...Astronauts Bill Lenoir and Bob Overmyer experienced nausea and vomiting during the fifth flight of the Columbia last November. Lenoir's distress helped force changes in planned space tasks during the five-day mission. Space sickness, renamed by NASA "space adaptation syndrome" (SAS), was recognized only a decade ago. Says former Astronaut Mike Collins: "We didn't have much of a problem with space sickness as long as we were strapped in Mercury and Gemini. Same for the Russians. It's when we all began floating around in Skylab and the Russians in Salyut that the guys...
...cure because SAS can disrupt short-term flights. As a temporary remedy, astronauts routinely take along pills containing a combination of scopolamine, a drug that blunts sensations, and dextroamphetamine, a stimulant to counteract scopolamine's dulling effects on the body and mind. When the pills failed to help Lenoir, NASA's chief flight surgeon Sam Pool advised from Houston ground headquarters that Lenoir also take Phenergan, an antihistamine, and Dalmane if he needed a sleep medication. But the combination of potent drugs is not an ideal solution since it can impair coordination and judgment. According...
...astronauts since Skylab crew members exited into space in 1973 to make external repairs on their orbital laboratory. Mission controllers called off the latest walks after a vital oxygen-and-coolant circulating fan in Astronaut Joe Allen's backpack wheezed and sputtered, and the pressure in Astronaut Bill Lenoir's suit failed to reach acceptable levels...
...Although the investigators still have not found out why water should have penetrated the device's epoxy covering, they have made clear that its porosity should have been uncovered long before the $2.3 million suits ever went into orbit. There was, however, no doubt what went wrong with Lenoir's suit. Despite all efforts during the flight, the suit would not reach the required pressure, 4.3 Ibs. per sq. in. (Although this is only a third of the earth's normal atmospheric pressure, it is adequate because the astronauts are breathing pure oxygen rather than the oxygen...
...chip, perhaps a burr from a screw, in an exhaust vent of the suit's oxygen supply system. If the fragment had been in the pure oxygen area and caused a spark (by hitting a wall, for example), it might have touched off a catastrophic flash fire, killing Lenoir and possibly ripping a fatal hole in Columbia's sides as well. In fact, a suit did catch fire in a test at Houston two years ago; fortunately no one was wearing it. It was so incinerated that not enough was left to pin down the cause...
