Orbital mechanics is a cornerstone subject for aerospace engineering students. However, with its basis in classical physics and mechanics, it can be a difficult and weighty subject. Howard Curtis - Professor of Aerospace Engineering at Embry-Riddle University, the US's #1 rated undergraduate aerospace school - focuses on what students at undergraduate and taught masters level really need to know in this hugely valuable text. Fully supported by the analytical features and computer based tools required by today's students, it brings a fresh, modern, accessible approach to teaching and learning orbital mechanics. A truly essential new resource.
