How would the size of the parachute required on a space probe to allow it to land safely differ on a planet such as Mars which has a thin atmosphere?
Answers
Two reasons. The atmosphere is too thin to slow the descent for a soft landing. Mars is almost a vacuum, it is the equivalent to Earth atmosphere around 125,000 feet. ... You do not want your lander to get entangled with the chute on landing, so you loose the chute right before you land.
✎ The skies off the Hawaiian island of Kauai will be a stand-in for Mars as Nasa prepares to launch a saucer-shaped vehicle in an experimental flight designed to land heavy loads on the red planet.

But Nasa needs a bigger and stronger parachute if it wants to send astronauts there.
