NASA’s Stennis Space Center is considered by many as the finest hour in the
history of our center,” Stennis Propulsion Test Directorate Director Boyce

Engines, an external tank and a simulated aft section of an orbiter to
certify the propulsion system for the very first Space Shuttle launch.”
Today, the center remains NASA’s proving ground for all Space Shuttle Main
Engines and plays an integral role in testing component and propulsion
for the future. The 520-second test on April 21 will be a flight
test for the Pratt & Whitney high-pressure fuel turbo pump.
