Maintenance activities
Cristoforetti and Barron joined forces to deal with a few maintenance issues in the station’s Tranquility module. Crew-4 overlapped with Crew-3 for more than a week before the latter made its way back to Earth on May 6, wrapping up a six-month mission on the ISS. Cristoforetti is no stranger to the ISS, having already spent a total of 200 days on the space station as part of Expedition 42 and 43.
