...dramatic photographs that appear in these pages were taken by astronauts aboard U.S. space shuttles. The pictures provide clear evidence that the earth is in grave danger as a result of human activity. Overpopulation, pollution and energy consumption have created such planet-wide problems as massive deforestation, ozone depletion and the global warming that is believed to be caused by the greenhouse effect. Yet these alarming trends, and how they interact with such natural phenomena as hurricanes and volcanoes, are still not fully understood by scientists...
Major help in studying the earth's environment is expected to emerge from a project being planned by the National Aeronautics and Space Administration. Called Mission to Planet Earth, the program would consist of a series of satellite flights designed to monitor the earth with sensitive instruments that measure such vital signs as temperature, winds and atmospheric chemistry. These readings would add immensely to the knowledge gained from high- resolution photography alone. The object is to understand the planet's dynamics well enough to anticipate ecological disasters -- and find ways to forestall them. The project was suggested...
...Mission to Planet Earth would go a long way toward answering critics who have insisted that the U.S. space program has for years had no clear mission. If NASA gets the go-ahead, the project, which would cost an estimated $20 billion over the next two decades, could begin by 1996 with the launching of the first of a pair of 15-ton unmanned space platforms called the earth- observing system (EOS). Designed to operate for at least 15 years, the satellites would give scientists their first comprehensive look at just how the world's environment changes over time. Detectors...
...losing track of time. On Jan. 13 the 27-year-old Italian interior designer descended into a cave near Carlsbad, N. Mex., where she was to live for more than four months as part of an experiment aimed at examining how the stresses of long-term isolation could affect space $ travel. Pioneer Frontier Explorations, an Italian research foundation, had selected Follini, one of 20 volunteers for the assignment, because she was judged to have inner strength and stamina. For 131 days she dwelled alone in a 20-ft. by 12-ft. Plexiglas module sealed 30 ft. under the surface, without...
