This week in 2012, the Focusing Optics X-ray Solar Imager was launched aboard a sounding rocket from White Sands, New Mexico, to study smaller, barely visible events of the Sun called nanoflares. FOXSI made use of a telescope that was able to focus on incoming high-energy X-rays from the Sun in a way that was not previously possible for solar observations. Here, the FOXSI instrument is shown composed of seven grazing-incidence telescope modules, each with nested shells. NASA’s Marshall Space Flight Center developed the optics for FOXSI. The NASA History Program is responsible for generating, disseminating and preserving NASA’s remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological and scientific aspects of NASA’s activities in aeronautics and space.
