Why is space travel important?

Studying the cosmos gives us an important perspective shift. When we learn about what lies beyond Earth, it gives us context for understanding our own planet. Studying the other worlds of our solar system and beyond makes it clear that Earth is a precious oasis for life.

How is space travel important?

Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.

What is the aim of space travel?

The ultimate aim of space exploration is to discover whether other planets harbour the resources that we will need when our own are exhausted, and even whether any of them — Mars, Saturn satellites, the Moon, asteroids, comets — are potentially inhabitable.

How safe is space travel?

Two types of risk, radiation and altered gravity, come simply from being in space, they said. Research has shown that both can have major negative effects on the body, and even the brain.

What is the most harmful thing in space?

En route to another world, astronauts will be bombarded with cosmic radiation: tiny, high-energy atom fragments that whiz through space and can damage cells and DNA.

1) One million Earths could fit inside the Sun – and the Sun is considered an average-size star. 2) For years it was believed that Earth was the only planet in our solar system with liquid water. More recently, NASA revealed its strongest evidence yet that there is intermittent running water on Mars, too!

Why is space travel interesting?

Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets.

Why is space silent?

In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins about 100 km above the Earth, where the shell of air around our planet disappears.
