Meteorites discovered on the floor of Mars could include fossilised proof of life – which may very well be investigated by present and future rovers on the Red Planet.
When meteorites fall on Earth they’re identified to expertise fast contamination by microbes. These can depart telltale markers of their presence behind. For occasion, some could burrow into the meteorite and create microscopic tunnels. Others may subtly change the chemical composition of the rock. But it was unclear how efficiently meteorites may protect this proof. …
