As of my last update in 2023, the LEGO 60351 set is part of LEGOs City space-themed line. While I do not have specific details about this precise set since it was not mentioned in my last update, LEGO City space sets typically revolve around space exploration themes, including rockets, lunar rovers, mission control centers, and astronaut minifigures. These sets encourage imaginative play and are designed to inspire interest in space exploration and science amongst children. They often contain various features like working parts (e.g., launching rockets, opening cargo bays) and detailed minifigure accessories that enhance playability. If 60351 follows the trend of its series, it would likely offer a creative and educational building experience that combines the thrill of space exploration with the hands-on creativity LEGO is known for. For the most current information, including specifics about the sets features, piece count, and minifigures, checking the official LEGO website or trusted retailers would provide the latest details.
