The plunge through the martian atmosphere will heat Perseverance’s shielding to temperatures up to 1300℃.

It’s time to land a car on Mars. After 6 months of flight, 8 years of planning, and decades of scientific desire, NASA is set to put the Perseverance rover on the surface of the Red Planet. If success comes tomorrow, it will mark the first chapter of an audacious scientific campaign to drill and collect samples—and bring them back to Earth. But before the mudstone can be drilled, and before an onboard helicopter can fly, the $2.7 billion rover must first safely land at Jezero crater, which billions of years ago contained a lake and a river delta—auspicious places to look for life.
