We humans are motivated to dream, to explore, to discover, to learn. "Dream no small dreams for they have no power to move the hearts of men." -- Johann Wolfgang von Goethe “It is difficult to say what is impossible, for the dream of yesterday is the hope of today and the reality of tomorrow.” -- Robert H. Goddard

Wonders of Robotic Space Exploration “Humans in space” have generated a grand public interest and excitement. Yet, it is robotic space explorations that have paid the biggest dividends of remarkable new knowledge and useful applications. E.g., Solar physics and space weather. Planetary exploration. Astronomy and astrophysics. Earth remote sensing, climate and weather. Global Positioning System. Communication and broadcasting. Military intelligence. Today we’ll touch on only a few exciting experiments.
