These pages represent a consortium of scientists to assess the possibility of a space-based Indian mission to observe the anisotropies as well as the spectral distortions in the Cosmic Microwave Background (CMB).

In response to Announcement of Opportunity (AO) by the Indian Space Research Organization (ISRO), the consortium had submitted the following proposal to on April 16, 2018: Exploring Cosmic History and Origin (a proposal for a next generation space mission for near-ultimate measurements of the CMB polarization and discovery of global CMB spectral distortions). The executive summary of the proposal is available here.
