The first humans to travel around the moon in more than 50 years experience hours of scientific wonder — and moments of deep emotion.

NASA’s four Artemis astronauts swung behind the moon and are headed home, in a journey that shattered space travel distance records and brought people the closest they’ve been to the lunar surface in more than 50 years.

The world has tracked the journey of NASA’s Artemis II mission for five days. The four astronauts have launched into space, tested life support and other important systems of their Orion spacecraft, tangled with the vehicle’s toilet,
