New Horizons Mission Prepares for Interstellar Space with Solar Wind Forecasting
US · Published Jul 5, 2026
Researchers at the Southwest Research Institute (SwRI) are developing a solar wind forecasting method to predict when NASA's New Horizons spacecraft will encounter the termination shock, the outer boundary of the heliosphere.
This boundary marks the transition between the solar system and interstellar space.

Impact & Risks

The research aims to enhance understanding of the heliosphere's dynamic boundaries, which expand and contract with solar activity. Accurate predictions are crucial for preparing New Horizons to collect valuable data as it approaches the termination shock. This data could provide insights into the interaction between the solar system and the interstellar medium, benefiting future space exploration missions. However, the dynamic nature of the heliosphere poses challenges, as the boundary may shift unpredictably.
