Rockets

Rockets are any vehicle that are used to send payloads into space. They are the rocket as a whole, they are not the individual sections that make up the rocket.

So far, all rockets involve staging, that is, ejecting fuel-spent stages to lighten the weight while flying into orbit. All space-capable countries have their own rocket designs. You can create your own rocket in Space Agency by mixing different parts together, but make sure it can get the payload into orbit.
