The landing of NASA's next Mars rover is now just days away.

The car-size Perseverance rover, the centerpiece of NASA's $2.7 billion Mars 2020 mission, will hunt for signs of ancient life, collect and cache samples for future return to Earth and help demonstrate a variety of new exploration technologies, among other tasks.
