Hydrogen Reclamation and Reutilization

John C. Stennis Space Center (SSC) provides rocket engine propulsion testing for NASA’s space programs. Since the development of the space shuttle, every Space Shuttle Main Engine (SSME) has undergone acceptance testing at SSC before going to Kennedy Space Center (KSC) for integration into the space shuttle. The SSME is a large cryogenic rocket engine that uses Liquid Hydrogen (LH2) as the fuel. As NASA moves to the new ARES V launch system, the main engines on the new vehicle, as well as the upper stage engine, are currently baselined to be cryogenic rocket engines that will also use LH2. The main rocket engines for the ARES V will be larger than the SSME, while the upper-stage engine will be approximately half that size. As a result, significant quantities of hydrogen will be required during the development, testing, and operation of these rocket engines.

Digital Video Recording and Analysis With Laser Targeting

Munitions accuracy provides an advantage in leveraging and applying force and has been sought after by political and military strategists for decades. Reflecting recent advances in technology, during Gulf Wars I and II, Americans watched video on the news of U.S. precision-guided bombs destroying tanks, flying through windows, and exacting coordinates on bridges utilizing laser-guided targeting. Yet, we forget the past challenges associated with target acquisition and destruction.
