...planned, the flight of Apollo 204 would have tested both the mettle and the technology of the three astronauts beyond anything that men had yet experienced in space. On Feb. 21, the capsule was to be fired off the ground by a Saturn 1-B rocket to go into orbit for as long as Grissom, White and Chaffee could take it, an "open-end" mission that marked a bold departure from the rigidly limited space flights of the past. It was to be essentially an engineering flight, a manned shakedown for the Apollo systems, which had already twice been fired...
...controls-gauges, dials, switches, lights and toggles. The service module below is essentially an engine room, housing fuel, the crew's oxygen, the basic electrical system, and a large rocket with 22,500 Ibs. of thrust to be used for space maneuverings, braking the ship into lunar orbit and supplying the propulsion necessary to send it back to earth. The whole capsule is 34 ft. long, weighs about 30 tons when fully fueled. Ultimately, the Apollo will also carry a lunar module, a buglike, rocket-powered ferry that two astronauts will board for the last-leg descent...
Grissom got that chance when he was picked as the pilot of America's first two-man spacecraft. With the launching of Gemini 3 on its three-orbit flight on March 23, 1965, Grissom became the first man ever to journey twice into space. Aided by Co-Pilot John Young, he scored yet another space first when he took over the controls himself, skill- fully piloted the craft through a series of tricky orbit-changing maneuvers. After that success, Grissom seemed to loosen up. The Apollo flight would have made him the only man to enter space three times...
...foot rope in his backyard on weekends, usually bicycled the three miles between his Houston home and the NASA Space Center. To his fellow astronauts, it came as no surprise when White took along a gold cross, a St. Christopher medal and a Star of David on his 62-orbit Gemini 4 flight, explaining afterward that they were "the most important thing that I had going...
...theories and given it a new twist that he feels will enable it to pass the mathematical and dynamical tests its predecessors failed. Physicist S. (for Siegfried) Fred Singer suggests that the moon first evolved as a minor planet, independent of the earth and following its own orbit around the sun. About four billion years ago, he believes, its path carried it on a near-collision course with the earth, which at that time was an atmosphereless orb revolving once every five hours. Captured by terrestrial gravity, the moon was pulled into an elliptical orbit around the earth, passing...
