A couple of years ago I started a short-lived feature here to highlight official sets built at microscale. I guess I let that slide, but for today's 40th anniversary of the moon landing, let's take a look at 7468 - Saturn V Moon Mission.
Back in 2003 LEGO released a line of six sets in the Discover - NASA theme. These were at a variety of scales, ranging from a ~1/8 scale Mars Rover, to a fig-scale Apollo 11, to a microscale International Space Station. This series was part of a partnership among LEGO, NASA and the Planetary Society, including a contest to name the Mars Rovers and, IIRC, images of minifigs who were on one of the Mars Rovers. Focusing on this set, it has models at 4 different scales, including three different microscales of the Saturn V, the Lunar Command Module, and the Lunar Lander (also a fig-scale Lunar Rover). This set had 178 pieces and cost $20 in the US. I don't recall if these sets had worldwide release or not - they're US-centric, but the moon mission is (post-cold-war) better seen as an adventure of mankind than of one nation.
