Any such harm would make the study of Mars (which had liquid oceans for a billion years) much harder, if not impossible.Mars would never be the same again—the irreversible move needs to be extensively debated before it is too late.We have so far identified—let alone DNA-sequenced—a very limited share of the Earth’s microbial world.

No matter where Earth microbes would be released, they would reach potential habitats in a matter of years, or decades at most.

The iron oxide found in the dust would actually protect microbes from UV radiation.

Long-term habitation on Mars will require us to master the conversion of raw Martian materials into resources we can use to survive.

Fortunately, Mars has a wealth of these materials, making it arguably the most human-habitable place in the solar system, other than the Earth itself.

Mars is a dry planet compared to the Earth, but compared to other celestial bodies like the moon and asteroids, its water budget is quite generous.

Mars has a polar cap composed of a mixture of water-ice and CO The greatest physiological obstacles currently standing in the way of extended habitation of the surface of Mars is arguably not radiation, but the fact that analysis of the Martian regolith by NASA’s Curiosity rover indicates the regolith is, by weight, composed of about 1 percent toxic Cl O, otherwise known as perchlorates.

Our microbes could possibly then share genes with some potential Mars life (if they share a common ancestor), which would completely confuse our search.

Their amino acids would get mixed up with current Mars life (if any), remains of past Mars life (if life ever arose there) or any pre-biotic chemistry on its way to life.

If Humans go to Mars, they’ll have no choice but to bring with them their microbes — this is inevitable.

For a start, there are more microbes in our body than even body cells — and we’re not even counting microbes in the air we’ll breathe in the ship and on the Mars base.
