Russia put off its manned spacecraft mission because

U.S. officials say the International Space Station may need to be temporarily evacuated unless Russia proceeds with the launching of its Soyuz rockets by November. NASA space station program manager Mike Suffre-dini said the six astronauts aboard the ISS may have to leave the craft unless Russian scientists discover what caused last week’s crash of an unmanned cargo ship that was headed to the facility.(6)On Monday, Russia postponed its next manned spacecraft mission to the ISS by at least a month after an unmanned ship using a similar rocket crashed into Siberia on August 24. The vessel was carrying three tons of supplies to the space station. The ISS crew three Russians, two Americans, and one Japanese cannot stay in orbit for longer than six consecutive months because of the risk posed by exposure to radiation. Three astronauts are scheduled to leave the space station next month: the other three are due to leave in mid-November.
