SPHEREx

(Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer)
(all-sky spectral survey space-mission plan)

SPHEREx (for Spectro-Photometer for the History of the Universe, Epoch of Reionization (EOR), and Ices Explorer) is a space mission plan under consideration by NASA for a telescope and spectrograph to survey the whole sky. It would be launched in the early 2020s.

Current thoughts are a 20cm telescope with a Spectrograph with an Angular Resolution of 6.2 arcseconds, a Spectral Resolution (R) of 120, covering the Wavelength-range .075 to 4.18 micrometers. This would give it the ability to pursue numerous science goals.
