...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...
...luck seemed behind the spacecraft at last. Forgotten for the moment was the mare's nest of trouble that had postponed the flight for two days. Fuel cells running low on fuel, liquid hydrogen boiling uselessly away, telemetering equipment turned suddenly unreliable, fire near the launch pad, thunderstorms aloft−all seemed problems of the past. Now everything was going well; Gemini's orbit was incredibly exact. "Everything is fine," reported Command Pilot Gordon Cooper. "You are go! You are go!" exulted Astronaut Jim McDivitt, capsule communicator in the Mission Control Center near Houston...
...smaller and lighter than the conventional batteries used on all previous space flights. Unlike conventional batteries, they can supply electricity for as long as they are fed their fuel−an ideal trait for long-duration power supplies. They produce electricity through the continuous chemical reaction of oxygen and hydrogen, and in the process they form water, a most valuable byproduct...
...cell's hydrogen and oxygen are both stored in spherical tanks in a supercold liquid state. Warmed by electric heaters, they turn to gas, build up pressure and push themselves into the cells. And those heaters are among the least complicated devices on the spacecraft: a filament of gold-plated wire curving around the tank. The same type of device is a veteran of all the manned Mer cury and Gemini flights, being used to convert liquid oxygen into gas for the astronauts to breathe. When oxygen pressure started falling in Gemini 5, it was a sure sign that...
...inflammable gas, he said. early-morning explosion at the , which is operated jointly Harvard and M.I.T., injured 7 and killed a 19-year-old technology At the time of the blast, the chamber was in the final stages of a program for cooling it and filling it with liquid hydrogen that was being tried for the first time...
