WASHINGTON, June 21 (RIA Novosti) - The landing of the Atlantis shuttle at Cape Canaveral has been postponed by at least an hour and a half, a spokesperson for NASA's Johnson space center said Thursday.
Brandi Dean said her agency was considering a landing time of 15:30 ET (19:30 GMT), or about 90 minutes later than originally planned.
Dean said the crew had enough resources to stay in orbit safely until Sunday, but added that this was an emergency option. She said weather forecasts inspired the hope the landing could be carried out Thursday or Friday.
A spokesperson for the Kennedy space center at Cape Canaveral in Florida said the delay was due to expected thunderstorms, but added the shuttle could still land either at Canaveral later or at NASA's secondary landing site at Edwards Air Force base in California.
She also said the astronauts would have another four attempts to land the shuttle at Canaveral and four tries at Edwards on Friday and Saturday, or at a reserve landing site in New Mexico.
