Effects of Zero-G. The medical concern was not unwarranted. All three astronauts were unsteady as they emerged from the spacecraft, and Astronaut-Physician Kerwin needed a slight assist as the three Navymen walked to a waiting mobile medical lab. Then, as the carrier steamed to San Diego, doctors began an intense, six-hour examination aimed at answering many questions relating to the prolonged flight. For example, had there been irreversible damage to the astronauts' cardiovascular systems or excessive loss of calcium from their bones...
...nuisance. Besides ruining food, the high temperatures in the orbital workshop section (caused by the loss of its outer shielding) also ruptured two-thirds of Skylab's toothpaste tubes, as well as all of the containers of hand cream, stocked to lubricate the skin in the spacecraft's dry atmosphere. The astronauts could console themselves with once-a-week showers, but pleasant as the bathing was, it was also very taxing. Water tended to cling firmly to the body and to the shower compartment's walls. As a result, Kerwin said, "it takes forever to dry both...
...While Conrad held the rope to the cutters, Kerwin tried to direct the pole so that the blades hooked around the aluminum strip. "I can't stabilize myself," he complained as he failed again and again. "I just can't do it." Finally, just as the spacecraft was about to make another pass into darkness-which would have forced the astronauts to halt their work because the illumination from the hatch area did not reach the solar wing-the cutter moved into place...
...prudent rationing (turning off unnecessary lights, curtailing some experiments), the astronauts were able to perform most of their scheduled tasks. When they flipped Skylab over to begin earth-surveying photography with six high-resolution cameras, the functioning solar panels were turned away from the sun, forcing the spacecraft to rely temporarily on its storage batteries...
...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 also beamed a lively TV show to earth and showed off their ability at handstands, backflips and racing round the spacecraft...
