Note: This post is adapted from a journal paper I was a co-author on (my other Co-Authors, particularly Jared Sikes and James Pezent, deserve far more credit than I for both the GTOC solution and the paper), which was accepted to Acta Astronautica in Summ

I just got access to the DALL-E beta, and I basically spent a night with some friends exploring different prompts. Here are some of my favorites. Note this will be an image-heavy post and may take a moment to load. What is DALL-E DALL-E is a transformer m

I go over 5 astrodynamics textbooks I have on my shelf.

Pop Quiz! What's 1 + (1e-16) -1? That's easy you might say, it's just 1e-16 We can check that with our favorite calculator (in my case that's a TI-84 that I've had for way too long, but its easier to take screenshots of python) and we get Wait, that's not

Note: These ideas are worth what you pay for them. GPT-3 Enabled Plagarism Every few months there's a new set of handwringing over plagiarism enabled by GPT-3. It's been two years so that handwringing has even reached philosophy departments. Sarcastically

Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment NASA's CAPSTONE mission is a whole deep-space tech demonstrator packed into approximately 730 cubed inches. Even its acronym, CAPSTONE (Cislunar Autonomous Positioning

In an old post we went over the finite difference method, where we approximated the derivative of a function by sampling the function at multiple specific points, and then, as the name implies, taking the difference between these points. Finite differenci

Earlier this year I (successfully!) defended my dissertation titled "Design of Missed Thrust Resilient Trajectories Using Expected Thrust Fraction" and have now obtained my Doctorate of Philosophy. As, could have been expected, my dissertation was on Expe

Stuff Happens… In the tail end of 2021, SpaceX launched a commercial resupply mission to the ISS. That mission used Booster B1069, which landed successfully on the drone ship. Unfortunately, by the time it returned to port, something had happened, damagin
