The NASA mission whose Space Launch System vehicle carried the America250 logo on its solid rocket boosters was Artemis II.
In November 2025, technicians at NASA’s Kennedy Space Center applied the semiquincentennial logo to the boosters of the Space Launch System rocket prepared for Artemis II. The mission later launched in April 2026 and sent four astronauts around the Moon.
Artemis II was significant because it was the first crewed flight beyond low Earth orbit since Apollo 17 ended in 1972. Unlike Artemis I, which was an uncrewed test flight, Artemis II carried astronauts on a lunar flyby mission.
The America250 marking linked a national anniversary with the history of U.S. space exploration and the next stage of lunar missions. It also makes this detail easy to mix up with Artemis III, which is a later mission in the Artemis sequence rather than the flight associated with the logo described here.
