Artemis II SLS Rolls Out to Launch Complex 39B

The Artemis II SLS/Orion stack rolled out from the Vehicle Assembly Building to Launch Complex 39B at Kennedy Space Center on January 18, 2026 — the first human-rated rocket at the pad since Space Shuttle Atlantis in 2011. A subsequent wet dress rehearsal on February 2 surfaced a liquid hydrogen leak. A helium flow issue detected February 21 forced a rollback to the VAB.

Why it matters

The rollback was a real setback but not catastrophic. NASA moved methodically, which is appropriate for the first crewed deep space flight in 54 years.
