A SpaceX Dragon capsule has arrived at the International Space Station, just over 24 hours after it was launched from Florida on board a SpaceX Falcon 9 rocket.

The capsule is carrying four new crew members who will oversee the arrival of two new rocketships during their stint.

The new U.S.-Russian crew will replace a crew from the U.S., Denmark, Japan and Russia.

Boeing’s long-delayed Starliner capsule with test pilots and a new private mini shuttle with cargo are due to arrive during the new crew’s six-month stay.
