SUMMARY: NASA has chosen to fund a new spacecraft, called the Interstellar Boundary Explorer (IBEX), to study the edge of the Solar System, where the solar wind from the Sun interacts with interstellar particles. IBEX will launch in 2008, and take a highly elliptical orbit that keeps it away from the influence of the Earth's magnetosphere. It's equipped with two neutral atom imagers designed to spot interstellar particles as they interact with the outgoing solar wind. IBEX will also study galactic cosmic rays that pose a radiation risk to space explorers.
