As major worldwide problems such as climate change + global warming, global dimming, global water pollution, global air pollution, global education deficits make more effect on Human race, it is time to find other habitats suitable for human living. Could Lunar Shelters solve this problem ? Nasa has been working on since 2009 on these Lava tubes as possible solutions for human colonization the activity has picked up in recent years from other space capable nations interested. Does it solve huge population problems in places like South Asia, SE Asia, SSA etc... ? Do we have have an answer for all the civilization extinction ?





Moon's surface is battered by millions of craters, it also has over 200 holes – steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft.The pits range in size from about 5 meters (~5 yards) across to more than 900 meters (~984 yards) in diameter, and three of them were first identified using images from the Japanese Kaguya spacecraft. Hundreds more were found using a new computer algorithm that automatically scanned thousands of high-resolution images of the lunar surface from LRO's Narrow Angle Camera (NAC).


The two GRAIL probes precisely mapped out the moon's gravitational field from orbit from March 2012 through December 2012. Because gravitational pull is related to mass, a hollowed-out region such as a lava tube tugged at the spacecraft slightly less than did solid ground.Next, the scientists searched the lunar mare for signs of lava tubes with no visible surface features. They found at least 10 large candidates, some nearly 1 mile (1.6 kilometers) wide and stretching over 60 miles (100 km) in length.


Mike Dunn talked about the use of lava tubes for the Moon and Mars habitats. Mike has worked on The Mars Lava Tube Pressurization Project’s (MLTPP). The lunar soil is 40% oxygen. Lunar cement could be made to block off and enclose a lava tube. This would make it hundreds to thousands of times easier to make safe and large habitats on the moon.

Lava tubes could be enclosed and pressurized to support facilities such as greenhouses and maintenance enclosures. Astronauts could also use inflatable tents inside of lava tubes and caves while being protected from temperatures, radiation and meteorites.
They are working to simulate Moon and Mars lava tube habitats in a lava tube in Iceland.

Probably places like The Marius Hill Skylight and Tranquillitatis Pit are both near Titanium, iron, water and helium 3.

Reconnaissance phase technologies may include EVA suited rappelling techniques and astronaut jetpacks. Possibly a quadruped robotic “pack mule”, Multi-Utility Legged Explorer (MULE™) would carry equipment for astronauts.
