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. |
