Pettit returned to Earth on April 19 (April 20, Kazakhstan time), along with Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner. Pettit celebrated his 70th birthday on April 20. He spent 220 days in space as an Expedition 71/72 flight engineer, bringing his career total to 590 days in space during four spaceflights. Pettit and his crewmates completed 3,520 orbits of Earth over the course of their 93-million-mile journey. They also saw the arrival of six visiting spacecraft and the departure of seven.

During his time on orbit, Pettit conducted hundreds of hours of scientific investigations, including research to enhance on-orbit metal 3D printing capabilities, advance water sanitization technologies, explore plant growth under varying water conditions, and investigate fire behavior in microgravity, all contributing to future space missions.

He also spent time aboard the space station sharing his photography, often posting images to his X account. He took more than 670,000 photos during his stay.
