The Explosive Module is a payload used in Mission 7 and Mission 22, to destroy the enemy spy satellite, and to destroy a malfunctioning Resupply Module respectively. Once docked, the Explosive module can be detonated by pressing the "Destruct" button. Therefore, it is the only known weapon in the game.
Like the Space Telescope, it is a thruster-only object. However, unlike the Space Telescope, its thrusters do provide motion in four directions.
It appears to be the most smallest payload in the game. It can be launched with Fairing Aero.
