NASA Administrator Jim Bridenstine told a Senate hearing today that his agency is looking into an option to double up commercial launch vehicles in order to keep a crucial test mission for its Orion spaceship and European-built service module on schedule for mid-2020.
The shift would take NASA’s own heavy-lift Space Launch System rocket, or SLS, out of the rotation for the uncrewed test flight around the moon, known as Exploration Mission 1 or EM-1.
