More than 300 years ago, a scientist named Isaac Newton laid out three basic laws that describe the way things move. One of the laws says that for every action, there is an equal and opposite reaction. This is the most important idea behind how rockets work. If you see pictures or videos of a launch, you’ll see exhaust streaming out the bottom of t...
It’s not that simple. Earth’s gravity is still pulling down on the rocket. When a rocket burns propellants and pushes out exhaust, that creates an upward force called thrust. To launch, the rocket needs enough propellants so that the thrust pushing the rocket up is greater than the force of gravity pulling the rocket down. A rocket needs to speed u...
Let’s say you want to launch a satellite that orbits Earth. The rocket will launch, and when it gets to a specific distance from Earth, it will release the satellite. The satellite stays in orbit because it still has momentum—energy it picked up from the rocket—pulling it in one direction. Earth’s gravity pulls it in another direction. This balance...
If you’re trying to get to another planet, you’ll need a fast-moving rocket to overcome Earth’s gravity. To do that, you’d have to speed up to around 25,000 mph. But you’ll also need to figure out the best time to leave Earth to get to that planet. For example, Mars and Earth reach their closest distance to each other about every two years. This is...
