In the KSP2 Feature video from Friday there were some...interesting teases including this:
At first glance this is a reference to the arecibo message:
And it probably is BUT it might also be a reference to this: *Intense music
hahaha! but none of you remember this do you? this is the Duna SSTV signal, as you can see for the past few day I have gone full conspiracy mode trying to figure this out and I have a theory.
My Master Theory:
The message at the end of this video is a nod from from the developers that a long scrapped plotline will be included, this is a paragraph from the Wiki which explains this:
Trying to find the planet in KSP1 is futile because as far as we know it was never implemented and without the other pyramids you cannot really get enough clues to figure out what you WOULD have have to do, the only thing I can make out is an orange circle and the word "Bop" which leads you to the Bop anomalies where you'll run into another dead end without more clues.
But who knows, maybe it is out there and the dev's are giggling at me as they read this.
But now we have the message from the feature, the first new message in sound in years, and while it's unrelated to the hunt for the lost planet in terms of clues, it's clearly a nod to the SSTV pyramid which should not really be important anymore.
And earlier in the feature we saw this:
Yes that's right, a planet, far beyond Eeloo, with a bunch of question marks.
Holy...
So, I can say with confidence that either the lost planet is being put in KSP 2, or that I'm going mad.
Have a nice day.
