As per reports, astronauts in the US sector of ISS have been forced to stay overnight in the Russian sector due to a suspected toxic leak from the cooling system. The incident has reportedly occurred at 11:44 AM, GMT.
If Interfax reports are true, then this incident is caused by the discharge of Ammonia. The six crew members which comprised of three Russians, two Americans and one Italian are safe in the Russian section. The concentration of Ammonia in the Russian section is safe, and there is nothing to worry.
Maxim Matyushin, head of the Russian mission command centre said that the safety of the crew members has been assured by timely actions.
He added that further repairing action on the American segment should be developed by the American side.
On the other hand, Mission Control said that all the crew members are safe, and there is no need to evacuate ISS crew to docked Soyuz rescue vehicle.
As per them, repairing the damage caused by Ammonia leakage will demand an unscheduled space walk.
NASA has not confirmed this news of ammonia leakage. The Space Agency tweeted that the crew members are safe, and they have not confirmed the leakage of toxic substance.
They added that the assessment processes are continuing, and the crew is following safety procedures.
Six members who are carrying out two expeditions are staying in the ISS. US astronaut Commander Barry Wilmore and Russian cosmonauts engineers Aleksandr Samokutyaev and Elena Serova are the members in expedition 42.
US Commander Terry Virts, Italian Engineer Samantha Cristoforetti and Russian cosmonaut engineer Anton Shkaplerov forms the team of Expedition 42.
