Can humans live on Callisto?

As a result, humans could live on the surface of Callisto with just a sufficiently strong radiation attenuating glass between them and the remaining radiation from its host planet. In addition to this relative safety from radiation, this moon is composed of around 40% water.

Is Callisto a dead moon?

But data from NASA’s Galileo spacecraft in the 1990s revealed Callisto may have a secret: a salty ocean beneath its surface. That finding put the once seemingly dead moon on the list of worlds that could possibly harbor life. Callisto was discovered Jan.

Has NASA landed on Callisto?

What is the safest planet?

Besides Earth, Mars would be the easiest planet to live on. Mars has liquid water, a habitable temperature and a bit of an atmosphere that can help protect humans from cosmic and solar radiation. The gravity of Mars is 38% that of the Earth.

Which is the most habitable planet after Earth?

Pluto-Charon is our solar system’s only known double planetary system. The same surfaces of Charon and Pluto always face each other, a phenomenon called mutual tidal locking.
