NASA Astronaut Tracy C. Dyson, Crewmates Return from Space Station | Space

NASA astronaut Tracy C. Dyson completed a six-month research mission aboard the International Space Station on Monday, returning to Earth with Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub.

The trio departed the space station aboard the Soyuz MS-25 spacecraft at 4:36 a.m. EDT Monday, Sept. 23, making a safe, parachute-assisted landing at 7:59 a.m. (4:59 p.m. Kazakhstan time), southeast of the remote town of Dzhezkazgan, Kazakhstan.

While aboard the orbiting laboratory, Dyson conducted multiple scientific and technology activities including the operation of 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 used student-designed software to control the station’s free-flying robots, inspiring the next generation of innovators.

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.

Spanning 184 days in space, Dyson’s third spaceflight covered 2,944…
