Green Bank ‘digs’ beneath moon’s surface

Green Bank’s National Radio Astronomy in West Virginia has been “digging” up to 50 feet below the moon’s surface to reveal more than can be seen with the naked eye.

Radio beams from the Arecibo Observatory in Puerto Rico rebound to the Green Bank telescope, the world’s largest fully steerable radio telescope.

This observing technique, known as bistatic radar, also studies asteroids and other planets in our solar system.

The images include the Sea of Serenity near the Apollo 17 landing site. They help interpret the history of the moon, often obscured by billions of years of dust buildup, and aid future moon landings.

Green Bank is five miles east of Cass, where the Cass Railroad leaves for Bald Knob (4,843 elevation) with tourists aboard.
