About LEGO Space Exploration Telescope

Building this 278-piece set offers three distinct construction experiences, each with its own mechanical features and interactive elements. The telescope model includes a functioning light projection system, while the microscope features an illumination mechanism, and the UFO design incorporates a directional light beam.

The main telescope model stands 27 cm tall and includes a detailed solar system display alongside the viewing apparatus. Three interchangeable decorated lenses - featuring planet, star and Moon designs - can either project images onto surfaces or be viewed through the microscope build. Each model incorporates a light brick with push-button activation, powered by included batteries.

Interactive Features

The set's lighting system serves different functions across the three builds. The telescope projects the lens designs as images, the microscope illuminates specimens for viewing, and the UFO creates a focused light beam effect. This electronic component adds a functional element beyond basic brick construction.

The three models cannot be built simultaneously as they share the same piece collection. Suitable for ages 8 and above, the set encourages rebuilding and exploration of different scientific instruments and space-themed designs through its 3-in-1 format.
