Labels:text | screenshot OCR: ROCKET POWER SPACE TECHNOLOGY LAUNCH The force that pushes a rocket forward is A ROCKET called thrust. The strength of the thrust depends on how much exhaust is produced and the rate at which it escapes. Thrust accelerates the rocket, increasing its speed. The acceleration depends also on the rocket's mass: the heavier a rocket, the more thrust it needs to reach space. The craft continues to accelerate as long as the rocket engines are firing and providing thrust. Each rocket engine contains either a solid- or a liquid-propellant, but sometimes a complete rocket will have both types of engines as different stages. SATURN V Nuclear-powered rockets have been proposed, The US Apollo missions were as they would be extremely energy efficient, launched using the powerful but fears over the safet ...
