Science Teachers Turned Spacewalkers for the STS-119 Mission
Two educators who are now fully trained NASA astronauts will make their first journey into orbit on space shuttle Discovery's upcoming mission to the International Space Station. During the STS-119 mission, Joseph Acaba and Richard Arnold will step outside the station to conduct critical spacewalking tasks. Acaba taught at Melbourne High School and Dunnellon Middle School in Florida. Arnold taught science and mathematics at several schools in the U.S. and overseas, including John Hanson Middle School in Waldorf, Md.
Discovery is targeted to launch from NASA's Kennedy Space Center in Florida no earlier than Feb. 25, 2009. The shuttle will deliver the space station's fourth and final set of solar arrays, thus completing the complex's backbone, or truss.
