...Houston's Manned Spacecraft Center, unflappable Chris Kraft every day faced the decision of whether to keep Cooper and Conrad going for still another day. From start to finish, the "go-no go" decision hinged on Gemini's cantankerous fuel cell. A failure in its liquid oxygen supply tank nearly terminated the mission on the first day, and the faulty heating unit that caused the problem never did kick on. As the flight soared into the second day, the oxygen pressure slowly moved upward-and optimism soared at Houston command. "The morning headline," broadcast Kraft to the astronauts...
...trickle of oxygen became a steady stream, joining in a chemical reaction with hydrogen to produce the electricity to run the craft's computer, radar, communications and environment-control systems. For reasons not yet fully understood, the pressure inside the oxygen tank increased as the volume of liquid oxygen decreased while it was being used. Soon the fuel cell was supplying Gemini with all the electricity it needed, and the astronauts began switching their systems back on. Fuel-cell experts had actually underestimated the system's efficiency, were surprised that they could get sufficient power with such...
...told them that airplanes were on their way to the Pacific recovery area, adding, "We hope we don't have to use them, but it will be a good exercise for them, and they'll be there if you need them." While they talked, though, the oxygen pressure dropped still lower−to 95 Ibs. If it fell to 20 Ibs., the spacecraft would have to switch to its back-up batteries, which produce just enough power to handle an orbit and a half, plus re-entry and recovery time...
...were involved; no manned U.S. spacecraft had ever failed to complete its planned mission. But Kraft, as ever, was the cool and deliberate flight engineer. He used every available moment to weigh every contingency. He ran a check of the spacecraft. All the key systems, such as cabin pressure, oxygen flow and cabin and suit temperature, were normal and running perfectly...
...company will also construct new oxygen furnaces and blast furnaces, at least two continuous casting lines, finishing facilities and light structural steel and bar plants. The ambitious program is intended to replace the last of U.S. Steel's collection of obsolete equipment, better enabling the company to withstand the assaults of more modernized U.S. and foreign competitors, the inroads of substitute materials such as aluminum and plastics and the ever-present specter of rising labor costs...
