In this AP/WISN news item Air leak at International Space Station temporarily plugged by a thumb they show a file photo of German astronaut Alexander Gerst at the Baikonur cosmodrome, making what looks like a gesture with his two hands, possibly forming the letter "K".

Question: What does it mean? Are there many hand signals used on the ISS? Is there a standard reference for such?

    $\begingroup$ From another angle it might look like an A or triangle. Maybe, he's just in the middle of gesticulating $\endgroup$ – Dragongeek Sep 3 '18 at 0:34

    $\begingroup$ Well I can tell you what it's not: A common German gesture or American one. I don't think it's standard sign language either and all other photos I can find of Gerst gesturing are easy to identify and none are similar to this. Maybe it's K for Kosmonaut? $\endgroup$ – Dragongeek Sep 3 '18 at 22:26

    $\begingroup$ I am unaware of any ISS specific sign language. I can think of some gestures that could be used, for example, when someone takes the last piece of fresh fruit from a shipment. $\endgroup$ – Organic Marble Mar 11 at 12:21

K might be short for Klaar ("Clear" in German) but:

It's the wrong way round from his perspective;

It's unlikely that the crew he is working with knows German - they are more likely to communicate in English than in Russian, but both are more likely than his mother-tongue.

If we had this as a video clip, I believe we would see him make an O shape immediatly beforehand.

    $\begingroup$ "Clear" in German is "klar", but "OK" is much more commonly used in such a situation. But without a video of the context and the full gesture, this answer is just speculation. $\endgroup$ – ahemmetter May 20 at 11:35
