A day on Mars is almost identical in length to a day on Earth

A Martian day — called a 'sol' — is 24 hours, 39 minutes, and 35 seconds: just 2.7% longer than an Earth day. Mars also has a similar axial tilt (25.2° vs Earth's 23.5°), giving it seasons comparable to Earth's, though each Martian season lasts roughly twice as long because the Martian year is 687 Earth days. These coincidences mean Mars has a more Earth-like day–night cycle than any other planet. They have also made rover operations relatively straightforward — NASA teams running Mars rovers operate on sol schedules, progressively drifting out of sync with Earth time over a mission.
