Interstellar Boundary Explorer is a NASA satellite in Earth orbit that uses energetic neutral atoms (ENAs) to image the interaction region between the Solar System and interstellar space. The mission is part of NASA's Small Explorer program and was launched with a Pegasus-XL launch vehicle on 19 October 2008.

Energetic Neutral Atom (ENA) imaging is a technology used to create global images of otherwise invisible phenomena in the magnetospheres of planets and throughout the heliosphere.
A hot plasma ion 'steals' charge from a cold neutral atom to become an Energetic Neutral Atom (ENA)

The ENA leaves the charge exchange in a straight line with the velocity of the original plasma ion.
