Detailed explanation-1: -First, with telescopes, then with satellites, then space rovers, and ultimately with manned spacecraft.
Detailed explanation-2: -Star Wars would have you believe that the greatest challenges to space travel is asteroids, lack of resources like water or fuel, or even the threat of unfriendly, intelligent alien life. But in reality, scientists are finding that the biggest obstacle to today’s space travel is dust. Yes, space dust.
Detailed explanation-3: -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-4: -Improving health care. Protecting our planet and our environment. Creating scientific and technical jobs. Improving our day-to-day lives. Enhancing safety on Earth. Making scientific discoveries. Sparking youth’s interest in science. Cooperating with countries around the world. 11-Dec-2020
