सारांश
The United States recently announced ambitious plans to deploy a small nuclear reactor on the moon by the early 2030s, marking a significant step towards establishing a permanent power source beyond Earth's orbit. This move underscores the growing importance of nuclear power for sustained human presence in space, especially for long lunar nights and resource utilization on Mars, where solar energy is insufficient. Nuclear fission reactors, much more powerful than current radioisotope thermoelectric generators (RTGs), could power habitats, laboratories, and even enable faster deep-space travel.
However, this technological leap exposes a critical gap in international law. Existing frameworks like the UN Principles on Nuclear Power Sources in Outer Space, the Outer Space Treaty, and the Liability Convention offer only partial or non-binding coverage, leaving ambiguities regarding safety standards, environmental contamination, and accident liability. This legal vacuum necessitates urgent reform to prevent potential conflicts and ensure responsible development of nuclear technologies in space, with India having a potential leadership role in championing safe practices.
पृष्ठभूमि
The concept of using nuclear power in space dates back to the early days of space exploration, with Radioisotope Thermoelectric Generators (RTGs) powering missions like Voyager, Cassini, and Perseverance rover. These RTGs convert heat from the natural decay of radioactive isotopes into electricity.
However, for more ambitious, long-duration human missions and permanent bases on celestial bodies like the Moon or Mars, RTGs offer insufficient power. Nuclear fission reactors, which generate power through controlled nuclear chain reactions, offer significantly higher power outputs, making them crucial for powering habitats, resource extraction (e.g., water ice), and advanced propulsion systems for deep-space travel.
नवीनतम घटनाक्रम
The United States has announced plans to deploy a small nuclear fission reactor on the Moon by the early 2030s, aiming to provide a robust and continuous power source, especially vital during the long lunar nights. This initiative is part of a broader global push towards establishing a sustained human presence beyond Earth.
While technologically promising, this development highlights a critical 'legal vacuum' in international space law. Existing frameworks, primarily the Outer Space Treaty (1967), the Liability Convention (1972), and the non-binding UN Principles on Nuclear Power Sources in Outer Space (1992), do not adequately address the specific safety standards, environmental contamination risks, and liability for accidents involving advanced nuclear fission reactors in space.
बहुविकल्पीय प्रश्न (MCQ)
1. Consider the following statements regarding the deployment of nuclear power sources in outer space: 1. The United States' plan to deploy a small nuclear reactor on the moon by the early 2030s aims to establish a permanent power source for sustained human presence. 2. The Outer Space Treaty of 1967 explicitly provides a comprehensive and binding framework for the safety standards and liability associated with nuclear power sources in space. 3. Nuclear fission reactors are generally much more powerful than Radioisotope Thermoelectric Generators (RTGs) for large-scale power requirements in space habitats. Which of the statements given above is/are correct?
- A.1 only
- B.1 and 2 only
- C.1 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: C
Statement 1 is correct. The news explicitly states this as the US's ambition for sustained human presence and power during long lunar nights. Statement 2 is incorrect. The news highlights that existing frameworks like the Outer Space Treaty offer only 'partial or non-binding coverage' and a 'legal vacuum' exists regarding safety standards and liability for nuclear power sources. Statement 3 is correct. The news states that 'Nuclear fission reactors, much more powerful than current radioisotope thermoelectric generators (RTGs), could power habitats, laboratories...'. RTGs are suitable for lower power needs over long durations, while fission reactors offer significantly higher power output.
2. With reference to international legal frameworks governing activities in outer space, consider the following statements: 1. The Outer Space Treaty (1967) prohibits the placement of nuclear weapons or any other weapons of mass destruction in Earth orbit or on celestial bodies. 2. The Liability Convention (1972) establishes international rules and procedures concerning liability for damage caused by space objects. 3. The UN Principles Relevant to the Use of Nuclear Power Sources in Outer Space (1992) are legally binding on all signatory states, providing detailed safety standards. Which of the statements given above is/are correct?
- A.1 only
- B.1 and 2 only
- C.2 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is correct. Article IV of the Outer Space Treaty explicitly prohibits placing nuclear weapons or any other weapons of mass destruction in orbit around the Earth, on celestial bodies, or stationing them in outer space in any other manner. Statement 2 is correct. The Convention on International Liability for Damage Caused by Space Objects (Liability Convention) elaborates on Article VII of the Outer Space Treaty, establishing a framework for liability for damage caused by space objects. Statement 3 is incorrect. The news article explicitly states that the UN Principles on Nuclear Power Sources in Outer Space offer 'non-binding coverage.' These principles are recommendations adopted by the UN General Assembly and are not a legally binding treaty.
3. Which of the following statements best describes the primary advantage of using nuclear fission reactors over Radioisotope Thermoelectric Generators (RTGs) for future long-duration human missions on the Moon or Mars?
- A.Fission reactors are inherently safer and produce less radioactive waste than RTGs.
- B.Fission reactors can provide significantly higher power output, essential for large habitats and resource utilization.
- C.RTGs require a constant supply of sunlight, making them unsuitable for lunar nights or Mars.
- D.Fission reactors have a much longer operational lifespan, requiring less frequent refueling.
उत्तर देखें
सही उत्तर: B
The news states: 'Nuclear fission reactors, much more powerful than current radioisotope thermoelectric generators (RTGs), could power habitats, laboratories, and even enable faster deep-space travel.' This directly supports option B, highlighting the need for higher power for sustained human presence and activities. A) Fission reactors, while controllable, involve complex safety challenges and produce significant radioactive waste. RTGs use passive decay and are generally considered very robust, though they also contain radioactive material. This statement is incorrect. C) RTGs do not require sunlight; they generate power from radioactive decay. Solar panels require sunlight. This statement incorrectly attributes a characteristic of solar panels to RTGs. D) Both can have long operational lifespans, but the primary advantage highlighted for fission reactors in the context of future large-scale missions is their significantly higher power output, not necessarily a longer lifespan compared to RTGs which can operate for decades.
