Io Volcano Observer (IVO) is a proposed unmanned spacecraft that, if approved and launched, would orbit Jupiter and perform at least seven flybys of Jupiter's moon Io. IVO has been proposed to NASA by the University of Arizona as both a science and engineering mission, originally as part of NASA's Discovery & Scout Mission Capability Expansion (DSMCE) concept-study program. Currently, the mission is a possible proposal to be submitted for NASA's Discovery program. As such, IVO has not been funded and it is still in its conceptual phase; if selected, its intended launch window would be in January 2015.
