STS090-774-028 (29 April 1998) --- This view features a 13,980-foot mountain peak in Colorado’s Sangre de Cristo Mountains in Saguache County, photographed by crewmembers of the STS-90 Space Shuttle Columbia mission in April 1998. EDITOR’S NOTE: In June 2003, the summit was named “Columbia Point” by the U.S. Department of Interior in memory of the STS-107 Space Shuttle Columbia crew, lost in an accident on February 1, 2003, and for the scientific exploration, technical excellence, and the dream of spaceflight for which the mission stood. Columbia Point is located on the east side of Kit Carson Mountain. On the northwest shoulder of the same mountain is Challenger Point, a peak previously named in memory of the Space Shuttle Challenger, which exploded soon after liftoff on January 28, 1986.
