Phase 1 calls for a minimum crew of two, a Mun flyby or orbital insertion, safe return, onboard crew control, and abort coverage through atmospheric flight. NASA expects both major contractors to fly before a winner is declared.
KOEING's R-SLS2 now carries two flawless missions and a Mach 3+ reentry validation into planning rooms. KerbalX still must resolve crew control questions for operations beyond LKO — the same questions that have shadowed its flashiest architectures.
Phase 2 remains locked: first crewed Mun landing, surface EVA and science, abort required. The Herald will publish contractor filings as they clear public release.
