Micropropulsion is an enabling technology for microspacecraft operations by making missions possible that otherwise could not be performed. For example, the formation and maintenance of platoons of microspacecraft will require a maneuvering capability to counter orbital perturbations. Microspacecraft missions involving large spacecraft resupply, repair, or surveillance will also require maneuverability. The mission requirements for microspacecraft will be varied and in some cases a large range of capability might be required on the same spacecraft. Micropropulsion systems must be extremely versatile to address these requirements.
It is clear that there is a need for micropropulsion systems from high-thrust chemical engines to high specific impulse electric thrusters to fulfill specific missions just as for larger spacecraft. It is becoming increasingly evident that microspacecraft will require efficient propulsion systems to enable many of the missions currently being investigated. The systems constraints on mass, power, maximum voltage, and volume with which microspacecraft will have to contend pose several challenges to the propulsion system designer. Micropropulsion concepts that address these limitations in unique and beneficial ways will be of interest to the microspacecraft community.
Written by leading experts in the field, this book shows the state of the art in micropropulsion concepts and activities at the early stages in the development of this new and exciting research area.
Micropropulsion is an enabling technology for microspacecraft operations. This work reports on the state of the art in micropropulsion concepts and activities, with survey papers, and sections on electrothermal, electrostatic, and electromagnetic thrusters and components. Topics include system considerations and design options, predicted performance and systems analysis of the free molecule micro-reistojet, and very low-power arcjets. Micci teaches aerospace engineering at Pennsylvania State University. Ketsdever is on the research staff at the Air Force Research Laboratory's Propulsion Directorate. Annotation c.

Micropropulsion for Small Spacecraft, Vol. 187
(This review is of the EPUB version, which I created myself.)
The greatest strength of this book is its focus'it deals with the Saturn launch vehicles and very little else. As the title suggests it's also fairly technical and doesn't cater to the casual reader, so some basic knowledge of how rockets work is probably required.
The stories of the engines and stages are the most fascinating, with many accounts of new problems and their eventual solutions. Most surprising to me was the challenges associated with liquid hydrogen. At −253°C (20K), if the fuel tanks or fuel lines aren't properly insulated, it will liquefy air and solidify liquid oxygen, both of which are bad news. Another bit of scary hydrogen trivia:
There was an added, perverse character about leaks that produced hydrogen fires'in daylight, the flame was invisible. It was possible to inadvertently blunder into the searing flame. … But how to detect an invisible fire? … SACTO had a special examination crew, outfitted with protective clothing and equipped with brooms. The men "walked down" the stage, from the top scaffolding to the bottom, extending their brooms ahead of them. If the broom suddenly sprouted into flame, the men knew they had discovered a hydrogen leak. Still, accidents could happen, even when extra precaution was taken.
On the non-technical side, I was surprised to learn how many different private contractors were involved. I had imagined that the Saturn V was built by NASA itself, but actually each stage was built by a different contractor, who in turn had many sub-contractors. The one area where there doesn't seem to have be much competition is rocket engines, all of which were built by Rocketdyne, who also went on to build the SSME.
Next, I'm going to read Chariots for Apollo: A History of Manned Lunar Spacecraft to learn more about the payload of the Saturn V, the CM and LM.
