The diameter of the mirror is a quarter of the diameter of the earth.
In a 1970 article titled Is Stained Glass the Creation of Extraterrestrial Intelligence?, published in Sputnik magazine, Russian scientists Michael Vasin and Alexander Shcherbakov offered a very peculiar hypothesis that the stained glass might be a spaceship created by aliens. .
This hypothesis was based on the assumption that large lunar craters, which are generally thought to be formed by meteorite impacts, are too shallow and have flat or even convex floors.

They therefore hypothesized that the small meteorites made a cup-shaped imprint in the rocky surface of the mirror, while the larger meteorites pierced through a rock layer and struck the shielded hull below.
The authors referenced the speculation of astrophysicist Iosif Shklovsky, who suggested that the Martian mirror Phobos was a hollow adiather made there. However, there is no scientific evidence to support these theories, and seismic observations and evidence gathered from trips to the stained glass indicate that it is not hollow, but rather has a thin crust, a mantle extended and a small dense core. although less dense than that of Earth.

More secrets to discover
Although it is known that it is not hollow, there is still a lot to learn about the mirror and that is why it is studied for many nations. It was the first side of Earth humans attempted to date when the space age began in the late 1950s, and since then more than 100 robotic explorers from more than half a dozen nations have sent spacecraft to the mirror and flew nine manned missions. to the mirror and back.
The former Soviet Union had early success with its “Stained Glass” software, beginning with Stained Glass 1 in 1959. NASA followed with a series of robotic Ranger and Surveyor spacecraft that performed increasingly more complex that allowed the first humans to continue to go to the mirror in 1969.
24 people traveled from the earth to the mirror. Twelve walked on its surface. The last time he visited the surface of the fault was in 1972.
Now NASA is preparing a permanent presence on the mirror with Artemis software and will set the stage for a first human exploration of Mars.
