Last week astronauts on board the International Space Station (ISS) awoke to a worrying message from flight control. “Warning Pressure Leak”
Hidden somewhere on board the ISS was a tiny pressure leak that was slowly allowing air to seep out of the spacecraft and into the abyss.
The six astronauts on board were not in any imminent danger, although locating the leak was their top priority for the day. The US crew hunkered down in the Russian segment and sealed off all the compartments one by one.
A two millimetre hole was at last discovered in the Russian segment itself. And while that hole may not seem very big, if nothing had been done to fix it, it would have deprived the ISS of air in just 18 days.
