A joint resolution authorizing establishment of a memorial to honor America's astronauts.

Authorizes the L-5 Society to establish a memorial on Federal land in the District of Columbia or its environs to honor America's astronauts, especially those astronauts who gave their lives in pursuit of knowledge for all mankind.

Requires the L-5 Society to select, subject to the approval of the Commission of Fine Arts and the National Capital Planning Commission, the site, design, and plans for the memorial. Terminates the authority to establish the memorial if its construction is not begun within five years with non-Federal funds sufficient to ensure its completion.
