The Focusing Optics X-ray Solar Imager (FOXSI) is a sub-orbital rocket project with three successful launches (and gearing up for a fourth in April 2024!) It is the first solar-dedicated instrument to observe hard X-rays using focusing optics. Direct imaging enables the experiment to study solar radiation with enhanced sensitivity and dynamic range, exploring issues of energy release and particle acceleration in the corona-the outermost layer of the Sun.
