...three-man moon crew had been aboard, they would still have been safe enough. The makeshift maneuvers successfully inserted the third stage and the unmanned Apollo 6 spacecraft into a 218-mile by 113-mile elliptical orbit (instead of the planned 115-mile circular orbit). But there was more trouble to come...
...third-stage engine to restart-in an effort to shove it from its parking orbit to a distance of 320,000 miles on a simulated moon trip- nothing happened. Still attempting to salvage the mission, the controllers next separated Apollo 6 from the dead third stage and used the spacecraft's engine to push it to an altitude of 13 822 miles. From that height, it plunged back into the atmosphere and parachuted to a safe landing and recovery in the Pacific Ocean. Later, NASA reported the orbiting third stage mysteriously broke into "thousands of pieces...
...Atrato River for the location of dams. Eventually, in addition to a role in mineral exploration, the projectiles may be used to find water, to place deep-sea anchors, and to bury radioactive fuels re-entering the atmosphere after the flights of nuclear rockets. Shot from unmanned spacecraft orbiting distant planets, one Sandia scientist proposes, the projectile probes could even help determine if there are water tables beneath the surface of Mars and Venus...
Secrecy was again the order of the day at week's end when Johnson flew out of Washington, his destination unrevealed until shortly before he boarded Air Force One. The first stop was Houston, where the President toured the Manned Spacecraft Center. Next, he dropped in at Beaumont, Texas, for a fund-raising dinner, then on to Marietta, Ga., to watch Lockheed Aircraft roll out the world's largest aircraft, the C-5A Galaxy flying freighter (wing span: 223 ft., height: 65 ft.), which can lift 21 times more cargo than any current U.S. air transport. "This would...
...Pickering, 57, head of Caltech's Jet Propulsion Laboratory, it has been a zingy decade-notably in the space race with Russia. Pickering's box score: 500 satellites, 13 successful moon missions, 2,000 hours of manned flight and twelve hours of human excursion outside a spacecraft for the U.S., v. 250 satellites, eight moon shots, 530 hours of manned flight and 20 minutes outside a spacecraft for the Soviets...
