Predicting the Solar Wind to Map New Horizons' Path to the Heliosphere's Edge

SwRI researchers merged a solar wind forecasting method with heliosphere models to predict where New Horizons will encounter the termination shock, the outer boundary of the heliosphere. They estimate the crossing could occur between 2029 and 2040, with the possibility of multiple crossings as the heliosphere expands and contracts, helping plan future measurements at the solar system's edge.
