WATCH: How Russia’s rocket launch failed

On October 11 this year, a Russian Soyuz rocket experienced malfunction after lifting off, forcing a NASA astronaut and a Russian cosmonaut to make an emergency landing back to earth.

It was supposed to be a routine trip to the International Space Station, however, while ascending at speeds of roughly 5400 km/h, one of the four boosters of the Soyuz rocket failed to dispatch properly, forcing operators to abort the mission.

The Soyuz had ascended roughly 50 km at the time of the incident.

Both the pilots, furthermore, safely made it back.

You can watch how the accident occurred at the 1:24 mark.

Earlier this month, Russian investigators explained that a faulty sensor was the reason behind the accident, adding that the component was likely damaged during assembly.

Two other Soyuz rockets were also grounded for further checks.
