The Ares I-X was an uncrewed test flight of the Ares I rocket, part of NASA's Constellation program.
It took place on October 28, 2009.
The rocket consisted of a modified Space Shuttle Solid Rocket Booster as its first stage and a simulated upper stage.
The flight tested the rocket's aerodynamics, control systems, and separation events, providing valuable data for the development of future crewed launches.
