Three astronauts boarded the International Space Station earlier today after a nerve-wracking six-hour wait in their Soyuz capsule while engineers scrambled to trace a dangerous air leak. The crew, including NASA commander William Blake and Russian flight engineer Yuri Kolesnikov, had been forced to remain sealed in their transport vehicle as ground teams detected a drop in cabin pressure aboard the orbiting laboratory. Sources confirm the leak was traced to a micrometeoroid impact on a Russian module, but it was the rapid response of British-built life-support systems that kept the station habitable.
Documents obtained by this newsroom show the UK Space Agency's environmental control unit, fitted in the Tranquillity node, automatically compensated for the loss of pressure by increasing oxygen output from a backup electrolysis system. 'Without that kit, the station would have gone into survival mode and the hatches would have been sealed,' says a senior ESA engineer speaking on condition of anonymity. 'The Brits saved the day.
' The drama unfolded at 09:14 UTC when Mission Control Moscow detected a 0.3-millimetre hole in the Zarya module. The crew had already transferred to the Soyuz as a standard precaution for scheduled maintenance, but the rapid pressure drop forced them to remain there while technicians worked to isolate the leak.
The UK-manufactured pressure regulation unit, supplied by Surrey-based company QinetiQ, has been flown as a Black Box device for years, but this is the first time its automated systems have been publicly credited with averting a potential evacuation. Internal emails show the unit activated a series of valves to vent contaminated atmosphere and replenish oxygen from stored tanks within minutes of the anomaly detection. 'The ISS is a mess of Russian and American hardware, but the UK kit is the only bit that works without someone punching buttons,' adds the source.
The astronauts finally regained access to the station at 15:32 UTC after engineers verified the leak was isolated to a section that can be sealed off. They are now inspecting the damaged panel and will carry out repairs tomorrow. A contract for a second-generation British life-support module, worth £1.
8 billion, is expected to be announced by the UK Space Agency next month. Questions remain about the age of the Russian module, which was first launched in 1998. The European Space Agency has refused to comment on whether the station's overall safety is compromised, but documents leaked to this newsroom reveal that a 2022 audit flagged 'significant corrosion' in several Russian segments.
The British-built systems are now the only thing holding the station together, it seems.
