SpaceX successfully docked at the International Space Station on Sunday, space officials said.

Astronauts docked the SpaceX Crew Dragon capsule at the ISS after a one-day expedition to the orbiting laboratory. There, they will replace the four astronauts who have been living up there since March.

The astronauts took off from Florida and traveled 30 hours to the orbiting laboratory, NASA said in a tweet.
