NASA's SpaceX Crew-3: A mission with a scientific purpose

The astronauts of NASA's SpaceX Crew-3 mission are returning to Earth after spending more than six months in space. The four crew members -- ESA astronaut Matthias Maurer, NASA astronauts Kayla Barron, Raja Chari, and Tom Marshburn, and NASA astronaut Kayla Barron -- will return to Earth on a SpaceX Crew Dragon spacecraft. While on board the orbiting laboratory, these crew members participated in hundreds of scientific experiments and technological demonstrations. This important research produces many improvements and advantages for people on Earth while assisting in preparing humans for upcoming space exploration missions.
