We’re scientists and engineers working on NASA‘s Perseverance rover and Ingenuity helicopter that just landed on Mars. Ask us anything! : IAmA

The largest, most advanced rover NASA has sent to another world landed on Mars, Thursday, Feb. 18, 2021, after a 293 million mile (472 million km) journey. Perseverance will search for signs of ancient microbial life, study the planet’s geology and past climate, and be the first mission to collect and cache Martian rock and regolith, paving the way for human exploration of the Red Planet. Riding along with the rover is the Ingenuity Mars helicopter, which will attempt the first powered flight on another world.

Now that the rover and helicopter are both safely on Mars, what’s next? What would you like to know about the landing? The science? The mission’s 23 cameras and two microphones aboard? Mission experts are standing by. Ask us anything!
