As you can see above, this is Mars. But it's not Mars. It's a fake dimension in USA, (Utah). No human body has ever set foot on Mars and made it out alive. Gravity will cause death to humans because they would get hit by rocks and natural environment. But no, in reality you could survive on Mars, but you'd have to take one hell of a fast rocket ship (Faster than the New Horizons Rocket Ship). Mars is very, very far away from Earth, millions of kilometers, 54.6 million to be exact but the point is, Mars is very far away. Wearing a space helmet and having a super fast rocket ship, you might make it to Mars!
Good luck!
