Collection Item Summary:
This United States one dollar bill is a memento of Apollo 9, an Earth orbital flight of the lunar module made in March 1969 during the Apollo program. As part of the official process of certifying the flight, before human spaceflights, the National Aeronautic Association (NAA) had the astronauts or others autograph dollar bills, witnessed by the NAA official for the flight (who sometimes also signed the bill). The bills were then placed aboard the spacecraft. After the mission, recovering the identifiable bills served "as the basis for certification of the identity of the astronauts on each of the flights." James A. McDivitt, David Scott, and Russell Schweickhart signed the front of this bill.
The NASA Johnson Space Center transferred this bill to the National Air and Space Museum in 1976.
