| Basic Rocket Some of the spacecrafts in the world are made for humans while others are not. Those rockets that are made for humans must provide them with air, food, water, navigation instruments, sleeping quarters, and communication equipment for sending information back to earth. It also must have a heat shield to protect the humans from the sun. The rockets that don’t carry humans can have a large range of length. One could be a few centimeters long, while another might be a few meters long depending on its mission. Rockets use 2 main engines which are the solid-propellent engine, and the liquid-propellent engine. The solid-propellent engine uses chemicals for fuel while the liquid-propellent uses liquid fuel and oxiders in different tanks. |
