Description Astronaut Bruce McCandless II, mission specialist, participates in an extravehicular activity a few meters away from the cabin of the shuttle Challenger during the STS-41B mission. He is using a nitrogen-propelled hand-controlled Manned Maneuvering Unit. This was the first time an astronaut performed a spacewalk without being tethered to the shuttle.

Title McCandless on Arm in Aft Payload Bay
Full Description Astronaut Bruce McCandless II, STS-41B mission specialist, tests a Mobile Foot Restraint (MFR) attached to the Remote Manipulator System (RMS) aboard the Space Shuttle Challenger. McCandless appears to be walking on cargo, but is realy being flown over it by the combination MFR and RMS. His helmet visor reflects parts of the payload bay that can't be seen in the larger portion of the photo. Behind him can be seen both the Orbital Maneuvering System (OMS) pods.

Backpacking
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.

To Fly Free in Space
Title To Fly Free in Space
Explanation At about 100 meters from the cargo bay of the space shuttle Challenger, Bruce McCandless II was further out than anyone had ever been before. Guided by a Manned Maneuvering Unit [ http://www.astronautix.com/craft/shulemmu.htm ] (MMU), astronaut McCandless, pictured above [ http://grin.hq.nasa.gov/ABSTRACTS/GPN-2000-001087.html ], was floating free in space. McCandless [ http://www.jsc.nasa.gov/Bios/htmlbios/mccandless-b.html ] and fellow NASA astronaut [ http://www.jsc.nasa.gov/Bios/index.html ] Robert Stewart [ http://www.jsc.nasa.gov/Bios/htmlbios/stewart-rl.html ] were the first to experience such an "untether [ http://www-istp.gsfc.nasa.gov/Education/wtether.html ]ed space walk [ http://antwrp.gsfc.nasa.gov/apod/ap990801.html ]" during Space Shuttle [ http://antwrp.gsfc.nasa.gov/apod/ap990411.html ] mission 41-B [ http://en.wikipedia.org/wiki/STS-41-B ] in 1984 [ http://www.online-literature.com/orwell/1984/ ]. The MMU [ http://galacticvoyager.com/pat/mmu/ ] works by shooting jets of nitrogen [ http://periodic.lanl.gov/elements/7.html ] and has since been used to help deploy and retrieve satellites. With a mass over 140 kilograms, an MMU is heavy on Earth [ http://antwrp.gsfc.nasa.gov/apod/ap070325.html ], but, like everything, is weightless when drifting in orbit. The MMU was replaced with the SAFER [ http://antwrp.gsfc.nasa.gov/apod/ap011002.html ] backpack propulsion unit.

Description Astronaut Bruce McCandless II, 41-B mission specialist, tests a mobile foot restraint (MFR) attached to the remote manipulator system (RMS). The aft portion of the Challenger, to which the RMS is connected, is seen in the lower left corner. The protective cradle that the WESTAR VI satellite used in the left corner of the frame. Below McCandless can be seen the cloudy surface of the earth (27037,27040), McCandless "rides" the RMS arm during a lengthy EVA. The 41-B mission specialist has his eyes on the shuttle pallet satellite (SPAS-01A) in the middle of the Challenger's cargo bay (27038), McCandless appears to be walking on cargo, but is realy being flown over it by the combination of MFR and RMS. His helmet visor reflects parts of the payload bay that can't be seen in the larger portion of the photo. Behind him can be seen both the orbital maneuvering system (OMS) pods (27039).
