Assuming NASA’s manned lunar mission goes well, we may see a push for human exploration of the Red Planet within 10 years, with a mission starting well as early as the 1930s,media BGR reported. Of course, there are many problems to be solved during this period. The most important of these is the question of where the astronauts will live when they arrive. Now a new study suggests that when astronauts arrive on Mars, there may already be ready-made “homes” as long as they know where to look.
Today’s Mars is cold, dry and relatively quiet, but in the past, mars was much more geologically active. Scientists have seen evidence of huge lava tubes hidden beneath the surface of Mars, where the area where the ground collapses shows how big and wide they are.
When the astronauts go to the moon, they will spend a long time in the spacecraft that takes them to the moon. Eventually, a shelter might be built on the moon’s surface, but for now, NASA just wants humans to explore and retreat into relatively safe spacecraft.
Astronauts to Mars are likely to stay much longer than astronauts on the moon. The journey to Mars is long, and the cost and difficulty of getting the most out of this mission will be unpredictable. It may not be feasible to live in a landing spacecraft for so long. It is also impossible to drag construction supplies to the Red Planet and complete some construction work. Therefore, the natural features of Mars may be the only long-term living option.
In a new paper to be published in the Journal of the Washington Academy of Sciences, researchers explore the possibility of using hollow lava tubes on Mars as a place to live. They made a pretty compelling case, LiveScience reported. One of the greatest dangers for space travelers heading to another world is radiation. We are primarily protected here on the Earth’s surface, but Mars does not offer the same benefits, which means finding a place to escape radiation. Rocks tend to be good at absorbing radiation, and the team tested lava caves on Earth to see how much radiation they can block.
This is not a perfect comparison because we don’t know the exact properties of lava tubes on Mars, but the researchers suggest that Mars caves can block more than 80 percent of space radiation. Astronauts will still receive far more radiation than they do on Earth — especially when they leave “home” to explore the surface of Mars — but that will make the long-term mission more realistic.
