| Abstract : | PRATUSH -- Probing ReionizATion of the Universe using Signal from Hydrogen -- is a proposed cosmology experiment to detect the global red-shifted 21-cm signal from the Cosmic Dawn and Epoch of Reionization (CD/EoR). PRATUSH will seek to precisely measure the low-frequency radio sky-spectrum over the frequency range of 40 to 250 MHz in an orbit around the moon. The scientific observations would be made in the radio-quiet region when in the far-side of the moon, and the data would be transmitted back to Earth when in the near-side. PRATUSH was proposed to the Indian Space Research Organisation (ISRO) during a call for proposals in the announcement of opportunity for science payloads in 2018. PRATUSH is in the pre-project studies phase. In this talk we present a mission concept and the baseline design of PRATUSH, optimized to operate over 55 - 110 MHz, and the current status of the development activities. |
