In the Launch Control Center at NASA's Kennedy Space Center in Florida, United Space Alliance Guidance and Navigation Engineer Jennifer Guida sits at her console in Firing Room 4 along with other STS-133 launch team members to rehearse procedures for the liftoff of space shuttle Discovery's final mission. The team at Kennedy also participated in launch simulations with personnel at NASA's Johnson Space Center in Houston.
Discovery's next launch opportunity to the International Space Station on the STS-133 mission is planned for no earlier than Feb. 24. For more information on STS-133, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts133/. Photo credit: NASA/Kim Shiflett
