Perseverance Mars Rover Marble Countdown

A jar with an Earth sticker and one marble inside and a jar with a Mars sticker full of marbles are seen on a conference room table of the Mission Support Area (MSA)on Wednesday, Feb. 17, 2021, at NASA's Jet Propulsion Laboratory in Pasadena, California. The Perseverance Mars rover team has been moving one marble a day since launch from jar to jar. The Perseverance Mars rover is due to land 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.
