When Soyuz 16 landed safely on the snow-covered steppes of Kazakhstan last week after six days in orbit, Soviet space officials were exultant. The successful flight, they said, showed that their cosmonauts and spacecraft were capable of carrying out their assigned role in next July's historic orbital linkup of an American Apollo and Soviet Soyuz...
More than half a billion miles from earth this week, a small (570 Ibs.), unmanned spacecraft is completing the first lap of an incredible journey. As it hurtles past Jupiter at a speed of 107,000 m.p.h., some 50 times faster than a rifle bullet, Pioneer 11 is slated to use its cameras and instruments to reconnoiter the solar system's largest planet. That will be only part of its task. As it passes 26,000 miles above Jupiter's turbulent cloudtops, the spacecraft will be pulled by the planet's gravitational field into a corkscrew-shaped...
...planned flyby of Jupiter should be changed into a two-for-one mission that would include Saturn. NASA had just scuttled its even more ambitious "grand tours," which would have taken advantage of the alignment of the outer planets in the late 1970s to send, for example, a single spacecraft past Jupiter, Uranus and Neptune, using the gravity of one planet to fling the ship toward the next. But Van Allen stubbornly refused to give up. At his suggestion, imaginative "back-room" trajectory experts at Pasadena's Jet Propulsion Laboratory showed that a corkscrew turn could get Pioneer...
Jigsaw Puzzle. Since that momentous discovery, Van Allen, now 60, has quietly continued his contributions to the exploration of space, designing instruments for 20 spacecraft, including a particle counter for the current Pioneer...
...trying to win approval of a two-planet flight that would be launched in 1979 to send a single spacecraft past Jupiter and Uranus. He is also trying to whip up enthusiasm for a ship that would go into orbit around Jupiter, monitoring the planet up to three years...
