Martian time

NASA’s Mars Surveyor 2001 lander will deliver a sundial to the Red Planet.
After it reaches Mars in January 2002, NASA plans to show live images of the
8-centimetre-square sundial and a calibrating overlay on the Web so that viewers
can tell the time on Mars. Children submitted over 160 design ideas for the
instrument, which was unveiled this week by the host of the popular American
children’s television programme Bill Nye the Science Guy.
