Title
"Backpacking"
Full Description
Mission Specialist Bruce McCandless II ventured further away from the
confines and safety of his ship than any previous astronaut ever has.
This space first was made possible by the Manned Manuevering Unit
or MMU, a nitrogen jet propelled backpack. After a series of test
maneuvers inside and above Challenger's payload bay, McCandless went
"free-flying" to a distance of 320 feet away from the Orbiter.
The MMU is controled by joy sticks positioned at the end of the arm
rests. Moving the joy sticks left or right or by pulling them fires
nitrogen jet thrusters propelling McCandless in any direction he
chooses. A still camera is mounted on the upper right portion of the
MMU.
This stunning view shows McCandless with the MMU out there amongst the
black and blue of Earth and space.
