Why are NASA ​​astronauts practising moonwalk in Arizona desert?

NASA astronauts Kate Rubins and Andre Douglas are practising moonwalks in Arizona's San Francisco Volcanic Field to prepare for the Artemis III launch scheduled for 2026. The Arizona desert has been chosen due to its resemblance to lunar terrain with its volcanic features, craters and faults. The rehearsal aims to identify any challenges that may arise during the mission.
