Artemis II mission is about to fly humans to the Moon — here’s the science they’ll do Set to lift off this week, the NASA flight will take astronauts around the Moon for the first time in more than 50 years.

Like many science journalists this week, I'll covering the #ArtemisII mission for @nature.com. Our first story is now up! We explore the science that the astronauts will do on their flight — and how this advances beyond the Apollo era. 🧪🔭
