Dyson monitors a free-flying Astrobee robotic assistant inside the International Space Station's Kibo laboratory module. The Astrobee was being tested ahead of the Astrobee-Zero Robotics competition for students on Earth to write software that controls the cube-shaped, toaster-sized device on the orbital lab.

iss071e486657 (Aug. 15, 2024) --- NASA astronaut and Expedition 71 Flight Engineer Tracy C. Dyson swaps out sample processors for the Pharmaceutical In-space Laboratory experiment that is exploring the production and manufacturing of medicines to benefit astronauts in space and humans on Earth. The processors were installed in the Advanced Space Experiment Processor, or ADSEP, that can process a variety of research samples and be delivered to the International Space Station and returned to Earth aboard the SpaceX Dragon cargo craft.

iss071e007507 (April 12, 2024) --- Expedition 70 Flight Engineer and NASA astronaut Tracy C. Dyson works inside the BioFabrication Facility using the portable glovebag aboard the International Space Station's Columbus laboratory module. She was working on the Redwire Cardiac Bioprinting Investigation that may offer the ability to print food and medicines for future space crews. Results may also enable the bioprinting of replacement organs and tissues potentially alleviating the shortage of donor organs on Earth.

iss071e040122 (April 23, 2024) --- Expedition 71 Flght Engineers Tracy C. Dyson and Matthew Dominick, both NASA astronauts, collect research samples preserved inside science freezers aboard the International Space Station. The duo then transferred the samples and packed them inside the SpaceX Dragon cargo spacecraft for return to Earth and analysis in laboratories.

iss071e178079 (June 4, 2024) --- The seven-member Expedition 71 crew poses together for a portrait aboard the International Space Station's Kibo laboratory module. In the front row (from left) are, NASA astronaut Tracy C. Dyson and Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub. The trio will return to Earth aboard the Soyuz MS-25 spacecraft in September. In the back are, Roscosmos cosmonaut Alexander Grebenkin and NASA astronauts Mike Barratt, Matthew Dominick, and Jeanette Epps. The foursome launched to Earth aboard the SpaceX Dragon Endeavour spacecraft on March 3, 2024.
