Why it's listed
Built at NASA's Plum Brook Station near Sandusky, Ohio, this test complex was designed to hot-fire full-size space vehicles in conditions simulating an orbital altitude of 100 miles. Its test building rises more than 70 feet above ground and extends 176 feet below grade. A stainless steel vacuum chamber holds vehicles up to 22 feet in diameter and 50 feet high. A liquid hydrogen cold wall chilled to -320°F simulates the heat sink of space, while quartz infrared lamps reproduce solar heat. Steam ejectors and a large water spray system remove and cool engine exhaust. The facility matters because it is the only one in NASA's inventory able to fire a large rocket under simulated vacuum, cryogenic temperature and thermal radiation. That capability was central to developing the Centaur upper-stage rocket, which later launched the Pioneer, Viking and Voyager spacecraft. NASA currently keeps the facility on standby status.
Significance in brief: The nomination argues the facility is the only one in NASA's inventory able to hot-fire a large rocket while simulating the vacuum, cryogenic cold and solar thermal radiation of space. This capability was crucial to developing the Centaur upper-stage rocket, which launched probes such as Pioneer, Viking and Voyager. Data from Centaur engine test firings here contributed greatly to that program's success.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
