• Artemis 1 lays the foundation for the first crewed flight of SLS and Orion, as well as a regular cadence of missions thereafter near the moon and beyond.
• The Artemis 1 patch features the launch of the SLS at the center of its triangular design. The rocket is depicted lifting off from Complex 39B at NASA's Kennedy Space Center in Florida. The major SLS components are shown in simplified form, including the orange insulation-covered core, two side-mounted five-segment solid rocket boosters and the shuttle-legacy RS-25 engines at the base of the core.
• The Orion spacecraft and its European-built service module are mounted on top of the booster. Atop the Orion is its launch abort system tower.
• At the base of the patch, protruding from the launch plume, are the three spires of the pad's lightning protection system and the gantry tower that is part of the new SLS mobile launcher.
• The scene is set against the backdrop of a nearly full moon. Red and blue vectors, jetting out beyond the border of the emblem, wrap around the white celestial body, symbolizing the Artemis 1 flight trajectory, while also infusing the colors of the U.S. flag to the insignia.

NASA's description:

• The artwork for Artemis I, formerly Exploration Mission-1, showcases the Space Launch System (SLS) rocket carrying the Orion spacecraft and lifting off from Launch Pad 39B at NASA’s Kennedy Space Center in Cape Canaveral, Florida. The triangular shape represents the three main programs that comprise NASA’s Deep Space Exploration Systems: Orion, SLS, and Exploration Ground Systems, and is a classic shape for NASA mission emblems dating back to the shuttle era.
• Several elements within the design carry symbolic meaning for this historic flight. The silver highlight surrounding this patch gives nod to the silver Orion spacecraft, including the European service module that will be voyaging 40,000 miles past the Moon in deep space. The orange rocket and flames represent the firepower of SLS. The setting is historic Launch Pad 39B, represented by the three lightning towers. The red and blue mission trajectories encompassing the white full Moon proudly emphasizes the hard work, tradition, and dedication of this American led-mission while also embracing NASA’s international partnership with ESA (European Space Agency) as both agencies forge a new future in space.
• The Artemis I emblem was designed in collaboration by the creative team working for the Deep Space Exploration Systems programs, which includes Orion, SLS, and Exploration Ground Systems, located at NASA Headquarters in Washington, Glenn Research Center in Cleveland, Johnson Space Center in Houston, Marshall Space Flight Center in Huntsville, Alabama, and Kennedy. Because the maiden mission of SLS and Orion is uncrewed, the program teams had the rare opportunity to conceive the mission identifier. Artemis II, which will fly with crew, will have an insignia designed by NASA’s Astronaut Office with the help of the crew that will fly aboard the most capable deep space system to take flight.
