NASA/HQ is hereby soliciting information about potential sources to provide support for study and report on radiation standards for lunar sortie missions. This will consist of an Ad Hoc committee to perform an independent assessment of the program's technical quality, relevance to exploration objectives, and effectiveness in maturing and infusing technologies. This work will assist the Government in overseeing the Constellation, human research, exploration technology development and lunar precursor robotic programs as well as the Commercial Orbital Transportation Services Project.
