KENNEDY SPACE CENTER (AP) - The space shuttle Atlantis is going to stay in orbit for at least another day.
NASA has waved off Thursday's landing opportunities because of showers and clouds at Kennedy Space Center.
There are five more landing opportunities over the next three days. And Mission Control says weather conditions should be better at the Florida landing site Friday or Saturday.
A backup site in California could also be used Friday -- and, on Saturday, another site in New Mexico would also be an option.
Atlantis has enough power for its systems to orbit until Sunday.
There were showers within 34 miles and clouds within 8,000 feet Thursday. Both violate flight rules.
The shuttle and seven astronauts are returning from the international space station.
