RE: Sundials on other planets

[Ian Clarke]

The sundial at the link below was originally designed to go on the Mars 
Surveyor mission that would have landed this year.  The dial would have doubled 
as a camera calibration object.  The mission was canceled in the revamp of 
NASA's Mars program, and I don't know if the dial will accompany a future 
lander or not.
