The crew of space shuttle Discovery was awakened at 12:21 a.m. EDT by Louis Armstrong singing “What a Wonderful World,” played for Mission Specialist Stephanie Wilson, who completed her third trip to the station on Discovery on Saturday. Wilson flew on Discovery for STS-121 in July 2006 and STS-120 in October 2007.
The STS-131 crew will prepare for landing by checking out Discovery’s flight control systems and performing a hot-fire test of its reaction control system. Landing is scheduled for Monday at 8:48 a.m. at Kennedy Space Center.
