“Messenger” flew to Mercury in 2011

The American space probe “Messenger”, who spent four years in orbit around Mercury, and more than a decade in space, down to the surface of Mercury, the press service of NASA.

The operation went according to plan. The unit mass of 513 kg, which spans only 3 meters, crashed into the planet’s surface at a speed of 14,000 kilometers per hour, resulting in the Mercury formed a new oval crater the size of a tennis court.

According to the NASA’s report, in the center of the flight control another 20 minutes recorded signals from the device, but this was due to too great a distance from the Earth to Mercury.

In 2011, the “Messenger” went into orbit around Mercury, where he was to stay, according to the plans of NASA, during only a year. His last fuel was spent on translation maneuver into an elliptical orbit on April 24.

As a result of the collision with the surface of the planet, “Messenger” was completely destroyed. The probe could crash into Mercury due to the fact that this planet is not dense atmosphere, which could burn the “Messenger”.

The mission of “Messenger” was extended twice, and during this time the data transmitted by the probe to the Earth, changed our understanding of Mercury.

“Messenger” NASA sent 270,000 photographs and 10 terabytes of data.

“Messenger” sent to Earth images of Mercury’s unique

Among other things, that “Messenger” found that craters at Mercury’s poles have ice, but also found that the magnetic field of the planet is not focused on the center of the planet, and rejected by 10% of the planet’s axis of rotation.

For four years, “Messenger” circled the Mercury 4104 times in an elliptical orbit, approaching the planet at a distance of 96 kilometers.

Fall

To maintain this orbit, despite the attraction of the sun, every few months, “messenger” had to include its engine, thereby using the last of his fuel.

During the penultimate rendezvous with the planet, “Messenger” flying over the surface at an altitude of 300-600 meters.

“Messenger” showed signs of volcanic activity on Mercury in the geologically recent past,

Eight hours later, the probe crashed into Mercury. The exact path was calculated using data collected by the “messenger”.

The surface of Mercury is full of huge rocks, but the collision had happened to her, as was intended, at a fairly flat plain near the crater with a diameter of 370 km of Shakespeare, which remained after the fall of the ancient asteroid. The blow was a very acute angle.

The fall happened on the side of the planet facing away from Earth. This means that communication with the device at that time was not, and more than a thousand images of the last unit took with him to the grave.

“messenger” was able to study Mercury in great detail, which is not expected NASA specialists.

Many believed that he did not fly to the Mercury, not to mention the fact that the probe will go into orbit around the planet, and will collect data for four years, instead of the planned year.

But the “Messenger” will continue to help science and after his fall. He created a 16-meter crater on Mercury’s surface would be eroded due to cosmic radiation and downs of small meteorites. Such erosion craters makes darker.

By 2024 Mercury should arrive European and Japanese probe “BepiKolombo” that can measure how much darkened crater left by the “messengers”, so that scientists can better understand the process Space erosion.

Obtain unique images of Pluto – Utro.Ru

With the US space probe New Horizons, which made the first in the history of space exploration trip to the Pluto , the Earth passed color photos of the dwarf planet. The photos were taken with a probe distance of 113 million km, can be viewed at the NASA.

NASA Associate Director of Scientific Affairs John Gransfeld reports that managed to take a picture of the ice cap at the North Pole of the celestial body. In other images recorded large moon of Pluto – Charon.

“As we approach the device to Pluto, we begin to notice the intriguing details like bright spot near the visible pole of this mysterious planet” – Daily results Mail words of John Gransfelda.

According to him, the picture may have captured ice polar cap. In other images could see the largest moon of Pluto – Charon, but the other four, smaller size, while “left-overs”.

“After nine years of traveling New Horizons amazing to watch as Pluto which seems to point, when we look at it from the earth, taking concrete shape right before our eyes – said the scientific director of the project, a member of the Southwest Research Institute Alan Stern. – The first detailed images of the planet show that it has a complex surface “.

Scientists hope that on 15 July 2015 when the New Horizons will pass at a distance of 12.5 thousand. km of Pluto, they will get a new unique information. After a rapprochement with Pluto probe goes beyond the orbit of Neptune – to other objects in the Kuiper belt.

“You can not even imagine what discoveries await us next summer” – said the employee of the University Applied Physics Laboratory Hal Weaver of Johns Hopkins. In this lab was built a unique device, take a trip 19 January 2006 and since then has overcome in the space of about 5 billion kilometers. Now he came to the finish line and must fly at a minimum distance of Pluto in July this year.

It should be noted that the mission of New Horizons, NASA which cost more than $ 600 million, began nine years ago – machine launched into space January 19, 2006.

Note Pluto was discovered by Clyde Tombaugh, American astronomer in 1930. He was considered the ninth planet of the solar system until 2006 after verification sizes has not been declared a dwarf. The diameter of Pluto – about 3 thousand. Km, while the diameter of the moon is about 3.5 thousand. Km.

New Horizons probe photographed the polar cap Pluto – BBC News

New pictures transmitted by the device “New Horizons”, the astronomers showed bright spot near one of the poles of Pluto. Scientists believe that this is a sign of the ice cap, but rather it will be able to find out just as you approach the probe to dwarf planet.

The pictures were taken in the period between 12-18 April 2015 at a distance of 113 million kilometers and demonstrated not only Pluto and its largest moon, Charon.

However, the main attention was paid to scientists Pluto. Its surface is a patchwork of light and dark areas of a diameter of several hundred kilometers. One of the polar regions, regardless of the rotation of the dwarf planet is very bright. Astronomers suggest that is responsible for this ice cap, actively reflect sunlight. However, while this is only a very shaky assumption.

“rarely seen in the pictures of the planets of the solar system such a low resolution so obvious surface features. We do not know whether to answer for the bright and dark areas of geological, topographical features, or composition of the surface, “- said Alan Stern (Alan Stern), a leading researcher of the New Horizons mission, the Southwest Research Institute in Boulder (Southwest Research Institute in Boulder).

Let’s add, that earlier the same quilt demonstrated pictures of the telescope “Hubble”, but even this cosmic monster is unable to provide a clear picture.

Now the probe New Horizons is located at a distance of 90 million kilometers and continues to approach the dwarf planet rendezvous is scheduled for July 2015.

In the future, new research and measurements will enable to find out what exactly is the polar cap Pluto. While it is supposed that the surface comprises a dwarf planet frozen nitrogen, carbon monoxide and methane. Some compounds may evaporate and form a thin atmosphere.

The site of the journal Nature adds that the New Horizons mission specialists upload photos to on-board cameras 48 hours after their delivery to Earth. At the same time, scientists working in the mission “Rosetta” comet and study Churyumov-Gerasimenko, provide very limited access to the captured photos. Yesterday, April 29, 2015, the network has photos of one of the chambers of the probe, dated August-sentyabrёm 2014.

The analysis found near the “progress” version of the wreckage pointed to the explosion – NEWSru.com

Experts continue to investigate the cause of lost Russian cargo spacecraft “Progress”, launched into space on April 28. According to them, until confirmed two assumptions – the failure occurred at the stage of separating the vehicle from the third stage of the carrier rocket “Soyuz”, while failure could cause an explosion, according to “Interfax” , citing a source in the space industry close to the commission for investigation of emergency in orbit.

The fact that the failure occurred at the stage of the third stage, reported shortly after the launch. Experts PCO reported that the two-stage rocket “Soyuz” worked normally, but on the stage of the third stage failed, causing the rapid rotation of the spacecraft “Progress”. Later, a Version blast . It was also reported that found the US Air Force Space Center around the wreckage of the truck can be a result of the impact of the ship and the third stage of the rocket in the moment of separation. This was announced on the eve RIA “Novosti” of the Russian Academy of Cosmonautics Tsiolkovsky, chief editor of “Space News” Igor Marinin.

Experts analyzed the orbit of the Russian Space Agency fragments found near the freighter. According to one of the pre-release “cloud” fragments could be formed as a result of “explosive effect”, a source said Thursday the agency “Interfax”.

According to him, experts are now busy identifying the wreckage, as well as an analysis of their orbits. Most likely, the explosion occurred at the time of separation of the ship from the third stage, the source added.

In the study of the parameters of the orbit 15 of the largest fragments of experts drew attention to the large height variation. According to American data, they are at altitudes from 170 km to 370 km and an apogee of 130 to 180 km – at perigee.

“Given this, and the fact that the ship” Progress “was found about 30-40 kilometers above the calculated orbit and thus strongly rotated around its axis, we can confidently say that the separation spacecraft from the third stage of the launch vehicle was something like an explosion, “- a spokesman said.

According to him, the information available is not enough to say for sure that it exploded. “With the accumulation of the necessary information will be carried out mathematical modeling of all possible processes occurring in orbit. It will then select the most likely version” – the spokesman said.

“Progress” was lost due to a failure in the third stage of the rocket “Soyuz”

Source Tass in Roskosmos earlier reported that the cargo ship from a third stage carrier takes nine minutes after launch. Later, experts reported that over 1.5 seconds before the truck separating from the rocket stopped coming to his telemetry. The first deputy head of the Russian Federal Space Agency Alexander Ivanov then suggested that the cause of the accident could be an emergency situation at the time of the separation of the rocket and spacecraft, wrote “Rossiyskaya Gazeta” .

Because of the failure of the ship was in orbit above the settlement. Furthermore, there was a strong its rotation around its axis – a speed of about 90 degrees per second. From the Earth repeatedly sends a command to switch the main engine of “progress”, but it does not load.

Later, the US military discovered in orbit near the “progress” and the third-stage rocket “Soyuz” several tens of debris, which presumably could be fragments of the ship or cargo rockets. Academician of the Russian Academy of Cosmonautics Tsiolkovsky, Yuri Karash told “Interfax” that if the ship started to fly off the wreckage, he likely suffered serious effects from either inside or outside. In the first case, this means that the vehicle exploded. “Most likely, it just exploded,” – said Karash.

The fragments found in space found elements of the “Union”

29 April Roscosmos announced preliminary results of the analysis
 the situation with the failed launch of “progress”. According to them, “in
 additional testing of systems and components ship 29
 April 2015 established failures of individual components and assemblies
 cargo vehicle and found no
 tightness highways propulsion unit “. It
 recorded outflow of gas from the pipelines of the ship.

According to the Russian Federal Space Agency, the ship is located at an altitude of 270 km
 apogee and perigee of 190 km. The ship and the third stage of the rocket were in
 orbit launch approximately 30 kilometers apart.

Commenting on information about detected near the “progress” 44
 fragments, the first deputy head of the Russian Federal Space Agency Alexander Ivanov
 did not rule out that some of these fragments – “are elements of design,
 which cleanly away from the third stage at the time of separation from the ship
 - Pirotolkateli, body pushers, springs “.

He said that” at the moment of such statistics we have, but
 when we get updated information, we will verify. “” As long as say
 clearly, it is the wreckage of something, you can not “- said Ivanov.
 At a briefing at the Russian Space Agency announced that the Commission
 investigate the causes of the emergency start “progress” should present
 its conclusions of 13 May, when the state commission should be to make a decision
 on the possibility of launching manned spacecraft with the help of
 rocket “Soyuz-FG”. The launch is scheduled for May 26 from Baikonur.

The ship “Progress M-27M” commit uncontrollable descent from orbit. According to specialists Roscosmos, the ship must enter the dense layers
 the atmosphere and burn up in the period from 5 to 7 May. Forecast of a
 point on the globe that happens, it will be only two days before
 fall. However, according to experts, the wreckage of the space of the truck before it reached the Earth and burn up in the dense layers of the atmosphere.

The probe New Horizons studied polar cap on Pluto – Sight

The spacecraft New Horizons «reviewed» to the dwarf planet Pluto is a bright spot, which is believed by scientists from NASA, could indicate the presence of her snow-covered from molecular nitrogen polar pole.

«As we approach to Pluto, we begin to notice the intriguing details, including light in the visible region of the pole we dwarf planet, we begin a great journey into the scientific understanding of this mysterious celestial body,” – said NASA spokesman John Gransfild, RIA ” News ».

Pictures taken mounted on the probe camera LORRI (Long-Range Reconnaissance Imager) from 12 to 19 April, more visible light than the rest of the surface, area near the pole of Pluto. The equipment of the probe from a distance of about a hundred million kilometers recorded a full rotation around the axis of Pluto, which he performs in 6.4 Earth days. In addition to the images of Pluto got its largest moon Charon.

Scientists suggest that they had seen a cap of Pluto can be explained by the fact that the dwarf planet pole snow covers the kind of zamershego molecular nitrogen.

In NASA noted that to confirm or refute this hypothesis will be possible in July when New Horizons to Pluto closer to a close distance. The unit will take place at a distance of 12.5 thousand. Km of plutonium in 5 billion kilometers from Earth on July 14. As we approach LORRI will continue to shoot the dwarf, the beginning of the next photo session is scheduled for May 8.

At the same time, NASA scientists now obvious that the New Horizons because they can better understand the structure of Pluto’s surface.

«These extraordinary images are the first in which we can see the nuances of the surface of Pluto, and we can already see that it is highly complex,” – said mission principal investigator Alan Stern, New Horizons.

Let’s remind, New Horizons was It launched in January 2006. In January this year, the machine began its journey to Pluto.

Experts made version of the explosion in the breeding of “progress” – RBC

When fading cargo spacecraft “Progress M-27M” into orbit could cause an explosion, told Interfax a source in the space industry, close to the commission of inquiry. According to him, this is indirect evidence analysis of the orbits of debris found near the ship.

«US and Russian space monitoring tools found near the” progress “several dozens of obscure fragments. Now experts are busy with their identification and analysis of their orbits. According to one of the pre-release “cloud” fragments could be formed as a result of the explosive effect, “- he said, adding that, most likely, the explosion occurred at the time of the separation of spacecraft from the third stage.

According to the US space center in orbit near the ship, and the third stage carrier 44 fixed debris. Experts drew attention to the large scatter fragments of heights – from 170 km to 370 km at apogee, from 130 to 180 km at perigee.

According to the source, given this fact, and the fact that the ship “Progress” was found about 30-40 km above the calculated orbit and thus strongly rotated around its axis, “it is safe to say that the separation of spacecraft from the third stage of the launch vehicle was something like an explosion.” He added that the data available is not enough to say for sure that it exploded. As they accumulate will be conducted mathematical modeling.

Start carrier rocket “Soyuz-2.1a” the ship “Progress” from the Baikonur Cosmodrome on April 28 at 10:09 MSK. The docking with the ISS has been scheduled for 16:07 MSK. However, after the separation of the third stage of the rocket from the unit ceased to act telemetry. After unsuccessful attempts to regain control of the ship in the MCC refused to take further action. “Progress” has started an uncontrolled descent from orbit.

According to the preliminary analysis of the Russian Space Agency, during additional testing of systems and components of the ship have been installed failures of individual components and assemblies cargo vehicle. Furthermore, the lack of tightness lines revealed propulsion unit. It was recorded outflow of gas from the pipelines of the ship.

Managers of space industry will not be punished for the accident “Progress” – Vedomosti

Roscosmos admitted the loss of the cargo ship “Progress M-27M” launched on Tuesday. “One thing is clear – an emergency situation with the” progress “has occurred at the time of separation [third stage] rocket” Soyuz-2.1a “and the ship,” – he said at a special briefing on Wednesday, the first deputy head of the Federal Space Agency Anatoly Ivanov. After this emergency situation the ship was damaged, making it impossible to dock with the International Space Station (ISS). Over establish the exact causes of the accident will be working committee, the conclusion of which must be received by 13 May, when will decide on the start of the ISS on May 26 manned spacecraft “Soyuz TMA” (it starts with another modification of the “Union” – rocket “Soyuz-UV” ).

The cost of producing ships and missiles with the launch, according to the head of Roskosmos Igor Komarov, was 2.589 million rubles., Including the rocket itself with a fairing and ship – 1.986 billion rubles., The last the amount he was insured. Previous (and the first in the history of this type of ships) the loss of the space truck occurred because of rocket failure in August 2011, and the launch of “Progress M-12M” was not insured, which put the blame then leadership of the Russian Space Agency.

Igor Komarov The head of the Russian Space Agency

A further flight of the ship and its docking with the ISS is not possible. & Lt; … & gt; Without removing the fault and no one else shifting should determine the true cause.

According to the Russian Federal Space Agency, decayed and combustion in an atmosphere of pre-emergency ship is expected on May 5-7. In total this year planned to launch to the ISS four “progress” (one launched in March), but the accident left two launch will likely postponed to a later date, said Ivanov. According to him, a threat to the crew of the ISS in connection with the undelivered cargo him missing.

According to the person in the government, this failure will not affect the position of the current leadership of the space industry and its supervisors in the government. Systemic problems have long been observed and Astronautics everyone understands that they are not quickly solved, the new team led by the former president of “AvtoVAZ” Komarov set last year just for this, the official recalled. According to him, the head of the Russian Space Agency, Anatoly Perminov, was filmed in 2011, including a series of failed launches (including previous bad start “progress”), and his successor Vladimir Popovkin and Oleg Ostapenko resigned is due to a failure starts, which happened and during guidance. Dismiss and business leaders for the most egregious of the accident due to negligence at work, but now it will not and that, although it is necessary to await the outcome of the investigation, said the source “Vedomosti”. The new team at Roscosmos came recently to reform the industry, the purpose of which is to avoid such unpleasant stories, so some high-profile resignation today illogical agree corresponding member of the Academy of Astronautics Andrew, son of John.

“Progress” with the Banner of Victory falls to Earth – BFM.Ru

«Progress” made three turns around the Earth, and during that time it was not possible to fully re-establish contact. The ship is still not transmitting telemetry information

According to Tass, citing a source in the Mission Control Center (MCC), the deviation of the space truck “Progress M-27M” from the nominal orbit is not as critical, but it is without correction It may be lost. Its orbit at a low point of about 120-130 km. Thus, the ship “catchy” atmosphere.

According to the data of the Joint Command North American Aerospace Defense (NORAD), «Progress” was launched into orbit at a perigee of 123 kilometers and an apogee of 306 kilometers. It’s called short-lived in the absence of correct ship can See also: The flight without progress. With delivery of the Victory Banner to the ISS had problems to fall, writes dni.ru.

«Progress” made three turns around the Earth, and during that time it was not possible to fully re-establish contact. Ship still not transmit telemetry information. Earlier it was reported that the telemetry received, but this information is not confirmed. The Mission Control Center reported that on April 28 there were only two attempts to restore full ties. “On the fifth turn of the ship will come from the Russian zone of communication and it will be tomorrow,” – said a spokesman for the Mission Control Center.

Meanwhile, it became known that docked launched space truck “Progress M-27M” with ISS moved from April 30 for an indefinite period. “Currently the ship very quickly and uncontrollably rotate around its axis, one revolution – just a few seconds. Teams from the Mission Control Center aboard the ship are not, telemetry is also intermittent, “- says the representative of the MCC.

The cause of abnormality in the launching of a space truck” Progress “is likely to become not perform as one of the steps carrier rocket “Soyuz”. As the experts assure, the ship lost contact because the rocket led him into an unplanned orbit. This situation is not due to the fact that he had not revealed two of the five docking antenna systems “course».

Roscosmos flood “Progress-M27M” guilty of a state of emergency will special commission – RIA Novosti

MOSCOW, April 29 – RIA Novosti. Federal Space Agency decided to reduce the orbit and flood the space cargo ship “Progress-M27M” as a continuation of the flight is not possible, told reporters the head of the space agency, Igor Komarov .

The causes abnormal excretion of a truck in orbit will be to find out a special commission of Roscosmos. Previously it believed that the incident occurred due to a problem in the separation of the carrier rocket and spacecraft.

abnormal situation occurred on Tuesday morning: a truck “Progress-M27M” after the launch of a “Baikonur” for unclear reasons, was launched on unplanned orbit and can not dock with the ISS. Now “Progress M-27M” continues its flight mode uncontrolled “spin”.

Total to date there are three separate issues: the so-called “spin” of the ship at a high speed, non-disclosure of multiple antennas automatic docking system ” Course “and the inability to receive telemetry from the ship and give him commands.

to do everything they could

Experts tried to revive distress in orbit” Progress “more than a day, but a full-fledged relationship with him and failed to establish.

“The transport ship in the near future can be considered debris, threatening security. Docking with the ISS is not. The engines of the fact that uncontrolled rotation stop fails, run a risk. In the uncontrolled twisting the ship flies certainly not less than a week, and then enter the atmosphere and burn up. Where – is unclear, “- told RIA Novosti source in the space industry.

On the first day trying to run the truck engines are not undertaken, and on Wednesday during the next passage of “progress” of the Russian zone of radio visibility of such an attempt was not successful.

In the middle of the day, it was decided to stop trying to contact truck. By lunchtime, it was reported that “Progress” started a gradual uncontrolled descent from orbit.

“Since the start the engine and take corrective maneuver fails, the space truck gradually loses orbit. The rate of reduction will vary depending on the state of the atmosphere and the solar wind, but overall the ship only for those hours lost tens of meters high, “- said RIA Novosti source in the space industry.

However, the First Deputy General Designer of RSC” Energia “, the head of the Russian mission segment of the ISS, Vladimir Solovyov on Wednesday night announced that the DRM will be up to the last attempt to establish contact with the space truck.

Flood – can not save

In the late afternoon the Federal Space Agency decided to gather journalists and explain what is happening with “progress.” Previously, such situations these trucks did not happen, so the incident is given a lot of attention, in part because it is the first state of emergency in the aerospace industry after the Roskosmos led by Igor Komarov. The situation of the monitor and the Deputy Prime Minister Dmitry Rogozin, and the Kremlin.

“In the course of further testing units ship today revealed no leaks in the line of the propulsion system. In this regard, the continuation of the flight of the transport ship, its safe docking with ISS is not possible “, – told reporters Komarov.

He said that an emergency situation is likely to have originated in the separation of the spacecraft and the launch vehicle. The same opinion was expressed earlier in an interview with RIA Novosti and academician of the Russian Space Academy named after Tsiolkovsky Igor Marinin.

Many concerns have caused US identified NORAD system orbit “progress” items of space debris. Experts said the RIA Novosti news agency, it may contain, dumps the separation of the third stage of the rocket from the truck. Roscosmos agree with this version.

The further fate of the space truck resolved – it will be flooded and will burn in the atmosphere before reaching it.

“With regard to the calculation of incidence and unburned fragments on Which countries – we mean it in a few days. Now, roughly, the ship “Progress” will complete its mission on May 5-7, “- said the first deputy designer general of RSC” Energia “, the head of the flight of the Russian segment of the ISS, Vladimir Solovyov.

Who is to blame?

In order to analyze the incident with space truck “Progress-M27M” Roskosmos created a subgroup of the state commission. It will have to prepare all the necessary proposals, which must be considered in the preparation of the next start.

The results and conclusions of the Commission shall provide until May 26, this is the date scheduled for the next manned launch of the program, whose mission – to deliver to the International Space Station Expedition new members.

The findings, who is to blame for state of emergency with “Progress”, will be made after all the circumstances, Komarov said.

“to understand, I think, the reason will be installed and we will inform about it. Although there are partners who work for the corporation (RSC “Energia”). Without removing the guilt and not shifting it on anyone, should determine the true causes, and then to conclusions, “- said Komarov at press conference in the Russian Space Agency.

Space Plan work will not suffer

Postpone scheduled for the second half of May manned space flight is not planned, including because this mission is to perform another modification of missiles “Union”, namely the “Soyuz-FG”, rather than the new “Soyuz-2.1a,” Roskosmos said.

But the plan launches new cargo ships for the current year will be adjusted.

“We will launch two adjustments” progress “this year. One will be put to the third quarter of this year, the second – on the fourth, “- said Wednesday the deputy head of the Russian Federal Space Agency Alexander Ivanov.

After the analysis of the existing provisions on board the ISS, it became clear that the crew is fully provided with all necessary to continue work before the arrival of the next space truck.

The head of mission of the Russian segment of the ISS, Vladimir Solovyov also assured that the clash between the space station and the truck is not possible, the crew is not in danger.

The next launch rocket “Soyuz-2.1a” is scheduled for May 15 from the cosmodrome “Plesetsk” in the interests of the Russian Defense Ministry. It will carry out calculations troops Aerospace Defense. To decide whether to be or not to launch, at the disposal of the War Department two days before launch date will give all materials to investigate abnormal situation with the launch of “Progress” in the “Soyuz-2.1a”.

The incident with the “progress” should not cast shadows on the reliability of Russian rocket “Soyuz”, convinced the deputy head of the Russian Space Agency Ivanov . According to him, these statistics successful launches no one family of launch vehicles in the world.

“What happened is some emergency situation that we are now is we can not explain, in no way can not deliver cross on the operation of launch vehicles family “Union”, “- said Ivanov.

Mission Control gave up trying to take control of cargo spacecraft “Progress M-27M”, Interfax reported with reference to the interlocutor in the space industry.

He said that the last attempt to bring the situation under control in It was not successful, and it was decided not to take more of them. “The last attempt to bring the situation under control failed. Resolved longer attempt not to repeat “- a spokesman said.

According to him, the ship has already begun spontaneously fall out of orbit, anticipated the fall of the debris of the earth – from 7 to 11 May.

Meanwhile, a source in the TASS space industry claims that the DRM experts today after a break will take at least another three attempts to take over the management control of the ship. “Specialists PCO remain in the field and will, to the extent possible, to do something. At least three more sessions should be, “- said the source.

He said that space makes the truck a day around the Earth turns 15-16, only six of them fall into the zone of the Russian ground communications. With 3:50 MSK on April 29 experts made six attempts to take control of an emergency, “Progress”, all of them were unsuccessful.

Later, the agency, citing a source reported that experts have recognized the situation hopeless. “Experts have recognized that the situation with” progress “unpromising. Controlled keep the ship from orbit will not work “- said Tass.

The launch vehicle” Soyuz-2.1a “the truck” Progress M-27M “launched from the Baikonur Cosmodrome in the morning on April 28. Six hours after the start of a cargo ship was due to arrive to the International Space Station. But there was an emergency situation – the ship has exceeded a predetermined height and did not leave the calculated orbit. “Progress” began to rotate around its axis, and it ceased to flow telemetry information. The MCC is believed that the failure occurred at the stage of the third stage.

Earlier on Wednesday, a source in the MCC told Interfax that if the experts of the center will not be able to take the ship under control, it is possible to mix his early orbit. RIA Novosti source in the space industry most likely scenario for a gradual reduction in calls of “progress” orbit flight, after which the ship will burn up in the atmosphere.

Experts Mission Control Center (MCC) will try to take control of the cargo ship “Progress” for further information safe from orbit , said a source in the space industry.

«The question of the possibility of joining” truck “and ISS is not worth it. The main thing – to provide his more or less controlled and safe de-orbiting. If in the next few hours the problem is not resolved, the ship will begin a natural decayed, due to the deceleration in the upper atmosphere. It is estimated that unmanaged decayed ship can happen in early May, “- said to” Interfax “spokesman, noting that the specialists the task to restore the orientation of the spacecraft and to stop its rotation around its axis.

Earlier “Kommersant” reported that docked launched April 28 space truck “Progress M-27M” with the ISS on Thursday postponed indefinitely.

Rocket ” Union “with the spacecraft” Progress M-27M “launched from Baikonur at 10:09 Moscow time. After undocking from the rocket ship in the MCC said that the land does not enter the telemetry. Source Agency in the space industry said that the “progress” is not revealed two antennas docking system “Kurs”, the ship did not come into the proper orbit due to a malfunction in one of the stages of the carrier rocket “Soyuz-2.1a».

Two attempts to establish a stable relationship with the cargo ship “Progress M-27M”, the launch of which took place on April 28 did not lead to success, according to Interfax citing a source in the Mission Control Center.

«On board the” progress “has been transferred several teams, aimed at stabilizing the situation and reduce its rotation around its own axis. Now comes the analysis of the data. According to preliminary information, the problem has not been solved “, – told the agency.

The cargo vehicle” Progress M-27M “launched on Tuesday at 10:09 am from the Baikonur cosmodrome, the unit brought to orbit launch vehicle” Soyuz -2.1a. ” According to the plan, six hours after the start of the cargo ship should dock to the International Space Station.

However, the ship did not come into the proper orbit. As previously wrote RBC, it has exceeded a predetermined height of 30 kilometers. In addition, the ship began to spin and he stopped coming telemetry information.

Sources told the agency at the time that the two-stage rocket “Soyuz” worked normally, but the failure is likely to have occurred at the stage of the third stage.

 “As long as the ship is stabilized around its axis, no maneuvers are impossible with him, including rendezvous and docking with the ISS,” – the source added.

As one of the possible solutions include experts called teleoperator control mode. By the evening of April 28 experts have stopped attempts to contact the ship and planned two attempts due to the early morning April 29.

Truck “Progress” was supposed to deliver to the ISS crew required to operate the station fuel, oxygen, equipment for scientific experiments, parcels for cosmonauts and astronauts and gifts for members of the crew for the upcoming holidays, as well as food. However, NASA said that the non-standard access to the orbit of the cargo ship “Progress” will not affect the operation of the plant. The space agency assured that the lives of astronauts, who are now on board the station, there is no threat, they continue to work as usual, and the station has the necessary reserves.
