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, 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, with Spectrography in two Bands: Wavelength-range .075 to 4.18 micrometer wavelengths with a Spectral Resolution of 41.4, and 4.18 to 5 micrometers with a resolution of 120. It would operate in a low, polar Earth orbit for two years, completing an all-sky survey each 6 months. It would pursue numerous science goals.
