NASA Moves Artemis II Earliest Launch Opportunity to Feb. 8 After Weather Delay

A weather-driven rehearsal change pushes the earliest Artemis II launch date to Feb. 8.

Overview

  • NASA rescheduled the wet dress rehearsal propellant loading to Feb. 2, with a simulated launch window opening at 9 p.m. EST after an approximately 49-hour countdown.
  • An Arctic cold snap with high winds in Florida prompted managers to adjust the timeline, eliminating Feb. 6–7 opportunities and shifting the first possible attempt to Feb. 8.
  • The four-person crew remains in health-stabilization quarantine in Houston, with travel to Kennedy Space Center to be set after teams review rehearsal results.
  • Ground teams fixed braking on the emergency egress baskets and are analyzing Orion’s potable water system after elevated total organic carbon was detected.
  • Recovery forces are running Pacific splashdown drills as pad checks, environmental protections for cold conditions, and payload stowage continue at Launch Complex 39B.
