Here's the quote from the http://www.genesismission.org home page:
JPL engineer is in the running for an award for "work so revolutionary that it has changed the direction, if not completely reversed, their field."
Martin W. Lo of the Jet Propulsion Laboratory, Pasadena, Calif., was nominated for the Discover Magazine Innovation Award in the field of Aerospace for his work on applying "chaos theory" to the design of trajectories like the one used by Genesis, computed using his LTool which has defined what Lo calls an "InterPlanetary Superhighway": paths through space that depend on balanced-gravity points between planets. This helps spacecraft fly though the solar system on very little fuel. Team member Kathleen Howell, professor of aeronautics and astronautics, Purdue University, West Lafayette, IN, joins him in his nomination.
Meet Martin Lo in this interview that takes the reader along the "InterPlanetary Superhighway" and into the changing world of engineering.
Low gravity zones between planets -- but honestly don't these things cahnge minute to minute the planets are rotating what you may save in fuel economy you would loose as you had to keep place with your low gravity portal and the faster the planet moves the more impractical this sounds. Say for example we want to chart a flight to mercury it travels around the sun in 88 days I think how many rorations would it achieve before you arrived? 10 - 15 trying to stay in it's gravity well would not be possible at this time.
What then about Mars 2 years of flight I'm told to get there using the straightest route and compensating for orbit -- how would you in a two year flight in this highway?
In theory it may sound reasonable but the application is nott very practical sounding
I'll have to give this some more thought.
