 1984 marked a year of five space shuttle missions, together logging over 15.2 million miles in Earth orbit, living, working, and experimenting in space. We achieved what we had never done before. February. For the first time in history, man lost his dependency on a tent for spacewalks. Astronaut Bruce McCandless maneuvered 300 effortless feet away from the shuttle in his manned maneuvering unit. This new tool provides us with a means of extending man's physical presence outside the confines of the space shuttle. Challenger again flew in April in addition to capture and repair a failed scientific satellite called Solar Max. The satellite designed to study the sun was very carefully plucked out of orbit by the remote manipulator arm and birthed in the shuttle's payload bay. Jim Van Hofften and George Nelson spent over seven hours repairing its failed electronics before releasing it back into service. Never before had a satellite been retrieved and repaired while in Earth orbit. Another team effort made further advances during the October flight of Challenger. Kathy Sullivan and David Leistner completed tests on a new system developed for refueling satellites. Kathy Sullivan became the first American woman to walk in space. One month later, the crew of Discovery rounded out the year with an enterprising mission. The crew successfully deployed two satellites. Then astronauts Dale Gardner and Joe Allen ventured into space with specially adapted manned maneuvering unit. They snared two failed communications satellites and physically helped lower the multi-ton devices into safekeeping in the shuttle's payload bay. Skillful teamwork and the assistance of Dr. Anna Fisher with the remote manipulator arm made all this possible. Marking a year of many achievements, the space shuttle will continue to play a crucial role in our future space endeavors.
