Diana Trujillo is a Colombian aerospace engineer at the NASA Jet Propulsion Laboratory. She currently leads the engineering team at JPL responsible for the robotic arm of the Perseverance rover.
Trujillo joined NASA in 2007, working at Goddard Space Flight Center on the Constellation program and the Jet Propulsion Laboratory on human and robotic space missions. She has served many roles, including Surface Sampling System Activity Lead and Dust Removal Tool Lead Systems Engineer. She was responsible for ensuring Curiosity’s sampling fulfilled its science objectives dust-free while maintaining operational safety. The Dust Removal Tool took her six months to develop, and brushes the dust of the surface of Mars to allow scientists to investigate the surface below. It was used on Curiosity’s 151st day on Mars. In 2009 she was appointed telecom systems engineer for the Curiosity Rover. Trujillo was responsible for the communications between the spacecraft and scientists on Earth. She has also been Flight Ground Systems Engineer and Vehicle System Testbed Mars Surface Lead. She was at the Jet Propulsion Laboratory when the rover landed on Mars. In 2014, Trujillo was promoted to Mission Lead. That year, she was listed as the 20 most influential Latinos in the Technology Industry.
