The range is named to memorialize the Space Shuttle "Columbia" disaster. On February 2, 2004, the individual peaks of the Columbia Hills were named after the seven astronauts who died in the disaster. "Spirit" spent a few years exploring the Columbia Hills until it ceased to function in 2010. It is also considered a potential landing site for the "Mars 2020" rover.
