Is Mars Core dead?

With our magnetic field intact, our planet will remain blue and alive for the foreseeable future. But for a smaller world like Mars, its time ran out long ago.

Why can we not live on Venus?

Nothing could live on what passes for land on Venus; its smooth volcanic plains are a scorching hellscape hot enough to melt lead, where the temperatures exceed 800 degrees Fahrenheit. High in the clouds, however, the pressures and temperatures and acidity levels would be less intense — though still vile.

Is it better to live on the moon or Mars?

In the long term, Mars wins. The moon is too harsh to be anything but a stepping stone toward life in space. ... And if something horrific happened on Earth and it could no longer sustain life, Mars would be a much better place to live because of the possibility of finding water, its higher gravity, and its atmosphere.

What are the disadvantages of Mars?

Difficulties and hazards include radiation exposure during a trip to Mars and on its surface, toxic soil, low gravity, the isolation that accompanies Mars' distance from Earth, a lack of water, and cold temperatures.
