Key Terra Facts Joint with Japan and Canada Orbit: Type: Near-polar, sun-synchronous Equatorial Crossing: 10:30 a.m. Altitude: 705 km Inclination: 98.1° Period: 98.88 minutes Repeat Cycle: 16 days Dimensions: 2.7 m × 3.3 m × 6.8 m Mass: 5,190 kg Power: 2,530 W Design Life: 6 years Terra URL terra.nasa.gov. Aura, along with Terra (launched Decem-ber 1999) and Aqua (launched May 2002), provides an unprecedented view of the global Earth system. two infrared bands and a thermal infrared band). ASTER has a 60-km swath width, with a cross-track adjustable swath center. Terra’s five instruments produce 83 core data products which are distributed through the Land Processes Distributed Active Archive Center (LPDAAC), the Atmospheric Science Data Center (ASDC), Ocean Color Web, Level 1 and Atmosphere Archive and Distribution System, and the National Snow and Ice Data Center (NSIDC). For example, carbon dioxide levels have risen 30 percent since the industrial revolution and about 40 percent of the world's land surface has been transformed by humans.Physically, the EOS Terra spacecraft is roughly the size of a small school bus. The single Terra data record now stretches beyond 20 years. Natural geological forces have been rearranging the surface features and climatic conditions of our planet since its beginning. Global observations from the Terra satellite. Livestock herds and biomass burning are sources of methane, which is a greenhouse gass with thirty times the heat-trapping capacity of carbon dioxide. 26-30 Satellite Facts.
Terra Quick Facts The Terra spacecraft consists of a spacecraft platform provided under a NASA contract with Lockheed Martin Missiles and Space, Valley Forge, Pa., and five instruments procured under a NASA contract with several U.S. and international corporations. Here are 35 interesting satellite facts. What are the causes and affects of ozone fluctuations? NASA has 2 satellites chasing each other around the Earth tracking the distance between them to measure gravitational anomalies. Consequently, NASA's Earth Science Enterprise has begun an international study of planet Earth that is comprised of three main components: 1) an Earth Observing System (EOS), consisting of a fleet of satellites specially designed to study the complexities of global change; 2) an advanced computer network for processing, storing, and distributing data (called EOSDIS); and 3) teams of scientists all over the world who will study the data.The five Terra onboard sensors are (see animations at right): Terra carries five state-of-the-art sensors that have been studying the interactions among the Earth's atmosphere, lands, oceans, and radiant energy. Terra has been collecting data about Earth's changing climate. Track TERRA Satellite in Real Time Detailed information about TERRA satellite Designator id: 1999-068A Description of TERRA Satellite: The Earth Observing System (EOS) is a science and observation program that will provide long-term (15-year) data sets for Earth system science in order to gain an understanding of the interactions between Earth's land, atmosphere, oceans, and biology.
