The space station Mir doom

The space station Mir doom

The space station Mir doom - a strange series of accidents and serious incidents that occurred on the space station "Mir" in 1997. In 1986 he went into space a new station "Salyut-8." The name is remembered only by those who designed and built this house a new generation of space as soon as the station went into orbit, the whole world knew her as "the world".

First change the name of "Salute" - not just a political move perestroika (allegedly attributed the initiative to Gorbachev) is actually the name of the spacecraft largely determined the fate of not only flying, but the crew. Well, almost no breakdowns worked the ships named "Moon," "Venus," "Vega", at the same time not a single unit with the names of the "H", "Mars", "Phobos" is not fulfilled until the end of their program.

In 1994, proposed to rename the machine, "Mars-9" in any other, but the suggested name "Mars-94", then changed because of a delay in the launch of "Mars-96", there was no salvation - in November of 1996, "Mars 96 "happily drowned in the Pacific Ocean.

As for the name "Salute", then bad luck with a few interruptions pursued these stations from the outset, the most numerous in the Soviet history of the death of the astronauts (crew Dobrovolsky, Volkov, Patsaeva) occurred immediately upon return of the first expedition from the first "Salute."

Station "Mir" ("Salyut-8") was an improvement over all civilian versions of "Salute" (including the deceased, "Salyut-2"), but the fate of its radically different from previous ones.

The name of the "world" out of luck. In the sense that the adventures and misadventures on the "World" was more than ever before in the history of space exploration, but they all ended peacefully.

In April 1987, at the day of space for the first time in history was to dock ships are literally hands astronauts had to pull the bag outside of the docking station, why was it necessary to push a hand in 20-cm gap, the risk of being caught between two 20-ton bulks.

So with great difficulty, managed to attach to the "World"-W module "Kvant". As it turned out, the name "Quantum" is also applied to the category of not very successful, after a short time-D module "Kvant-2" is also experiencing the same difficulties, the approach of the base unit, and again the heroism of the astronauts module saves from MCC offers flood insubordinate module in the ocean.

When preparing for the start of the third module, a very nervous atmosphere of waiting time someone offered to get rid of the names and compromised T-module "Kvant-3" flew to dock when he was known worldwide as the "Crystal". Docking was great! But the old "maiden" name still haunt.

In January 1994, the crew of "Soyuz TM-17" circling the station for visual inspection and is close to that of the module "Crystal", I suddenly felt as their ship was the twist angle of pitch. Why give automatic control failure and why it happened in this most dangerous time - to establish so far failed.

Perhaps the technology is out of control and some sort of oversight allowed the cosmonaut Vasily Tsibliyev, at least in the public domain was made at the time recording of conversations between him and sitting for a laser rangefinder, Alexander Serebrov.

At the time of the accident dialogue is replete with official Russian unprintable expressions and can be reduced in general to one question: "... Where ... you ... rulish ...?" But then there was no time to argue and crew as soon as I could, switched to manual control. Of course, the moment was lost and "Union" nevertheless hit the "Crystal" its most vulnerable part - the lander.

Hold still for a moment astronaut - and the impact would be stronger.

And then - or there would be a depressurization (although the astronauts were ready in their space-suits), or would have damaged insulation sheathing, SA, which certainly would not stand if the fiery descent into the atmosphere and would make the two crew members in a handful of ashes. This incident went down in history forever as the world's first collision of two vehicles in space. Down and Out trouble started.

The world's first serious fire in space occurred on the "World" after 3 years, in February 1997. More precisely, the central unit is not burning, "Peace," and all that the same ill-fated first "Quantum". And this time Russian boys in the space not taken aback, and let (first time!) In case fire extinguishers.

Smoke was not too big, but because of the fact that the air station is located in a confined space, had to walk all day long (ie, fly) in respirators and kept burning smell even after a few weeks.

The astronauts - people are grateful, and they certainly have remembered a good word for the late designer Queen, who is full of their savior. When at the dawn of space exploration, when only the basic outlines were drawn manned spacecraft, Korolev strongly advocated the complexity of life support, although he was tempted to build cabins in all apparatuses oxygen atmosphere - and easier and easier, by weight, and reliable in operation, and pressure in the cabin reduces to a minimum.

Americans have chosen this, but knew the only negative of such a decision - in pure oxygen fire could arise from any sparks.

He appeared at the first opportunity, killing three crew members of "Apollo" (they had not even had time to reach the extinguisher useless). A little later, fire was the "Salute", the astronauts in a panic like to leave the station, but academic Mishin then right now - come back, removed the accident and continued to work.

If the "World" was not an oxygen-nitrogen "earth" mixture of gas and pure oxygen, the station immediately would become the world's first crematorium in orbit, to extinguish the fire which is impossible in principle. Is that by depressurization ...

And the world's first manned compartment depressurization occurred also in the "World". On the afternoon of June 25, 1997 happened to the world's second collision in space, the second time at the helm of the ship-ramming was the same astronaut - Vasily Tsibliyev.

The case is doubly rare - of hundreds of Russian pilots survived only a few rams ramming two of hundreds of Japanese kamikaze - none at all, but here - 2 ram in a vacuum - and get away with slight shock, reprimands and temporary suspension from work! ..

But the accident has begun long before that - it was scheduled when the union began to unravel the relationship between Russia and the independent Ukraine, which were previously produced some of the details of "course" - the one that provided a hitherto rendezvous and docking of ships in space.

"First call" sounded on March 4, when re-docking failed "Progress M-33". Who brought supplies from the Earth "Progress" undocked from the station and took him to temporarily release the docking station for the "Soyuz TM-25", but with two attempts to return back to the truck were not able to suffer with him enough, simply drowned in the ocean together with such necessary for astronauts reserves of fresh water ...

The cause of failure with thirty-third "progress" have decided to find with the help of the thirty-fourth "Progress" and ... failed again! Truck was taken from the station, passed away a hundred yards and broke up again in the direction of the complex.

Thought that the scatter in the experimental training dock and it turned out - dispersed to ram! The aim was to get to the docking bar "Progress" in the docking funnel with a diameter less than a meter, at such speeds - a problem jeweler, but repeated many times in practice.

For a few hundred cases of successful dockings were only a few misses, but always electronics displays errors, and the ships have time to brake before the kerf in the side wall or end of a docking station.

Piloted remotely truck Tsibliyev realized that misses the mark and gave the command for braking ... However, he realized that a little later than it would if it could see standing on the "Progress" system "course."

"Thirty four" could inhibit about 30 meters, but ... did not do it ... perhaps because the antenna, which passed on the team with the "World" to the inhibition was at that time may have already escaped the body of the "World."

"Progress M-34" hit the module "Spectrum" (formerly "Quantum-4") at a relatively low speed. Aerial truck struck a silicon elements Sat, truck flew off to the side, hit the radiator cooling, re-touched a solar panel and only then otfutbolilsya aside.

The American crew member of the "World" Michael Foale did not even feel a push (in his words). However, the impact has been on one of the most vulnerable - on the solar farm, which is like pulling a big powerful arm, could turn out anything "with meat".

Drawn by the mass of the ship-ramming solar panel inversion of the shell casing of the module its own mount. Hole! In the resulting crack area not more than 4 square centimeter immediately poured into the air, Tsibliyev and Lazutkin heard a whistle (the noise of the fans it was not easy) and rushed to the bay!

Required the most urgent action by going on a second. Since plug a hole was not possible to sacrifice space was brought to a section - one of 6 units of the orbital complex.

Slam sealed the hatch quickly at the old station is almost impossible (pass through manholes over time thrown over the wires and hoses), but two Russian crew members worked smoothly - and closed the door on time, because they have not been able to seal the end, as in a segregated unit was already cold space and vacuum.

His breath, trudged astronauts to Earth to report on what happened. In addition to the loss of sixth volume of the station, she at once lost and a third or even half the energy - the cables from the SB "Spectrum" in a hurry when disconnected zadraivanii hatch ...

In spite of the old building (in some places - thinner cardboard), and despite all the vicissitudes "World" continues to watch. More and more time is needed to maintain it in working condition.

Astronauts have to manually manage the station because of the periodic (strictly on-Monday) failures on-board computer, get through the smallest snake in the gap, eliminating leaks in the thermal block "Quantum", and while they do not fully done, the temperature in the same " Quantum "is like a bath.

Not with water vapor, and with an alcoholic - from leaks to the atmosphere PAGE station escapes nothing, as industrial alcohol. Make repairs in such a heady and knocks down both the hot and the atmosphere can only goryachitelnoy Russian part of the crew ...
