NASA astronaut Jeff Williams has broken the record for the longest time in space by an American.
Williams safely touched back down to Earth yesterday with two Russian cosmonauts Alexey Ovchinin and Oleg Skripochka, after living on board the International Space Station.
Jeff has spent a total of 534 days in space. He now holds the American record for the most time living in space.
However, Jeff still has a long way to go to beat the world record holder Gennady Padalka.
The Russian cosmonaut has spent a whopping 879 days in space, that’s nearly two and a half years!
