The Solid Boosters are small-sized boosters that can be attached to the side to any first stage that has room for boosters. These are the weakest boosters in the game.
The solid boosters, unlike the liquid boosters, once ignited can't be throttled or turned. They burn until their fuel is gone, and then automatically decouple.
