Accepted Answer

Space exploration is when people and machines go into space to learn more about it. We want to know about the planets, stars, and everything else in the universe.

Question 2

Why is space exploration important?

Accepted Answer

Space exploration helps us understand where we come from and what's out there. It also leads to new inventions that can make life better on Earth.

Accepted Answer

A rocket is a kind of vehicle that blasts off into space. It uses powerful engines to push itself up and away from Earth.

Question 5

What do astronauts do in space?

Accepted Answer

Astronauts do many things like conduct experiments, fix things on their spacecraft, and learn how to live in space. They also enjoy floating in zero gravity!

Question 6

How do people breathe in space?

Accepted Answer

In space, there is no air, so spacecraft and spacesuits have special equipment that provide astronauts with air to breathe. They carry oxygen tanks just like scuba divers do underwater.

Question 7

What is the International Space Station?

Accepted Answer

The International Space Station, or ISS, is a big lab that orbits around Earth. Scientists and astronauts from different countries live and work there to learn more about space.

Question 8

How long does it take to travel to the Moon?

Accepted Answer

It takes about three days to travel to the Moon from Earth. That's how long it took the Apollo astronauts to get there in the rocket.

Question 9

What are planets?

Accepted Answer

Planets are big, round objects that orbit around a star, like our Sun. Earth is a planet, and there are seven other planets in our solar system.

Question 10

Why is the sky dark at night?

Accepted Answer

The sky is dark at night because the Sun, our main source of light, is on the other side of Earth. Without sunlight, we see the darkness of space and the stars.

Question 11

How do we know there is no gravity in space?

Accepted Answer

In space, everything floats around because there's very little gravity compared to what we feel on Earth. That's why astronauts appear to float while they're in their spacecraft.

Question 12

Can animals go to space?

Accepted Answer

Yes, animals like dogs, monkeys, and even spiders have been to space. Scientists study them to see how living things react to being in space, which helps keep astronauts safe.

Question 13

What is a telescope?

Accepted Answer

A telescope is a tool that makes faraway things look closer and clearer. People use telescopes to see stars, planets, and other objects in space.

Question 14

What is the difference between a star and a planet?

Accepted Answer

Stars are big balls of hot, glowing gases that give off light, like our Sun. Planets are cooler, and they don't make their own light; instead, they shine by reflecting the light of a star.

Question 15

Why is Mars called the Red Planet?

Accepted Answer

Mars is called the Red Planet because of its reddish color. This color comes from rusty dust on its surface, which makes it look red from far away.

Question 16

What do scientists hope to find on other planets?

Accepted Answer

Scientists hope to find evidence of life, water, or conditions where life could exist on other planets. Finding these things would help us learn if we are alone in the universe.

Question 17

What is an astronaut?

Accepted Answer

An astronaut is a person who is trained to travel and work in space. They often fly in spaceships and live in the International Space Station to explore and learn about space.

Question 18

How do spaceships travel in space?

Accepted Answer

Spaceships travel in space using rockets that push them forward. Once in space, they can keep moving because there is no air resistance to slow them down.

Question 19

What is a satellite?

Accepted Answer

A satellite is a machine that orbits around Earth or another planet. We use satellites for things like TV broadcasts, weather reports, and GPS navigation.

Question 20

Can people live on other planets?

Accepted Answer

Right now, people can only live on Earth because it has the air and water we need. Scientists are studying if places like Mars could be made safe for us to live on in the future.
