They can create Planetary Shields on planets to resist attacks from space. Massive amounts of energy are required for a Planetary Shield. If the shield becomes ineffective, it will leave the planet exposed to serious threads from space. Additionally, the number of Shield Generators that can be built on a planet is limited. Planetary Shield can only resist damage from space, it cannot defend ground damage.
Planetary shield generators behave similarly to energy exchangers and batteries in that, if the power grid can't fully support their charging, they will use less energy instead of causing the power grid to go under 100% satisfaction.
If two generators are placed nearby, their coverage areas will melt together rather than simply overlapping, increasing coverage considerably.

Player Tips & Tricks
Relay Stations are unable to create new planetary bases on any portion of planet covered by a planetary shield of any strength; even the pale blue fringes of the shield will prevent landings.
Because planetary shields can melt together, landings via relay station can be prevented with just 8 shields minimum (typically 2 on the poles and 6 reasonably evenly spaced on the equator).
