The new findings say that the hidden lava tubes, i.e. the underground caves that were created by the volcanic activity happened ever on the moon and Mars can be served as the human habitats, which are enough large to colonize residencies, streets or even towns.
According to the scientists, in future, these gigantic underground caves may provide a meteorite strikes to the astronauts as well as a natural shelter against the cosmic radiation for the residents who will be setting up colonies there on the moon.
There are two different groups of scientists working on a task to exploit the lava tubes on the mars and moon that can reach up to 65 kilometer. The similar lava tubes have been discovered on Earth in many volcanic areas including Iceland, Hawaii, Sicily, Galapagos Islands and North Queensland in Australia.
The researchers from University of Bologna and University of Padova in Italy have conducted the first systematic comparison of these lava tubes on the Moon, Earth and Mars that will be based on the high resolution Digital Terrain Models (DTM) which is created by using the gained from the spacecraft instrumentation.
Riccardo Pozzobon from the University of Padova stated that, “The comparison of terrestrial, lunar and Martian examples shows that, as you might expect, gravity has a big effect on the size of lava tubes. On Earth, they can be up to thirty meters across. In the lower gravity environment of Mars, we see evidence for lava tubes that are 250 meters in width. On the Moon, these tunnels could be a kilometer or more across and many hundreds of kilometers in length.”
