The international crew of astronauts and a cosmonaut that will launch to the International Space Station includes: NASA astronaut Jasmin Moghbeli, European astronaut Andreas Mogensen, Japanese astronaut Satoshi Furukawa and Russian cosmonaut Konstantin Borisov.

Crew-7 represents the seventh crew rotation mission with SpaceX to the ISS. It’s also the third crewed launch of the year from Florida’s Space Coast.

Wakata has flown on multiple missions to the ISS, most recently as a mission specialist for Crew-5.

“By doing this in an international manner, we create international partnerships that will take us beyond the low earth orbit to the moon,” Wakata said.
