Hubble Space Telescope be kept in a clean room, powered up and purged with nitrogen, until a launch could be rescheduled. This costly situation (about per month) pushed the overall costs of the project even higher. This delay did allow time for engineers to perform extensive tests, swap out a possibly failure-prone battery, and make other improvements. Furthermore, the ground software needed to control Hubble was not ready in 1986, and was barely ready by the 1990 launch. Eventually, following the resumption of shuttle flights in 1988, the launch of the telescope was scheduled for 1990. On April 24, 1990, successfully launched the
Space Shuttle Columbia southern California. The facility is also a hands-on learning center with interactive exhibits, workshops, and classes about space science, astronautics, and the Space Shuttle program's legacy — providing educational opportunities for all ages. The Shuttle's final crew was honored in 2003 when the United States Board on Geographic Names approved the name Columbia Point for a mountain in Colorado's Sangre de Cristo Mountains, less than a half-mile from Challenger Point, a peak named after America's other lost Space Shuttle.
