	EOS Homepage - Program Description
		Since its creation in 1958, NASA has been studying the Earth and its changing environment by observing the atmosphere, oceans, land, ice, and snow, and their influence on climate and weather.
		Phase I of the Earth Science Enterprise was comprised of focused, free-flying satellites, Space Shuttle missions, and various airborne and ground-based studies.
		It consists of a science component and a data system supporting a coordinated series of polar-orbiting and low-inclination satellites for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans.

	Teachers' Domain: Satellites Orbiting Earth
		Satellites in orbit around Earth are a fast and efficient way of gathering remotely sensed data about the planet as a whole.
		The main goals of the EOS program are to create a multi-disciplinary understanding of how the Earth system is changing and to advance knowledge about the components of the Earth system.
		This group of satellites traveling in formation in low polar orbit around Earth is sometimes referred to as the "A-train." Because their orbits are coordinated, the research data they offer benefits from simultaneous and sequential observations from a range of instruments.

		For complex Earth systems, listing the parts of system or organism with its various functions is no more adequate to understanding the complexity of a living thing than listing the parts of a submarine, Boeing 777 or Airbus 340 to understand how they function.
		One of the greatest accomplishments of the current systems, pioneered and advanced by the WMO, is the widespread trust that the general public has in weather forecasts.
		With your experience and established record of success in building observing systems, you have the ability and the mandate to play a key role and serve as a catalyst for this next level of achievement for the future of humankind.

	Earth Observing System (EOS) Pyroshock Separation
		The Earth Observing System (EOS) AM-1 spacecraft for NASA's Mission to Planet Earth is scheduled to be launched on an Atlas IIAS vehicle in June of 1998.
		One concern is that the instruments on the EOS spacecraft are sensitive to the shock-induced vibration produced when the spacecraft separates from the launch vehicle.
		Because of the unusually large amount of data acquired, Lewis developed a statistical methodology to predict the maximum expected shock levels at the interface between the EOS spacecraft and the launch vehicle.

		The impact of volcanoes on the Earth System was dramatically demonstrated in 1991 by the eruption of Mt. Pinatubo in the Philippines.
		The cold, snowy weather in New Zealand in late 1992, the severe storm damage caused by hurricanes such as Andrew and Iniki in the fall of 1992, and the heavy rains in the Midwest of the USA in the summer of 1993 have all been linked to the atmospheric effects of the eruption of Pinatubo.
		Examples are given of ground photographs of the eruption and the devastating pyroclastic flows and mud flows that were produced, the regional dispersal of the sulfur dioxide plume as measured by the Total Ozone Mapping Spectrometer (TOMS), Microwave Limb Sounder (MLS), and Stratospheric Aerosol and Gas Experiment II (SAGE II).
