Detailed explanation-1: -Direct and indirect benefits of space exploration New technologies that can be utilized in other industries and society (such as the development of communications satellites) Improved knowledge of space and the origin of the universe. Cultural benefits.
Detailed explanation-2: -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.
Detailed explanation-3: -Orbit is a balancing act Orbit is the easiest way of going permanently to space. It’s a big first step on the way to leaving the gravity of earth behind. Being in orbit means you are balanced – between gravity pulling you down and your own momentum flinging you into outer space.
Detailed explanation-4: -Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system.
