One of two Mars rovers that would perform beyond expectations after landing on the Red Planet in our solar system was launched on this day in history.
Spirit was one of two Mars Exploration Rover missions, and was launched into space aboard a Delta II rocket on June 10th, 2003.
It would land on Mars on January 4th of 2004, and transmit its first pictures back six days later.
The original goals of Spirit were to last just over 90 days and to travel less than half a mile. However, Spirit was an extreme success, lasting nearly seven years and traveling almost five miles across the Martian surface.
In that time, the rover returned pictures and video, including one of a dust devil on the Martian surface. It also had drilling tools and instruments to study rocks on the Martian surface.
Its sister rover, Opportunity, is actually still active and working on Mars as of 2014
