I know there are a bunch of Easter Eggs in the game, but I noticed there was a small amount that's present everyday.
So I came up with a batch of Easter Eggs any Astronut would love.

Voyager

Dedicated to Voyager 1 and 2
Would Appear in Any Binary Star System. Appears in Wormhole Sectors, undetectable by radar.

New Horizons

Would appear in any planet far away from it's star.

Space Shuttle

Would Appear hidden in Itan J-11

Just a suggestion, ignore if you want to

I think the developers have other things to worry about right now.
The playerbase would rather see more useful content.

+2 I love the horizons and voyagers ideas, More likely the Devs will go for the new horizons idea most definetely.
