What is Spirit (rover)?
{{italictitle}} [[File:NASA Mars Rover.jpg|thumb|Artist's portrait of ''Spirit'' on [[Mars]].]] '''''Spirit''''', also known as '''MER-A''' ('''Mars Exploration Rover – A''') or '''MER-2''', was a [[Robotics|robotic]] [[rover]] that was active on [[Mars]] from 2004 to 2010. It was part of the [[Mars Exploration Rover]] program, and the rover's twin, ''[[Opportunity (rover)|Opportunity]]'' (also known as MER-B), was launched to the other side of the planet. ''Sprit'' got stuck in a sand trap, and, due to freezing temperatures, the rover made its last communication with [[NASA]] on March 22, 2010. ytvkg {{tech-stub}} [[Category:NASA spacecraft]] [[Category:Planetary rovers]] [[Category:Spacecrafts launched in 2000s]]
