Space Exploration
Space is hard to explore, because it’s really, really big. Most things in space are so far away that people we build special equipment just to see them. We use telescopes to magnify far-away solar systems, planets, and stars. Rockets send astronauts past the Earth’s atmosphere. Space probes with special cameras send back pictures of planets for scientists to study. Astronauts perform experiments in orbit around the Earth. We do all these things and more to learn more about our universe.
