Turns into a disaster the launch of cargo transport vehicle of new generation “Progress MS-04″ to the International space station was the first major failure of Russia in space over the past year and a half. Four days before Deputy Prime Minister Dmitry Rogozin announced that Russia broke “the shroud of defeat, hurtful accidents and disasters”. What happened with “Progress” and what that means, to understand”.ru”.
the launch of the “Soyuz” and “Progress” took place at the Baikonur cosmodrome at 17:52 Moscow time. Start of the carrier rocket and the separation of the first two steps were successful. It was assumed that the ship will spend in Autonomous flight for two days. Docking with ISS is scheduled for 19:43 Moscow time on December 3.
Later 383 seconds after launch in Roscosmos reported on the loss of telemetry, and staff means of verification have not found the ship in orbit. The connection was lost when the ship was at an altitude of about 190 miles above the desolate mountainous terrain of the Republic of Tuva. “Progress MC-04″ failed to reach orbit due to the fact that the rocket did not gain sufficient speed. The ship was destroyed when entering the dense layers of the atmosphere.
On Board the ship was about 2.5 tons of various cargoes for the crew members of the 50th long-term ISS. In addition to food, water, air, various packages and other means of life support of cosmonauts and astronauts, “Progress MC-04″ was supposed to deliver fuel to the space station. In addition, the ship was carrying a greenhouse “Lada-2″ for the cultivation of sweet pepper, wheat and lettuce in microgravity, and also the first instance of a new generation of spacesuit “Orlan-ISS”.
According to preliminary data, the damage for the “Roscosmos” from the loss of “Progress” may exceed four billion rubles. The launch was carried out on budget, and fully damage insurance will not cover. Some experts hurried to find in the crash of the Ukrainian track — was allegedly the fault of a control system made according to preliminary data, the Kharkiv state scientific production enterprise “Kommunar”.
a Source in space industry said “the Tape.ru” that the cause of the incident could be the failure of Roskosmos from a modern carrier rockets “Soyuz-2.1 a” in favor of obsolete modifications of the “Soyuz-U”.
“the pace we will run our “Advances”, and we can’t do it without the help of the Americans: after the loss of the cargo ship in April 2015, we were forced to go with a modern vehicle “Soyuz-2.1 a” on old and proven “Soyuz-U”. Now with him, think problems,” the source said. He also noted that to draw conclusions and to identify the perpetrators is premature.
Source “Tape.ru” referring to an accident that happened a year and a half ago, on the morning of 28 April 2015. Then launched to the ISS using rocket “Soyuz-2.1 a” truck “Progress M-27M” at MCC also no longer receive telemetry data. Roskosmos said that puts the truck dock with the ISS on a two-day scheme. During the day the Ministry did not give clear comments. Meanwhile, closer to the evening of April 28 “the Progress M-27M” entered uncontrolled rotation, and the next day the US air force has recorded in orbit next to the truck debris of unknown origin.
“Progress M-27M” began an uncontrolled deorbit, and may 8, the pieces of the truck (which, incidentally, is supposed to deliver to ISS the Flag of Victory) fell into the Pacific ocean. It made a lot of noise in the network, and in the space Agency was quick to say that the Victory Banner was already delivered to the station. Cause of accident experts named design features sharing rockets and truck — in other words, separately they were OK, but their joint work was not coordinated. In this case, it is likely that depressurization of fuel tanks of the third stage.
This failure has forced Russia’s Roscosmos to send the trucks in modern rockets “Soyuz-2.1 a” and the carriers “Soyuz-U”, which are considered the most reliable in the world. However, they are used too long, since 1973, so in 2017 there were planned last flight. And even improved versions of trucks “Progress MS” was run on the same “Soyuz-U”. But the “Soyuz-2.1 a” forgot — it, adapted for a new launch pad variant was launched from the Baikonur East in a year after the disaster, 28 APR 2016. Then, too, not without overlaps — start, scheduled for April 27, was postponed for a day due to a malfunction in the power control system of the missile.
the Failure was caused by negligence in the manufacture of the cable leading to the fuel valve. The General Director of the Ekaterinburg NPO Avtomatiki, Leonid Shalimov received a warning about incomplete official correspondence from President Vladimir Putin and resigned. The head of state called the incident “a perfect example of sloppiness”. The head of Roscosmos Igor Komarov and Vice-Premier Dmitry Rogozin escaped with a reprimand.

ironically, Rogozin four days ago, 28 Nov 2016, managed to declare that “the Russian space program, having escaped from the shroud of defeat, hurtful accidents and disasters, to stabilize the quality made a qualitative leap forward in the creation of new technologies.”
the situation Today is almost exactly reproduces the events on 24 August 2011, when part of the third stage rocket “Soyuz-U” has an accident with a truck “Progress M-12M”. “Then at 325 seconds violation occurred operation of the propulsion system that led to its emergency shutdown. Fragments of the space truck, not burned in the dense layers of the atmosphere, fell in the Altai mountains. Victims and destructions on the earth was not” — said the source RIA Novosti.
According to him, everything was regular up to the plot of the third stage, 309-th second of flight. 16 seconds after the start of the third stage disrupted the work of the RD-0110, and after another 33 seconds. he alarm went off. The third stage of the rocket with neuroaminidase from her ship “Progress M-12M” on a ballistic trajectory entered the atmosphere and disintegrated.
the Reasons for the emergency situation became clear almost immediately to the violation of the conditions of work and lower parameters of the RD-0110 and its emergency shutdown caused reduction in fuel consumption in the gasifier due to clogging of the path of its submission. The Commission recognized identified a manufacturing defect random, that is, an isolated incident that will not recur the next time the launches of “Soyuz-U”.
the outcome document of the interdepartmental Commission on investigation of the accident on 24 August 2011 refers to the need “to develop and implement additional control measures condition of units of new engines in the process of their development and manufacture, including install video surveillance systems at workplaces in the shops final Assembly”.
“Random manufacturing defect is not due to violations of the technological cycle, and individual factors that, in General, should not be, but may occur in production. The competent Manager is to avoid such accidental defects, they have no place in the industry. If the random defect has arisen a second time, he should be classified as a manufacturing defect. But again, too early to draw conclusions”, — said the source “Tape.ru”.

Now to deliver cargo to the ISS only Russian “Progress”, private American truck Dragon (company SpaceX) and Cygnus (Orbital ATK) and Japanese HTV. Dragon is the only space cargo ship capable of returning cargo from orbit to Earth. The rest burned along with the waste in the planet’s atmosphere. Investigation of the causes of what happened will surely take some time to hurry in this matter would be crazy. While Russia can use the help of ISS partners.
the Closest launch to the ISS should take place through the week, 9 Dec. To the station for the sixth time to get a vehicle HTV, the Japanese space Agency.
