Expedition 43 began in March 2015, with the departure of Soyuz 40 and the change of command leaving Terry Virts (NASA) as the commander. The other two crew on board are Samantha Cristoforetti (ASI-ESA), and Anton Shkaplerov (RSA). Three additional crewmembers, Scott Kelly (NASA), Mikhail Kornienko (RSA), Gennady Padalka (RSA), arrived to the International Space Station in late March bringing the crew size to six. Padalka will return to Earth in October 2015, and Kelly and Kornienko will remain onboard ISS for a full year, and return to Earth in March 2016.

Expedition 43 on-board the ISS officially ended on June 10, 2015 with a Change of Command ceremony. NASA astronaut Terry Virts, the Expedition 43 commander, handed the station over to Russian cosmonaut Gennady Padalka. Virts and the other two Expedition 43 crew members, Shkaplerov and Cristoforetti returned to Earth on June 11, 2015. These three crewmembers were on board ISS for a 199-day mission that included several spacewalks, technology demonstrations, and hundreds of scientific experiments spanning multiple disciplines, including human and plant biology. The returning crewmembers will celebrate individual milestones in their space exploration careers. With the completion of his second mission, Virts now has spent 212 days in space. Shkaplerov, having completed his second long-duration mission on the station, has spent 364 days in space. Cristoforetti set a new record for single mission duration by a female astronaut, with 199 days in space on her first flight, surpassing NASA astronaut Suni Williams' previous record of 195 days as a flight engineer on Expeditions 14 and 15 from December 2006 to June 2007.
