Engineers from the American Space Agency recommended the crew to quickly go to the Russian Sightseeing segment and safely wait out the threat there, but it soon turned out that the air was leaking into the abyss of space from this oldest Russian module.
The health and lives of the astronauts were therefore at stake. If the module were to depressurize even more, the astronauts would die almost instantly. Fortunately, nothing like that happened. The crew after a few days found the source of the leak and patched it up. A small hole in the fabric was not created as a result of a micrometeorite impact.
Now, three months after locating the leak, the astronauts are again in danger. Even though the buttonhole has been patched, air is still leaking from the deck. The oxygen leak is not large, about 300 grams a day, but the vision of the inability to patch another hole and further loss of oxygen from the module deck does not fill the optimism of the Russian Space Agency authorities, which plans to organize a supply mission for astronauts.
We can expect that early next year, Roscosmos will send a Soyuz ship to the space home with additional oxygen supplies for the Russian crew. The International Space Station is in Earth orbit, 400 kilometers above our heads, so you can't evacuate astronauts in an emergency in a few minutes.
Experts fear that Russia's ISS modules will soon be struggling with material fatigue. These leaks are an introduction to this. During their construction it was not planned that they would serve cosmonauts for so many years in such inhospitable conditions. We also all remember the last detected hole in the Russian Soyuz, which was accidentally drilled with a drill. The quality of the materials used by the Russians leaves much to be desired.
Such situations show that the future of space missions lies in robots that will detect, for example, the source of air leaks on the International Space Station or spacecraft and quickly neutralize them, all without any participation of astronauts. NASA should take such ideas to heart and start using the power of robots.
