...surface Aldrin reported: "Quantity light." The light signaled that only 114 seconds of fuel remained. Armstrong and Aldren had 40 seconds to decide if they could land within the next 20 seconds. If they could not, they would have to abort, jettisoning their descent stage and firing their ascent engine to return to Columbia...
...would be?dangerous enough. At any point during the eight-day journey, a massive failure of the electrical or oxygen systems, or a collision with a large meteor would almost surely result in tragedy. But lift-off was the most nerve-racking part of the mission. If the ascent engine had failed to start, Eagle would have been stranded on the lunar surface. Too short a burn would have tossed the module into a trajectory that would send it smashing back onto the lunar surface. Had the LM achieved an orbit with an apocynthion (high point) much less than...
...moon, Aldrin and Armstrong donned their space suits and crawled through a tunnel for a final checkout of the lunar module before its long separation from the command module. They paid particular attention to Eagle's propulsion systems?the tanks containing the hypergolic fuels that fire the descent and ascent engines, and the pressure gauges on the helium that forces the fuels into the combustion chambers, where they burn upon contact with one another. Efficient and businesslike, they completed the check 30 minutes ahead of schedule. Two minutes before the spacecraft disappeared behind the moon on its 13th revolution, Houston...
...Monday, after another 4-hr. sleep period sandwiched between two meals, Armstrong and Aldrin will fire the LM's ascent engine, using the four-legged descent stage as a launch pad. If all goes well, they will rendezvous with Collins and transfer to the command module, taking their precious rocks with them in sealed boxes and leaving the LM in orbit around the moon. From that point on, they will again follow the path of Apollo 10. After firing themselves into an earth-bound trajectory, they will splash down in the Pacific Ocean some 1,160 miles southwest of Hawaii...
...York in a record 66 days. Four of his countrymen are pushing their dog sleds toward Spitsbergen, Norway, in the last days of a 16-month, 2,000-mile trek across the Arctic. This summer, eight men from East Africa will try to follow up their successful ascent of Mount Kilimanjaro (elevation: 19,340 ft.) by climbing Mount Everest (29,028 ft.); all are blind. Stunt Man Evel Knievel plans to race a jet-powered motorcycle down a ramp at 280 m.p.h. and-God and the authorities willing-jump across the Grand Canyon. Last week Henry Carr, Detroit Lions defensive...
