I'm always a sucker for these mysterious secret messages left by developers.
One idea I have:
1. Top row is likely just to establish the message's image width for decoding, no big deal.
2. Kerbal system with a rocket shown launching from Kerbin, easy - but here's where I put on the tinfoil hat - the rocket could be an interstellar torchship. The shape of the plume made me think of all the times they have shown the torchship in their videos.
3. The kraken is seen destroying the ship and you could leave the interpretation at that... BUT... this could also represent the idea of using high speed time warp (which is now possible in KSP2)
4. So while risking the wrath of the kraken - the ship travels 22 [units of something] to a destination - my theory is that these units could represent light years.
5. The line then points to the centre of a 5-body system of some kind. Time to add another tinfoil hat - the left symbol is the same shape as Kerbol star but with a hollow centre. This means one thing to me - a black hole. Therefore, I theorize that this is a quintuple star system with a black hole at its centre and if we travel to this place, perhaps in orbit around the black hole, we will discover the ancient kraken race.

I know it's far fetched, but it would be an amazing challenge to discover if true
