## Executive Summary
Researchers are developing a solar wind forecasting method as NASA's New Horizons approaches the edge of the solar system.

## Intelligence Brief
NASA's New Horizons spacecraft is nearing interstellar space. In anticipation of this transition, researchers are creating a new method to forecast solar winds, as astronomers have discovered why these winds gradually slow down while traveling away from the solar system.


Coverage from Universe Today, Newswav, IFLScience, and The Brighter Side of News emphasizes the potential for New Horizons to reach this frontier sooner than previously expected. The reporting focuses on the intersection of new forecasting tools and the observed deceleration of solar winds.


Future developments depend on the application of this new research to determine exactly when New Horizons will leave the solar system.

## Verified Facts & Key Claims
