Mains-Ready Analytical Notes

Major Debates/Discussions

Space Program: Socio-economic benefits vs. "Prestige" projects

Balancing missions with direct developmental applications (remote sensing, communication) versus ambitious exploratory missions (Gaganyaan, interplanetary). Justification of costs in a developing country. (ISRO consistently argues for long-term benefits and indigenous capability development).

Private Sector in Space: Benefits vs. Concerns

Potential benefits (innovation, investment, speed) versus concerns (ISRO's role dilution, national security, equitable access). Need for robust regulation (IN-SPACe's role).

DPI: Inclusion vs. Exclusion & Privacy

While DPIs like Aadhaar and UPI have driven inclusion, concerns about data privacy, security, digital divide, and potential for exclusion of marginalized groups without digital access/literacy persist.

GM Crops: Science-based benefits vs. Concerns

Science-based benefits (yield, pest resistance) versus concerns about environmental impact, farmer autonomy, and corporate control over seeds. The debate over GM mustard is an example.

Nuclear Energy: Clean Energy vs. Safety & Waste Disposal

Balancing the need for low-carbon energy with concerns about nuclear safety, radioactive waste management, and proliferation risks.

Environmental Regulations: Development vs. Conservation

The constant tension between facilitating economic development (ease of doing business) and strengthening environmental safeguards (e.g., EIA debates).

Historical/Long-term Trends, Continuity & Changes

Space: From modest beginnings to complex interplanetary missions and human spaceflight aspirations – a journey of self-reliance and ambition. Shift towards commercialization and private participation is a major change.
