NASA Astronaut Tracy Dyson points to the Expedition 71 patch on her flight suit on Wednesday, March 5, 2025. Dyson and her fellow Expedition 71 crewmates Matthew Dominick, Michael Barratt, and Jeanette Epps answered questions from students at Elsie Whitlow Stokes Community Freedom Public Charter School in Washington.<\/p>\n
While aboard the International Space Station, Dyson conducted\u00a0dozens of scientific and technology activities\u00a0to benefit future exploration in space and life back on Earth. She\u00a0remotely controlled a robot\u00a0on Earth\u2019s surface from a computer aboard the station and evaluated orbit-to-ground operations. She operated a 3D bioprinter to\u00a0print cardiac tissue samples, which could advance technology for creating replacement organs and tissues for transplants on Earth. Dyson also participated in the\u00a0crystallization of model proteins\u00a0to evaluate the performance of hardware that could be used for pharmaceutical production and ran a program that uses\u00a0student-designed software\u00a0to control the station\u2019s free-flying robots, inspiring the next generation of innovators.<\/p>\n
