This week, Locust Valley Intermediate School fifth graders learned about space exploration from NASA engineer and brother of science teacher Caroline McBride, Justin Cassidy. Cassidy made the trip up from Maryland’s Goddard Space Flight Center, where he helps develop tools for astronauts to use during missions, to share his expertise and inspire students with stories of his work in space flight. He answered students’ questions about astronaut training and the intricacies of space travel.
