Jarred Astronauts. Failure of the third-stage rocket engine to restart later in the mission was tentatively traced to a broken line that supplied hydrogen to the ignition system. Without an ignition flame, the engine could not be restarted. To reduce the possibility of future breaks in the stainless-steel fuel lines, flexible joints in the lines will be either eliminated or greatly strengthened...
Mysterious Breakup. When controllers ordered the 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...
...greatly reduce the dangers of heart attacks - provided they are used in time. The electrocardiograph gives the physician a continuous moving pic ture of how the damaged heart is behaving. A simple oxygen system will do the patient's breathing for him. If his heart stops, electric paddles restart...
Though the Belfast doctors make a fetish of avoiding "haste or fuss," the patient is soon on his way to the hospital in the mobile unit, with his heart monitored all the way. If it stops en route, the doctors can restart it, just as they would in the hospital. The unit has proved so effective that in its first 15 months of operation not one of the 312 heart patients taken to the Royal Victoria has died in transit. Once in the hospital, many-perhaps most-of them have fared better because superior treatment was started so promptly...
With its tank vents still spewing tiny jets of gas, the slowly accelerating SIV B was then put through a simulated engine restart. Valves at the bottom of the tank opened, allowing liquid hydrogen to flow into the combustion chamber. Clearly visible on TV, the dwindling fuel hugged the bottom of the tank, its surface calm...
