What are the key milestones in human space exploration?

Human space exploration is like taking a trip from your house to another planet, but instead of walking or riding a bike, we use spacecraft and rockets.

The first big milestone was when humans left Earth for the first time. This happened in 1961, when Yuri Gagarin, a Russian astronaut, went all the way around the Earth in space, like going on a very long airplane ride, but outside of an airplane!

A few years later, in 1969, humans took their biggest step yet: landing on the Moon. A group of astronauts from the United States walked on the Moon’s surface, leaving footprints that stayed there for a long time, like stepping into a giant sandbox and never coming back.

After visiting the Moon, people started going farther out in space. In 1981, the Space Shuttle was launched, it worked like a reusable spaceship that could take astronauts to space and bring them back again, like a school bus that goes on trips and comes back every day!

These milestones helped us learn more about space and showed how far humans can go!
