Aspera (spacecraft)
NASA mission to study galaxy evolution
From Wikipedia, the free encyclopedia
Aspera is a NASA small satellite astrophysical mission selected in 2020 as part of the Astrophysics Pioneers Program. The mission is designed to map diffuse extreme-ultraviolet (EUV) emission from hot gas in the circumgalactic medium (CGM) and intergalactic medium (IGM) of nearby galaxies by detecting the O VI doublet at 103.2 and 103.8 nm.[1][2][3][4][5][6]
