Another canary in the collapsing coalmine.
A paper today in Nature by Borlaff et al. on the impact of ever-increasing numbers of satellites in low-Earth orbit on space telescopes like Hubble, SPHEREx, & CHEOPS today, & Xuntian & ARRAKIHS in the future.
The number of proposed satellites is eye-watering, & the effects on astronomy horrendous – there are wider effects on pollution of the upper atmosphere & safety of key orbital assets as well.
