Virtual image showing Spirit rover on Mars

The Mars rover, Spirit, has completed one martian year on the planet’s surface–that’s almost two Earth years. Having survived seven times its expected lifetime (of 90 martian days, or sols) and traveling over 3 miles (about 5,000 meters), Spirit is still going strong.
