Southwest Research Institute scientists are using a solar wind forecasting method along with analytic and numerical heliosphere models to determine the location of the first plasma boundary of the outer heliosphere, as NASA’s New Horizons spacecraft approaches this area.

Southwest Research Institute (SwRI) scientists are using a solar wind forecasting method combined with analytic and numerical heliosphere models to find out where the first plasma boundary of the outer heliosphere lies as NASA’s New Horizons spacecraft hurtles toward this mysterious region of space.
