Working inside Orbiter Processing Facility-3 at NASA's Kennedy Space Center in Florida, technicians are beginning a three-day leak test of space shuttle Discovery's entry closed loop gaseous nitrogen life support system. Tonight, workers will perform a similar test of the spacecraft's external tank umbilical. The shuttle's glass cockpit displays also are undergoing testing. Discovery is slated to be carried to the Vehicle Assembly Building on Sept. 8. Launch is targeted for Nov. 1.
The six STS-133 mission astronauts are in the fixed-base simulator at NASA's Johnson Space Center in Houston, the training base for NASA's astronauts. The crew is rehearsing the installation of ELC-4, a procedure they will perform during the mission to the International Space Station.
