NASA: Lessons from Ongoing Major Projects Can Inform Management of Future Space Telescopes, Statement of W. William Russell, Director, Contracting and National Security Acquisitions, Testimony Before the Subcommittees on Space and Aeronautics and Research and Technology, Committee on Science, Space, and Technology, House of Representatives [open pdf - 1MB]
From the Highlights: "The projects in NASA's current portfolio of major space telescopes-- JWST [James Webb Space Telescope], Roman [Nancy Grace Roman Space Telescope], and SPHEREx [Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer]--have roots in past decadal surveys on Astronomy and Astrophysics from the National Academies of Sciences, Engineering, and Medicine. NASA is now considering the results of the National Academies' 2020 decadal survey, which may spur new projects in this portfolio. NASA has made improvements in acquisition management in recent years, but it remains a long-standing challenge for the agency. This statement reflects GAO [Government Accountability Office]'s observations on (1) the current status of NASA's major telescope projects, and (2) lessons learned that can be applied to NASA's management of its future telescope projects as it considers the results of this decadal study."
