Why is NASA going to the moon again?

NASA’s Artemis II mission is set to launch this week, which could bring humanity close to the moon for the first time since 1972. It’s a mission that’s over twenty years in the making – and even though it’s not the first venture out to the moon, it still involves a lot of firsts. If all goes to plan, the mission will bring the first woman, person of color and non-American close to the moon. But why are we embarking on a sequel space mission to begin with? And while they’re up in space, what could scientists learn about the possibility of life in space for those of us still on Earth?Interested in more science behind current events?
