Scientific paper

In 1996, three independent teams studied the feasibility of a large aperture space telescope to follow the Hubble Space Telescope. This report presents the findings of the three teams - TRW's NGST Study Team, Lockheed Martin's NGST Study Team, and Goddard Space Flight Center's NGST Study Team - and the technological roadmap which will guide to the successfull development of the NGST over the next decade. All three concepts share certain design features, including adjustable thin mirrors, deep space orbits, fast-steering mirrors for fine guidance, infrequent contact with the ground and a mass of about 2800 kg. They differ in the areas of mirror construction, materials and deployment, detector types, sunshield types, vibration control and launch vehicles. The observatory will allow astronomers to study the first protogalaxies, the first star clusters as they make their first generation of stars, and the first supernovae as they release heavy chemical elements into the interstellar gas. With its exceptional sensitivity and wide fields of view, it will let scientists study a range of topics, from interstellar chemistry to brown dwarf stars to potential planets around nearby stars.
