Atlantis Gets Propellants as STS-135 Astronauts Prep for Mission

Early this morning at NASA’s Kennedy Space Center in Florida, teams at Launch Pad 39A began loading propellant into space shuttle Atlantis’ auxiliary power unit. The fuel loading will continue through the day.

The four STS-135 astronauts are back at their home base, NASA’s Johnson Space Center in Houston. Their training agenda for today includes a review of procedures for the spacewalk scheduled on the fifth day of the mission.
