Can you go into further detail about the Defense Module? What is it? Can it be installed with the medical modules as well?

The Defense Module is still in the early planning stages, but we intend for it to be similar to the 'plug in a turret' modules on the Hull series ships; essentially taking up one a pair of slots to add turrets, e-warfare defensive weapons or similar weapons to your Endeavor's complement (at a cost of overall reduced science.)
