NASA Emergency Ordered SpaceX Dragon to Evacuate Astronauts after Russia ISS Module Leak Worse...
Leaks on the ISS are nothing new. But what happened on June 5th, 2026 was different — this was the first time in 27 years of continuous operation that the situation was serious enough to trigger an immediate evacuation order. Five astronauts had to drop everything and take shelter inside a SpaceX Crew Dragon, suits on, hatches sealed, with one very clear contingency plan: if things got worse, they were leaving. Fast. Straight back to Earth.
Fortunately, it didn't come to that. But the fact that it almost did tells you everything about how badly this problem has deteriorated. So what actually happened up there? And why is this scarier than most people realize? Let’s find out.

Imagine you're floating 400 kilometers above the Earth's surface, inside the most expensive engineering achievement in human history — and every breath you and your fellow astronauts take depends on one thing: oxygen. Now imagine that somewhere, invisible and silent, a leak is steadily pulling that oxygen out into the frozen vacuum of space.
This isn't a movie. This was a real emergency aboard the International Space Station on Friday, June 5th, 2026.
To understand why that day felt so desperate, you have to go back seven years.
In 2019, Roscosmos engineers first detected air leaking from a section called the PrK — a narrow transfer compartment at the rear of Russia's Zvezda module, connecting the aft docking port to the rest of the station. This is where Russian Progress cargo ships regularly come and go, delivering fuel and supplies. And this is where microscopic cracks had been quietly eating away at the station's structural integrity.
Four causes were converging at once.

First: mechanical stress from Progress resupply vehicles. The Russian Probe-and-Drogue docking system is not the smooth, gentle affair you see with NASA's docking system on the Dragon capsule. Every docking is a controlled collision — hard mechanical impact, compressive force, cyclic vibration as the hooks engage and the seals lock. Over years of repeated dock-and-undock cycles, that cumulative stress leads to metal fatigue, and fatigue leads to cracks — particularly near the welds in the PrK region.
Second: thermal cycling. The ISS completes sixteen orbits every single day, which means sixteen sunrises and sixteen sunsets — and sixteen brutal swings between scorching heat and absolute cold. Imagine stepping out of a room set to 61°F into 104°F outdoor heat, over and over again.
