A-1 to Constellation

The A-1 Test Stand at NASA Stennis Space Center near Bay St. Louis, Miss., was the focus of a ceremony held Thursday to transition the storied facility to a new program of work: testing the J-2X engines that will power the agency's next generation spacecraft, Ares I & V. Standing before the historic structure, with a plaque commemorating the change, are (from left) SSC Center Director Richard Gilbrech; NASA Associate Administrator for Exploration Systems Scott Horowitz; and NASA Space Operations Deputy Associate Administrator for Program Integration Michael Hawes. Ares vehicles are the crew and cargo launch vehicles being developed under NASA's Constellation Program.
