IBEX Mission

In its elliptical orbit around the Earth, the IBEX spacecraft is pointed towards the

sun, and spins continuously. Two narrow angle image sensors (IBEX-Hi and IBEX-

Lo) are positioned perpendicular to the spin axis. These special imagers detect

neutral atoms from the solar system’s outer edge, enabling scientists to map the

boundary between our Solar System and interstellar space.
