Rocket

A rocket (from Italian rocchetto "bobbin") is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space.

Long Exposure of Falcon 9 rocket launch

I find this picture interesting because it gives you a perspective of how much power the rocket uses over the course, from when it's launching to the point to where it's soaring up high in the atmosphere. It would be an amazing experience to see a rocket launch like this in person.

What is Sussle?

Sussle is the first, open visual encyclopedia. Anyone can use it.

What's a visual encylopedia?

It has beautiful images and viral videos that are way more fun than reading all the text in traditional encyclopedias.

5 reasons you should add your own images and videos:

  1. If you found Sussle interesting, then give back by adding something interesting for others.
  2. Help others learn in a fun way.
  3. Make someone else interested in this topic laugh or say wow!
  4. Become internet-famous as people like and share your post.
  5. It's super easy, so it won't take more than a minute.
