Publisher's Synopsis
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A robotic spacecraft is a spacecraft with no humans on board, that is usually under telerobotic control. A robotic spacecraft designed to make scientific research measurements is often called a space probe. Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and lower risk factors. In addition, some planetary destinations such as Venus or the vicinity of Jupiter are too hostile for human survival, given current technology. Outer planets such as Saturn, Uranus, and Neptune are too distant to reach with current crewed spaceflight technology, so telerobotic probes are the only way to explore them. The book reviews the history of unmanned missions starting with the Soviet missions followed by the Americans. It also describes the design of the spacecraft and list all the probes that were launched.
