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