Congratulations are in order. NASA astronaut Jeff Williams just broke the U.S. record for cumulative spaceflight hours, previously set by Scott Kelly.
Five hundred and twenty days is a lot of time to spend away from home, and especially when that time is spent weightless in a tiny metal capsule, orbiting miles above earth in the endless vacuum of space.
Luckily for Williams, he’s returning on September 5. Then, he’ll have logged 534 cumulative days in space.
