Space processing viewed by a scientist-astronaut

An account is given of NASA astronaut T. G. Wang's 1985 experiences with Spacelab-borne containerless processing experiment equipment handling and experimental management. The mission in question was marred by the initial malfunction of the zero-gravity materials-processing experiment package; Wang's first task was accordingly to attempt repairs, and led to his living inside the experiment package for 2.5 days in order to operate the system as well as possible, on a 16-hr workday basis, with the assistance of two other astronauts.
