...landing, he assembled a complex stereo system. Last week the 43-year-old Navy captain continued to live up to his reputation as Houston's No. 1 amateur mechanic. During a daring and dangerous four-hour walk in space-the longest ever attempted-he and Fellow Astronaut Joseph Kerwin freed Skylab's jammed solar wing, thus probably saving the mission and brightening chances for the completion of the $2.6 billion Skylab program...
...Kerwin went outside through a small side hatch in the airlock module...
...astronauts' most significant observations were of their own physiological reactions to space. All three seemed to be adjusting well to weightlessness. Astronaut Joseph Kerwin, the first American doctor in space, discovered that "you do have a sense of up and down" in zero-G. Explained Kerwin: "You say to your brain: 'Brain, I want that way to be up,' and your brain says: 'O.K.' " Speculating about this unexpected phenomenon, Kerwin doubted that it was connected with the balance mechanism in the inner ear. "I think it's strictly eyeballs and brain," he said...
...Under Kerwin's supervision, the crew conducted a host of biomedical tests-swirling about in a rotating chair to study disorientation in zero-G, climbing into a pressure chamber that measures the accumulation of blood in the lower body, contributing daily samples of blood (and freezing them) for laboratory analysis back on earth. Only Skylab's bicycle exerciser, designed to measure the astronauts' stamina, gave the crew any trouble. Confronted by the heat and some badly adjusted straps on the machine, Astronaut Paul Weitz found that pedaling was too exhausting and cut the experiment short. The astronauts...
Conrad undocked and maneuvered Apollo to Skylab. Wearing a bulky space suit, Weitz leaned out of Apollo's hatch (while Kerwin held onto his knee to keep him from drifting out into space) and attempted to pull the jammed panel loose with a long-handled tool resembling a boat hook. The panel would not budge. After an hour of pushing, shoving and tugging-interspersed with streams of obscenities clearly audible to millions-the task seemed hopeless. "I hate to say it," said the exasperated Weitz, "but we ain't going to do it with the tools...
