ELI5: Explain Like I'm 5

Spacecraft

A spacecraft is like a big machine that humans build so we can travel through space. Space is the big dark place outside of our planet Earth where the stars and the moon are.

A spacecraft needs a lot of things to work, like fuel, food, water, and air. We can't breathe in space because there is no air there, so a spacecraft needs to bring its own air with it.

A spacecraft has a special part called an engine that makes it move through space. The engine uses fuel like a car uses gas to move forward.

Some spacecraft have robot arms that can move things around in space. Others have different tools and instruments to help scientists learn more about space.

When humans go on a spacecraft, we have to wear special suits called spacesuits that protect us from the lack of air, the hot and cold temperatures, and other dangers of space.

The first spacecraft was sent into space in 1957 by the Soviet Union. Now, many countries and companies make spacecraft to explore space and learn more about the universe.
