Space: Reveals how to build a colony on Mars. "Silica Aerogel"

Silica airgel is slotxo a translucent material. It contains 99.8% air and is the lightest solid in the world.

Humans are planning to colonize Mars in the next few decades. But the big problem, besides traveling There is also the matter of the extremely dry and cold Martian environment. not suitable for living things This led scientists to try to figure out how to terraforming, which is to create and modify the atmosphere of Mars all along.

Recently, a team of NASA scientists has proposed a new method. This will warm specific areas on Mars. until water can remain liquid on the surface of the stars by using sheet material "Silica Aerogel" (Silica Aerogel) covers a small area that would be a pioneering site for human colonization first.

The research paper, published in the journal Nature Astronomy, states that silica airgel is a translucent material. It contains 99.8% air, is only twice the density of air, and is the lightest solid in the world. The grip feels like plastic foam or styrofoam.

When covering an area of Mars with a sheet of silica airgel, it creates a "Solid-State Greenhouse Effect" in that area. The translucent material traps solar heat inside and transmits it downwards. warm the area The surface of the aerogel, which contains silica fibers, also reflects harmful ultraviolet rays.

NASA's team of scientists said that A few centimeters thick sheets of silica aerogel are needed to raise the temperature in the Martian colony by 50 degrees Celsius, hot enough to allow water to remain liquid on the planet's surface and drinkable. edible
