NASA's STORIE mission will be mounted on the International Space Station to image Earth's ring current from an inside-out perspective by detecting energetic neutral atoms, helping scientists determine whether ring-current particles come from the solar wind or Earth’s atmosphere, and improve space-weather predictions that affect satellites and power grids during a six-month mission.
NASA's Interstellar Mapping and Acceleration Probe (IMAP) has reached its L1 observation point to begin an all-sky study of the Solar System's outer boundary, using energetic neutral atoms to map the heliopause and track how the edge changes with solar activity—building the first comprehensive view beyond Voyager data.
Scientists have discovered that energetic neutral atoms (ENAs) could be used to investigate the particle acceleration process involved in solar energetic particle (SEP) events such as solar flares and coronal mass ejections (CMEs). ENAs are neutral particles that are not affected by magnetic fields, making them useful for studying these sites remotely. NASA is currently planning an instrument as part of its Interstellar Mapping and Acceleration Probe (IMAP) mission, which will be capable of measuring ENAs originating from the sun.
