Yann,
From what I've seen, NASA really hasn't had that spark for years, the Apollo missions to the Moon was the last spark for youngsters to imagine to travel to another heavenly body in reallity, now we have robots doing the dirty work like going to Mars, Venus, Jupiter's Moons but no Buck Rodgers in the seat and I think that's what is hurting the Space Modeling draw, there is the Star Terk types of modeling but no actual reallity space modeling in years, I've seen modelers bust their chops when Monogram & Revell released the Space Shuttle kits back in the late 70's, early 80's but now you can't get the modelers to take a second look at the kit unless the modeler is really into the Space Program, and they are a breed all their own and the kits are either a scratch built, or a very high Dollar resin kit, or a hard to find out of production kit from the late 1960's, the model companies are more into the Automotive kits then any other type because more of the young individuals are into their computer games like X-Box, Game Cubes, Nintendo's then into modeling anymore, and when they take a break from the games and go into modeling it's eazier for them to comprehend working on a car then an airplane, tank or spaceship so they'll get a car kit then a model of the space shuttle or a Patton tank or a airplane
I'm not against the Space Program, Heck I was a part of it, I worked Magellion, Galliao, TES, Commerical Titan, Titan II & IV, and my father worked with NASA during the Gemini & Apollo Missions and worked Viking and more various other satelites that where built by Martin Maretta (now Lockheed-Martin), as with my brother who still works for Lockheed-Martin
