The NASA Ares I-X Flight Test was a pivotal milestone in the Constellation program, aiming to develop the next generation of human spaceflight vehicles for NASA's Artemis program and beyond.
The Ares I-X was an uncrewed test flight of the Ares I rocket, which was designed to be the crew launch vehicle for the Constellation program's Orion spacecraft.
This ambitious endeavor sought to revive crewed lunar exploration and enable future missions to Mars.
