Stennis test stand construction progressing

HANCOCK COUNTY — Construction of the A-3 Test Stand at NASA’s John C. Stennis Space Center is approaching another milestone with delivery and installation of 14 water, isopropyl alcohol (IPA) and liquid oxygen (LOX) tanks.

Nine of the tanks already have been delivered and installed, with the remaining five to arrive on-site in upcoming weeks. The focus then will turn to delivery and installation of the test cell diffuser. That work is expected to begin later this year and be completed by spring 2011. General construction work on the test stand also continues.

“Installation of the tanks moves us to the next step in construction,” A-3 project manager Lonnie Dutreix said. “This is a major project for Stennis and for NASA, and it remains fully on schedule for completion and activation in 2011.”

NASA authorized construction of the A-3 stand to provide high-altitude testing on the J-2X engine in development. The engine is a centerpiece of the agency’s plan to go beyond low-Earth orbit, back to the moon and possibly beyond.
