Spanning 184 days in space, Dyson’s third spaceflight covered 2,944 orbits of the Earth and a 78-million-mile journey as an Expedition 70/71 flight engineer. Dyson also conducted one spacewalk of 31 minutes, bringing her career total to 23 hours, 20 minutes on four spacewalks. Dyson returned to Earth on Sept. 23, as planned, along with her crewmates, Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub.

Dyson launched on March 23 and arrived at the station March 25 alongside Roscosmos cosmonaut Oleg Novitskiy and spaceflight participant Marina Vasilevskaya of Belarus. Novitskiy and Vasilevskaya were aboard the station for 12 days before returning home with NASA astronaut Loral O’Hara on April 6.

While aboard the orbiting lab, Dyson conducted dozens of scientific and technology activities to benefit future exploration in space and life back on Earth. She remotely controlled a robot on Earth’s surface from a computer aboard the station and evaluated orbit-to-ground operations. She operated a 3D bioprinter to print cardiac tissue samples, which could advance technology for creating replacement organs and tissues for transplants on Earth.

Dyson also participated in the crystallization of model proteins to evaluate the performance of hardware that could be used for pharmaceutical production and ran a program that uses student-designed software to control the station’s free-flying robots, inspiring the next generation of innovators.
