Abstract

The Next Generation Space Telescope (NGST) is currently being designed during a pre-phase A study in cooperation with the NASA Goddard Space Flight Center (GSFC) led team. Ball Aerospace and Technologies Corporation is leading one of two competitive GSFC funded pre-phase A studies of mission architectures for NGST. The NGST is the next major NASA astronomy mission following HST and SIRTF. NGST will be an observatory providing zodiacal light background limited 1-5 micron imagery and spectroscopy using a passively cooled 6 to 8 meter diameter telescope. The stretch goals specify imagery and spectroscopy in the 5 to 30 micron region and shortward of 1 micron. While emphasizing science return and maintaining simplicity, we have arrived at a configuration of a highly reliable mission architecture that achieves the desired science including many of the stretch science goals. This paper will describe the process and major trades we used to arrive at the system configuration, our current configuration and some of the key remaining trade-offs.
