Test Stands at Stennis Space Center, 1960s
The B-1/B-2 Test Stand is a dual-position, vertical, static-firing structure built at NASA's John C. Stennis Space Center in the 1960s. First stages of the Apollo Saturn V rocket were tested on the stand from 1967 to 1970. Stennis now leases the B-1 test position to Pratt & Whitney Rocketdyne for testing of RS-68 engines. It is preparing the B-2 test position to test the core stage of NASA's Space Launch System in late 2016 and early 2017. The SLS stage, with four RS-25 rocket engines, will be installed on the stand for propellant fill and drain testing and two hot-fire tests.
