Hidden Lava Tubes on Moon and Mars can serve as Human Colonies

Scientists claimed that lava tubes that mean the underground caves created by volcanic activity, found on the moon and mars.  These lava tubes could serve protected human habitats to house streets, residencies or towns on the moon and mars.

The similar lava tubes have been detected on earth in many volcanic areas including, Iceland, Sicily, Hawaii, North Queensland in Australia and the Galapagos islands.  There’re two teams of scientists working on an operation to use the lava tubes on the moon and mars that can reach up to 65 kilometers.

Space missions have detected chains of collapsed holes and ‘skylights’ on the moon and mars and according to them the evidence considered as Lava tubes.

The comparison of lava tube of the earth, moon and mars were carried out by the researchers from the University of Padova and the University of Bologna in Italy. The research was conducted using high-resolution digital terrain models (DTM) which were created using spacecraft instrumentation’s data.

“The comparison of terrestrial, Martian and lunar shows that, as you might expect, size of the lava tubes highly get affected by the gravity. On Earth, they can be up to 30 meters across. In the lower gravity environment of mars, we see evidence for lava tubes that are 250 meters in width. On the moon, such tunnels could be a kilometer or more across and many hundreds of kilometers in length,” said Riccardo Pozzobon, from the University of Padova.

The lava tubes can form in two ways: through the crusting over of lava channels, or by developing a hard crust that generates pahoehoe above the moving lava stream. Lava tubes are protected from micrometeorites flux and they are big sufficient for human settlements.
