"The hole was made on the ground. The person responsible for the act of negligence has been identified," the source told the news agency.

Another source said a worker apparently accidentally drilled the hole, but instead of reporting it, simply sealed it. The sealant held for at least the two months the Soyuz spacecraft spent in orbit, before finally drying up and being pushed out of the hole by air pressure.

As Armand would say, "Glup!"

SABOTAGE!

Yep. Sabotage.

Quality control has been a common failing in Russian aerospace over the past few years. Remember the Proton Rocket crash in 2013?

(Here's the slow-mo to refresh the memory. YouTube link )

By July 9, it is transpired that investigators sifting through the wreckage of the doomed rocket had found critical angular velocity sensors, DUS, installed upside down. Each of those sensors had an arrow that was suppose to point toward the top of the vehicle, however multiple sensors on the failed rocket were pointing downward instead. As a result, the flight control system was receiving wrong information about the position of the rocket and tried to "correct" it, causing the vehicle to swing wildly and, ultimately, crash. The paper trail led to a young technician responsible for the wrong assembly of the hardware, but also raised serious issues of quality control at the Proton's manufacturing plant, at the rocket's testing facility and at the assembly building in Baikonur. It appeared that no visual control of the faulty installation had been conducted, while electrical checks could not detect the problem since all circuits had been working correctly.
[…]

The improper installation apparently required some considerable physical effort, which, somehow did not raise any alarm at GKNPTs Khrunichev's assembly plant in Moscow. Investigators immediately looked at already assembled Protons, including those in Baikonur, but did not find such an anomaly.

FYI, the Russian Space Agency has now retracted the claim of sabotage. They are going with a metorite as the source of the damage. Choose your own theory.

Winston Smith04 Sep 2018 5:12 a.m. PST

As of a September 4 byline, the Russian space agency is admitting the possibility of "sabotage", whether on Earth or in space.
Glup!

Sabotage is the willful causing of damage. I doubt it was that. I also doubt it was a meteorite strike (actually technically an asteroid strike). Here is a good picture of a small asteroid that punctured the Endeavor (third picture down):

I think the reported story is the most likely one. Some Bleeped text drilled a hole where he shouldn't have and then fixed it with epoxy, hiding the fact from his superiors. The hole looks drilled, even with the drill "skip" marks to the right.

I have always thought that stupidity explains far more than conspiracy.

For many decades, Alien operatives (some disguised as dogs in the early days) have sabotaged many Soviet and now Russian missions. :)

Winston, that is known as Hanlon's Razor.

They're now saying that a cosmonaut on the station may have done this to get home early; hole matches drill on the station…

So it was Wolowitz!

Bowman06 Sep 2018 3:28 a.m. PST

Then why repair it with metal reinforced epoxy and then hiding it?

Winston Smith06 Sep 2018 1:56 p.m. PST

When I was a supervisor in a factory making car mats, one of the sewers used to hide mats where he screwed up the binding. My angry meltdown is legendary…
All he had to do was ask me to cut a new one, and everything would have been ok. Instead he tried to cover up his work.
So, the current cover story has a ring if familiarity. grin
People screw things up. And then they try to cover it up.

I read earlier that the hike was patched with some sealant not designed for that. It dried out, and after 2 weeks in space, it was popped out by air pressure.
But I wondered why anyone would be using a drill there.

The space toilet need to be fixed to something right???

Winston Smith07 Sep 2018 9:35 a.m. PST

Yes. An outer bulkhead, preferably.
And you drill the hole for a Molly Bolt!

Winston Smith07 Sep 2018 9:46 a.m. PST

And this, Dear Reader, is why all those questions that get asked here about the proper glue for X to Y are legitimate. grin
