When I will be almost 80 i will go to mars with my family biggrin

I realy like that in mars you can do most of things that you can do on earth



This is awesome, imagine if it was real right now, you could find people on social networks or any other things that live on "Mars", that would be very odd xD

Mars is very dangerous for asteroids, there is no dense atmosphere that can stop the smallest asteroids, a big sand storm could destroy all us "houses" D:

I guess you mean "meteorites". Asteroids couldn't be stopped even by Earth's atmosphere (and even by Venus').

No, it couldn't. Martian atmosphere is 60 times less dense than ours (1.225 kg/m3 vs 0.020 kg/m3), this means a dynamic pressure of 100 m/s (360 km/h) wind on Mars is the same as 13 m/s (46 km/h) wind on Earth.

It's difficult to say what is an asteroid and what isn't... how small does something have to be before it is not considered an asteroid anymore? Is an object 10 meters wide an asteroid? That would easily be stopped by Earth's atmosphere. So drawing the line between asteroid and meteoroid, and meteoroid and dust is not very simple. Mars' atmosphere can block small meteoroids though, just as Earth's can.

No. The materials that Martian habitats would be made out of would likely be similar to materials that would be used to make other space habitats, which are designed to withstand impacts by micrometeoroids and orbital debris. Even the most violent sand storm would pose no risk to the shelter at all.

In Russian tradition, boundary passed somewhere around 10-50 m radius. Tunguska was nearly 50 m and considered as meteorite though.

That sounds like a reasonable size cutoff.

By the way, just for everyone's benefit, I'll define what some of these terms mean:

  • Comet - Irregular object in Solar orbit >10 meters size made mostly of rock and volatiles
  • Asteroid - Irregular object in Solar orbit >10 meters size made mostly of rock and metal
  • Meteoroid - Object between 100 µm and 10 meters size
  • Micrometeoroid - Object <100 µm in size (includes interplanetary dust)
  • Meteor - Any natural space object after it has entered an atmosphere
  • Meteorite - An asteroid/comet and its remains after it has collided with the surface of another object
