Dragon Crew-4 astronauts 'excited' to return to Earth

STORY: "Our families make such big sacrifices for us to be able to come up here and do this amazing thing to benefit humanity, but getting back and seeing them, getting those first hugs when we get back is really going to be awesome," said Hines during a news conference from space broadcasted by NASA.

"We've had an extraordinary experience under Oleg and Samantha's leadership, we've done a lot of science, take in some amazing views, but now we are excited to get home to our families," Lindgren added.

The pair, along with NASA astronaut Jessica Watkins and European Space Agency astronaut Samantha Cristoforetti, will return to Earth aboard SpaceX Dragon Capsule after spending almost six months in the ISS.
