Space Shuttle Legacy

The Challenger disaster led to a reevaluation of the space shuttle program, resulting in increased safety measures and a shift in focus towards the International Space Station. However, the tragic loss of Columbia highlighted the shuttle's shortcomings, revealing that traditional rockets might be more cost-effective. Ultimately, the shuttle program concluded in 2011, leaving a gap in U.S. human spaceflight capabilities until the advent of new technologies like SpaceX's reusable rockets.
