In our lives, we have witnessed a great adventure. Amazing machines have been launched into space to explore the heavens. The machines have returned some
outstanding images of our solar system, our galaxy, and the universe. These visions have expanded our horizons and helped us to appreciate the magical
extent of the sky above us. As the machines have marched forth into space, the
people of Earth have also developed a new appreciation of our world and the
awesome universe we live in. Once again, the human race is demonstrating its tenacious will to march forth and seek out new, exciting vistas.
