Current rules are that the risk to human life can't exceed 1 in 10,000, although this doesn't extend to longer term impacts like ozone depletion or climate warming. Unfortunately with increasing launches and re-entries this sort of thing will only get worse...

I'm no fan of Ratcliffe or his tax situation, but doesn't the £200 million relate to rail infrastructure for the wider site and not the stadium, which would typically be paid for by the government? Genuinely asking as I'm not an expert.

Hi Katie, we published a study about this at UCL last year with @planet4589.bsky.social www.nature.com/articles/s41... The anthropogenic influx of aluminium from the space industry is already larger than the natural amount from dust and meteors.

The thing about letting things burn up in the atmosphere is that they're still *there* -- just in gas form instead of solid. So like sure it doesn't hit you on the head (good!) but it might mess with the chemistry of the atmosphere (real bad!) and/or become stuff that you breathe (not great either!)
“The demise of just one Gen1 Starlink satellite produces about 30 kilograms (66 pounds) of aluminum oxide, a compound that eats away at the ozone layer. A new study finds these oxides have increased 8-fold between 2016 and 2022, and the recent surge is increasing the pollution even more.”

This is so cool! I'm trying to get a similar visualization for a website I'm building, what did you use to draw the globe and the arcs?
