Orion has continued development into the present day, even though NASA’s exploration focus shifted a few times under other administrations — from a moon-to-Mars Constellation program (Bush) to a “flexible destination” somewhere in deep space (Obama) to a moon-focused Artemis program (Trump). Orion made a successful uncrewed test flight in 2014 around Earth and is expected to launch on a (much-delayed) uncrewed trip around the moon and back no earlier than 2021. This moon mission will mark the debut of NASA’s Space Launch System megarocket, which is also key to NASA’s deep-space plans.
