# Where is the hole now? (ISS/Soyuz spacecraft hole)

Gizmodo's Report: ISS Hole Drilled From the Inside, Cosmonaut Says has made me realize I've lost track of the hole. It was in the part of a Soyuz spacecraft docked to the ISS wouldn't contain the crew during reentry, and recently the capsule segment of a Soyuz spacecraft has returned to Earth after the spacewalk happened to check out the outside of the hole.

But I don't know if the returning craft is the "holy craft" or a different one; the ISS was looking like a parking garage recently with so many spacecraft docked to it.

So is the hole still at the ISS, or has it been released to LEO, or re-entered the atmosphere? Where is the hole now?

below: screenshot from a recent Roscosmos tweet of cosmonaut Sergey Prokopyev (presumably) talking about the lead detection and repair and showing an ULD? (I can't speak Russian, but presumably this is correct.) Translating the text using Google:

"Friends, I decided to shoot a video to answer your numerous comments and dispel rumors. Everything is calm on the ISS! "

The damaged craft is a Soyuz-MS which is limited to 210 days1 docked at ISS. Because of this limitation it was the next to deorbit. Since the hole was in the orbital module and not the reëntry module there were no special concerns regarding the return to Earth. The craft, MS-09, returned safely to Earth on 20 December 2018, landing at 05:03 UTC.

Both the orbital module and service modules are released after the deorbit burn so both would have burned up in the atmosphere around the time of the descent module's reëntry and crashed about 830km short of the crew's landing site. Based on the ISS orbital track and reëntry time, it seems the hole (or what's left of it) is currently in one of the 'stans (probably somewhere in south-west Kazakhstan)2.

1 This limitation is due to the use of Hydrogen Peroxide in the reëntry module's attitude control thrusters. This fuel decomposes over time (into water and oxygen). If the fuel fully decomposes then return to Earth is still possible but only via ballistic descent. This answer and this one go into more detail. (thanks to uhoh for the first link).

2 Reëntry was from the south-west heading into central Kazakhstan.

Based on the ISS track from this site, the path of MS-09 was about 250 km to the north-west with the track crossing the center of (what's left of) the Aral Sea. I do not know the precise landing location for MS-09.

• Are you sure about that If the fuel fully decomposes then return to Earth is still possible but only via ballistic descent I asked a follow up. space.stackexchange.com/questions/33101/… – Antzi Dec 26 '18 at 9:48
