The Focusing Optics X-ray Solar Imager (FOXSI) rocket project is a collaboration between UMN, UCB, NASA/Marshall, NASA/Goddard, JAXA/ISAS, and the National Astronomical Observatory of Japan. This experiment studies solar radiation by exploring issues of energy release and particle acceleration in the corona—the outermost layer of the Sun. The rocket observes and collects x-ray data throughout its brief six to seven-minute flight by targeting active regions, small solar flares, and the quiet Sun. This data provides our teams with information about the behavior of high-energy electrons (small, negatively charged particles) as they travel through the corona. FOXSI is the first solar mission to use direct focusing optics in such a high energy range, rather than the indirect imaging methods of the past. The rocket’s third launch is scheduled for August 24, 2018. For a more in-depth look at FOXSI-3, please visit our Upcoming Launch page.
