The EM-J4-P3502 Zero-G package was developed for the EM-J4 MARI Series Drone, it became available in YE 35.

The J4-P3502 gives the EM-J4-2a drone the ability to maneuver in a zero-g environment. It consists of eight rotating ion thrusters. They can accelerate the drone at a maximum rate of 10 m/sec². Typically the drone will operate at slower rates of acceleration. The rate of acceleration decreases if the drone is carrying something.
