Nick Campion talks about how SpaceX has powerful "sustainable" imagery + "helpful" narrative, but we're actually just re-doing violent colonization in space. How do we fight this?

We don't need to argue that there aren't benefits (there definitely are). SpaceX is essentially "greenwashing" the pollution they are producing - need to calculate TOTAL cost of satellite constellations (enviro, culture, human). "Our Space: not yours to destroy." Nature does not end as we leave the Earth.

Aparna Venkatesan: "I thank my students and my children for holding me accountable to the future" wow I wish we could all have that mentality! Highlighting the voyage of the Hokule`a using traditional Polynesian celestial navigation - tiny ship just returned to San Francisco.

We humans have an ancient relationship with the night sky, and we need to reclaim this before it's lost - the sky is currently being colonized by bright satellites.

Points out that there's already a cost to satellites in research astronomy: brighter skies mean we can do less science with the same amount of taxpayer $ due to the actions of for-profit private companies. This hugely affects traditional stargazing, highlights effects on Wayfinding: dawn or dusk are when satellite light pollution is worst, when observations are most important for navigation.

It is not inevitable yet how the story in orbit will unfold. Inevitability becomes the justification for moving forward, but it's not inevitable. The skies belong to all of us, not just humans, need to honour that through advocacy.
