Dr. Ronald McNair was an accomplished physicist, engineer, and NASA astronaut. He earned a Ph.D. in physics and conducted research in laser technology and molecular spectroscopy. McNair flew on the Space Shuttle Challenger mission in 1984, where he became one of the first African American astronauts. Tragically, he lost his life in the Challenger disaster in 1986, but he remains a symbol of inspiration and achievement in science and space exploration.
