The CuPID (Cusp Plasma Imaging Detector) Cubesat Observatory is designed to test competing models of solar wind-magnetosphere coupling. The 6U spacecraft is roughly the size of a toaster oven and will carry a wide field-of-view soft X-ray telescope, the first of its kind to be placed into orbit. In orbit the spacecraft will measure soft X-rays emitted from the process of charge-exchange when plasma from the solar wind collides with neutral atoms in the Earth’s distant atmosphere. The spatial and temporal patterns of X-ray images will be used to address scientific questions. The project is a collaboration between Boston University, NASA Goddard Space Flight Center, Johns Hopkins University, Merrimack College, Aerospace Corporation, Drexel University, and the University of Alaska, Fairbanks.
