SpaceX sends four astronauts to the ISS

Four astronauts are on their way to the International Space Station after launching from Florida aboard a SpaceX rocket.

The Crew-13 mission includes two Americans, a Canadian astronaut and Russian cosmonaut.

The Space-X Falcon 9 rocket carrying the Dragon capsule lifted off successfully despite concerns about bad weather.

The crew will spend about six months in orbit, carrying out research into human health and performance in space.
