 Many of the tests for vehicle development and spacesuit development take place in Black Point Lava Flow in Arizona. This desert site was most likely chosen to test the vehicles and spacesuits because

• the desert site has weather most like the Moon or Mars
• the desert has plants and animals most like the Moon or Mars
• the desert site is most like the surface of the Moon or Mars
• the desert site has a temperature most like the Moon or Mars
