Splinter is your home for news and opinions that challenge power in our political and economic system that's becoming more unhinged each and every day.
SpaceX has been receptive to design changes to starlink in the past to minimize impact, like decreasing reflectivity and reflection angles for astronomers. They might be receptive to moving to different alloy for the body construction.
Magnesium comes to mind that would be light but expensive. Steel alloys might be cheap and heavy options for later when starship is operational. Would those have similar effects on ozone, or is it only the aluminum oxides? Carbon fiber also looks promising. It could be pretty cheap and light if you can keep it planar rather than custom formed. Someone had mentioned wood in a different thread, but I’m uncertain if that’d work because of off gassing.

Japan I think launched a wooden one, will see what they find out
