Astronauts’ spacewalk to remove explosive bolt

An explosive bolt was removed by the astronauts Sergei Volkov, who is the commander of the space station and another astronaut Oleg Kononenko. The bolt was removed after six-hour of spacewalk.

The operation was carried out to increase the safety level as they traveled back to earth on their Soyuz capsule. The bolts were said to be faulty and were catching fire on re-entry.
