Low Energy Orbits In the Solar System, Intel Science Talent Winner Describes Her Work Options

[lyford]

Erika DeBenedictis, 18, of Albuquerque, N.M., with her project developing a software navigation system to help improve spacecraft travel through the solar system.

Debenedictics is talking to the Boeing Company with the hopes of running her software on their equipment, to see how satellites and other spacecraft would react to its station keeping methods. Instead of an astronaut, she now wants to be an aerospace engineer so she can continue her research and make low-energy orbits a reality.

“Nobody is funding low-energy orbits right now, but [scientists] think this is a cool area that hasn’t been figured out yet,” she said. “This is a good time for me to be around.”


UMSF FTW!!!!

I had the opportunity to talk to Erika at the public session for Intel finalists last Sunday and highly doubt that any of her mathematics is in error - she's been doing this for years at a very, very high level, and there were over a dozen experts walking around asking pertinent questions to each finalist. A predecessor to this project was third in the computer science category at Intel's other science fair (ISEF) two years ago; that paper is available here. The difference between the new work and that paper (besides the scope of trajectories analyzed) is the addition of continuous propulsion to the simulation (either solar sail or ion engine), which, for instance, drops the minimum-energy transfer time to Venus from about 100 years to around four.
In any case, I'll try to get Erika to come here and post something if possible; I think those of you with more expertise in this area will be interested in what she has to say.

that paper is available here.

I won't pretend to follow that. But the description of creatively escaping Earth orbit reminds me of ISEE-3/ICE.
