...most cost-effective method of advancing scientific research is to send spacecraft without astronauts off into different parts of the solar system, in a manner similar to the Voyager spacecraft. Because these spacecraft are inherently much less expensive, less complex and less risky than human-occupied craft, they provide more scientific returns per dollar investment...
...Voyager spacecraft were launched toward the outer reaches of the solar system. In addition to providing spectacular photographs of Jupiter and its moons, the Voyager spacecraft greatly expanded scientists' knowledge of the outer planets. Voyager 2 actually discovered a series of rings around Uranus...
...boosters. The U.S. orbiter is lifted by two recoverable solid rocket boosters and its own three main engines, a system designed exclusively for shuttle missions. Buran piggybacks on the l97-ft.-high Energia, the world's largest operational booster rocket -- a multipurpose powerhouse designed to lift shuttles or unmanned spacecraft weighing up to 100 tons. "Energia could be said to be a much smarter system than what we've got, since it could take anything up," says Seth Arenstein, editor of Soviet Aerospace magazine...
...Soviet Union's first reusable spacecraft orbited the Earth twice today and landed eight miles from its launch pad in Central Asia, marking the first unmanned space shuttle flight ever, a spokesperson for the National Aeronautics and Space Administration (NASA) said yesterday...
...week's end NASA's immediate job was clearly delineated: to complete Discovery's mission and bring it safely back to earth. Aboard the spacecraft, the astronauts attended to a few glitches, including a nagging problem in the craft's cooling system and a balky antenna on a communications instrument, which they managed to retract. They worked on science experiments, played tapes of classical and pop music and shot pictures of Pacific thunderstorms, of a lava flow in Ethiopia and of coastal erosion wreaked by Hurricane Gilbert in Yucatan...
