OK I am genuinely nervous about this but also excited. Just launched ep1 of my new podcast "Space Citizens" (yes the same name as my Substack newsletter). It starts with a bit of a rant, will include some awesome guests, and will probably be peppered with more rants. open.spotify.com/episode/6a4C...

Last week's Space Citizens substack was about the Artemis Accords. Because they turned 5 years old and now have 60 signatories. I can't help still being cynical, but maybe I have to resign to the fact that this is the guiding document for lunar activities. spacecitizens.substack.com/p/happy-birt...
Happy Birthday Artemis Accords
Am I still allowed to be skeptical?

As is often the case with international conferences, here at #APRSAF-31 in Cebu, Philippines, we are inside an expensive resort all day. But I walk from my accommodation to the venue past those Philipinos who built and work in the resorts, and see the other side of the coin

Crisis as Catalyst: Past, Present, and Future of International Law

This is autobiographical. But it's also an invitation to anyone who's ever dreamed of a career in space and thought it wasn't possible. My journey to space (as a space lawyer. Caveat: never actually been to space.)

Literally brought me to tears. Ziptied kids together, put guns in the face of US citizens (no coincidence that these are black citizens) and explicitly dehumanise them, threaten them, attack their homes. I know this is going down, but to hear these eyewitness accounts made me cry.
