Hella

Gerrold, David
"Hella is a planet where everything is oversized--especially the ambitions of the colonists. The trees are mile-high, the dinosaur herds are huge, and the weather is extreme--so extreme, the colonists have to migrate twice a year to escape the blistering heat of summer and the atmosphere-freezing cold of winter. Kyle is a neuro-atypical young man, emotionally challenged, but with an implant that gives him real-time access to the colony's computer network, making him a very misunderstood savant. When an overburdened starship arrives, he becomes the link between the established colonists and the refugees from a ravaged Earth. The Hella colony is barely self-sufficient. Can it stand the strain of a thousand new arrivals, bringing with them the same kinds of problems they thought they were fleeing? Despite the dangers to himself and his family, Kyle is in the middle of everything--in possession of the most dangerous secret of all. Will he be caught in a growing political conspiracy? Will his reawakened emotions overwhelm his rationality? Or will he be able to use his unique ability to prevent disaster?"--Provided by publisher.

Celestial mechanics and astrodynamics: theory and practice

Gurfil, Pini,Seidelmann, P. Kenneth
This volume is designed as an introductory text and reference book for graduate students, researchers and practitioners in the fields of astronomy, astrodynamics, satellite systems, space sciences and astrophysics. The purpose of the book is to emphasize the similarities between celestial mechanics and astrodynamics, and to present recent advances in these two fields so that the reader can understand the inter-relations and mutual influences. The juxtaposition of celestial mechanics and astrodynamics is a unique approach that is expected to be a refreshing attempt to discuss both the mechanics of space flight and the dynamics of celestial objects. “Celestial Mechanics and Astrodynamics: Theory and Practice” also presents the main challenges and future prospects for the two fields in an elaborate, comprehensive and rigorous manner. The book presents homogenous and fluent discussions of the key problems, rendering a portrayal of recent advances in the field together with some basic concepts and essential infrastructure in orbital mechanics. The text contains introductory material followed by a gradual development of ideas interweaved to yield a coherent presentation of advanced topics.
