61. Ion Propulsion Helps Spacecraft Cruise Solar System On The Cheap
    The Dawn mission to the asteroid belt will do twice as much for a third of the cost thanks to the steady stream of xenon used to propel the probe.

The key: Ion propulsion only needs a tenth of the fuel of a chemical rocket system to reach the same destination, and that means a smaller rocket and a lot less fuel is needed to launch missions, such as the Dawn probe. The miserly use of propellant will allow the Dawn probe to become the first to orbit two separate objects in this case, the asteroid Vesta in 2011 and the dwarf planet Ceres, where it's expected to arrive in 2015. Ion propulsion uses positively charged atoms, or ions, to propel a spacecraft. An electron gun is used to knock electrons from a reservoir of xenon atoms, turning them into ions. Then, two charged plates accelerate the ions and eject them from the back of the rocket engine at speeds of 35 kilometers per second, or about 77,000 mph. To avoid accumulating a negative charge, the probe shoots electrons back into the stream of xenon ions leaving the engine.

    http://www.astrodigital.org/space/nuclear.html
    
    Extractions: For those who are interested in the exploration and development of space by humans, nuclear propulsion technology is a very attractive option. Why? Compared with the best chemical rockets, nuclear propulsion systems (NPS's) are more reliable and flexible for long-distance missions, and can achieve a desired space mission at a lower cost. The reason for these advantages in a nutshell is that NPS's can get "more miles per gallon" than a chemical rockets. If NPS's were analogous to a 1998 Honda Civic, then your best chemical rocket would be a gas-guzzler from the 1950's.

    Extractions: This book intends to provide an introduction to jet propulsion at the undergraduate level. A jet engine is a type of air-breathing internal combustion engine often used on aircraft. The principle of all jet engines is essentially the same; they accelerate a mass (air and combustion products) in one direction and, from Newton's third law of motion, the engine experiences thrust in the opposite direction. Frank Whittle received the patent in 1930 for a jet engine. Hans von Ohain received the German patent in 1935. The first jet aircraft was the Heinkel He178 flown in 1939 with a von Ohain engine producing 4.9kN of thrust. My father told me his father ,Robert Bolton first patented the jet engine in 1917 using the name of his brother in law Stocker Harris ,we have a letter from the editor of Flight magazine saying that his patent was 17 years ahead of Whittle's.He also patented the "Bolton highspeed circuit breaker".I wouldn't know how to rescearch these "facts",I do know that he worked for the English electric company and Allan West electrics,where his designs where in the name of the firms he worked for. The main types are the

Now, at the beginning of the 21st century, aerospace engineers are devising innovative ways to take us to the stars , including light propulsion nuclear-fusion propulsion and antimatter propulsion. A new type of spacecraft that lacks any propellant is also being proposed. This type of spacecraft, which would be jolted through space by electromagnets , could take us farther than any of these other methods.

    http://ocolly.com/2008/01/18/rocket-propulsion-research-might-advance-military-t
    
    Extractions: Staff Writer Oklahoma State researchers are developing a state-of-the-art propulsion system for the United States Defense Advanced Research Projects Agency. If successful, the propulsion system will be featured in sophisticated unmanned aircraft small enough to fit into a soldier’s pocket. “What we want the infantrymen to be able to do is pull a pack of six or so out of their pocket and have them ready for use,” Jamey Jacob, an associate professor of mechanical and aerospace engineering, said. The aircraft would be used for surveillance purposes and allow soldiers to inspect hostile areas before moving through them. Jacob and his team have been working on the project since the end of August. “It’s a new propulsion technology to be used by micro and nano-unmanned aerial vehicles, or UAV,” Jacob said. “By micro, we mean smaller than a foot, and by nano, we mean smaller than six inches.” Jacob’s project would provide a significant upgrade over the UAV equipment currently available to soldiers.

78. Canonical List Of Space Transportation Methods
    Attempts to list all known space propulsion methods.  
    http://www.geocities.com/danielravennest/CanonicalList.html
    
    Extractions: Space Transportation and Engineering Methods Version 0.79 July 26, 2001 by Dani Eder DaniEder@aol.com This document is a an attempt list of all known space transport and space engineering methods. It includes only those methods whose underlying physical principles are understood (i.e. no Star Trek warp drives). It is the product of a number of years of collecting and, occasionally, inventing them. I am motivated by a desire to see civilization expand into space and my frustration by the slow pace of progress to date. Most current space vehicles and projects use techniques that existed in the 1950's and 1960's. Some new ideas were developed as early as 1960, but have not been put into used even today. From the 1970's to today many additional ideas have been generated. Most of these have received scant attention. By disseminating information on these ideas, I hope others will realize the vast untapped potential contained in these ideas. This draft (version 0.79) lists all the concepts I am aware of, with at least a basic description of each. As you can tell by the version number, which is less than one, this is still very much a work in progress. Later versions of this document are intended to flesh out each method with improved descriptions and current references. If you know of a method which is not on this list, I would appreciate being informed of it. If you have references or text descriptions on a concept, they would be appreciated also. Some related information on the basics of space transport, the forces and energies used, and space project engineering are included. Editorial comments and material that needs lots of editing appear in square brackets.
