There’s something powerful about representation—seeing someone who looks like you achieving great things. It’s a reminder that big dreams are possible, that barriers can be broken, and that brilliance exists in every community. The voices and stories of marginalized people deserve to be heard—not just because of their struggles, but because of their extraordinary achievements. For little girls and boys (and adults too), seeing trailblazers who share their background or experiences can be life-changing.


Celebrating Dr. Mae Jemison – The First Black Woman in Space

This month, as we celebrate Black History Month, honor the outstanding achievements of Black individuals, and recognize their impact on history, it is only fitting to highlight a trailblazing woman who redefined what’s possible—Dr. Mae Jemison, the first Black woman to travel to space. Her groundbreaking journey in science, medicine, and space exploration is an inspiring testament to perseverance, innovation, and the power of believing in oneself.


Dr. Mae Jemison is a true pioneer who proved that the sky is not the limit—it’s just the beginning.

Early Life and Education

Born on October 17, 1956, in Decatur, Alabama, Dr. Mae Jemison moved with her family to Chicago at the age of three. Her parents, Charlie and Dorothy Jemison, nurtured her passion for science and space from a young age. They often took her to Chicago’s Museum of Science and Industry and the Field Museum of Natural History, fostering her early interest in the sciences.


Dr. Jemison was fascinated by space travel and was a voracious reader, consuming stories about space. She was particularly inspired by the television show Star Trek and African-American actress Nichelle Nichols' portrayal of Lieutenant Uhura, which further stoked her interest in space.


“Sometimes people want to limit you because of their own imaginations.” – Dr. Mae Jemison

Despite facing challenges, including teachers who questioned her ambitions to become a scientist, Jemison remained determined. She graduated from Morgan Park High School in 1973 and entered Stanford University at just 16, earning a Bachelor of Science in Chemical Engineering and a Bachelor of Arts in African and African-American Studies in 1977. She then pursued a medical degree at Cornell University, graduating in 1981.


While at Cornell, Dr. Jemison’s commitment to international medicine and humanitarian work deepened. She traveled to Thailand, providing medical care to Cambodian refugees in camps, gaining firsthand experience in global health challenges. In 1979, she furthered her international exposure by studying in Kenya, broadening her understanding of healthcare in diverse settings. These experiences reinforced her dedication to serving underserved communities.


Medical Career and the Peace Corps

After earning her Doctorate in Medicine in 1981, Dr. Jemison completed an internship at the Los Angeles County Medical Center and worked as a general practitioner in Los Angeles. However, her ambitions extended far beyond traditional medical practice. She had a deep interest in global health and humanitarian work, which led her to volunteer in refugee camps in Thailand during her medical training.


Her passion for international medicine took her to West Africa, where she served as a Peace Corps Medical Officer from 1983 to 1985. In this role, she was responsible for overseeing the healthcare of Peace Corps volunteers in Sierra Leone and Liberia, managing public health projects, providing medical care, and working on medical research initiatives.


During her tenure, she developed vaccination programs, improved water sanitation, and implemented preventative health measures to combat diseases such as hepatitis, schistosomiasis, and malaria. She also played a crucial role in training local medical staff, ensuring that sustainable healthcare practices could continue after her departure.


These formative years helped lay the foundation for her multifaceted career—one that would later bridge medicine, space exploration, and technology-driven humanitarian work.


Journey to NASA and Historic Spaceflight

In 1987, Dr. Jemison was selected by NASA as an astronaut candidate, standing out among approximately 2,000 applicants competing for just 15 positions. Her selection was groundbreaking, making her the first Black woman ever admitted into NASA’s astronaut training program.


She completed her training as a Mission Specialist in 1988, mastering critical skills such as microgravity operations, robotics, and scientific research in space.


On September 12, 1992, Dr. Mae Jemison made history as the first Black woman to travel to space, launching aboard the Space Shuttle Endeavour on mission STS-47, a joint venture between the United States and Japan.


During the eight-day mission, she conducted life and material sciences experiments, focusing on bone cell research, motion sickness in space, and the effects of weightlessness on the human body—pioneering research still relevant for long-duration space travel today.


Beyond her scientific contributions, Dr. Jemison honored those who paved the way before her by bringing personal mementos into space, including a poster from the Alvin Ailey American Dance Theater—symbolizing the power of artistic expression and movement, a West African statuette—honoring her cultural roots, and a photo of Bessie Coleman—the first African American woman to hold a pilot’s license, paying tribute to a fellow trailblazer in aviation.


Her presence aboard Endeavour shattered barriers and expanded the possibilities for future generations of Black women and underrepresented groups in STEM.
