Space shuttle Discovery’s hydraulics systems are to be cycled today during launch processing for the STS-133 mission, targeted for launch on Nov. 1. Hydraulics are used to operate flight controls, the swiveling of the main engines and other functions. The processing work is being performed at NASA’s Kennedy Space Center in Florida.
Mission Specialists Tim Kopra and Alvin Drew will rehearse procedures for the mission’s second spacewalk in the Neutral Buoyancy Laboratory at NASA’s Johnson Space Center in Houston today.
