Nested inertial frames—Earth, Sun, Galaxy—can exchange angular momentum. IRFIH derives a coupling term matching mm/s fly-by Δv still unexplained by GR.

Netflix's '3 Body Problem' Is Unrealistic
The variable sun intensity shown in the (very entertaining) Netflix series is just not possible. Either the planet is close to the 2 stars and gets thrown out of the system or it's far away and the light intensity will hardly vary. #Netflix #Astrodynamics

UNCONTROLLED REENTRIES CAN BECOME A SERIOUS PROBLEM for airspace. In a recent work in #Astrodynamics we already predicted that these reentries will become far more frequent in the future:

A continuing problem in modeling languages like #UML or #SysML2 is that they don't allow for the fact that attributes can be functions. An example would be the density of a solid object, which is a function of position. Example: In #astrodynamics, to model the density of the atmosphere.

The #books on my desk reflect accurately what makes my busy those days. It's all about #space, #chaos and #astrodynamics 🛰️🦋

Certainly! Here's an alt text description for the figure: "Graph depicting satellite lifetime versus orbital altitude for low-altitude Earth orbits. The x-axis represents mission duration in hours, ranging logarithmically from 1 hour to 100,000 hours (approximately 3 years). The y-axis represents circular orbit altitude in nautical miles, ranging from 10 to 50,000 miles. The chart includes several shaded regions: one labeled 'Safe Operating Region Except for Unexpected Events,' another marked as 'Astronaut Radiation Tolerance under a Minimum of 4 Pounds per Square Foot of Shielding,' and a region indicating 'Orbital Flight Duration Limitation due to Atmospheric Drag Without Propulsion.' Additional labels include 'Expected Limit for Meteoroid Puncture of Medium-Sized Manned Space Stations' and '25% Reduction in Solar Cell Output.' These zones delineate operational constraints and risks at various altitudes and durations."

This diagram from Bate, Mueller, White's astrodynamics (and taken from 1965 Space Planner's Guide) shows why Earth-orbital altitudes are confined to a very narrow range. Going above around 560 km is human experimentation on radiation effects. #Astrodynamics

Can't wait to teach my new #course on #astrodynamics next semester at #UNamur! Looking forward to train and educate our students on #SpaceDebris, #SustainableSpace and other exciting #challenges. Back to basics and the two-body problem for now 🛰️

Folks, what would be your go to reference/book for a course on modern #astrodynamics?

poliastro: a Python library for interactive astrodynamics - SciPy Proceedings Space is more popular than ever, with the growing public awareness of interplanetary scientific missions, as well as the increasingly large number of satellite companies planning to deploy satellite c...

I indulged myself re-reading my finest ever piece of writing: the poliastro 2022 paper for #SciPyUS2022

Now re-rendered with @curvenote.com to look extra cool 🔥

I'm so damn proud of this work. I miss Astrodynamics and applied math so much 💔

#introduction

Hi! 👋 I'm Isaac, Mathematician and Data Scientist from Spain, currenly doing a PhD in #astrodynamics and #AI

Huge nerd, I'll mostly talk about #technology #science #gamedev and #books

I also like doing cool math art with processing, so I may post some of those from time to time...

Where my #Fortran and #Astrodynamics people at?

Modeling planetary orbits in 2D for my stock market game. Works great, even has velocity. Hoping to get ideal Hohmann transfer paths rendered out too. #astrodynamics #godot #gamedev

Some more screenshots of the tutorial and missions I've been designing with it! 🛰️📡 #FreeFlyer #astrodynamics #satellites
