Extravehicular Activity
Left:STS-88, Right:STS-96 |
During this flight, four astronauts in two groups will conduct a total
of four extravehicular activities (EVAs), two EVAs for each group.
Since there are not enough crew body restraint facilities in the Space
Shuttle cargo bay, one of the crew members will fix his foot on the end
of the shuttle robot arm operated by astronaut Wakata and will be transported
by the arm while performing the EVA.
During the EVA, the crew member who operates the robot arm in the cabin
and the EVA crew members must communicate closely. EVA simulation training
is repeated on the ground using the Neutral Buoyancy Laboratory (NBL)
located in Johnson Space Center before departing for space.
Also during EVA, crew members don a Simplified
Aid for EVA Rescue (SAFER), which is a small, self-rescue thruster
system for emergencies. However, SAFER will not be used except for a real
emergency.
EVA tasks planned for STS-92 are shown in the table below, but the tasks
are being revised and are subject to change.
