Two astronauts who lived on the NASA space station for nine whole months are finally back home! They traveled back to Earth in a spaceship called a Dragon built by SpaceX. They were part of Mission Crew-9. This mission was a big deal because it showed that the Dragon was reliable for long trips. It also showed us how the astronauts' bodies adapted to space. Their mission was packed with important research. They studied how planets grow in space, made new materials, and even looked at how the Earth's atmosphere is changing. They are now being asked by scientists to share their experience and data.
