## Executive Summary
NASA’s New Horizons spacecraft has detected an interstellar slowdown caused by atomic drag at the edge of the solar system.

## Intelligence Brief
NASA&amp;#039;s New Horizons mission is examining solar winds at the solar system&amp;#039;s edge. Data indicates a solar wind slowdown occurring as interstellar atoms create drag on the system.


Coverage from Phys.org, Gizmodo, and Open Access Government emphasizes the discovery of this hidden slowdown. EurekAlert! reports that solar wind forecasting will be used to help define the boundaries of the heliosphere.


Future developments involve using these solar wind forecasts to further clarify the specific boundaries of the heliosphere.

## Verified Facts & Key Claims
### What is causing the solar wind slowdown?
According to Phys.org, the slowdown is caused by interstellar atoms adding drag.

### Which spacecraft is providing this data?
The data is being provided by NASA's New Horizons.

### What is the goal of the solar wind forecasting mentioned in the reports?
The forecasting will help define the boundaries of the heliosphere.
