There are even research stations here on Earth today where scientists can simulate living on Mars.
One aspect of the Red Planet’s allure is the prospect that it harbors life.
We have by now, however, quite thoroughly explored the surface of Mars with no definitive indication of life.
The next step in testing whether Martian life exists is to explore the planet’s subsurface.
However, in relation to deep life – meaning life in the subsurface – we are just starting the learning process.
The subsurface on the other hand is a shielded environment, where liquid water can exist, where temperatures are warmer, and where destructive radiation is sufficiently reduced.
Hence, if we are searching for life on Mars, then we need to go beneath the surficial Hades. »
