Wasn’t this a plot point of Who Shot Mr Burns?
Sometimes you need to think about if you should, not if you can. Nonsense.
Humans. Who else would have groups talking about sending up a filter to weaken the sun and another group working to shine MORE sun on the earth.
I don’t get why we would want to do this.
This is such a vastly idiotic idea. How/why is anyone seriously thinking about this? The atmosphere alone will distort and absorb whatever energy beam might be sent from this mirror. Ridiculous.
Russia tried this in the 90s called Znamya to mixed results. More of a test project that more or less stalled.
Let them waste their money. Sometimes even idiotic ideas can bring some useful findings we can use in less idiotic projects.
This would be way more useful to direct light to Mars or another planet to increase agriculture viability if we ever managed to get a dome there. Not make things worse here.
> The first satellite, named Eärendil-1—after the Old English word for morning star—will shed only as much light as a full moon, across a 6,000-acre area, or about the size of an airport.
I’m sure Stephen Colbert will appear to make a more precise correction, but Time got this wrong. „Eärendil“ is from Tolkien. He was the half-elven seafarer who carried the morning star. Tolkien took inspiration for the name from the Old English „Ēarendel“ which derives from Norse „Aurvandill“ (https://en.wikipedia.org/wiki/Aurvandill).
So if the satellite was named after the Old English word it would be Ēarendel. If it’s spelled Eärendil it’s taken from Tolkien.
So, this mirror will not turn night into day. Its maximum brightness is 1/400,000th the brightness of the noon sun.

There’s an argument to be made for lighting up a solar farm at night, however, investing the money in energy storage probably makes more sense.
Also, if you’re worried about messing with human circadian rhythms, you should look into a Chinese proposal to illuminate cities at night for crime prevention.
Any chance that this could accidentally and uncontrollably become a hyper-focused sunbeam which scours every inch of the surface unlucky enough to fall within its gaze?
Because I’ve got that on my 2026 Bingo card..
Why is this even needed. Like why?
This title reads like a Starship Trooper propaganda ad, and yes, I would like to know more.
Now they charge a subscription to have a night time💀
I’m sorry if this is a stupid question, but what effects would this have on the ozone layer?
Unrelated but hey folks open invitation to join my new amateur rocketry club, “Target Practice”
