L i k e T h e M o o n It was on October 4, 1957, that the first man-made object ever achieved orbit around Earth in outer space. The Russian satellite Sputnik was designed to measure and transmit information about the density of the upper atmosphere as it circled the Earth. Before then, all atmospheric information that meteorologists had was based on "looking up" instead of "looking down." Since Sputnik, the science of satellites has advanced significantly. Specialized satellites now orbit the Earth for telecommunications, global broadcasting, oceanic observations, scientific research, and military purposes, as well as for atmospheric observation. It's amazing to consider the rapid progress and evolution of satellite technology. Meteorological satellites themselves have changed considerably since Sputnik. Weather observation and forecasting has become much more reliable today, thanks to the sophisticated satellites currently orbiting Earth.

But here in Boston, at the annual meeting of the American Association for the Advancement of Science, researchers focused on spacecraft that are still on the job, sending back data for peaceful purposes rather than military advantage.

SATELLITES OF THE OUTER PLANETS The satellites of the giant outer planets are a surprisingly diverse group of bodies. Most are composed of mixtures of water and other ices, including most likely ammonia ice, and rocky material. An amazing variety of unusual and spectacular geologic features are observed on these satellites, including active volcanism on two of them, which are illustrated on these pages. Also discussed are some of the processes that form them and the important issues they raise for geologists. Click on each image to view at full resolution or to access individual Web pages. A few of these images are stereo (three-dimensional) images, which are highlighted by the stereo symbol. Additional 3-D images of the satellites are available on the 3-D Tour of the Solar System The Galilean Satellites The four large Galilean Satellites of Jupiter (from left to right in mosaic Io Europa Ganymede , and Callisto ) resemble a miniature solar system. The global density, relative amount of rocky material, and duration and intensity of geologic activity on each satellite all decrease with increasing distance from Jupiter. Each satellite is very distinctive in appearance and geologic history. Io, the densest and innermost major satellite, is volcanically active today. Europa has a highly fractured, young icy outer shell. Ganymede has a complex volcanic and tectonic history, and Callisto, the least dense and outermost satellite, is heavily cratered and rather bland by comparison. The geologic histories of these satellites are related to tidal deformation and heating, which is more intense closer to Jupiter.

welcome to wildwildweather.com Geosynchronous Weather Satellite Coverage to Limb Satellites have made weather forecasts much more accurate than they were when your parents were little. They allow Meteorologists to track weather systems from far out in the ocean where no one is, and they let us see the BIG picture all at once. They do more than just give us a look at where the clouds are, they can measure the temperature of the ground, the clouds, and water. The satellite pictures you see on TV each night are usually from the GOES 8and GOES 9 spacecraft. GOES stands for Geostationary Operational Environmental Satellite What does Geo-stationary mean ? A Geo-stationary satellite is very very high... much higher than the Space Shuttle goes when astronauts go into orbit. The Shuttle can go about 500 kilometers high. The GOES satellite is over 35,000 kilometers above the Earth. At this height, it takes the satellite about 24 hours to go around the Earth... but, since the Earth itself turns around once each 24 hours, the satellite is always over the same spot! That's why we call it Geo (Earth) Stationary (not moving) Satellites and Orbits: an Introduction by the Integrated Program Office Outreach Team.

60. The Galileo Project | Science | Satellites Of Jupiter Introductory information, focusing on discovery, history and naming. http://galileo.rice.edu/sci/observations/jupiter_satellites.html

The Galileo Project Science Satellites of Jupiter Jupiter's moons Satellites of Jupiter Jupiter has a large number of satellites. Of these, four are comparable to the Earth's Moon in size; the rest are orders of magnitude smaller. When Jupiter is at opposition and closest to the Earth, the stellar magnitude of its four large moons is between 5 and 6. This means that, were it not for the shielding brightness of Jupiter, these bodies would be visible with the naked eye. The aperture of the telescope used by Galileo in 1610 and its magnification thus brought these four "Galilean" satellites within his grasp. But first Galileo had to make adjustments to the instruments. When viewing bodies that are very bright and very small, the optical defects of the telescope can be crippling. By trial and error Galileo learned to stop down the aperture of his instrument until he could begin to make useful observations. At the end of 1609, as he was finishing his series of observations of the Moon , Jupiter was at opposition and the brightest object in the evening sky (not counting the Moon). When he had made the new adjustment to his instrument, he turned his attention to Jupiter. On 7 January 1610 he observed the planet and saw what he thought were three fixed stars near it, strung out on a line through the planet. This formation caught his attention, and he returned to it the following evening.
