A space shuttle-era main engine is undergoing a series of daily test firings to demonstrate its suitability for use on a reusable spaceplane under development.
The Aerojet Rocketdyne AR-22 engine is in the midst of a series of 10 100-second engine firings over the course of 10 days at NASA's Stennis Space Center in Mississippi. As of July 2, the company has completed six such tests and was on track to complete the rest on schedule.
The engine is a version of the Space Shuttle Main Engine with only minor modifications, said Jeff Haynes, AR-22 program manager at Aerojet, in a July 2 interview. "We're not designing or building any new hardware for this engine," he said. "We're taking and making use of existing hardware, most of it being flight proven."
One minor difference in the engine, he said, is using a new flight controller, or computer system, from the updated version of the RS-25 engine intended for use on NASA's Space Launch System. "The rest of it is not new technology," he said.
The purpose of the test series is to demonstrate that the engine can be used 10 times in 10 days. That is a major requirement of the Defense Advanced Research Project Agency's Experimental Spaceplane program, for which the AR-22 will power Boeing's Phantom Express vehicle.

It seems the Air Force is looking for ways to rapidly replace satellites that have been attacked.
Hmmm, the base engine is tech from 20 plus years old. I guess NASA and its contractors need more Muslim outreach. /s
In the 60s we owned property on Pearl River which we used as a summer home. It was within the buffer zone of the Stennis Center.
The government bought the property from us at a fair price then sold us the house only for $1. Wemoved the house to property which was out of the buffer zone on the coast of Mississippi.
Hopefully it's not a scary black "thingie".. d;^)
(Do I need the /s?)
The internal combustion engine was first used commercially in 1859 ... so do car makers need more muslim outreach also?
Just put a suitable pink hat on the nose and all will be well ...
