What time is it on Mars?
It depends upon the spacecraft.
Time is uniquely established for each spacecraft operating on the surface of Mars.
Dates are measured in "sols" (days on Mars) relative to landing.
Hours and minutes are slightly longer than on Earth, accommodating the slightly longer Martian day.
Local and universal time are also shown.
