Imagine yourself on the surface of Mars. The temperature is a balmy zero degrees Fahrenheit. The pink, nearly cloudless Martian sky surrounds a tiny but blindingly bright Sun, shining its feeble light on the frigid surface. In other words, it’s a beautiful day on the Red Planet.
Suddenly the sky opens up in a fiery and terrifying display. What can only be described as a creature from another world begins a rapid descent to the Martian surface. In the space of seven minutes, what was a speck of fire in the sky becomes an enormous robotic vehicle firmly planted on the surface of Mars. It promises quite a show.
First a parachute catches as much of the thin Martian air as it can, slowing the body of the craft down from a blistering 900 mph to a still-deadly 180 mph.
