Tracy Dyson, a former postdoctoral scholar in chemistry at UC Irvine, has completed three voyages in space — in 2007 aboard the space shuttle Endeavour, six months in 2010 serving on the International Space Station, and six months on the ISS in 2024. She will recount those experiences in a lecture at the Beckman Center on Jan. 15. The free lecture, which is open to the public, will provide an exceptional opportunity for the Orange County community, including school children age 10 and older, to see an astronaut in person (along with other distinguished scientists from UC Irvine) and learn first-hand about science, space, and what it takes to become an astronaut. The talk will be live streamed in an overflow room to accommodate all visitors.
