Legos return to the Moon! I built the following Lego models of NASA’s Project Constellation spacecraft and lunar lander when I would take breaks from my PhD exam reading schedule. The Orion spacecraft includes a detachable solid rocket booster, and it can be mated to the Altair lunar lander craft. Orion carries three minifig astronauts, and the Altair has room for one minifig astronaut. I based my Lego models on some of the computer generated mockups shown on NASA’s Constellation program website here.
