It's becoming increasingly clear to me that Reflect Orbital's fucking stupid giant mirror satellite, with absolutely NOTHING useful to offer, which will cause countless safety issues, ecological disasters, and destroy the night sky, is going to launch.

A bunch of astronomers and I have sent out a fact sheet about them to a bunch of journalists, but very few are going to write about this. So, let me try posting it all here.

Here's what I know about Reflect Orbital and all the downsides:

Reflect Orbital (RO) https://www.reflectorbital.com/ wants customers to pay them to reflect beams of sunlight down from
orbit. This is called “sunlight as a service.”

Their initial plan is for each beam to be several times as bright as the full moon and at least 5 km in diameter on the ground.

Due to the high speed needed to orbit Earth, each satellite will shine on one point for only
a few minutes at most (Reflect Orbital says 4 minutes https://thetundradrums.com/reflect-orbital-order-sunlight/)

@sundogplanets Unbelievable. @pluralistic did say that rent-seekers would try to control solar energy, but this is just beyond ridiculous.

There's an old (1970s?) cartoon (which I can't find right now) of an executive behind his big desk.

"You want oil?" he asks. "We own the oil wells."

"You want coal? We own the coal mines."

"You want nuclear? We own the uranium mines."

"You want solar? We own...er...um...solar doesn't work!"

Did a 1970s Cartoon Ridicule Anti-Solar Power Rhetoric?

"Still too accurate!" said one internet user of the satirical cartoon, which regained prominence online in September 2021.

In 1978 I was eight years old. The ozone hole over the Arctic and CFCs would only go mainstream a few years later. In the UK four star leaded petrol was still normal.

I thought my parents and grandparents saw the worst things ever - WW1 and 2.

They did, but as it turns out, the four horsemen of the apocalypse are still doing a brisk trade.

One day, we will have to pay the piper and our credit line will have vapourised.

That's my entire life, within rounding error of <1%, since it was already well known how much they were letting us down. It's also almost exactly 46 years before I installed my panels, which produced 6MWh in their first year

Interesting that Snopes shows two versions ("Feasible" and "Functional" for the last word) but doesn't comment on the difference, and the "Feasible" version pictured above crops out the attribution
