.. Building a bomb

What did have massive amount of energy in the ship?

The fusion orb of course. Go to the Fusion Orb Containment Facility using the middle teleport.

You can walk straight to the orb without any suits or such. Take it.

Maybe you could make a cooling container for it.

Use the helmet and fill it with something cold.

Like ice cream!

Great! Now just use it to the orb and you have your bomb.
