Question 9

What is a space station?

Accepted Answer

A space station is a large spacecraft where astronauts can live and work for long periods. It orbits the Earth, and people from different countries use it to do research and experiments.

Question 10

What is Mars, and why do we want to explore it?

Accepted Answer

Mars is the fourth planet from the Sun and is often called the 'Red Planet' because of its color. Scientists explore it to find out if life ever existed there and to learn more about our solar system.

Question 11

What are rovers, and what do they do on Mars?

Accepted Answer

Rovers are robot machines that move around on planets like Mars. They take pictures, study rocks, and search for signs of life to help scientists understand Mars better.

Question 12

How do we send pictures from space back to Earth?

Accepted Answer

Pictures from space are sent back to Earth using radio waves. Satellites and spacecraft take the pictures and then send the data to antennas on Earth, which receive the signals and turn them into images.

Question 13

Who was the first American to walk on the Moon?

Accepted Answer

The first American to walk on the Moon was Neil Armstrong. He took his famous step on the Moon during the Apollo 11 mission in 1969.

Question 14

What is the International Space Station, and who uses it?

Accepted Answer

The International Space Station (ISS) is a giant space station where astronauts from around the world live and work together. It's used for scientific research, and countries like the USA, Russia, and Japan help operate it.

Question 15

Why is exploring space important for life on Earth?

Accepted Answer

Exploring space helps us create new technologies, understand natural disasters, and protect our planet. It also inspires us to think about our future and how to explore beyond Earth.

Question 16

What is the solar system?

Accepted Answer

The solar system is our neighborhood in space, with the Sun at its center and planets, moons, asteroids, and comets orbiting around it. Earth is one of these planets, and exploring space helps us learn more about this system.

Question 17

What is an astronaut, and what do they do?

Accepted Answer

An astronaut is a person trained to travel and work in space. They conduct experiments, repair spacecraft, and explore parts of space that we want to understand better.

Question 18

When did space exploration begin?

Accepted Answer

Space exploration began in 1957 when the first satellite, Sputnik, was launched. Since then, many missions have taken place to explore space further.

Question 19

What is a telescope, and how does it help in space exploration?

Accepted Answer

A telescope is a tool that makes faraway objects look closer, allowing us to see stars and planets from Earth. Telescopes help scientists explore space by showing detailed images of things we can't see with our eyes.

Question 20

Is there life on other planets?

Accepted Answer

We don't know yet if there is life on other planets, but scientists are searching for signs. By studying planets like Mars and distant moons, we hope to discover if life exists elsewhere in the universe.
