A photo of the NASA Langley Impact Dynamics Gantry Facility with Pointers to the Amateur Radio Antennas and Associated Frequencies of Each System.

The Impact Dynamics Research Facility (IDRF) shown in the picture above was originally known as the Lunar Landing Research Facility (LLRF) in the 1960s. This was one of the locations where NASA utilized tethered landers to train the Apollo astronauts for moon landings. If you visit the image links below you will learn that this facilty has a rich and varied history. The LLRF is one of several National Historic Landmarks at NASA Langley Research Center.
