Propulsion Systems
This is a basic primer on the physics of conventional propulsion systems. The function of any propulsion system is to make something move forward.
http://www.ibiblio.org/lunar/school/library/physprop.html

Extractions: This is a basic primer on the physics of conventional propulsion systems. It assumes some knowledge of physics, but not much at all. I'll try and keep everything as basic as possible, but this will be a technical treatment of the subject. The function of any propulsion system is to make something move forward. Due to the conservation of momentum, this can only be accomplished by making something else move backwards. (This article ignores "reactionless" drives, as none are known to exist, and postulating them is difficult.) The heavier the stuff going backwards is, and the faster it's going, the faster you go. Generally, in order to design a spacecraft it's easiest to base your calculations off the force the drive is capable of, so that's what we'll try and calculate. The first drive we will work on is a standard reaction drive. This is a drive where you take some material, and squirt it out the back of your ship (a chemical drive, a fusion drive, ion drive, etc). The basic relation we will use is the the one between change in momentum and force: F = dp/dt In other words, the the force exerted by or on a body is equal to the rate of change in it's momentum per unit time. This doesn't seem to help us much, but it's often easier to calculate the change in momentum than the force. Now all we need to know is how much stuff (mass) we're pushing out the back of the ship, and how fast it's moving away from us.

Space Plasma Physics Modelling Page
An advanced plasma propulsion system that will create a large scale magnetic bubble around the spacecraft to ride the solar winds.
http://www.ess.washington.edu/Space/propulsion.html

Extractions: Advanced Electric Propulsion Chemical rockets have limited application for space applications due to the fact that the fuel is relatively slow (low specific impulse) relative to the speeds needed to move efficiently about the solar system. As a results chemcial systems are massive, and the trip times for missions are very long. Research at UW in this area is for the development of faster propellants that can provide substantial reductions in cost and trip time. To achieve these efficiencies plasma systems (i.e. charged particles) are required where electric and magnetic field can be used to accelerate the plasma propellants to speeds more than an order of magnitude faster than can be achieved by chemical rockets. The systems below detail devices under active development. Robert M. Winglee High Power Helicon is an electrodeless plasma thruster that is able run at kW to 100's kW to produce thruster levels as high as several Newtons of force, at high power and gas effciency.

Basics Of Space Flight
The goal of this training module from the Jet propulsion Laboratory is to provide an aid for identifying and understanding the general concepts associated with space flight in general and deep space missions in particular.
http://www.jpl.nasa.gov/basics/

Extractions: T he people of Caltech's Jet Propulsion Laboratory (JPL) create, manage and operate NASA projects of exploration throughout our solar system and beyond. Basics of Space Flight is a training module designed primarily to help JPL operations people identify the range of concepts associated with deep space missions, and grasp the relationships these concepts exhibit. It also enjoys popularity among high school and college students, as well as faculty, and people everywhere who are interested in interplanetary space flight. This website attempts to offer a broad scope, but limited depth, as a background for further investigation; many other resources are available, of course, for delving into each of the topics related here. Indeed, any one of these topics can involve a lifelong career of specialization. This module's purpose is met if the participant learns the scope of concepts that apply to interplanetary space exploration, and the relationships among them. Basics of Space Flight is intended to be used online via the worldwide web (http://www.jpl.nasa.gov/basics). Links to external sites provide further depth to many topics. There are interactive quizzes to let you check your own progress (no records are kept). No academic credit is offered for completion.

Marc G. Millis The ideal interstellar propulsion system would be one that could get you to other stars as quickly and comfortably as envisioned in science fiction. Before this can become a reality, two scientific breakthroughs are needed: discovery of a means to exceed light speed, and discovery of a means to manipulate the coupling between mass and spacetime. This article explains why these breakthroughs are needed and introduces the emerging possibilities that may eventually lead to these breakthroughs. It should be noted that either of these breakthroughs by itself would have revolutionary consequences which would be of enormous value.

Unconventional Spacecraft Propulsion
alternative spacecraft propulsion concepts to meet performance or mission objectives. Laser propulsion concepts have been described for several decades.
http://www-phys.llnl.gov/clementine/ATP/Laser.html

Extractions: The Special Studies Program (within ATP) has examined alternative spacecraft propulsion concepts to meet performance or mission objectives. Laser propulsion concepts have been described for several decades. The laser beam is used to heat a propellant with the energetic expansion driving the craft. A series of ATP devised tests were conducted in which a laser beam was directed at a pusher plate with machined paraboloid dimples. Light was focused by each dimple on a spot behind the plate. The focused beam heated air pockets and the expanding pockets imparted a thrust to the plate. This concept provides respectable thrust in the atmosphere. In space (vacuum) the dimpled plate is jettisoned to expose a block of solid propellant which is ablated by the laser beam to produce thrust.
