CAPE CANAVERAL, Fla. -- In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, STS-133 crew members look on as SSPF technicians below describe the payload. From left to right are Mission Specialists Tim Kopra, Nicole Stott, Michael Barratt and Pilot Eric Boe. 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
