NASA landed Spirit and Opportunity, twin Mars rovers on the Red Planet, 10 years ago this month.
Spirit landed on January 4, 2003 with Opportunity touching down on January 25th. (Note: The landing times are based on Eastern Standard Time. The landing date on the west coast, 3 hours earlier than EST, was the day before.)
The original mission length was 3 months.
Both rovers completed their mission successfully with Opportunity still roaming the surface of Mars today.
NASA lost communication with Spirit in March of 2010.
NASA's Jet Propulsion Laboratory (JPL) manages the mission and is located at the California Institute of Technology.
To celebrate the historic landing and the success of the mission, NASA has events planned all month long.
Although most events are far away from Arizona, there are opportunities to interact online.
