Nasa's first step in their plan to send humans back to the surface of the Moon is fast approaching. The programme, called Artemis, is costing tens of billions of dollars and will begin with Artemis I, scheduled to launch on 29 August. The uncrewed mission will send the Orion spacecraft to orbit the Moon. Subsequent missions in the coming years aim to return humans to the Moon’s surface for the first time in over 50 years and will include a woman and a person of colour. Nasa sees a return to the Moon as a way to prepare for a mission to Mars. But what exactly are they hoping to learn and what difference will any of it make to all of us back here on Earth?
