ESA is developing stones to build on the moon



A group of European researchers is working with moon dust simulators for the manufacture of stones, which can be used in the construction of habitats on the moon.

For its part, NASA has immediately seen "definitive evidence" of the existence of ice water on the surface of the natural satellite in the "darkest and coldest" of its poles.

Because the surface of the earth and the moon are covered with gray, fine and rough dust, solid blocks can be made to build launch platforms and roads, as well as habitats that protect astronauts from the complicated environment, because of the dust it can be crushed, burnt and compressed, said the scientific advisor of the European Space Agency (ESA), Aidan Cowley.

The European scientific teams see the moon dust as the starting point for the construction of a permanent lunar post, which would be an alternative to stop relying on land supplies.

They claim that the lunar soil is a silicate basaltic material, a common characteristic of planetary bodies with volcanism.

"The moon and the earth share a common geological history and it is not difficult to find material similar to that of the moon in the remains of lava flows," explained Aidan.

As a raw material, similar to the mole, scientists used volcanic dust from eruptions about 45 million years ago in a region around Cologne, Germany.

Research from the European Astronaut Center (EAC) showed that the volcanic dust in that area is a good combination from which the moon dust was made.

The moon dust substitute made in Europe It already has a name: EAC-1. The Spaceship initiative works with EAC-1 to prepare technologies and concepts for future exploration of the moon.

"One of the best things about the lunar floor is that 40 percent is oxygen," Aidan said.

That is why the One Spaceship EAC project is studying how to break oxygen to help astronauts extend their stay on the moon; however, the moon dust is electrically charged, because it is bombarded with constant radiation, causing the particles to release from the surface.

To mimic the behavior of moon dust in a radiation environment, Erin Tranfield, a member of ESA's current moon powder team, mills the surface of the lunar simulators to activate the particles, but the surface properties are erased. "This gives us another reason to return to the moon.

"We need impeccable samples from the surface exposed to the radiation environment," concluded Tranfield.

FIND IN CRATTERS

A team of scientists immediately observed & # 39; final proof & # 39; of the existence of ice water on the surface of the moon in the "darkest and coldest regions of the polar regions", according to NASA on its website.

Most of the newly discovered ice is in the shade of craters, where the highest temperatures are never higher than -156 degrees Celsius, because the small slope of the satellite axis does not allow sunlight to reach these areas.

These deposits are irregularly distributed and "may possibly be old", according to the observations for which data were used from a NASA instrument called Moon Mineralogy Mapper (Moon's Mineral Cartographer), M3.

In the South Pole most of the ice is concentrated in the craters of the terrestrial satellite, while in the North Pole the presence of ice water is widespread, but hardly expanded.

The team, led by scientists from the American universities of Hawaii and Brown, and the NASA Ames Research Center, identified "three specific signatures that absolutely prove that there is ice water on the surface of the moon."

The M3 aboard the Indian moon probe Chandrayaan-1 launched in space in 2008 was specially equipped to confirm the presence of ice on the moon.

This instrument collected data that not only captured the reflective properties expected of ice, but was also able to immediately measure the unmistakable form in which its molecules absorb infrared light, allowing it to distinguish between water, steam or ice.
