The Discovery's landing has been postponed til Monday night because of rain in Florida, MSNBC said.
NASA's seven astronauts were scheduled to land at Kennedy Space Center at 8:48 a.m., ET after a 14-day mission to resupply the International Space Station, MSNBC said.
NASA prefers to land in Florida due to costs of bringing a shuttle back to base after landing, Reuters said.
The Discovery has supplies to last them until Wednesday, but the will land regardless sometime Tuesday even if that means landing in Edwards Air Force Base in California, Reuters said.
