Russia's cosmonauts spend almost eight hours breaking into spacecraft



On Tuesday, over a period of almost eight hours, Russian cosmonecs Oleg Kononenko and Sergei Prokopyev performed an unprecedented strange space outside the International Space Station.

Both Russians spent about three hours moving across the station, setting up a workstation that they could stabilize themselves and cut into the Soyuz shipbuilder attached to the station. Then, with a number of tools including a knife and a pair of scissors, they turn through a bulk of insulation protecting the spacecraft's orbit module.

The whole procedure was completely exposed, as not everyone sees a person in the space turning through several centimeters of knife insulation. As the cosmonauts take turns working off in the insulation, there were pieces of Mylar and other flash-fired materials off work like dirty snowstorms. (As the station is at a relatively low height, these materials with low mass and a high drag area should be pulled into the atmosphere of the Earth and burn up, with no threat to lighting activities).

Kononenko and Prokopyev worked in the insulation for a few hours, sometimes growing rigidly. Russian translator, speaking on NASA TV, shared a jarring comment between the two gosmons and Roscosmos mission management, located just north of Moscow. "Be careful, my hand is there," the translator would say. And, "Carefully not break the cable." Repeatively, mission management encouraged the difficult hit-taking breaks to take a break. It was wracking to watch the cosmonauts wearing the knife in such a casual manner, so close to their dispersed liquids.

Find the hole

Finally, the crew members switched through the insulation into a thin debris shield, and after removing it, they reached the vehicle of the Soyuz vehicle itself. They were searching for an external site of leakage in the company of Soyuz space found on August 30, about two months after the vehicle washed three members of the crew to the station. Using a number of layers of epoxy resin, astronauts inside the space station cut the slow leak-from a small hole a few millimeters across a day after it was detected. They were never in any serious danger, but the mystery of how the discharge has happened has turned a great deal.

Using a pair of small scissors – an extremely sensitive process with rigid rigid gloves – Kononenko attempted to sample outside the drop-out site that was visually visible in a live video, television. Apparently, taking high definition images and GoPro video from outside the drop-off site and collecting samples of resin or other materials, it will help the Russians decide what it has caused hole to start.

This has been a serious issue for NASA and the Russian Space Agency. Although the Roscosmos leader, Dmitry Rogozin, has been fairly diplomatic on the global stage for the release, in Russia there were amazing rumors that NASA astronauts might be drilled through Soyuz in space, because he want to get back home early.

This is obviously noisy, and the story is much more likely to have occurred in a Russian production facility, with a technician finding the drill mistake and covering the hole with glue. This would have prevented the problem from being detected during a vacuum test. However, this temporary piece could have failed a few months later after a long exposure in space.

On Wednesday, Rogozin thanked the cosmonauts for their hard and successful work in the long run. "I would like to congratulate you on completing the mission successfully," he said. "The space itself, we would say, was uncomfortable in terms of complexity and risks. You cope with her with great success."

Samples collected, said Rogozin, said "is extremely important for completing all the investigation procedures and establishing the spaceship damage cases." Soon they will be analyzed by engineers on Earth.

This could happen as soon as next week, when this Soyuz spacecraft leaves the station with Prokopyev commanding and also carrying German Alexander Gerst along with Serena Auñón-Chancellor NASA. On Wednesday, the Soyuz will move away a safe distance from the station and perform a deorbit burn that will last approximately 4 minutes and 30 seconds, slow down the spacecraft and turn it into the atmosphere of the Earth

Then the orbital module (where the discharge) and the module will fall will be separated by a pyrotechnic of the fall module, which will turn its heat shield into the atmosphere of the Earth and bring & # 39; the crew that samples back to the Earth.
