Huge engines and tremendous power are needed to lift spacecraft. On this rocket, four boosters are attached to the main craft and they burn through all their rocket fuel in the first 2 minutes of flight. Once their fuel is gone (about 20,000 gallons), the boosters are jettisoned from a height of about 150,000 feet. (Shutterstock / Fotografff)
