The STS-131 crew powered up Discovery’s flight control system and tested the flaps and rudder that will control the shuttle’s flight once it enters the Earth’s atmosphere. Next they test-fired the reaction control system jets that will control the shuttle’s orientation before it reaches the atmosphere. All seven crew members stowed items in Discovery’s cabin in preparation for re-entry and landing.
The first Kennedy landing opportunity on the mission’s 222nd orbit would see a deorbit burn at 7:43 a.m. EDT Monday for the 8:48 a.m. landing.
