Detailed explanation-1: -NASA satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice.
Detailed explanation-2: -The data from these satellites are used for several applications covering agriculture, water resources, urban planning, rural development, mineral prospecting, environment, forestry, ocean resources and disaster management.
Detailed explanation-3: -Satellites provide in-flight phone communications on airplanes, and are often the main conduit of voice communication for rural areas and areas where phone lines are damaged after a disaster. Satellites also provide the primary timing source for cell phones and pagers.
Detailed explanation-4: -The Earth observation satellites ERS-1, ERS-2 and Envisat of European Space Agency as well as the MetOp spacecraft of EUMETSAT are all operated at altitudes of about 800 km (500 mi). The Proba-1, Proba-2 and SMOS spacecraft of European Space Agency are observing the Earth from an altitude of about 700 km (430 mi).
Detailed explanation-5: -A geostationary orbit allows satellites to continually monitor a particular region uninterrupted. Satellites in a low earth orbit can directly monitor the climate from their position within or just above the atmosphere, and can provide near-global coverage as they scan over different swathes of ground with each orbit.
Detailed explanation-6: -They are used for weather forecasting. They are used for transmitting TV and radio signals. They are also used for remote sensing and telecommunications. They are used in GPS (Global Positioning System). They collect information about outer. planets. meteorites. stars.
Detailed explanation-7: -They are used in communication. They are used in weather forecasting system. They are used in GPS (Global Positioning System) They are used to transport instruments and passengers to the space to perform experiments.
