| Summary | Boeing's NASA CCP capsule. The Crew Flight Test (May 2024) was plagued by helium leaks and RCS thruster failures, stranding NASA astronauts Butch Wilmore and Suni Williams for 8 months before SpaceX Crew Dragon rescued them. | NASA's deep-space crew capsule designed for Artemis lunar missions and beyond. Larger than Apollo, pairs with the European Service Module (ESM). Artemis 1 flew uncrewed in Nov 2022; Artemis 2 (first crewed) planned 2026. | Winged lifting-body spaceplane awarded NASA CRS-2 cargo contract. Lands on conventional runways, potentially at any airport with a ~4,500 m runway. First flights will be uncrewed cargo missions. Landing gear test failure in 2023 caused further delays. |
