abstract:Energetic neutral atom (ENA) imaging, often described as "seeing with atoms", is a technology used to create global images of otherwise invisible phenomena in the magnetospheres of planets and at the boundary of the heliosphere - the far-flung outer edge of the solar system.
Although the probe would carry no cameras in the classic sense, its onboard instruments would include a low-energy charged particle experiment, a magnetometer, a cosmic ray detector, and an energeticneutralatom detector.
