On the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, one of the Shuttle Training Aircraft is ready for STS-119 Commander Lee Archambault or Pilot Tony Antonelli to practice shuttle landings on the Shuttle Landing Facility's runway. The mission crew members arrived in the afternoon at Kennedy to prepare for launch. The mission is the 28th to the International Space Station and the 125th space shuttle flight.
