those people does not understand the beauty of natural meteor shower
-
They would be less like meteors and more like tracer bullets. Meteors get their light from the instant compression of air as the object collides with the mesosphere at an average of 20 km/s. The pellet would only reach a speed of 2.7 km/s max (actually less, considering that gravity is weaker at 450 km and the upper layers of the atmosphere would slow its descent). Therefore, the light would have to come from combustion alone, like the chemicals in a tracer bullet. Same effect, but not the same.

It's probably just magnesium or something similar tbqhfam
-
just like the "real" meteor showers. dont believe what they feed you folks
-
I thought of this a while back, even the chemical/elements multi color part. When I thought of it I thought it would be far more complicated though. The idea is easy to come up with but implementing it is far more difficult... so props to the people making it happen.

ALE: "they're taking the piss"
-
"All they need to pull it off is a tiny satellite, a secret formulae and a rocket."
You're not allowed to end a sentence that starts 'All they need' like that. -
what about all the garbage going into low orbit? what about all the pollution of the stratosphere?
-
great..... sci show has sold out to big meteor. 😉
-
This was Vandel Savage's Master Weapon in Justice league.
-
no just no, stop messing with nature and dumping chemicals into the atmosphere, like really? as if our atmosphere wasn't polluted enough already? sigh...
-
If they keep cutting space funding, they'll get a bunch of meteors for free!
-
what makes them beautiful its not knowing or at least not planning a meteor shower, otherwise its just burning stuff

Just tell the meteor it smells.

"let's put a whole bunch of chemicals in the mesosphere where it's really sensitive to small chemical changes. We don't know or care how it'll affect the dynamics there because it hasn't been studied that well, but hey scientists that's what we can help you with huh"
Just a scam with the earth's climate on the table. -
"Hey we've got this atmospheric layer that is very sensitive to the addition of greenhouse gases...lets burn some stuff up in it!" xD
-
Love the show but this is a very bad and wasteful idea.
-
So we're going to drop tiny synthetic pellets into a sensitive part of the atmosphere.... To see what happens? clap That's some Nobel Prize thinking.

In order for scientists to be able to make use of any of the data they obtained, they'd need to know the chemical make-up of the particles. And if the company wishes to keep that recipe proprietary, that will be difficult to come by, to say the least.
