The Spacecraft Propulsion Research Facility at Plum Brook Station in Sandusky, Ohio is the world's largest space simulation chamber measuring 100 feet in diameter and rocketing more than six stories tall.

The facility conducts tests within the vacuum chamber after the necessary electrical power, fuel, oxidizer, and purge gas connections are made. To recreate the conditions of outer space while still on earth, the test facilities rely on vacuum pumps and cryogenic systems which can simulate deep space temperatures down to -423°F. Protecting the scientists and engineers is critical to moving space missions forward safely.

Programmable Logic Controllers are used in conjunction with the SCADA and historian software to control and log all events of the test firing from the start of the water deluge system until the completion of the engine test firing and facility shutdown. WIN-911 delivers critical alarm information via voice callout along with email and paging notifications to NASA engineers during the test procedure.
