ACE satellite performs measurements over a wide range of energy and nuclear mass, under all solar wind flow conditions and during both large and small particle events including solar flares. It provides near-real-time solar wind information over short time periods. ACE can also provide an advance warning (up to 60 minutes) of geomagnetic storms that can overload power grids, disrupt communications on Earth, and present a hazard to astronauts.
