Space Projects, Status and Remaining Challenges of the Advanced X-ray Astrophysics Facility
Abstract
As requested, we reviewed the National Aeronautics and Space Administration's (NASA) Advanced X-ray Astrophysics Facility (AXAF) program in terms of its phased development status. Our objectives were to assess (1) program cost and schedule status, (2) results of tests of the observatory's outer mirrors, and (3) remaining technical challenges. Although the information contained in this report is current, subsequent to commenting on the report, NASA instructed the AXAF development contractor to study options for reducing program costs. One option being studied is a redesign of the observatory that includes fewer mirrors and science instruments and launch on an expendable launch vehicle. If adopted, such a redesign would impact the observatory's cost, schedule, and performance. NASA does not expect to make a decision on the options before late March 1992.
