Why Is It So Difficult To Land On Mars?
The atmosphere of Mars is a hundred times thinner that Earth’s. This makes parachutes ten times less effective which means that if you were to skydive on Mars, you would be falling at 200MPH. To lessen this speed, NASA increases the size of the parachute. The Curiosity rover used the largest supersonic parachute in 2012 but even that didn’t slow it down enough.

So How Do We Do It?
AdvertisementThe alternative to this is a carefully crafted process. First, the spacecraft deploys a huge parachute to lessen the speed. Next, it fires retro rockets to take it the rest of the way. Timing is very crucial here. If the parachute or the rockets don’t keep time as planned, the end result is disastrous.
So far, only three space agencies have tried to land on Mars. NASA, The European Space Agency and the former Soviet Union. None of them have the perfect record. So why do we keep trying to land on Mars? Maybe because it’s close to Earth and we can discover alien species or other forms of life, or it’s because of the fact that we might just be the first species to inhabit another planet other than our own.
