Ten years ago today, the second of two NASA rovers landed on Mars for a planned 90-day mission.

After five years, one of the rovers - Spirit - became immobilised.

Exactly ten years into its 90-day mission, the other rover, Opportunity, is still doing useful work. Although you wouldn't want to use it for your daily commute - in that ten years, it's only driven 23 miles.

For more information, see:

It is an amazing achievement. Ninety days has become ten years.

Long may it continue roving.
