摘要:
Scientists working on NASA's Earth Observing System (EOS) are now considering a new set of instruments for the global monitoring program and debating the order in which these should fly.“In this time of uncertain budgets, what we have to do as a scientific community is to prioritize our measurements,” said Jeff Dozier, EOS project scientist, at a NASA press workshop September 12. “This allows us to give to the Congress and the administration a program they can buy by the

摘要:
It looks as though the United States will avoid the crisis situation of a gap in weather data resulting from the aging GOES‐7 satellite and technical problems with the next generation of weather satellites (GOESNEXT). Officials at the National Oceanic and Atmospheric Administration, which oversees the National Weather Service, recently announced their decision to borrow at least one and possibly several European satellites until the GOES‐NEXT program gets off the ground.The GOES (Geostationary Operational Environmental Satellites) series is currently 3 years behind schedule and $500 million over budget. Problems with its complex design, program management by both NOAA and the National Aeronautics and Space Administration and poor performance by the contractor led Department of Commerce Secretary Robert Mosbacher to slow down the GOES‐NEXT series to ensure that it is built

摘要:
Arctic marine geologists were a strong presence in the small city of Tromso, Norway, this summer. Scientific parties and crews for three icebreaker research vessels were joined by representatives of the scientific and executive committees of the Nansen Arctic Drilling (NAD) Program. As many of the world's leading Arctic scientists gathered, preparations were made for what some consider to be the most ambitious scientific expedition to the North Pole ever. Arctic '91, a six‐nation research expedition in the Barents and Laptev Seas north of the Soviet Union, will collect valuable data for studies of global warmin

摘要:
Planetary Mappingis a wonderful find for both the researchers who use the planetary and satellite maps and for historians of planetary exploration.Planetary cartography—the art and science of making maps of the moon, planets, and their satellites—represents a crucial step in the exploration of the solar system. Without detailed and accurate maps, the scientific objectives for orbiter missions such as Magellan (now in orbit around Venus) and Galileo (en route to Jupiter) could not be planned in detail, nor could surface landers such as Apollo (Moon) and Viking (Mars) be directed accurately to their chosen targets. For the last 500 years, the exploration of our own planet has depended vitally on the availability of detailed maps of the oceans and New World. Today much pioneering planetary exploration depends on similar types of maps generated not from ground surveys or air photography, but from data obtained by robot and manned missions using both digital and film camera syst
