Site of Former RL10 Test Stand

Marshall Space Flight Center once had a test stand suitable for altitude-testing RL10 rocket engines. It was Building 4710, or the "Liquid Hydrogen Familiarization Facility."

It seems that the RL10 test stand is completely gone: None of the buildings appear to remain, and (looking at the aerial view) the asphalt bears no scars which might hold clues to location's former use (although it appears that a cluster of high-pressure gas cylinders remain). The facility was surrounded by a comma-shaped berm, which also remains to this day (although it is heavily overgrown with trees).

Today Buildings 4745 and 4745-1, comprising the sandblast facility, are located on the site.
