It turns out it was a technical malfunction, not a mistake by the crew, which caused last week’s Soyuz landing to be unexpectedly hard. Russian cosmonaut Nikolai Budarin and American astronauts Kenneth Bowersox and Donald Pettit landed 500 kilometres short of their destination in Kazakhstan on May 4th, and had a pretty rough ride. It appears the problem was a malfunction in the spacecraft’s control system, but experts in Russia haven’t been able to reproduce the problem. Investigators have called upon Russia to change the way they recover spacecraft, to position recovery aircraft and vehicles along the return path.
