📖 Introduction
What is PRATUSH?
PRATUSH is an innovative Indian project, conceptualized as a specialized radio telescope. Its unique design specifies its placement on the far side of the Moon, a location chosen for its scientific advantages.
PRATUSH is a collaborative endeavor, developed jointly by two leading Indian scientific organizations:
- The Raman Research Institute (RRI), based in Bengaluru.
- The Indian Space Research Organisation (ISRO).
Core Objective: Unveiling Cosmic Dawn
The primary scientific objective of PRATUSH is to explore the mysteries of the early universe. It specifically targets the epoch known as Cosmic Dawn.
The Cosmic Dawn represents a crucial period in universal history. It marks the time when the first sources of radiation, including the very first stars and galaxies, began to form.
PRATUSH aims to precisely determine the timing and fundamental characteristics of these inaugural star formations. This includes understanding the specific colour of the light emitted during this profound era.
Ultimately, the mission seeks to trace the universe's evolution. It aims to map its journey from an initial state of cold gas, following the Big Bang, to the complex structure of stars, galaxies, and the cosmos we observe today.
Advanced Capabilities of PRATUSH
To achieve its ambitious scientific goals, PRATUSH is equipped with highly sophisticated radio equipment, tailored for deep space observation.
- Frequency Range: It is designed to operate across a broad frequency spectrum, specifically from 30 to 250 MHz.
- Observation Strategy: The telescope will continuously monitor large areas of the sky.
- Data Acquisition: It will record highly detailed radio spectra.
- Spectral Resolution: It boasts an impressive resolution of 100 kHz for precise spectral analysis.
The system incorporates several custom-engineered components essential for its performance:
- A specially designed antenna to capture faint radio signals.
- An advanced analog receiver for initial signal processing.
- A sophisticated digital correlator, crucial for high-resolution spectral analysis of the collected data.
