Which of the following statements with regard to the Square Kilometer Array (SKA) project is/are correct? 1. SKA is a state of the art, mega science international facility to build the world's biggest and most sensitive radio telescope for addressing a wide variety of cutting-edge science goals. 2. The Government of India has accorded its approval for India's participation in the international mega science project. Select the answer using the code given below:
Understanding the Square Kilometer Array (SKA) Project
The question asks us to evaluate the correctness of two statements concerning the Square Kilometer Array (SKA) project, a significant international scientific endeavor.
Analyzing Statement 1: SKA as a Mega Science Facility
Statement 1 describes the SKA as a state-of-the-art, mega-science international facility aimed at constructing the world's largest and most sensitive radio telescope to address various cutting-edge scientific goals. Let's break this down:
- Mega Science Project: The SKA is indeed classified as a mega-science project due to its massive scale, complexity, international collaboration, and significant funding requirements.
- Radio Telescope: It is fundamentally a radio telescope designed to observe the universe at radio wavelengths.
- World's Biggest and Most Sensitive: The SKA is being built to be the largest and most sensitive radio telescope ever constructed, significantly surpassing existing facilities in capability.
- Addressing Science Goals: The project aims to tackle fundamental questions in astrophysics and cosmology, such as the formation and evolution of galaxies, the nature of dark energy, the origin of cosmic magnetism, and the search for extraterrestrial life.
Based on the goals and characteristics of the SKA project, Statement 1 accurately describes its nature and ambition.
Analyzing Statement 2: India's Participation in SKA
Statement 2 asserts that the Government of India has approved India's participation in this international mega-science project. India, through institutions like the National Centre for Radio Astrophysics (NCRA) of the Tata Institute of Fundamental Research (TIFR), has been actively involved in the SKA project from its early stages, participating in design and development activities. The formal approval by the Government of India for joining the SKA Observatory (SKAO), the intergovernmental organisation responsible for building and operating the SKA telescopes, signifies India's commitment to contributing significantly to the construction and operation phases of this global facility.
Therefore, Statement 2 is also factually correct regarding India's official involvement in the Square Kilometer Array project.
Conclusion
Both statements provide accurate information about the Square Kilometer Array (SKA) project:
- Statement 1 correctly identifies SKA as a major international radio telescope project aiming for unprecedented scale and sensitivity.
- Statement 2 correctly states that the Government of India has approved India's participation in the SKA project.
Since both statements are correct, the appropriate answer is the one that indicates both statements are correct.

Additional Information: India's Role in SKA and Radio Astronomy
India has a strong history in radio astronomy, notably with facilities like the Giant Metrewave Radio Telescope (GMRT) near Pune, which has been a precursor and testbed for some SKA technologies. India's participation in the SKA project involves contributing scientific, technical, and financial resources. Indian scientists and engineers are involved in various aspects, including software development, data processing, and telescope design. This participation provides India access to world-leading astronomical data and fosters technological advancements and scientific collaboration.
