The cause of the leak on the International Space Station is still being investigated by NASA and the Russian space agency.
There are currently seven crew members on the International Space Station, of which three had been scheduled to travel on the Soyuz spaceship which leaked last week. The video on NASA TV showed a leak from the spaceship, and later it was confirmed that the temperatures inside were going up.
The head of the agency, Yury Borisov, said in a press briefing that there were no fears about the well-being of the crew of the International Space Station.
The issue now is how astronauts on board the International Space Station will return to Earth, as it seems unlikely that they will use the Soyuz, which leaked its coolant. Another craft could be sent to the International Space Station to bring the astronauts home.
There is a chance that the launch of the Soyuz in March could be moved to February so that the three crew members can return to Earth. NASA says that Roscosmos is looking into this possibility, but hasn't made a decision.
Two agencies are looking into the cause of the leak. It had been thought that the leak might have been caused by an impact from a meteoroid, as the Earth recently experienced the annual Geminids meteor shower, when the planets passes through a field of debris left over from an asteroid. However, that seems not to have been the case as the leak on the Soyuz was not in the path of the meteoroids. NASA and other space agencies are still trying to figure out what caused the leak, which could have been a meteorite impact or something else.
There is a recommended video.
