This is a fantastic video explaining orbital dynamics and the resulting economics, and security considerations of cislunar space. Well worth the 8.5 minutes to watch. youtu.be/kdpOdSMzXTA?is=By6z…

Thanks for the hint! Very good one, with excellent animations. And let's not forget about BLT (Ballistic Lunar Transfer) advancedspace.com/wp-content…

Nice video, cool to see someone finding a use for the two stable Lagrange points at L4 and L5

Thank you for mentioning this. I had missed it entirely.

Orbital guard referenced...? No space navy, rescue and traffic control require a space coastguard.

Orbital and Cis-lunar war of attrition is incoming.

This is a good one. Simple enough and understandable

Exciting future. This is the kind of stuff that reminds us to think and dream bigger.

TBH, the torus shape for cislunar isn't a definition I've seen before, although it is something that needs a name, and that name fits it perfectly.

Oh... 😳 this is starting to feel very very real guys, is not sci-fi anymore(!) We are in the future, and i mean The Future.
