SpaceX Crew-4 mission patch
Hines, Cristoforetti, Watkins, and Lindgren (L-R)
SpaceX Crew-4 is the Crew Dragon's fourth NASA Commercial Crew operational flight, and its seventh overall crewed orbital flight. The mission launched on 27 April 2022 at 07:52 UTC before docking with the International Space Station (ISS) at 23:37 UTC. It follows shortly after the private Axiom 1 mission to the ISS earlier in the month utilizing SpaceX hardware. Three American (NASA) astronauts and one European (ESA) astronaut are onboard the mission. 
Crew-4 is the maiden flight of the Crew Dragon spacecraft named Freedom, named such by the crew because it "celebrates a fundamental human right, and the industry and innovation that emanate from the unencumbered human spirit". The booster used on this mission was the B1067, which makes it the first Commercial Crew mission to use a booster on its fourth flight (it previously was used to launch SpaceX Crew-3 in 2021).
NASA astronauts Kjell Lindgren and Robert Hines were announced on 12 February 2021 to the crew. Samantha Cristoforetti was named the commander of Expedition 68 on 28 May 2021. Jessica Watkins was named Mission specialist on 16 November 2021. Cristoforetti was later removed as commander of Expedition 68 due to the shortening of the Crew-4 mission.

The planned mission duration is around six months. The European part of the mission is called Minerva, named after the Roman goddess of wisdom, and it is European astronaut Cristoforetti's second mission to the ISS.
Crew-4 is scheduled for a long duration stay of up to six months aboard station conducting science and maintenance before returning to Earth in the fall of 2022.
Inspired by the Roman goddess of wisdom, the handicrafts and the arts, the name Minerva is a homage to the competence and sophisticated craftmanship of the men and women all over the world who make human spaceflight possible.
