...disease and stroke," says Associate Editor Peter Stoler, "but it's being conquered. There's no question that if you get treatment you can live a lot longer." For the story, Stoler and Reporter-Researcher Jean Bergerud, a veteran of 22 years in the Medicine section, interviewed pioneer blood-pressure researcher Dr. John Laragh, our cover subject, and pored over such weighty medical tomes as Laragh's 900-page Hypertension Manual. Notes Senior Editor Leon Jaroff, who edited the story: "Hypertension sounds like a disease of nervous, high-strung individuals. Many people are embarrassed to admit that...
...past few years, robot spacecraft have surveyed the planet Mars in exquisite detail, sent back the first closeup pictures of Venus and Mercury, and penetrated the powerful radiation belts surrounding the sun's largest satellite, Jupiter. Now, after sweeping even closer to Jupiter than did its predecessor, Pioneer 10, last December, Pioneer 11 is beginning the long trip to its next target: Saturn...
...solar system will take five years, but flight planners at NASA'S Ames Research Center have every reason to expect the 570-lb. nuclear-powered robot to survive the trip. If it does, it will send back closeup pictures and other data from the ringed planet. Of four Pioneers that were launched into solar orbit between 1965 and 1968 to monitor interplanetary space, all are still transmitting scientific data-even though they were designed by Pioneer's prime contractor, TRW Inc., to last only six months; only one is experiencing some difficulty with a solar sensor. Signals...
Kamikaze Mission. Pioneer ll's longevity will be threatened in September 1979, when it swoops between Saturn and the innermost of its three rings on what Wolfe admits could be a "kamikaze mission." The spacecraft could be knocked out of action in a collision with a chunk of the ring's icy debris, some of which may be up to half a mile across. Otherwise, it will pass as close as 1,850 miles from Saturn's cloud tops (compared with 26,725 miles from Jupiter's). It will then be whipped around Saturn...
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...
