Space governance and nuclear technology: a GS3 Science & Technology and International Relations case study.
Why in news
NASA, China, and Russia are developing lunar nuclear reactors to power permanent lunar bases, raising concerns over radiation risks and potential violations of the 1967 Outer Space Treaty.
Background
NASA requested a reactor for the Moon's south pole by December 2030 to generate 20 kilowatts for five years. Russia's Selena reactor, planned for 2036, aims to provide 10 kilowatts to China's lunar stations.
Facts for Prelims
- S&TNASA's Lunar Reactor 1 is designed to generate 20 kilowatts of electricity and operate for five years without intervention.
- S&TRussia's Selena reactor is designed to generate up to 10 kilowatts and run autonomously for a decade.
- FactLunar nights last more than two weeks on Earth's calendar, making solar energy alone insufficient for permanent bases.
- BodyThe 1967 Outer Space Treaty is the primary international framework governing space activities and potential nuclear usage.
Prelims practice question
Which international framework governs space activities and potential nuclear usage in space?
- (a)1967 Outer Space Treaty
- (b)Antarctic Treaty
- (c)UN Charter
- (d)Geneva Convention
Show answer
Answer: (a) 1967 Outer Space Treaty — The 1967 Outer Space Treaty is the primary international framework governing space activities and potential nuclear usage.
For Mains
Q. Discuss the technical and legal challenges associated with deploying nuclear reactors for lunar exploration under the framework of the Outer Space Treaty.
Dimensions to cover in your answer
- Regulatory vacuum: Lack of specific international protocols for nuclear waste management and containment in lunar environments.
- Safety-Security dilemma: Risk of radioactive dispersal during launch failures vs. the necessity of high-output power for deep-space missions.
- Geopolitical friction: Potential for 'first-mover' advantage in lunar resource extraction leading to non-cooperative space governance.
