Huntsville's newest skyscraper..new test stands planned for Marshall Space Flight Center
NASA engineers are building on the historic foundation of rocket testing in Huntsville - literally - as they prepare for critical stress tests on the core of Space Launch System, America's next deep-space rocket.
Two large new test stands are being designed for Marshall Space Flight Center, and one of those stands will be built atop the bedrock-deep foundation of the stand Wernher von Braun used to test the massive F-1 Saturn V engines.
These new tests won't shake the ground across Huntsville as those Saturn V engine tests did, because NASA does its engine testing now in the vast open space of the Stennis Space Center in south Mississippi.
But the tests in Huntsville will be critical to the new rocket meeting its tight flight schedule, and the testing program itself is a complicated choreography. For example, giant barges will transport the rocket's core components - including a 185-foot tall liquid hydrogen tank - up Alabama's river system to Huntsville from the Michoud Assembly Facility near New Orleans where they will be made.
The liquid hydrogen tank is the reason for the big new, 215-feet-high test stand that will rise on the foundation of stand 4693 used for the Saturn V engine hot-fires. Engineers will hang the 185-foot-tall tank vertically, load it with enough liquid nitrogen to cover critical areas and apply stress. "We won't shake it," Huddleston said, "but we will bend it and twist it and compress it and pull it."
