Landing on Mars is not easy, especially if the vehicle is a rocket. Indeed, the gravity on the red planet is much denser than that on Earth. It is such a complicated challenge that, of the 40 missions sent by NASA, less than half succeed. Low (and scary) number for anyone ever considering taking people there. Everything indicates, however, that space scientists have figured out how to perform the maneuver more successfully.
For you to better understand the difference between landing on Earth and on Mars, the Digital appearance explains: on its return to Earth, the plane receives here a “help” from the atmosphere, because it is relatively thick and slows down. On Mars, on the other hand, the atmosphere is thinner and the air, on the contrary, denser. For example, Martian air is as thick as Earth’s air at 30,000 meters, more than three times the size of Mount Everest.
“I call it the anti-Goldilocks atmosphere,” said NASA associate administrator Jim Reuter. “It’s thick enough to cause trouble and not thin enough to help you,” he added.
