"With DIY Satellite Platforms, you too can safely launch a small basic satellite into space safely and with satisfactory results. The book is a quick read, only 80 pages long, short of formulas and long on practical information, and should inspire physics and science teachers and students to create some hands-on space experience for themselves or their classes."
