To commemorate the 25th anniversary of the first Apollo landing, Stonehenge Ltd., is introducing "The Molecular Expressions^TM Moon Rock Collection." These limited edition ties recreate the molecular structures of actual lunar samples -- lunar lava, lunar soil, lunar breccia and meteorites -- collected during Apollo missions 11, 12, 14, 15, 16 and 17. The colors and patterns on the ties are based on the photo-micrographs (photographs taken through a microscope) of Florida State University research scientist, Michael Davidson.

Apollo 12 - Astronauts Alan Bean and Pete Conrad landed the lunar module Intrepid in the Ocean of Storms just 700 feet away from the unmanned Surveyor 3 lander. Apollo 12 astronauts collected 75 pounds of rocks and a camera from the Surveyor during their 32 hour stay on the Moon.

Apollo 14 - Alan Shepard, the first American in space during the Mercury missions, landed in the Fra Mauro region of the Moon with Edgar Mitchell. After collecting 98 pounds of Moon rocks with the help of a lunar 'wheelbarrow', Shepard launched a golf ball on the surface using a makeshift club.

Apollo 15 - Apollo 15 astronauts Jim Irwin and David Scott landed in the Hadley Rille on the lunar surface in the Lunar Lander 'Falcon'. This was the first mission to deploy the Lunar Rover, an electrically-powered jeep that allowed astronauts to explore a larger portion of the landing site and collect 173 pounds of Moon rocks and soil samples.

Apollo 16 - Apollo 16 astronauts Charles Duke and John Young landed the Lunar Lander 'Orion' in the Descartes plains region of the Moon. During their 20 hours of exploration using the second Lunar Rover, the astronauts collected 213 pounds of Moon rocks and soil samples.

Meteorites - Before exploring the Moon, meteorites were the only extraterrestrial samples ever examined by scientists. There are a large variety of meteorites that originate from nearly every planet in the solar system.
