algorithm is used to traverse the search space and more carefully optimize the solutions

\subsection{Trajectory Composition}
Discuss briefly the nomenclature used in defining these trajectories. Currently this isn't
``baked in'' to the code, so I have some freedom to adopt Englander's notation or use my own
(since my intended use case is a little simpler).
\section{Trajectory Composition}
\subsection{Inner Loop Implementation}
Give a better overview of the inner loop specifically. Probably this section will have a more
in-depth flowchart.
In this thesis, a specific nomenclature will be adopted to define the stages of an
interplanetary mission in order to standardize the discussion about which aspects of the
software affect which phases of the mission.
\subsubsection{LaGuerre-Conway Kepler Solver}
Overall, a mission is considered to be the entire overall trajectory. In the context of
this software procedure, a mission is taken to always begin at the Earth, with some
initial launch C3 intended to be provided by an external launch vehicle. This C3 is not
fully specified by the mission designer, but instead is optimized as a part of the
overall cost function (and normalized by a designer-specified maximum allowable value).
This overall mission can then be broken down into a variable number of ``phases''
defined as beginning at one planetary body with some excess hyperbolic velocity and
ending at another. The first phase of the mission is from the Earth to the first flyby
planet. The final phase is from the last flyby planet to the planet of interest.
Each of these phases are then connected by a flyby event at the boundary. Each flyby
event must satisfy the following conditions:
\begin{enumerate}
\item The planet at the end of one phase must match the planet at the beginning of
the next phase.
\item The magnitude of the excess hyperbolic velocity coming into the planet (at the
end of the previous phase) must equal the magnitude of the excess hyperbolic
velocity leaving the planet (at the beginning of the next phase).
\item The flyby ``turning angle'' must be such that the craft maintains a safe
minimum altitude above the surface or atmosphere of the flyby planet.
\end{enumerate}
These conditions then effectively stitch the separate mission phases into a single
coherent mission, allowing for the optimization of both individual phases and the entire
mission as a whole. This nomenclature is similar to the nomenclature adopted by Jacob
Englander in his Hybrid Optimal Control Problem paper, but does not allow for missions
with multiple targets, simplifying the optimization.
\section{Inner Loop Implementation}
The optimization routine can be reasonable separated into two separate ``loops'' wherein
the first loop is used, given an initial guess, to find valid trajectories within the
region of the initial guess and submit the best. The outer loop is then used to traverse
the search space and supply the initial loop with a number of well chosen initial
guesses.
Figure~\ref{nlp} provides an overview of the process of breaking a mission guess down
into an NLP, but there are essentially three primary routines involved in the inner
loop. A given state is propagated forward using the LaGuerre-Conway Kepler solution
algorithm, which itself is used to generate powered trajectory arcs via the
Sims-Flanagan transcribed propagator. Finally, these powered arcs are connected via a
multiple-shooting non-linear optimization problem. The trajectories describing each
phase complete one ``Mission Guess'' which is fed to the non-linear solver to generate
one valid trajectory within the vicinity of the original Mission Guess.
\begin{figure}

\includegraphics[width=\textwidth]{LaTeX/flowcharts/nlp}
\caption{A flowchart of the Non-Linear Problem Solving Formulation}

\end{figure}
\subsection{LaGuerre-Conway Kepler Solver}
Discuss how the LaGuerre-Conway algorithm is used in the code to provide a fundamental
``natural trajectory'' between two quantized, but not necessarily close points. Mention
validation.
\subsubsection{Sims-Flanagan Propagator}
\subsection{Sims-Flanagan Propagator}
Discuss how this algorithm can then be expanded by using SFT to propagate any number of
low-thrust steps over a specific arc. Mention validation. Here I can also mention the ``Sc''
object and talk about how those parameters were chosen and effected the propagator.
\subsubsection{Non-Linear Problem Solver}
\subsection{Non-Linear Problem Solver}
Mention the package being used to solve NLPs and how it works, highlighting the trust region
method used and error-handling. Mention validation.

simple to lend itself to one.

\subsection{Monotonic Basin Hopping}

each of the decisions, similar to Englander's paper on this.

Give some real-world context for the mass-use, time-of-flight, etc.
\subsubsection{Comparison to Impulsive Trajectories}
\subsection{Comparison to Impulsive Trajectories}
I may also remove this section. I could do a quick comparison (using porkchop plots) to
similar impulsive trajectories. Honestly, this is a lot of work for very little gain,
though, so probably the first place to chop if needed.

Dr. Scheeres,
I'm currently working on finishing up my Master's Thesis. The topic will be a routine for optimizing
Interplanetary Low-Thrust Trajectories, combining approaches for flyby optimization and low-thrust
trajectory arc optimization. I think that your research interests would make you an ideal fit for a
place on my committee, so I would like to ask if you have any availability to be on my committee
this semester? Currently, I am targeting finish up sometime around March 12th, so it would probably
be a defense in late March or early April, but I have a little room for flexibility if that doesn't
work.
If you think you may be able to sit on my committee then just let me know and I can begin the
process of determining everyone's availabilities and finding the most appropriate defense date.
Thanks!
Connor Johnstone
