...final hours of their first EVA (extravehicular activity), the astronauts will collect rocks and try to obtain a 15-in. core of the lunar soil. One prize that geologists hope they will bring home: some of the debris showered on the landing site billions of years ago when a huge meteor gouged out the crater Copernicus, 230 miles to the north. That may well be possible. A three-mile-wide "ray" of material apparently ejected from Copernicus cuts directly through Apollo 12's base at the Ocean of Storms...
...them are the flight director and planning and operations officers. "Flight" is the captain of the team, the man who makes the crucial decisions. Head flight for Apollo 11 was Cliff Charlesworth, 37. His green team handled liftoff, translunar insertion and the moon walk, known in space jargon as "Extravehicular Activity," or EVA. Charlesworth admits he liked EVA least of all the mission's activities, "because there just wasn't much I could do." Other flight directors for Apollo 11 were Gene Kranz, 35, who wears a white vest to match his team's color; Milt Windier...
Some ten hours after the landing, Armstrong will begin EVA (extravehicular activity), backing feet-first out of the hatch, on his belly. On the LM's "porch," he will pull a ring that opens a storage area and exposes a mounted TV camera, which will relay to audiences on earth a view of his awkward progress down the LM's ladder. At the bottom, Armstrong will place his right foot in the bowl-shaped footpad and?by 2:22 a.m. Monday, if he is on schedule?plant his left foot firmly on lunar soil...
...Womb at the Top." To abandon a foundering spacecraft, the astronaut dons extravehicular activity (EVA) gear, seals himself in the lifeboat and vents carbon dioxide and excess oxygen from his EVA suit to power the craft's attitude-control system. Face pressed against the porthole, he aligns his lifeboat with the horizon by firing the attitude-control jets. After sighting a landmark on earth with the reticle marked on the porthole, he aims and fires the retrorocket for 100 seconds, thus braking the lifeboat to a de-orbiting speed of 16,500 m.p.h. Then the retrorocket is jettisoned...
...problem could arise during any extravehicular activity, and the answer seems simple: haul in the tether. But in frictionless space, the free-floating astronaut is orbiting the spaceship as it circles the earth, and any attempt to pull him in would make him rotate around it so fast that he would be ultimately subjected to fatal G forces. He would also be moving at an uncontrollable speed when he finally reached-and crashed into-the spacecraft...
