Four astronauts successfully returned home to earth in a SpaceX crew Dragon spacecraft. The crew successfully landed on the International Space Station early Thursday morning. After splashing down under parachutes, the crew dove through earth’s atmosphere before splashing down underneath parachutes.

The astronauts, part of a mission called crew-3, launched to space in the same crew dragon back in November. Tom Marshburn, Raja chari, and Kayla Barron were on board the crew dragon.

Russia destroyed one of its own satellites with a missile shortly after they arrived at the ISS. The crew-3 astronauts and Russian cosmonauts had to shelter inside their spacecraft in case the resulting debris damaged the space station the crew was able to return to a normal work schedule.

Many questioned the stability of the ISS partnership between NASA and Russia’s state space Corporation, Roscosmos. The crew-3 astronauts continued their work as planned along with their Russian colleagues. Nasa administrator Bill Nelson assured Congress on May 3rd that it was business as usual on board the ISS.

Crew-3 was SpaceX’s third mission to the ISS for NASA as well as the company’s eighth time launching astronauts to space. Spacex holds a contract with NASA to periodically send astronauts to and from the International Space Station.
