...Miami, Fla., in a world of combustion engines, went on to log over 400 hours as a pilot herself, and has been driving fast cars since 1963. Single, a resident of New York City and a physicist, she was one of four women considered for astronaut status by NASA in 1965. She has competed in more than 120 recognized auto races; her most impressive wins were in the "Under 2 Liter Prototype" class at Sebring, Fla., in 1970 and in the "B Sedan" class in the 1973 North Atlantic Road Racing Championship...
Future Map. NASA, working through the Smithsonian Astrophysical Observatory, will aim high-powered pulses of laser light at the satellite from positions on the earth. By measuring the length of time the light needs to travel to the satellite and reflect to the laser stations, scientists will be able to calculate the exact distance from each laser gun to LAGEOS. Thus, by placing stations on each of the dozen or so tectonic plates that constitute the earth's surface, they can track the rate and direction of the plate movement, which results in continental drift. With stations on each...
...NASA scientists estimate that measurements made during the first four years of the program should be accurate to within four inches. But eventually, once the measurement techniques are perfected and more laser stations become operational, movements of the earth's surface as small as .4 in. per year, averaged over four years, will be detected...
Because LAGEOS is expected to remain in orbit for so long, NASA has placed aboard it two stainless-steel sheets, each etched with a message conceived by Astrophysicist Carl Sagan of Cornell University. Designed to inform extraterrestrial visitors or future inhabitants of the earth about the LAGEOS mission, the message shows three maps of the earth, depicting the continental drift that the satellite will help observe. The uppermost of the maps shows the continents as they are thought to have existed 225 million years ago, when Africa and South America were joined. The middle map is a picture...
...solar system, proved that Jupiter's tail is even longer. Pioneer's solar-wind gauges were shut down for at least 24 hours by a powerful magnetic field, indicating that the satellite was passing through the planet's tail. According to scientists at NASA'S Ames Research Center, Jupiter's tail must now be considered in planning any future space probes. The tail stretches for 430 million miles and spans the distance between the orbits of Jupiter and Saturn...
