Are there other astronauts who were injured by a hard landing or a hard reentry?
Apollo 12, Alan Bean. The capsule hit a rising wave, and the impact force knocked a camera out of a bracket, which hit Bean in the head and briefly knocked him out. He suffered a mild concussion and needed six stitches, but had no permanent injury.
Boris Volynov broken several teeth during hard landing of the Soyuz-5 mission.
American cosmonaut Donald Pettit injured his shoulder when the Soyuz TMA-1 had to fall back to a ballistic reentry following a capsule malfunction. The hard landing was further complicated by the parachute dragging the capsule along the ground after landing. Pettit was immediately moved from the landing site by a rescue helicopter.
The female South Korean astronaut Yi So-yeon may have been injured in Soyuz TMA-11 on April 19, 2008.
Yi So-yeon was hospitalized after her return to South Korea due to injuries caused by the rough return voyage in the Soyuz TMA-11 spacecraft. The South Korean Science Ministry stated that the astronaut had a minor injury to her neck muscles and had bruised her spinal column.
Due to a malfunction with the Soyuz vehicle, the craft followed a ballistic re-entry which subjects the crew to severe gravitational forces up to 10 times the amount experienced on Earth.
Yi was hospitalized after her return to Korea due to severe back pains. Though many believed these pains were the result of the rough landing, they were in fact normal and expected. They were the result of spinal re-compression.
So the back pain may have been caused by either the reentry or by the prior stay in weightlessness.
