NASA’s Mars 2020 Perseverance rover mission is just 22 days from landing on the surface of Mars. The spacecraft has about 25.6 million miles (41.2 million kilometers) remaining in its 292.5-million-mile (470.8-million-kilometer) journey and is currently closing that distance at 1.6 miles per second (2.5 kilometers per second). Once at the top of the Red Planet’s atmosphere, an action-packed seven minutes of descent awaits – complete with temperatures equivalent to the surface of the Sun, a supersonic parachute inflation, and the first ever autonomous guided landing on Mars.
