      This spacecraft 
        was the first of the Apollo series to successfully orbit the moon, and 
        the first manned spacecraft to leave Earth's gravity and reach the Moon. 
       
      The mission 
        provided operational experience and tested the Apollo command module systems, 
        including communications, tracking, and life-support, in cis-lunar space 
        and lunar orbit, and allowed evaluation of crew performance on a lunar 
        orbiting mission. 
      The crew 
        photographed the lunar surface, both farside and nearside, obtaining information 
        on topography and landmarks as well as other scientific information necessary 
        for future Apollo landings. Additionally, six live television transmission 
        sessions were done by the crew during the mission, including the famous 
        Christmas Eve broadcast in which the astronauts read from the book of 
        Genesis. 
      All systems 
        operated within allowable parameters and all objectives of the mission 
        were achieved.
