Artist's impression of the LISA Technology Package (LTP) to fly on board LISA Pathfinder.
The partly transparent view reveals the two proof masses: 46-mm cubes of a gold-platinum alloy, housed in individual vacuum cans. The cubes serve both as mirrors for the laser interferometer (red light-paths) and as inertial references for the drag-free control system of the spacecraft.
