Almost immediately it was realized that the optical performance was not as expected; analysis of the flawed images showed that the primary mirror had been ground to the wrong shape, resulting in spherical aberration. Fortunately, the Hubble telescope had been designed to allow in-space maintenance, and in December 1993, mission STS-61 carried astronauts to the Hubble to make corrections and change some components. A second repair mission, STS-82, was made in February 1997, and a third, STS-103,

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.
