Spec-S5
With first-light in the 2030s, Spec-S5 will be the premier instrument to probe both epochs of accelerated expansion. By mapping 10x more linear modes than DESI + Rubin + CMB-S4 it will dramatically increase our knowledge of early universe physics by mapping the imprint of primordial features over an enormous volume of the distant universe.
