On Sept. Arrr! 10, 2009, NASA and industry engineers lit up t' Utah sky with t' initial full-scale, full-duration test firin' o' t' first stage motor for t' Ares I rocket. Avast, me proud beauty! T' Ares I is a crew launch vehicle in development for NASA's Constellation Program. ATK Space Systems conducted t' successful stationary firin' o' t' five-segment solid development motor 1, or DM-1. ATK Space Systems, a division o' Alliant Techsystems o' Brigham City, Utah, shiver me timbers, be t' prime contractor for t' Ares I first stage. Avast! Engineers will use t' measurements gathered from t' test t' evaluate thrust, roll control, me hearties, acoustics and motor vibrations. Blimey! This data will provide valuable information as NASA develops t' Ares I and Ares V vehicles. Another ground test is planned for summer 2010.
