STS-133 lead spacewalker hurt in a bicycle accident:Spaceflight Now
"Space station veteran Timothy Kopra, scheduled for launch Feb. 24 aboard the shuttle Discovery, was injured in a bicycle accident Saturday, a NASA official said. The injury was not life threatening and the NASA official, citing medical privacy issues, provided no additional details. But multiple sources said Kopra may have broken his hip, raising the prospect of a significant impact to the already-delayed mission. "
バックアップ・クルーは用意してない？驚き
NASA does not train backup crews and a replacement, even a recently flown veteran, would need time to rehearse spacewalk scenarios and receive mission-specific training for Discovery's flight.
