Meet NASA Astronaut Joe Acaba


Joe Acaba is experiencing a teacher's dream. His career began in the classroom, and then he made the leap into the world of science and mathematics that he was teaching about. That leap took him farther than he ever imagined - on an extended stay in low Earth orbit on the International Space Station.

Acaba was selected for the NASA Astronaut Candidate Class of 2004 while teaching middle school mathematics and science at Dunnellon Middle School in Florida. He was one of three classroom teachers selected as mission specialists. He completed Astronaut Candidate Training in 2006, which made him eligible for spaceflight. Acaba's first trip to space was as a mission specialist on space shuttle mission STS-119 in 2009, where he performed two spacewalks. Acaba's next space assignment was flight engineer on the International Space Station as a member of the Expedition 31 and 32 crews. He launched on a Russian Soyuz rocket on May 14, 2012, on his way to the station and returned to Earth on Sept. 16, 2012.
