Space Disasters

NASA vigorously trains its astronauts to ensure they are physically fit, mentally strong, and as reliable as the strongest machines. But the fact is, even the brightest of people make mistakes...and in the unforgiving environment of space, any error, even a small one, can have life and death implications. Join us as we examine space disasters caused by human factors, from a handyman blunder that nearly ruined a million-dollar Hubble mission to a sight-seeing distraction that caused a Mercury spacecraft to return to Earth 250 miles off course.

Flying through bad weather can be a harrowing experience, and for NASA, it can be doubly unnerving, as violent storms can strike from below the atmosphere or above it. Witness the true power of nature in space and on Earth as astronauts and ground crews battle to overcome the elements, including a severe lightning strike that crippled Apollo 12's computer system, the freezing temps that compromised the Space Shuttle Challenger, and the tempest of space debris that sent a dead satellite on a collision course with the International Space Station.

Sending spacecraft into orbit is an unforgiving business. Every launch is a long, controlled explosion that can turn into a fiery spectacle at the smallest error. Join us as we examine space exploration's most disastrous liftoffs, from America's "risky rockets" (the Vanguard, Atlas, and Titan II) to the Nedelin catastrophe, a massive explosion that Russia kept secret for decades. Then see how lessons learned from early failures led to soaring triumphs, including the most famous and powerful rocket the world has ever launched: the Saturn V.
