| DIY Satellite Platforms: Building a Space-Ready General Base Picosatellite for Any Mission [by Sandy Antunes] |
 Want to build your own satellite and launch it into space? It’s easier than you may think. The first in a series of four books, this do-it-yourself guide shows you the essential steps needed to design a base picosatellite platform—complete with a solar-powered computer-controlled assembly—tough enough to withstand a rocket launch and survive in orbit for three months.
Whether you want to conduct scientific experiments, run engineering tests, or present an orbital art project, you’ll select basic components such as an antenna, radio transmitter, solar cells, battery, power bus, processor, sensors, and an extremely small picosatellite chassis. This entertaining series takes you through the entire process—from planning to launch.

| From Eudoxus to Einstein: A History of Mathematical Astronomy [by C. M. Linton] |
 Since humans first looked towards the heavens, they have attempted to predict and explain the motions of the sun, moon, and planets. This book describes the theories of planetary motion that have been developed through the ages, from the homocentric spheres of Eudoxus to Einstein s general theory of relativity. It emphasizes the interaction between progress in astronomy and in mathematics, demonstrating how the two have been inextricably linked since Babylonian times.
