Educational Spacewalk Simulation STS-125 Overview
 

The simulation begins with the capture of the Hubble Space Telescope using the Canadarm Robotic Arm.

One of the three spacewalks included in the simulation is the removal of the Wide Field Planetary Camera 2 and installation of the new Wide Field Camera. The first task represented in this simulation is the removal of the Wide Field planetary Camera 2, where an astronaut is held by the Canadarm Robotic Arm and moved into position for the removal. This camera is then removed and placed in a temporary storage location. The new Wide Field Camera is then removed from the space shuttle cargo bay and installed onto the Hubble Space Telescope. Finally, the Wide Field Camera 2 is taken from the temporary storage location and loaded into the space shuttle cargo bay for its return to earth.

Another spacewalk in the simulation is the replacement of the Corrective Optics Space Telescope Axial Replacement with the Cosmic Origins Spectrograph. The first task represented in this spacewalk simulation is the removal of the Corrective Optics Space Telescope Axial Replacement. The Corrective Optics Space Telescope Axial Replacement is placed in a temporary storage location and the Cosmic Origins Spectrograph instrument is removed from the space shuttle cargo bay and then installed onto the Hubble telescope. Finally, the Corrective Optics Space Telescope Axial Replacement is taken from the temporary storage location and loaded into the space shuttle cargo bay.

The remaining spacewalk in the simulation is the replacement of the batteries used to support Hubble telescope operations during periods of darkness. The simulation shows the removal of the old battery pack followed by the loading of this battery into the shuttle cargo bay. Then the new battery pack is removed from the shuttle cargo bay and installed into the Hubble telescope.

After the spacewalks have been completed, the simulation shows the release of the Hubble telescope. For more information on the Hubble Space Telescope, please visit http://www.nasa.gov/hubble.
