...first missile ever scheduled to leave the solar system. "During high school years," Wilhelm says, "T used to haul an antique, three-inch brass reflector telescope through the attic to the roof of our St. Petersburg, Fla., home to look at Jupiter and its satellites, rings of Saturn and other celestialities." Although he was turned down for summer employment at Princeton's observatory after being asked one question - about his calculus grades - Wilhelm later became TIME'S science correspondent in Washington, D.C. Now in the Los Angeles bureau, Wilhelm has frequently turned his attention heavenward while following Apollo...
...downward force on tendons connected to the upper part of the hind legs. That launches the flea into the air. In fact, lift-off occurs so rapidly that the flea reaches peak acceleration of 140 Gs - more than 30 times that endured by astronauts during the launch of the Saturn 5 moon rocket...
...Saturn 1-B rocket lifted from its launch pad into the air above Cape Canaveral, Fla., and remained visible for miles downrange last week as it carried three rookie astronauts toward their rendezvous with the Skylab space station orbiting some 270 miles above the earth. The third and final Skylab mission was launched. The unprecedented stay in space may last as long as 84 days and will encompass the Skylab project's most ambitious undertakings...
...while the Skylab mission seemed to be in trouble. Only four days before the Nov. 10 launch date, workmen at the Kennedy Space Center discovered hairline cracks around bolts on all eight stabilizing fins of the Saturn 1-B booster that is to launch the ferry ship toward a rendezvous with the orbiting space station. The cracks may have developed when the rocket's fuel tanks were filled, enormously increasing the weight on the fins. Exposed to Florida's salty air, the fins may have been weakened by corrosion. To avert a calamitous accident after liftoff, NASA officials...
...launch a flyby of Venus and Mercury. In 1974 and 1976, with the help of European scientists, it will send Helios probes toward the sun. In 1977, as a substitute for its highly touted "grand tour" of the outer planets, it hopes to launch two flybys of Jupiter and Saturn. NASA's next probes of Mars will be in 1975, when two Viking softlanders will be launched-timed for a touchdown the following summer on the occasion of the 200th anniversary of American independence. Crammed with instruments-including color-TV cameras-the probes may finally answer...
