Space Exploration is a hunt to use space travel to find out the nature of the cosmos ahead of Earth. in view of the fact that ancient times, people have dreamed of leaving their home planet and exploring further worlds. In the later half of the 20th century, that dream became realism. The space age began with the launch of the first artificial satellites in 1957. A human first went into space in 1961. Since then, astronauts and cosmonauts have ventured into space for ever-greater lengths of time, even living aboard orbiting space stations for more than a year. Two dozen people have circled the Moon or walked on its surface. At the same time, robotic explorers have journeyed where humans could not go, visiting all but one of the solar system’s major worlds. Unpiloted spacecraft have also visited a host of minor bodies such as moons, comets, and asteroids. These explorations have sparked the advance of new technologies, from rockets to communications equipment to computers. Spacecraft studies have yielded a bounty of scientific discoveries about the solar system, the Milky Way Galaxy, and the universe. furthermore they have given human race a new outlook on Earth and its neighbors in space.( IRA FLATOW)
The initial dare of space exploration was increasing rockets prevailing enough and consistent enough to boost up a satellite into orbit. These boosters needed more than brute force, nevertheless; they also needed control systems to guide them on the appropriate flight paths to reach their preferred orbits. The next challenge was building the satellites themselves. The satellites needed electronic components that were lightweight, yet durable enough to withstand the acceleration and vibration of launch. Creating these components required the world’s aerospace engineering facilities to adopt new standards of reliability in manufacturing and testing. On Earth, engineers also had to build tracking stations to maintain radio communications with these artificial moons as they circled the planet.....
