America is eagerly awaiting the return of two astronauts who have been stuck on the ISS since last June. Here's who they are.

Four astronauts boarded SpaceX’s Falcon 9 rocket to replace Williams and Wilmore at the ISS.. These four astronauts are - NASA astronauts Anne McClain and Nichole Ayers, Japan Aerospace Exploration Agency (JAXA ) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov.

Sunita Williams and Butch Wilmore should have been back to earth nine months ago. However, they have been orbiting the planet aboard the International Space Station (ISS).
