A Sundial for Mars
The Mars Surveyor Lander, scheduled to arrive on Mars in 2002, carries a sundial. This instrument, inspired by Bill Nye, helps measure time by the shadows the Martian sun casts. Sundials were once crucial timekeepers on Earth, and this one allows a public display of time on another planet. It also serves a practical purpose, aiding in camera calibration for the mission.
