Many people asked the question whether we can live on Mars. In our current state, it wouldn't be possible for humans to live on Mars without some sort of artificial housing. The main obstacles that we have with living on Mars is firstly, the lack of water. Secondly, the soil on Mars is actually toxic for us. And thirdly, the gravity on Mars is less than 40% of that on Earth - it would likely ruin our bodies. And finally, the temperature is freezing!
