Following the Artemis I pre-launch briefing, meteorologists with the U.S. Space Force Space Launch Delta 45 predict a 60% chance of favorable weather conditions at the beginning of the two-hour launch window that opens at 2:17 p.m. EDT Sept 3, increasing to an 80% chance of favorable weather conditions toward the later part of the window. The primary weather concern for the two-hour launch window remains scattered rain showers. The weather guidelines for NASA’s Artemis I flight test identify conditions to launch the agency’s Space Launch System (SLS) and Orion spacecraft. Teams will continue working their way through the countdown conducting planned health checks on SLS and Orion systems. The mission management team will meet early in the morning, Saturday, Sept. 3 and give the final determination for a “go” or “no-go” decision to begin tanking operations. The uncrewed flight test will test SLS and Orion as an integrated system, demonstrating the performance of the rocket and testing the spacecraft’s capabilities as it journeys about 40,000 miles beyond the Moon over the course of about six weeks. The first in an increasingly complex series of missions, Artemis I will pave the way for long-term lunar exploration, providing the foundation for extending human presence to the Moon and beyond.
