In most cases, the search for life on other planets, including Mars, is focused on water, and in the absence of it, hypotheses about the existence of microorganisms are often rejected. Researchers representing the Center for Astrophysics at the Smithsonian Observatory and the Florida Institute of Technology have proposed looking for biological material deep in the bowels of rocky objects in the Universe.
Surface waters require an atmosphere to maintain pressure, because without it liquid cannot exist, but in the depths it is created by the upper layers, explained Associate Professor of Astrobiology Manasvi Lingam. There are no old reservoirs on Mars, but underground lakes are known to exist. There may be traces of life in the compressed and warm areas below the surface. Cryophiles can exist on rocky objects that appear lifeless. These organisms are able to survive and reproduce at very low temperatures. They are found in cold areas of the Earth – in the polar zones and deep in the sea, so astrophysicists do not exclude their presence on Mars or the Moon.
Experts admit that the search for life in the bowels of rocky objects will be technically difficult, but it cannot be said that it will be impossible. An effective way to get into the bowels of Mars or the Moon could be drilling, which is possible in the context of the Artemis mission, which provides for the creation of a stable base on the Moon by 2024. Wells on planets could be made by robots and heavy equipment, as in the search for oil on Earth. If life is discovered, similar principles can be applied to other cosmic bodies.
