NASA discovers leak aboard the space station

Astronauts have been working to locate and seal a small leak that has opened up aboard the orbiting outpost.
According to reports, flight controllers on Earth first noticed that something was up when they detected a slight drop in cabin pressure on Wednesday evening at around 7 p.m. EDT.

Upon waking, the crew quickly got to work hunting down the location of the leak.

The culprit, it turned out, was the Soyuz MS-09 spacecraft currently docked at the station.
It appeared as though a small meteorite had punched a hole through its hull.

"The leak has been isolated to a hole about two millimeters in diameter in the orbital compartment, or upper section, of the Soyuz MS-09 spacecraft," NASA said in a statement. "The rate of the leak was slowed this morning through the temporary application of Kapton tape at the leak site."

"Flight controllers are working with the crew to develop a more comprehensive long-term repair."

Fortunately the leak doesn't appear to be serious and does not pose a risk to the crew.

How would a micro-meteoroid cause a fire?

Only when there is six crew. When three crew return home there is just one Soyuz until the next compliment arrives, then there are two again. Each Soyuz can only hold 3 crew. When the ISS is fully manned it would need both Soyuz to evacuate.   Yep.   No redundancy at all, whether there is one or two (or in a few very rare cases three) present. It costs several tens of millions of dollars tomalunch each astronaut/cosmonaut. It is simply too expensive to have extra Soyuz seats available.   Are you going to present evidence for this or are you just guessing? Of course you won't present evidence, ... [More]

Now, you'd have thought some bright bugga, would have the foresight to pack a patch or two in the event of a micrometeor strike!? I mean, it's not as if things are whizzing about up there at great speed or anything!

They did, the hole is patched.

Got that Waspie_dwarf, they described it as a bit of tape that isn't doing the job of a proper patch and engineers are working on a solution. A bit of prethought would have a properly, lab tested, fully function patch in the hold for just such occasion.

Friction.
Comment icon #12 Posted by Waspie_Dwarf 4 years ago
What, you mean in the same way that people that have been shot always burst into flames? Oh, hang on a minute, they don't. There is very little friction. On impact the micro-meteoroid will pretty much vaporise. Since it is tiny the amount of energy that it releases will also be tiny.

To "vaporise" requires total conversion of kinetic energy to heat. In this case aluminium has a vaporisation temperature of 2327C and releases 10530kJ/kg energy. It is the environmental characteristics that will determine whether high temperature oxidisation takes place. Friction in such a scenario is of course very high breaching the mechanical integrity of the molecular bonds that leads to vaporisation.

Well don't need to be rude  ?  I'm not always here on the forum and it's not a personal attack against you. 1) Soyuz are quite rugged, Resisting reentry need a rugged aircraft... They have done ballistic reentry with the servie module stuck on with faulty explosive bolt. So it's rugged. Can the ISS do that ? nope but  ISS and Soyuz are two totally different type of machinery, but one is expandable, the other not. ISS need to be build for the long term. The Soyuz is build to go back to earth while keeping is load in one piece. Expandable mean they can trow it away and the Russian will bring ano... [More]
