An animation showing the position of the IBEX spacecraft and its field of view superimposed on a diagram of the heliosphere. The cones that extend from the IBEX spacecraft represent the field of view of the IBEX-Hi and IBEX-Lo Sensors as the Earth travels around the Sun each year. The black lines show how the data from the space craft is mapped to a two dimensional diagram over the course of a year. The data in the diagram is simulated data and the drawing is not to scale.

An animation showing the position of the IBEX spacecraft and its field of view superimposed on a diagram of the heliosphere. The cones that extend from the IBEX spacecraft represent the field of view of the IBEX-Hi and IBEX-Lo Sensors as the spacecraft spins on its axis. The black lines show how the data from the space craft is mapped to a two dimensional diagram as the spacecraft spins four times a minute. The data in the diagram is simulated data and the drawing is not to scale. Credit: The IBEX Team/Southwest Research Institute
