Christina Hernández is a Mexican-American systems engineer at NASA.^[1] She was involved in STEM programs, which led her to a career in NASA where she has worked on the Mars Perseverance Rover, along with being a micrometeoroid and orbital debris specialist at the Jet Propulsion Laboratory. Her contribution to aerospace involved adding safety within spacecraft.^[2] Also as an advocate for Latinas in STEM, Hernandez was a recipient of the Hispanic Heritage Foundation awards in 2021.^[3]

Hernández's cultural identity is Mexican-American.^[1] Her birthday is on March 10. She grew up in Los Angeles, California.^[2] She continues to reside in California.^[4] Hernández was always interested in anything space-related and even did her own research about space from a young age.^[1] Her interest on the subject of aerospace was first introduced when she was at a local library looking at information on the planet Saturn.^[2]

Hernández told We Are Mitú how she suffered from imposter syndrome when she worked with NASA.^[1] Hernández advocates for Latinas in STEM.^[1]

Hernández was enrolled at a magnet high school in Carson, California called California Academy of Mathematics and Science, which has a STEM program that she participated in.^[2] She joined the robotics team in high school.^[2] She also participated in an aerospace and defense technology-based internship where she learned to ask for help.^[2] Hernández received her master's degree in aerospace engineering at California Polytechnic State University.^[1]

Hernández is a Systems Engineer for NASA in their Jet Propulsion Laboratory in Pasadena, California.^[4] When first starting out with NASA, she was part of their Natural Space Environments group. Hernández worked as a micrometeoroid and orbital debris specialist.^[4] Hernández also worked with STABLE which is the Subarcsecond Telescope and BaLloon Experiment as a mission assurance manager.^[4] She then joined the Mars team after her work with STABLE, working on the Mars Perseverance Rover's payload development and delivery team.^[4] She is on the team of system engineers developing and testing the newest rover for their Mars exploration.^[5] Hernández has also worked on three of the seven science instruments, which are MEDA (weather station), RIMFAX (radar), and PIXL (spectrometer), where she was able to get them through different phases of development and testing.^[4]

Additionally, Hernandez wrote an article for the New York Times where she reflects on a series, called Turning Points.^[6] In her reflection, she shared her intel on how a scientific gadget that was named Perseverance landed on Mars on February 18, 2021.^[6]

Hernández's work as a micrometeoroid and orbital debris specialist ensured the safety of spacecraft in relation to orbital debris and other obstacles, such as radiation, through many analyses and assessments.^[4] During Hernánandez's time with STABLE, she completed a project called Comet Sliding Spring which led Mars Reconnaissance Orbiter, Odyssey, and MAVEN safely in the comet event.^[4] This led Hernánandez to work with the Mars team for their mission.^[5] Hernández's contribution consisted of ensuring that instruments used by NASA were being built safely and tested them to see if they performed properly when taken out on Mars.^[5]
