NASA Concludes WFIRST Space Telescope Preliminary Design Phase

A NASA-operated space observatory has passed the preliminary design review phase, marking a major milestone for the spacecraft's development, Space News reported Monday.

Michael New, deputy associate administrator for science at NASA’s Science Mission Directorate, said the Wide-Field Infrared Survey Telescope passed the PDR phase with successful results.

Work to convert WFIRST's primary mirror also exceeded performance expectations, New told the National Academies’ Space Studies Board during a meeting last Wednesday.

The space agency announced the telescope's PDR completion in a tweet posted Nov. 1. WFIRST passed the PDR despite a lack of funds, with Congress allotting more budget for the James Webb Space Telescope.

NASA plans to launch WFIRST within the 2020s.

The Enhanced Polar System Recapitalization program would deliver eXtended Data Rate payloads that would operate in the region until USAF gets access to polar variants of protected and evolved satcom technology in the 2030s, Los Angeles AF Base said Monday.
