The seven-member crew of NASA’s next space shuttle flight and Space Shuttle Program managers will participate in a series of media briefings June 8 at the Johnson Space Center, Houston. The briefings begin at 8 a.m. CDT and will be broadcast live on NASA TV. Reporters at participating NASA locations may ask questions.

Space Shuttle Discovery’s launch is targeted for July 1 in a launch window that extends to July 19. The mission, designated STS-121, will continue evaluating new shuttle safety improvements, many of which first flew on Discovery’s July 2005 mission. The improvements include a redesign of the shuttle external fuel tank’s foam insulation, in-flight inspection of the shuttle’s heat shield, improved imagery during launch and the ability to launch a shuttle rescue mission if needed.

Discovery will carry supplies and a third crew member to the International Space Station. At least two spacewalks are planned during the 12-day mission, which also includes repair work to the station.
