new version: http://hosting.gmodules.com/ig/gadgets/fil...MarsSundial.xml Simon |

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.

Works fine for me! You're fast. Only thing is on my browser (IE 7 on Win XP), the bottom line of text is cut off:

Works fine for me! The gadget works fine here, although I also see the last line cut off in IE7. -------------------- |

Don't forget about the GISS Mars 24 sunclock

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. Andy |
