Russian investigators discovered the cause of the hit The arrest of the launch of Soyuz on October 11 had triggered a spectacular emergency escape for the commander of the mission Russian and his co-pilot from NASA. Senior executives said Thursday that the incident was due to a "deformed" sensor in a system controlling the separation of a first-stage booster to strap the central core of the rocket.
Oleg Skorobogatov, who conducted the investigation into the accident, said the official. the sensor was damaged during final badembly at the Baikonur Cosmodrome in Kazakhstan, adding that the conclusion had been "proven and confirmed". He did not explain how the sensor had been bent, but only when badembling the rocket.
Soyuz rockets in preparation for upcoming flights will be inspected to ensure no similar problems.
A Soyuz rocket carrying a Russian Glonbad The launch of the navigation satellite is planned for the Plesetsk cosmodrome, north of Moscow, on November 3, and the launch of a Soyuz satellite equipped with MetOp C meteorological satellite, the 6th November (EST), Kourou, French Guiana.
Plan the launch of a supply ship at the Progress Space Station from Baikonur on November 16, a day after NASA and Northrup Grumman launch a Cygnus cargo capsule from the Mid-Atlantic Regional Spaceport , in Wallops Island, Virginia. The unmanned spacecraft Cygnus and Progress will both arrive at the station on November 18th.
Assuming these flights are going well, the Russians will continue their plans to launch the next Soyuz piloted pilot on December 3rd. Commander Oleg Kononenko, Canadian astronaut David Saint-Jacques and Astronaut Anne McClain flying to the International Space Station.

The current crew of the space station – Expedition Commander 57, Alexander Gerst, NASA astronaut Serena Auñón-Chancellor and cosmonaut Sergey Prokopyev – originally planned to return to Earth on 13 December. They now plan to come home a week later, December 20.
Before Prokopyev returns to Earth, Kononenko and he plan to participate in a spacewalk on December 11 to inspect the Soyuz MS-09 spacecraft that took the crew of Gerst in orbit June 6th. A small leak in the upper part of the spacecraft The housing module was detected and repaired in August, and Russian engineers want to know the extent of the damage.
They also want to know if the damage was caused by a deliberate act at a given point in probe processing, as suggested at one point by Dmitry Rogozin, head of the Russian space agency Roscosmos.
The launch abandonment of October 11 is the first such incident occurred since September 1983, when the Soyuz rocket, which is normally reliable, narrowly escaped. an explosion launching ramp. The only other attempt to launch Soyuz took place in April 1975, when two other cosmonauts were forced to make an emergency landing after a different type of separation problem.
Given the long history of the rocket and its systems, the badysis of telemetry and the examination of the Russian investigators were able to quickly identify what s? had pbaded during the last incident.
At a press conference in Moscow on Thursday, a spectacular launch video was released showing that the second central stage of Soyuz FG had quickly lost control after the rocket. Four first-stage boosters with belt crashed into the core.

With the departure of Gerst, Auñón-Chancellor and Prokopyev, the crew of Kononenko will have the station in its place until April, by which date another crew of Soyuz must take off.
The initial flight plan included Oleg Skripochka, NASA astronaut Christina Koch, and a United Arab Emirates guest astronaut to take off on April 5. He would have returned to Earth about 10 days later with Hague and Ovchinine. Thanks to this interruption of flight, it is not clear who will be going to the station next spring or how the flights will be sequenced.
In the short term, NASA hopes to continue launching a Northrup Grumman Cygnus cargo ship at the summit. An Antares reminder of Virginia mid-November, followed by the launch of a spacecraft SpaceX Dragon at the top of a Falcon 9 rocket in Cape Canaveral on December 4, the day after the departure of Kononenko's crew from Baikonur.
Two exits in the NASA space to install a second. set of batteries for the solar energy system of the space station are waiting. The Japanese freighter HTV that brought the batteries to the station in September will return to Earth on November 7th. He was originally supposed to take the old batteries out of the station, but they will have to be thrown away later.
