The failure of the sensor resulted in the failure of the launch of Soyuz, says Roscosmos • The Register

A crew crisis at the International Space Station could be avoided, with Russia's Roscosmos saying the Soyuz launch incident this month was due to a sensor failure. sensor detecting the separation of the first and second stages of the thruster.

The crew capsule works as expected: it separates and performs a ballistic return on Earth with American astronauts Tyler "Nick" Hague and Russian Alexey Ovchinin shaken and restless, but unharmed.

Roscosmos immediately began investigating the failure of the launch, under the pressure of time, because the current crew of the ISS had a deadline of January to return to Earth . When the launch of Soyuz failed earlier this month, the uncertainty surrounding the ISS crew launch schedule has hinted that the space station should be abandoned, at least for the moment.

Speaking in front of the Russian Academy of Sciences, Mr. Krikalev said that the sensor in question "should signal the removal of the first floor of the second rocket." From the failure of the sensor, a side block of the first stage of the rocket was poorly separated, which had an impact on the second-stage fuel tank, which then exploded.

The explosion was at the origin of the briefly terrifying moment of the live launch video when the crew were briefly shaken, before the return of the capsule to Kazakhstan
