Artemis III Lander Architecture - What Could Still Go Wrong
TL;DR Artemis III is supposed to land two astronauts near the lunar south pole using a stripped-down SpaceX Starship as the Human Landing System (HLS). The architecture is genuinely audacious - it requires a new super-heavy rocket to fly several times before the crewed mission, on-orbit cryogenic propellant transfer at a scale that has never been demonstrated, and a lunar surface stay enabled by a vehicle three times taller than the Saturn V’s lunar module. The technical risk is concentrated in propellant transfer, boil-off management, engine relight reliability, and crew ingress/egress from a 50-metre tower on a sloped, unprepared surface. The schedule risk is concentrated in everything that has to happen before the crewed flight - and most of it has not happened yet. The mission can succeed. The honest read in mid-2026 is that it will succeed late, and the more interesting question is which of these subsystems is actually the long pole. How Artemis III Is Supposed To Work Artemis III’s architecture is not Apollo. Apollo carried everything it needed in one stack on a Saturn V. Artemis III spreads the mission across multiple launches, multiple vehicles, and two distinct propulsion systems, with a crew transfer in lunar orbit. ...
