Training for the Hubble Space Telescope (HST) servicing mission. Astronaut Jeffrey Hoffman wearing the helmet and data gloves of a virtual reality (VR) system during training for Shuttle Mission STS-61. The VR system is being used for the first time in astronaut training to simulate the capture and repair of the orbiting HST.
