...Clinton evaluate these plans recommended strongly that the space station go into a high-inclination orbit so that Russian spacecraft can visit from the Baikonur spaceport and perhaps perform rescue operations. Even that, however, might be too much for our partners. Launching at high inclinations reduces the shuttle's payload because the rockets get less of a boost from the earth's rotation; as a result, the Japanese and European modules may be too heavy to get into orbit...
...combination of the antibody, acting as a guidance system that homes in on tumor cells, and doxorubicin, as the lethal payload, knocked out many kinds of advanced cancer in mice, including colon, lung and breast tumors that had spread to other organs. In earlier animal experiments, researchers were able to cure only those cancers that had not been growing very long or that had not metastasized. "One of the problems that have held back the field for a long time is that we were never sure that well-established solid tumors could be eliminated," says Dr. David Scheinberg, chief...
...interested in Timberwind? The reasons date back to the early 1970s, when NASA, with the Pentagon's blessing, decided to put the bulk of its research funds into the reusable space shuttle. Further development of conventional rocket boosters stalled. Now both agencies find themselves bumping into the limited payload capacities of the remaining rockets; NASA for hoisting its space station into orbit and the Pentagon for lifting its big directed-beam Star Wars weapons. The proposed nuclear-powered rockets would more than triple the payload of the U.S.'s most powerful booster, the Titan 4, from 20 tons to more...
...notoriously inaccurate. Iraq is believed to have 25 of the advanced Soviet-made warplanes, which can make the round trip to Tel Aviv without refueling and which boast terrain-hugging radar. If even a single SU-24 slips through Israel's defenses, it can deliver a seven-ton payload with pinpoint accuracy. By comparison, each stripped-down Scud can pack only 662 lbs. of conventional explosives or 331 lbs. of chemical weapons...
...Aerospatiale of France said they will spend $36 million over the next five years to study the feasibility of a second-generation supersonic jetliner. It is a high-flying ambition. The current Concorde, operated by British Airways and Air France, has a range of 4,000 miles and a payload of just 100 passengers. Concorde II would fly twice the distance carrying as many as 300 passengers. The new plane would streak through the stratosphere at Mach 2.5 (2 1/2 times the speed of sound, or about 1,875 m.p.h., in contrast to the current model's Mach...
