The High Orbit Debris Object Reclaimer (or H.O.D.O.R) is a reliable way to acquire Research Parts from Droppods, by using a rocket to shoot them down from Orbit.

Once built, the launchpad will require 100,000 power to construct the rocket and 50 High Octane Fuel to fuel it, after which the rocket will launch into space. As soon as the rocket reaches the Planets orbit, a Droppod will appear and crash to the surface ready for being looted.
