          On 20 July 1969, Neil Armstrong became the first
        
        
          person to walk on the surface of the moon. He was
        
        
          joined by Buzz Aldrin. A third astronaut,
        
        
          Mike Collins, remained in orbit with the
        
        
          command and service modules.

            What did they do?
          
        
        
          Armstrong and Aldrin
        
        
          spent almost 22 hours
        
        
          on the moon. About
        
        
          2.5 hours of this
        
        
          was spent outside
        
        
          the
        
        
          Eagle
        
        
          , collecting
        
        
          rock and soil samples,
        
        
          setting up experiments,
        
        
          and taking pictures.
        
        
          
            What was it like?
          
        
        
          Buzz Aldrin described
        
        
          the moon’s surface
        
        
          as like nothing on
        
        
          Earth. He said it
        
        
          consisted of a fine,
        
        
          talcum-powder-like
        
        
          dust, strewn with
        
        
          pebbles and rocks.
