Valerino was born to a Mississippi Choctaw mother and African-American father. She grew up on the Mississippi Choctaw reservation and is an enrolled member of the tribe.[1] When she was ten, she moved with her family to New Orleans. A few years later she saw the Space Shuttle Challenger explosion on television and became interested in science.[2] Valerino learned cello at age twelve, and still plays in the Pasadena Community Orchestra.[1][3] During high school, Valerino interned as a mechanical engineer as part of NASA's Summer High School Apprenticeship Research Program, where highly achieving students shadow NASA professionals.[4]
She obtained a bachelor's degree in mechanical engineering from Stanford University, and received her master's degree and doctoral degrees in Mechanical Engineering with a specialty in Aero-Astronautics from Rice University.[5][6] During summers at graduate school, Valerino interned at Johnson Space Center in Houston and Stennis Space Center in Hancock County, Mississippi, where she worked on the X-38 vehicle (International Space Station lifeboat) team.[7] Her dissertation, Optimizing Interplanetary Trajectories to Mars via Electrical Propulsion, was submitted to Rice in 2005.[8] She was the first Native American to earn a PhD in engineering at Rice University.[7]
Research and career
Cassini-Huygens lifted off with a Titan 4(01)B from Launch Complex 40.
Valerino joined the Jet Propulsion Laboratory's Mission Design and Navigation Section in 2005.[6] She first worked on the proposed Jupiter Icy Moon Orbiter mission, then transferred to the Cassini mission, where she was a navigator with the maneuver and trajectory team.[9][10] The Cassini mission far outlived the predicted four-year lifetime, with engineers like Valerino pushing it to thirteen years.[11] Throughout the Cassini mission, Valerino shared the spacecraft status and findings with the public.[12]
Her most recent project was the Parker Solar Probe spacecraft,[13] which launched on August 12, 2018.[14] It became the first satellite to fly as close to the sun as Helios 2 did in 1976.[15][16]
Valerino has worked to recruit and encourage the participation of under-represented groups in science.[17] This has included working with Soledad O'Brien to encourage black and Latina young women to pursue careers in STEM at the PowHERful Summit.[18] In 2016 she received the National Association for the Advancement of Colored People Education Awardfor her outreach activities.[19] In 2017, Valerino joined 21st Century Fox in their promotion of the film Hidden Figures, which tells of the role of outstanding African-American mathematicians and scientists in the Apollo program.[20][21][22][23]
Valerino is a fan of comic books. She has also discussed strong women in graphic novels on podcasts.[24]
