A new front door has been installed on the International Space Station.
The two Americans, Jeffrey Williams and Kate Rubins, hooked up a new docking port in just a few hours. The docking port is the part where new space craft arrive. So it is similar to a front door.
The station’s new door arrived last month, packed in the trunk of a space cargo capsule.
The new door means that future spaceships will be able to dock with the space station easier.
The space station is currently home to two Americans, one Japanese and three Russians. Up there for five months, Williams and two of the Russians will return to Earth in a couple weeks. Williams will conduct one more spacewalk with Rubins on Sept. 1 to retract a radiator.
A newcomer to spacewalking, Rubins is only the 11th American woman to conduct a spacewalk and the 12th in the world.
