After a series of delays, Elon Musk's private company SpaceX launched four astronauts to the International Space Station on Wednesday night on the "Crew-3" mission.

The orbital outpost is currently operating with just one NASA astronaut in the US segment to welcome the incoming crew, after the astronauts of the earlier Crew-2 mission splashed down in the Gulf of Mexico on Sunday night.
