NASA hopes to launch its newest astronomy satellite, the Interstellar Boundary Explorer (IBEX), soon. The goal of this mission is to study the "termination shock" formed when the Solar wind is decelerated by the "interstellar medium" (diffuse hydrogen gas, for the most part) that fills the Milky Way - a boundary recently crossed by both Voyager missions.
