Doing something like that at planetary scale is science fiction anyway even if we did have the tech to do it.
Talking to computers and expecting computers to answer coherent English was science fiction 4 years ago. Don’t lose faith
All 12 moonwalkers had "lunar hay fever" from dust smelling like gunpowder (2018)

Re: All 12 moonwalkers had "lunar hay fever" from dust smelling like gunpowder (2018)
#212I recall an article from a long time ago that basically said “astronauts report” the moon smells like spent gunpowder and outer space smell like… I think it was ozone. What they were actually reporting was the smell of the airlocks after they returned from their excursions. The moon has no atmosphere, so it has been accumulating dust from billions of years of asteroid impacts that have never come in contact with oxyg…
i'm wondering how do people even know what ozone smells like?
Ever been next to an electric arc discharging? The odour you can smell is Ozone.

#213This sounds as if walking on the moon led to some symptoms. But if you know Chris Hadfield, he said "space has a rusty burn smell" even elsewhere. How can they conclude that moonwalking specifically led to what was described? The article has "The toxic side of the Moon", but IMO it would be more reasonable to assume that space in general is toxic, not "only" the moon. It also means that the space suits are not well-equipped - people in 50 years from now will shake their heads about that, how naive we may have been.

Well, oxygen _is_ poison. It's eager to react (sometimes violently) with almost everything. It rusts and oxidates perfect shiny metals and silicon making everything an oxide!
No. "Poison" refers to a substance toxic to humans, but we can be exposed to pure oxygen and breath it very fine. But yes, oxygen is dangerous .
"Poison" can also refer to a substance toxic to other animals. We say that chocolate is poisonous to dogs for instance. And a good fraction of Earth's biosphere was killed off by oxygen poisoning in the first of Earth's great mass extinctions.
Also, the dose makes the poison and excess oxygen actually can poison humans. Deep sea divers have to worry about excess oxygen inducing seizures if they mess up their breathing gasses enough. And even 100% oxygen at regular pressure will slowly damage the lungs, something ICUs have to worry about.
Nick Lane had a great book about oxygen, Oxygen, which maybe isn't as good as his book about mitochondria but is well worth reading.

Stars kinda famously fuse elements up to iron as part of normal operations. And even if you exclude that, the entire solar system is leftovers from a previous star - all that is inside our current star too. Sure, much of it isn't at the surface, but there's not much of a reason to expect that literally zero of it randomly floats up among the lighter elements. Have a reference tho: https://en.wikipedia.org/wiki/Solar_…
> our current star Looking forward to seeing the next one!
We first need to get rid of the current one in a few billion years. That won't end well for Earth, though.

#217As a huge space nerd, I would like to point out that space, and other planetary bodies appear to really suck. It seems to be under-reported that the Earth is pretty nice.
Our Earth is like a blue angel in the solar system.

Sadly, it's populated.
My friend, misanthropy is giving last year energy. Don't get so down. In other under-reported news: until the Earth reaches 100% de-population, it can in-fact get worse. Therefore, it's currently not that bad! Let's take a moment to appreciate that we live on a populated planetary body. The Peter Thiel has not yet achieved its ultimate goal. Good times.

Have you read the news lately?

#219Unbelievable, billions spent on sending few to moon while millions are dying homeless here
Unbelievable, literally trillions upon trillions spent on all other kind of shit like warfare and utter corruption. And some people just can't get over that people fifty years ago spent a minuscule fraction of that to go to the moon.

It's the smell of photocopiers or laser printers operating.
