What do the clocks on the Phoenix and NASA websites represent?
The clock on our website represents the current time on Mars (similar to the clock on your computer telling you the current time on Earth). NASA’s clock is a mission elapse time and represents the number of hours Phoenix has been on Mars. Sol 0 is the day Phoenix landed: Every day the Sol clock will go up by one.
