Description
The Ares I–X vehicle consisted of a functional four-segment solid rocket booster (SRB) stage, a fifth segment mass simulator, an upper stage simulator (USS), which was similar in shape and heavier than the actual upper stage, as well as a simulated Orion crew module (CM) and launch abort system (LAS). Since the actual upper stage hardware could not be produced in time for the flight test, the upper stage mass simulator allowed the booster to fly approximately the same trajectory through the first stage of flight. The USS and the CM/LAS mass simulators launched by the Ares I-X were not recovered and fell into the Atlantic Ocean. The first stage, including the fifth segment mass simulator, was recovered to retrieve flight data recorders and reusable equipment.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“It [Egypt] has more wonders in it than any other country in the world and provides more works that defy description than any other place.”
—Herodotus (c. 484–424 B.C.)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
