Deputy project manager Katie Stack Morgan gives remarks during a NASA Perseverance rover initial surface checkout briefing, Friday Feb. 19, 2021, at NASA's Jet Propulsion Laboratory in Pasadena, California. The Perseverance Mars rover landed on Mars Thursday, Feb. 18, 2021. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.
