SpaceX filed an application with the US Federal Communications Commission for a megaconstellation of up to one million #satellites to power data centres in #space.
The proposal envisions satellites operating between 500 and 2,000 kilometres in low Earth #orbit. Some of the orbits are designed for near-constant exposure to sunlight.
The approval process for these satellites focuses almost entirely on the limited technical info companies have to submit to regulators.
Cultural, spiritual, and most #environmental impacts aren’t taken into account – but they should be.
At this scale of growth, the night #sky will change permanently and globally for generations to come.
In 2021, astronomers estimated that in less than a decade, 1 in every 15 points of light in the night sky would be a moving satellite. That estimate only included the 65 000 #megaconstellation satellites proposed at the time.
Once deployed at a scale of millions, the impacts on the night sky may not be easily reversed.

She's been doing stellar work in bringing this stuff into light (no pun intended) for a while now.

@nihkeys @mustapipa I'm a co-author on this article
Also @mustapipa was a co-author on a research paper I led many years ago! -

At 1M objects at proposed altitudes and assuming equidistant, uniformly filled shell deployment, mean separation between them is only 100 km (assuming tighter orbital parameters only makes this separation smaller still). This might sound plenty but consider average orbital speed of ~7.25 km/s at proposed altitude range and they only get on average ~14 seconds reaction time to adjust their vectors for collision avoidance. Basically, one unfortunate collision with the tiniest of space debris, or micrometeoroids, or a complex CME and the Earth gets evanescent rings of fine metallic powder and one hell of a light show
