When cosmonauts work in space they work in a weightless environment. It goes without saying that they need to be prepared for such work. But how can it be done on Earth? It's not as hard as it first seems. Conditions closest to weightlessness are provided by ordinary water. That is why in 1980 they
built a water immersion facility in the Cosmonauts Training Center named after Yuri Gagarin. For the thirty years of its existence cosmonauts have spent over 65 000 training hours here, those who have subsequently walked in real space had the same opinion: it felt 95% the same.
Even in our age of developed industrial technologies the appearance of the larger man made objects being assembled out of steel touches me, when the people working on the ship or submarine are hundreds of times smaller than the metal giant they are building. So I can imagine how impressive this was a hundred years
ago when it was fresh and those achievements of human engineering were just popping up for the first time. Building something half the size of the Titanic in a wooden barn really should look tremendously awesome for the ones who could take a peek inside. We can take a look inside, too.
In Russia, some people say the city of Karabash is the blackest point on the planet. As Dmitrij, the photographer writes: "Karabash is Southern Uralian Mars. It has all the signs of an extraterrestrial place - dead soil, covered with cracks, a river with its reddish-yellow waters with no signs of life and black artificial mountains." Then he
explains that the reason for all this is a large copper molding factory which has poisoned the local nature for years. He says that in the 1990s the city was called the most polluted city on Earth and acknowledged as a real catastrophic site. Here are a few photos of the place taken by Dmitrij with his flying drone:
