For thousands of years, people have gazed at the night sky, and the stars.  Many dreamed of exploring other planets, but there was no way of traveling there.  The invention of rockets have allowed us to travel into space, and land on other planets.  It was only during the 1950’s that the technology for space rockets was fully developed. It’s only been about 50 years since the first satellite was launched and revolutionized the way we live.  It’s difficult to predict the future, but one thing is for certain – we will continue to develop faster and more versatile spacecrafts to transport us further into space.  Perhaps you will be the one to build colonies on planets and set up exciting scientific missions.
