NASA space telescope   SPHEREx 
Every exposure images the sky with a central wavelength that varies over the 3.5°x3.5° Band 1 FoV. For a given object, each exposure therefore provides photometry at one wavelength. The spacecraft executes a series of maneuvers to build multiple images, each shifted by 12.3 arcmin. When complete, the ensemble of images gives a full spectrum with at least 24 samples in Band 1.
