In the game, the platform had "several kilotons of nanological material", which is more or less just technobabble, because "kilotons" in a military context usually refers to "kiloton of TNT equivalent", describing the explosive power of a nuclear warhead. Nanological weapons wouldn't explode, though, but rather work like viruses which destroy living tissue or technology or both.
Sarcastic Username corrected me on my energy estimate, though, actually a modest deceleration would suffice to send an object in geosynchronous orbit on a collision course with earth's surface.
