In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, STS-133 Mission Specialists Tim Kopra (left) and Alvin Drew inspect a component of the payload as Mission Specialist Michael Barratt and Pilot Eric Boe look on.

The astronauts are at Kennedy to participate in the Payload Crew Equipment Interface Test, or CEIT, which gives the crew an opportunity for hands-on training with tools they'll be using in space and familiarization of the payload they will be delivering to the International Space Station. Launch of space shuttle Discovery is targeted for Nov. 1 at 4:40 p.m. EDT. For more information visit, www.nasa.gov/shuttle. Photo credit: NASA/Jack Pfaller
