This week in 2012, engineers tested the power pack assembly of the Pratt & Whitney Rocketdyne-built J-2X engine at NASA’s Stennis Space Center. The test ran for 278 seconds and verified the newly installed strain gauges designed to measure the turbine structural strain when the turbopump is spinning at high speeds. Today, NASA’s Marshall Space Flight Center is playing a vital role in the Artemis program by developing the Space Launch System, the backbone of NASA’s exploration plans and the only rocket capable of sending humans to the Moon and Mars. The NASA History Program is responsible for generating, disseminating, and preserving NASA’s remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological, and scientific aspects of NASA’s activities in aeronautics and space.
