There are two opportunities for Endeavour to return home to Florida on Friday. The first begins with an engine firing at 11:51 a.m. Central Time leading to a 12:57 p.m. touchdown in Florida. A second opportunity is available with a 1:27 p.m. deorbit burn leading to a 2:33 p.m. landing.
Flight controllers will continue to monitor weather forecasts throughout the day. Preliminary forecasts indicate a continuing chance of clouds and rain over the next 24 hours. The alternate shuttle landing site at Edwards Air Force Base in California will not be called up for support Friday.
