In November 2003, ASEB released a report, An Assessment of NASA s Aeronautics Technology Programs. After the release, NASA requested the NRC to reconvene the Panel on Vehicle Systems Program, which had been established as part of the study infrastructure for the report. Specifically, NASA wanted an evaluation of the progress made by the Program in formulating and directing its activities over the past nine months (since March 2003). This letter report presents the findings of that review. In almost all cases, the recommendations contained in this letter report, amplify and reinforce those contained in the full report.
