#CountdownToMars

Meet some of the humans behind the Mars 2020 mission, headquartered at the Jet Propulsion Laboratory in Southern California. They're working to build, fly and use the Perseverance rover to search for signs of ancient life on the Red Planet, and are taking time out the day before launch to answer your questions.

Featuring:
Jessica Clark, Mars 2020 fault protection engineer, JPL
Christina Hernandez, PIXL instrument engineer, JPL
Joby Razzell Hollis, astrobiologist working with the SHERLOC instrument, JPL
