I think the space pins were just a theme they have not done before. It think it is just a coincidence that they were offered now. If you look at their pins weekly there are new ones each week. Generally they tie in with an upcoming holiday or event. Sometimes when nothing interesting is upcoming they use a theme, like the great outdoors ones from a few months back. The had all sorts of characters in climbing and hiking gear. This last winter they had a series of winter sports that had characters like Jessica ice-skating, Tinker Bell snowboarding, and Ursula as a Hockey Goalie. They also recetnly had a serise with characters on motorcycles. You had to love the Beauty and the Beast one.
