Four diaper-wearing astronauts undocked from the International Space Station on Monday and have embarked on their journey home following a 200-day stay in space.

NASA’s Shane Kimbrough and Megan McArthur, along with the European Space Agency’s Thomas Pesquet and Japan Aerospace Exploration Agency’s astronaut Akihiko Hoshide separated from the ISS at 2:05pm ET, as scheduled, and are now on track for at 10:33pm ET splashdown off the Florida coast.

Their return was initially set for Sunday afternoon, but high winds pushed the return for the Crew-2 team back one day.
