As space exploration advances, scientists develop technologies to observe, record, and use information gained in those explorations. This book looks at seven modern space technology wonders--the Great Observatories (orbiting telescopes such as Chandra X-Ray Observatory), the International Space Station, Earth-observing satellites used in GPS tracking, weather tracking, communications, and other applications, technology used in the search for lunar water and the development of human settlements on the Moon, Mars Rovers, New Horizons (mission to explore the outer reaches of our solar system, and developing rocket technology for exploration beyond our solar system.
