Russian Soyuz Rocket Failure Caused By Damaged Sensor, Reveals Probe

Russian official says Soyuz rocket failure caused by an errant sensor

About 84 seconds into the video, you can see one of the side boosters stick to the rocket, sending it careening back to the ground because it was too heavy.

The Soyuz MS-10 spacecraft carrying the crew of astronaut Nick Hague and cosmonaut Alexey Ovchinin blasts off to the International Space Station (ISS) from the launchpad at the Baikonur Cosmodrome, Kazakhstan October 11, 2018.

Skorobogatov said officials are now taking steps, including putting all assembly staff through competence tests and additional training, to make sure such malfunctions don't happen again.

In Roskosmos claim that the cause of the accident during the launch of the carrier rocket "Soyuz-FG" was abnormal operation of the sensor indicating the separation of the first and second stages of the carrier.

The Russian-American crew of two had to withstand a ballistic descent back to Kazakhstan on October 11, but both emerged from their landing craft safe and sound.

Nearly three weeks ago, a Soyuz rocket carrying a NASA astronaut and a Russian cosmonaut failed in mid-flight, 31 miles above Earth's surface.

The last time Russian Federation saw an aborted manned launch was in 1983, when two Soviet cosmonauts jettisoned and landed safely after a launch pad explosion.

Igor Skorobogatov, who headed the inquiry, said on Thursday that the issue was linked to the "deformation" of a sensor part.

During the aborted launch, Russian cosmonaut Aleksey Ovchinin and USA astronaut Nick Hague made an emergency landing and escaped unharmed.

He explained that "it could have happened only during the ... rocket on-site assembling at the Baikonur Cosmodrome", ruling out any design errors.

The rocket producer will also take apart two other rockets which have been recently assembled and are due to launch in the coming weeks and then reassemble them, Skorogobatov said.

Russian officials believe that the defective component was damaged during assembly.

Referencing findings of an official inquiry into the accident, Skorobogatov said two more Soyuz rockets might have the same defect.

"Every accident has a name and surname (of the guilty party)", he said.

The upcoming launch will loft cosmonaut Oleg Kononenko, NASA astronaut Anne McClain and the Canadian Space Agency's David Saint-Jacques.
