NASA White Sands Test Facility (WSTF) in Las Cruces, New Mexico, founded July 6, 1963, is a self-contained NASA propulsion, materials and hazardous-systems testing facility. WSTF tests and analyzes rocket propulsion systems, oxygen systems, hypervelocity impacts, propellants and aerospace fluids, composite pressure systems, flight-acceptance hardware and spacecraft components; its work has supported human spaceflight from Apollo through the Space Shuttle and International Space Station. This is an access-controlled hazardous testing facility, not a general walk-in attraction: visits must be sponsored by a badged NASA employee, approved before arrival and may take up to 30 days to process. Visitors must present unexpired photo identification, complete the required safety review, consent to security inspection and follow site rules including long pants and sturdy closed footwear; additional prohibited-item and test-area controls apply.
