NASA flight directors will evaluate weather conditions at Kennedy before permitting Atlantis and its crew to land. If weather prevents a return to Kennedy on Friday, the backup landing site at Edwards Air Force Base in California will be activated Saturday for consideration as well.
After touchdown in Florida, the astronauts will undergo physical examinations and meet with their families. The STS-125 crew is expected to hold a news conference about four and a half hours after landing Friday. Both news events will be broadcast live on NASA Television.
