An Apollo-suited Manned Spacecraft Center technician as he deploys an Apollo Lunar Experiments Package on the moonscape at the Houston space center on July 15, 1966. The scientific instruments will be carried to the surface of the moon in a LEM similar to the mockup in the background. The scientific package weights about 170 pounds, but on the moon its weight is only about 30 pounds. (Photo by Ed Kolenovsky/AP Photo)
