Huh? Mars Mission, Power Miners, Alien Conquest, and Galaxy Squad were all 6-12 years ago; Atlantis is also nearly a "space set" in most of its design elements.

One of the Master Builder lines was space themed. The Lego Movie lines are admittedly halfway "branded", but also have a lot of space designs.

I’m building the apollo sets now: the lunar lander and the Saturn V rocket- definitely not “branded”? Also I think an ISS set was just released?
