Astronaut training. Astronauts Michael J Bloomfield (striped shirt) and Ellen Ochoa (far right) during a virtual reality simulation of the handling of the Space Shuttle in orbit. A representation of the International Space Station (ISS) is at top centre. This program allows the astronauts to familiarise themselves with the controls of the Space Shuttle before they fly it. This training was part of the preparation for mission STS-110, which flew from 8th-19th April 2002. It delivered new components to the ISS. Photographed at Johnson Space Center, Houston, Texas, USA.
