Abstract

Astronomy & Astrophysics Physical Sciences Science & Technology
The Cusp Plasma Imaging detector (CuPID) Cube Satellite Observatory is a six-unit Cube Satellite developed to study macroscale properties of dayside magnetopause reconnection. Reconnection will be studied through imaging spatial and temporal ion dispersion signatures in the magnetospheric cusps. As reconnection enables shocked solar wind plasma to enter the cusp, high charge state solar wind ions will charge-exchange with Earth's neutral exosphere. This process generates soft X-rays imaged by the spacecraft. CuPID is in a circular, highly inclined (97.6 degrees), sun-synchronous, low Earth orbit (550 km), where it views upward through the cusp from its low altitude footprint. The mission carries three science instruments, an energetic (>50 keV) radiation detector, a soft X-ray (0.1-2 keV) imager, and a body-mounted magnetometer. The soft X-ray imager employs a novel, wide field-of-view (4.6 degrees) slumped micropore optical element to focus X-rays. The radiation detector uses collimated micro-dosimeters with blocking foils to discriminate particle species. The three-axis magnetometer is part of the attitude determination and control system and has been calibrated to provide scientifically useful data.
