On the one hand, I know this sort of thing is necessary if we are ever to travel across the galaxy…

If all goes as planned, the Perseverance rover will touch down in the red planet’s once-wet Jezero Crater next February. In addition to deploying a helicopter named Ingenuity and generating oxygen from Mars’s thin, 95 percent carbon-dioxide atmosphere—a useful proof of concept for future crewed missions to Mars—Perseverance will spend the next couple of Earth years searching for biosignatures, or signs of ancient life that thrived before most of Mars’s atmosphere was lost to space and its liquid water boiled away. A decade after the rover starts rolling, NASA hopes, another spacecraft will carry rock and soil samples collected by Perseverance back to Earth for further analysis.
