LISA spacecraft, 1/48 scale

3D printed in deep yellow, richly colored nylon plastic with a smooth finish.
Product Description
Special request for a larger 1/48 scale model.

This model is one of three spacecraft of a proposed constellation that would operate as a space-borne gravitational wave detector. Called the Laser Interferometer Space Antenna (LISA), the project was studied in great detail as a collaborative mission between NASA and ESA, although neither agency decided to proceed with it. Space is the best place to detect gravitational waves, so sooner or later a mission similar to LISA will fly (in my humble opinion, anyway). 

The plan for LISA was that three identical spacecraft would fly in an Earth-trailing orbit. Each would form the vertex of an equilateral triangle spanning several million kilometers. The spacecraft would fire lasers at each other to measure their relative displacements with picometer (trillionth of a meter) accuracy, allowing scientists to measure the tiny distortions of space-time caused by a passing gravitational wave.

The propulsion module for the spacecraft is available at the same scale here.

LISA's gravitational wave sensor is a "proof mass," an object allowed to follow a pure free-fall trajectory that the spacecraft tracked. A full-scale model of the proof mass is available here.
