NASA's Artemis program represents the most ambitious human spaceflight effort since Apollo, aiming not only to return astronauts to the moon but also to establish a long-term presence that will pave the way for crewed Mars exploration.
The hardware that will fly the astronauts moonward includes two 177-foot-tall (54 meters) twin boosters that are the backbone of the giant Space Launch System (SLS) rocket's launch power. Recently, the two boosters that will fly on the Artemis 2 mission had an "America 250" emblem painted on their sides, in honor of the upcoming. 250th anniversary of the signing of the Declaration of Independence.
