Die Besatzung der Artemis II hat sich offiziell in Quarantäne begeben.

PGo has very little to do with the crew and very much to do with the big orange rocket. It’s not any closer until that thing is fueled and checked out.

It definitely feels like a go now that the crew is in quarantine, but we’re probably at a 95% rather than a 100% guarantee just yet. Even this close to April 1st, there are still variables like Florida’s unpredictable weather, final technical checkouts at the pad, or even minor sensor readings that can trigger a scrub. It’s the most exciting milestone so far, but in spaceflight, nothing is official until the countdown hits zero and those engines actually light up!
