The Solar Flare Dynamics Imager (SolFDI) is a very low-cost flare mission proposed for this upcoming solar maximum. It is based on a small solar EUV telescope/spectrograph for Spartan Lite, NASA's new ejectable hitchhiker spacecraft.

The experiment's main scientific objective is to investigate the spatial, temporal, and velocity structure of the upflowing hot plasma frequently observed in soft X-ray lines during solar flares. Past observations were spatially unresolved, and the nature of these plasma flows, and their relationship with the impulsive phase flare energy release are not well understood. The second objective is to image the spatial and velocity structure of eruptive flares. Such observations can ultimately reveal the true three-dimensional geometry of the eruptive component of the flare.

The Solar Flare Dynamics Imager will observe flares in a few selected extreme ultraviolet lines, including a high temperature Fe XXIV line. The instrument uses normal incidence multilayer coated optics to provide simultaneous imaging and spectroscopy in these lines with good spatial, spectral, and temporal resolution. The instrument is designed to fit within the envelope of the Spartan Lite ejectable hitchhiker spacecraft. Spartan Lite is smaller, and costs a fraction of a SMEX spacecraft. But if launched into the upcoming solar maximum, its 6-12 month mission duration would be sufficient to achieve SolFDI's scientific objectives.
