   Explanation: Bright sunlight glints as long dark shadows mark this
   image of the [5]surface of the Moon. It was taken [6]fifty-four years
   ago, July 20, 1969, by Apollo 11 astronaut [7]Neil Armstrong, the first
   to walk on the lunar surface. [8]Pictured is the mission's lunar
   module, the Eagle, and spacesuited lunar module pilot Buzz Aldrin.
   Aldrin is unfurling a long sheet of foil also known as the [9]Solar
   Wind Composition Experiment. Exposed facing the Sun, the foil trapped
   particles streaming outward in the solar wind, catching a sample of
   [10]material from the Sun itself. Along with moon rocks and lunar soil
   samples, the solar wind collector was returned for analysis in
   earthbound laboratories.
