![]() ![]() Much of modern Western civilization is derived in one way or another from the ideas of the ancient Greeks and Romans, and this is true in astronomy as well. Let us now look briefly back into history. Describe early examples of astronomy around the world.By the end of this section, you will be able to: "Aqua Earth-observing satellite mission".

San Francisco, California: Wikimedia Foundation, Inc. Aqua’s orbit ascends from south to north during the daylight hours, crosses near the North Pole, circles around Earth’s nighttime side, and crosses near the South Pole to return to the daytime side." "Aqua follows a kind of polar orbit known as a Sun-synchronous orbit, which means it crosses the equator at the same local time during each pass. The sixth Aqua instrument, HSB, collected approximately nine months of high quality data but failed in February 2003." "It continues transmitting high-quality data from four of its six instruments, AIRS, AMSU, CERES, and MODIS, and reduced quality data from a fifth instrument, AMSR-E. Additional variables also being measured by Aqua include radiative energy fluxes, aerosols, vegetation cover on the land, phytoplankton and dissolved organic matter in the oceans, and air, land, and water temperatures." "Aqua is a NASA Earth Science satellite mission named for the large amount of information that the mission is collecting about the Earth's water cycle, including evaporation from the oceans, water vapor in the atmosphere, clouds, precipitation, soil moisture, sea ice, land ice, and snow cover on the land and ice. This image shows a Bonner Ball Neutron Detector which is housed inside the small plastic ball when the top is put back on. Lofting an observing system into an orbit around the Earth requires designing and testing for survival of the rocket trip upward and the orbiting technique (usually a second stage for orbital insertion). Global Positioning System (GPS) satellitesĭetector systems may be launched for extended periods either for suborbital Earth astronomy or Earth-orbit astronomy. The green dashed line is the 20,230 km orbit used for Global Positioning System (GPS) satellites. In the diagram on the left, the black dashed line is the geosynchronous orbit.
