Abandoned: International Space Station?

The International Space Station, which has been constantly manned since 2000, may have to be abandoned later this year following the launch failure of a Russian rocket last week. Until the problem with that rocket is resolved, there will be no way to get astronauts to the station. Robert Siegel speaks Doctor Leroy Chiao (chow), a former NASA astronaut, about what that would mean to the station and the six astronauts currently onboard.
