The HELIX experiment utilizes an all-reflective spatial heterodyne spectrometer (RSHS) to achieve a high spectral resolving power of R~250,000 for geocoronal hydrogen mapping. By combining high etendue with a compact, self-scanning FTS format, it enables detailed lineshape analysis of Ly-alpha emission. This capability is critical for understanding hydrogen exosphere dynamics and terrestrial planetary atmospheres.
