Meetup session on 8/16/2021

We have a meeting on 8/16/2021, rescheduled from the usual time, Second Monday.

We will meet 8/16/21 at 6:30PM, for this one time only. Then, back to 2nd Monday of the month.

Our Mission:
The intent of this aerospace team is to develop open source cislunar and interplanetary trajectories using the NASA GMAT scripting language. This is disruptive technology.

A) Open Source Mission Trajectories
We are applying open source techniques to the development of cislunar and interplanetary trajectory planning and optimization using the NASA GMAT simulator. This simulator simplifies orbital cislunar, translunar, and interplanetary trajectory design and visualization. The results of this research will be made available to small satellite mission planners – students, hobbyists, startups, etc. This is an opportunity for professional as well as amateurs to share ideas and develop skills in the art of trajectory optimization.

B) Open Source Simulator Software
We are upgrading an operational (TRL-9) NASA Open Source Orbital Trajectory Simulation System (GMAT R2020a) to include a Spacecraft Attitude simulation capability. GMAT is written in C++ with links to Python 3. This is an opportunity for professional engineers as well as developers to extend their skill sets to include both aerospace and software engineering as well as Python.

We will be meeting online via ZOOM. MeetUp is not online MeetUp friendly. If you have trouble linking, you can get the Zoom URL by emailing to me here:

Help Wanted:
Aerospace, Mechanical, and Astronautical engineers as well as Python Developers, Digital Artists and Software Engineers, are invited to join us along with other experienced engineers and scientists to build and release a cutting edge aerospace open source software package.

The new simulation system will incrementally create animated visualizations and demo simulations for crowdfunding and user education.

About GMAT:
We have identified an open source orbital trajectory system, the NASA General Mission Analysis Tool (GMAT), for our space flight simulation and visualization. The package (among others) is free, open source, accurate, TRL-9, and tutorial videos are available on YouTube. We will be creating orbital trajectories and adding Python apps which we can discuss in upcoming meetings.

I recommend that interested participants examine the wealth of online documentation. You can also download and install the binaries, and follow the video tutorials. Executable binaries, source and documentation are available from here:

MeetUp Agenda:

• The primary purpose of this meeting shall be to meet and greet our new members, to discuss mission objectives, and how to achieve mutual goals.

• Following introductions, we will discuss the GMAT simulation system.

• We shall discuss coding spacecraft trajectories via GMAT scripts. Available demonstrations will be shown.

• Interested members may form teams to study specific orbits or objectives, e.g. Orbital debris, Asteroid mitigation, Asteroid mining, Small Satellite trajectories.

• We shall discuss implementation of Python plugins for the NASA GMAT software, and new member’s programming interests.

• We also need help in the creation of animations of the proposed mission operations. Specifically we need M.E. expertise to refine CAD models of the spacecraft, and aerospace & astrodynamics expertise to optimize transfer orbits and trajectories, and software expertise in the simulation domain, specifically Python 3.
