Video: The launch of Orion

In a major shift, NASA is considering using two commercial launchers to send an unpiloted Orion crew capsule and its European-built service module on a test flight around the moon next year, maintaining the lunar test flight’s schedule despite fresh delays in the development of the multibillion-dollar Space Launch System that jeopardize the heavy-lifter’s 2020 inaugural flight, the agency’s administrator said in a congressional hearing Wednesday.

A three-minute test flight Tuesday morning over Cape Canaveral will help ensure NASA’s Orion crew capsule — the vehicle being built to carry astronauts back to the moon — can safely escape from a catastrophic failure on launch.

Despite protests from Texas lawmakers, NASA’s Marshall Space Flight Center in Huntsville, Ala., will manage the agency’s plans to build a lunar landing system that will carry the next man and the first woman to the surface of the moon in 2024, agency Administrator Jim Bridenstine announced Friday.
