Not Mariko Tanaka - the other Spirit! NASA's famous Mars rover Spirit has survived to see its sixth birthday. It first touched down on January 4, 2004 with an expected life of just ninety days. Its twin, Opportunity, landed on January 25, 2004. Although the first robot has been largely stuck since May, the Jet Propulsion Laboratory team responsible for it is hopeful that they will be able to dislodge the unit before Mars' winter sets in. JPL programmer Eddie Benowitz wanted to share this video where the team talks about the mission's impressive accomplishments to date.
