NASA Creates Clouds Globally: Discover the Reasons

In early November, NASA generated artificial clouds over Norway for scientific purposes, posing no danger. This wasn't the space agency's first such endeavor. What will their next experiment be?

Norwegian Skies Dotted with Artificial Clouds

The National Aeronautics and Space Administration (NASA) has recently created clouds above Norway, a common practice for the space agency aimed at enhancing scientific understanding.

An Environmentally Safe Phenomenon

To generate these clouds, NASA employs probes loaded with various chemicals, including Tri-methyl aluminum (TMA), which produces a type of luminescence in this “artificial vapor”. According to NASA, these substances are “absolutely harmless to the environment or life on Earth“.

“The vapors used as tracers are metals more commonly found in typical fireworks. Tracer materials, such as barium, lithium, and aluminum compounds, are used to color fireworks and provide intense light displays. A typical tracer payload releases about one pound (0.4 kg) of material. In comparison, a standard firework releases several times this amount and is much closer to the ground.”

Scientific Goal: Understanding Atmospheric Movements

The creation of these artificial clouds serves a specific purpose: to study certain movements in the upper atmosphere. Similar to dye being added to water to observe current directions, these colored clouds allow scientists to precisely track atmospheric movements.

NASA explains: “Scientists seek to understand these movements as they provide fundamental knowledge about Earth’s near-space environment. The movement of neutral and ionized gases reveals how mass and energy are transported from one region to another, and these movements also respond to changes in solar activity.”

A Common Practice for NASA

Creating artificial clouds is a routine practice for NASA, conducted globally based on ongoing research needs. Currently, no launches are planned from or above France.
