NASA is developing the Advanced X-ray Astrophysics Facility (AXAF) to be one of the mainstays of this nation's space science program during the next decade. It is to be used to investigate important questions such as the age and origin of the universe. The status of the 1992 redesigned AXAF program is reviewed to assess the reasonableness of NASA's estimate of program costs and to determine the extent to which the redesign will provide scientific returns comparable to the original program. It is recognized that a recent congressional direction may affect a portion of this program, but the cost and technical impacts of that decision are uncertain at this time. However, the results of the work in other segments of the program are still relevant.
