Eighteen astronauts have been selected — nine men and nine women — to begin training for upcoming Artemis missions to the moon, NASA announced Wednesday. The list includes the as-yet-unnamed next man and first woman who will set foot on the lunar surface later this decade.

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.
