IS THERE ANYTHING ON EARTH THAT COULD WITHSTAND CONDITIONS ON MARS?
BBC Science Focus
|Summer 2025
Mars is a pretty horrible place for any creature used to life on Earth. The average surface temperature is -63°C (-81°F) and doesn't reach above freezing anywhere except right on the equator, during the summer.
The atmospheric pressure is equivalent to Earth's at an altitude of 35km (almost 115,000ft) - well above the cruising altitude of commercial aircraft. And this thin atmosphere is nearly all carbon dioxide, with just the merest trace of oxygen. Then there are the radiation levels, which are 400 times higher than on Earth, plus the lack of liquid water anywhere, except for occasional, very salty, trickles.
