Mae Jemison: Physician, Engineer and Trailblazing NASA Astronaut

Early life and education

Jemison grew up with a strong interest in science and technology. She attended Stanford University, where she studied chemical engineering and graduated with a bachelor’s degree; she later earned a medical degree from Cornell University. After medical school she served as a Peace Corps medical officer in West Africa, practicing clinical medicine and public health before returning to the United States to continue her work and training as a medical professional.

NASA career and spaceflight

Selected by NASA in the late 1980s, Jemison became part of a diverse astronaut corps and trained for spaceflight as an astronaut. In September 1992 she flew aboard the Space Shuttle Endeavour as a mission specialist; that flight made her the first African‑American woman in space. During the mission she conducted scientific experiments, participated in crew activities, and helped demonstrate the value of interdisciplinary expertise in space research.

Later career and public work

After leaving NASA, Jemison pursued projects that combine science, technology and education. She founded organizations and companies focused on applying technology to everyday problems and on improving science education for young people. She has also spoken widely about the importance of diversity in science and encouraged broader public engagement with research and innovation. Jemison made appearances in popular culture, including a guest role on Star Trek: The Next Generation, reflecting her interest in science, imagination and outreach.
