Artists Conception of FASR
The Frequency Agile Solar Radiotelescope (FASR) is an ultra-wideband radio array designed to image the Sun and its atmosphere over a frequency range of 50 MHz to more than 20 GHz, corresponding to wavelengths of <1.5 cm to 6 m. Radio emission over this frequency range originates from the middle-chromosphere to the outer corona. FASR will therefore image the Sun's atmosphere in 3D, and it will do so at least once overy second. This innovative approach - dynamic, broadband, imaging spectroscopy at radio wavelengths - enables unique measurements of coronal magnetic fields, magnetic energy release, particle acceleration and transport, plasma heating, shock formation, and drivers of space weather.

FASR was ranked as a priority project by the Solar and Space Physics Survey Committee decadal review and by the Astronomy and Astrophysics Survey Committee decadal review.
