This book discusses the application of Cubesats in the exploration of our solar systems. Including the Sun, the eight primary planets and the minor planet Pluto, many moons, the asteroid belt, comets, the ring systems, the Centaurs, there is a lot to explore. Although the planets (and Pluto) have been visited by spacecraft, Earth's moon has been somewhat explored, and many of the other planets' moons have been imaged, there is a lot of “filling in the blanks” to be done. We examine the application of swarms of small independent spacecraft to take on this role. Some of the enabling technology's for cooperating swarms is examined.
