This afternoon, Spirit Rover will start it’s 999th Sol (Martian Day) on Mars. Tomorrow will be Sol 1K.
Next month, on the 14th/15th of November, Opportunity’s calendar will hit the same milestone. A Thousand Days on-planet.
Congratulations to all the teams who crafted, constructed,
controlled, and cajoled the rovers from conception to the current-day.
