NASA does make its own clouds… why does it do it and is it dangerous?

It’s a common experience, but intriguing to say the least. In early November, NASA manufactured artificial clouds above the Norwegian sky. A process that is not harmful to the environment. The objective is to advance science, while observing movements in the upper atmosphere, where these vapors are released. It would therefore be counterproductive for chemical compounds to disrupt the environment.

Concretely, how does this experience take place? In reality, NASA uses probes, equipped with canisters containing different chemical compounds, such as tri-methylaluminum (TMA), which produce luminescent vapors, then acting as tracers.

The artificial clouds created by NASA fly between 80 and 400 kilometers in altitude. As the Actu.fr site explains, they are colored, with tracer materials (barium, lithium, aluminum, etc.), so that scientists can follow their movements more easily. These are components that we find in fireworks, and which are also released in larger quantities at these times than for this scientific experiment.

“Scientists seek to understand these movements because they represent fundamental knowledge of the Earth’s near-space environment,” NASA indicates to the media. And added: “The movement of neutral and ionized gases reveals how mass and energy are transported from one region to another. These movements (…)
