Two Wide-Angle Imaging Neutral-Atom Spectrometers (TWINS)
TWINS stereoscopically images the magnetosphere and the charge exchange energetic neutral atoms (ENAs) over a broad energy range (~1-100 keV) by using two identical instruments on two widely spaced high-altitude, high-inclination spacecraft.
The Two Wide-angle Imaging Neutral-atom Spectrometers (TWINS) mission provides a new capability for stereoscopically imaging the magnetosphere. By imaging the charge exchange neutral atoms over a broad energy range (~1-100 keV) using two identical instruments on two widely spaced high-altitude, high-inclination spacecraft, TWINS will enable the 3-dimensional visualization and the resolution of large scale structures and dynamics within the magnetosphere for the first time. In contrast to traditional space experiments, which make measurements at only one point in space, imaging experiments provide simultaneous viewing of different regions of the magnetosphere. Stereo imaging, as done by TWINS, takes the next step of producing 3-D images, and will provide a leap ahead in our understanding of the global aspects of the terrestrial magnetosphere.
