LISA Propulsion Module, 1/58 scale

This is the propulsion module for the proposed NASA/ESA LISA spacecraft, which is available at the same scale here. A stack of three modules, each containing a single LISA spacecraft, would launch the constellation into an Earth-trailing orbit. The three spacecraft would then form the vertices of an equilateral triangle more than a million kilometers on a side to detect passing gravitational waves, ripples in space-time predicted by Einstein's general theory of relativity.
