Ironically, despite NASA'S concentration on solar research with Skylab, the agency's failure to anticipate the extent of sunspot activity during the vehicle's years in orbit contributed substantially to the craft's death. Russian scientists as well as America's own National Oceanic and Atmospheric Administration had predicted considerable solar disturbances, including great magnetic storms and solar flares. When they erupted in 1977 and 1978, they warmed the gases in the earth's outer atmosphere, increasing the drag on Skylab. Never fully powered because of its lost solar wing and failing batteries, the craft began to slip ever...
...methods of rescuing Skylab were considered by NASA and then discarded as impractical. There was talk of a joint Soviet-American mission, using the Soviet Soyuz system, but it had to be abandoned because the Russian craft's docking hardware was incompatible with Skylab's. Soyuz also lacked sufficient propellant to maneuver with the ailing U.S. vehicle and then give it a powerful boost into higher orbit. Declared NASA'S Frosch: "The obstacles involved were insurmountable, in the time remaining." Russian scientists, in effect, agree, although they note that if plans for a cooperative effort had been started two years...
...NASA engineers studied a plan to send a McDonnell Douglas F-15, America's hottest jet fighter, into a computer-guided supersonic climb to about 80,000 feet and then blast Skylab out of the sky with a non-nuclear rocket. This idea was dropped when the scientists concluded that Skylab would merely be blown into more pieces scattered over a wider area, increasing rather than reducing the danger of damage on earth...
...NASA has no intention of letting Apollo 11's birthday pass unnoticed. In Washington, Armstrong, Aldrin and their stay-in-orbit partner Michael Collins will be reunited for a round of ceremonies, capped by a replay of the original moon walk late at night at the Smithsonian's National Air and Space Museum. In Texas another old Apollo hand, Christopher Kraft, the director of the Lyndon B. Johnson Space Center, will preside at space-day ceremonies; he will open a temporary post office to cancel space-commemorative stamps for philatelists. At the Kennedy Space Center, a giant...
Continuing its program of manned space exploration, NASA also made ingenious use of castoff Apollo hardware to create Skylab. Despite a troubled beginning and now its embarrassing demise, the giant space station represented another great leap. In 1973, three teams of astronauts occupied the station in rapid succession, one remaining aloft for 84 days. That record was not beaten by the Russians until 1978. More important, it proved to all doubters-and there were many-that humans could live and work together in space for long periods, conquering both isolation and the physical effects of weightlessness, such as weakening...
