The Crew-13 mission is the first astronaut launch from the U.S. in six months.

Four astronauts blasted off Thursday on a space station mission that will stretch until spring, among them a Canadian whose wife will give birth while he’s away.

The SpaceX Dragon spacecraft carried NASA astronauts Jessica Watkins and Luke Delaney, CSA (Canadian Space Agency) astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov.
