NASA’s Artemis II mission, which will send humans around the moon for the first time in over five decades, could launch as early as March. This is part of a larger campaign to establish a long-term presence on the moon and eventually prepare for human space flight to Mars.

Meanwhile, China also has a goal of landing humans on the moon by 2030, setting up a kind of modern space race. One reason for the rush: It's like a game of finders keepers, said Saadia Pekkanen, a professor focused on space law and policy at the University of Washington.
