WebOn February 1, 2003, Space Shuttle Columbia disintegrated as it reentered the atmosphere over Texas and Louisiana, killing all seven astronauts on board. It was the second Space Shuttle mission to end in disaster, after the loss of Challenger and crew in 1986. Web5. mar 2024 · The way spacecraft do this is via one reentry burn using the best estimates of the atmosphere, and doing some slight corrections to the path while reentering. The best example of this is the Space Shuttle, which could precisely land due to the aerodynamic surfaces, however, every spacecraft has some ability to steer itself inside the atmosphere.
