With the help of NASA Ames Research Center and Johnson Space Center/Neutral Buoyancy Lab, DigitalSpace took underwater training video and analyzed it frame by frame in order to create the most realistic models and spacewalks.
Here, the simulation interface is shown, including the options to jump to spacewalks, to access camera views, to fast forward, or to find lost items.
The simulator requires a Windows computer and a good 3D graphics card.
A virtual astronaut works on replacing the Hubble Space Telescope's batteries. An additional part of the simulator is a game in which users try to find five items hidden around the Hubble telescope. Those who locate all five will receive a "surprise."
