Consider the following statements with reference to PRATUSH telescope:...
Astronomers are looking forward to opening a new window on the universe by posting high-resolution telescopes on the moon, and in orbit around it including one from India called PRATUSH.
- Probing ReionizATion of the Universe using Signal from Hydrogen (PRATUSH) is a radio telescope to be sited on the moon’s far side.
- It is being built by the Raman Research Institute (RRI) in Bengaluru with active collaboration from the Indian Space Research Organisation (ISRO).
- Initially, ISRO will place PRATUSH into orbit around the earth. After some fine-tuning, the space agency will launch it moonwards.
- Main roles: It will be to detect signals from the first stars and galaxies, reveal the cosmic dawn of the universe, answering the question when the first stars formed, the nature of the first stars and what was the light from the first stars.
- It will carry a wideband frequency-independent antenna, a self-calibrating analog receiver and a digital correlator to catch radio noise in the all-important signal from the Dark Ages.
- The target instrument sensitivity is at the level of few millikelvin without being limited by any systematic features.
Hence only statement 1 is correct.

Consider the following statements with reference to PRATUSH telescope:...
PRATUSH Telescope
1. Statement 1: It is a radio telescope developed by the Raman Research Institute and the Indian Space Research Organisation (ISRO).
- This statement is correct. PRATUSH (Polarized Radiometer for Atmospheric Transmission and Understanding of Scattering at High frequencies) telescope is indeed a radio telescope developed jointly by the Raman Research Institute and ISRO.
2. Statement 2: It aims to study the impact of radio waves on the outer environment of the Earth.
- This statement is not correct. The main aim of PRATUSH telescope is to study the Earth's upper atmosphere and ionosphere using radio waves. It is designed to monitor the Earth's ionosphere and study phenomena such as ionospheric scintillations.
Therefore, the correct answer is option A - 1 only.
