A Space Academy student and his time-travelling robot stop an evil villain from taking over the Solar System in this children’s sci-fi classic. Fourteen-year-old Jeff Wells, a cadet at the Space Academy on Mars, is in danger of being kicked out unless he can improve his grades. With a little help from the academy’s commandant, Jeff finds a robot named Norby to help him study. But Norby’s no ordinary robot. He has the only mini-anti-gravity device in existence. Norby’s special abilities suddenly come in handy when a villain named Ing targets Jeff’s older brother in his quest to conquer the Solar System. When Ing takes over Manhattan Island, renaming it “the Kingdom of Ing,” Norby and Jeff put studying aside to teach Ing a lesson!

"Geologic Monitoring is a practical, nontechnical guide for land managers, educators, and the public that synthesizes representative methods for monitoring short-term and long-term change in geologic features and landscapes. A prestigious group of subject-matter experts has carefully selected methods for monitoring sand dunes, caves and karst, rivers, geothermal features, glaciers, nearshore marine features, beaches and marshes, paleontological resources, permafrost, seismic activity, slope movements, and volcanic features and processes. Each chapter has an overview of the resource; summarizes features that could be monitored; describes methods for monitoring each feature ranging from low-cost, low-technology methods (that could be used for school groups) to higher cost, detailed monitoring methods requiring a high level of expertise; and presents one or more targeted case studies."--Publisher's description.
