It covered human spaceflight options after the time NASA had planned to retire the Space Shuttle.[1][2][3] A summary report[4] was provided to the OSTP Director John Holdren, White House Office of Science and Technology Policy (OSTP), and NASA Administrator on September 8, 2009.[5] The estimated cost associated with the review was expected to be US$3 million. The committee was scheduled to be active for 180 days;[6] the report was released on October 22, 2009.[7]
