For space, I feel UPSC is not focusing on 'smaller' missions like going to Mars and Moon. It's going for more 'exotic' missions like e-LISA which is a Gravitational wave observatory just like LIGO which was asked couple of years ago. So, that maybe narrows down a little bit.What are the important topics for Science & Tech? Please comment what you feel!
- Nuclear treaty and nuclear Energy- Biotech (Gene editing, GM crop, RNA, DNA, embryo twinning)
- Space related ( Perseverance, Chandrayaan, Debris)
- IT (5g, AI, Quantum, Blockchain, data security related)
- Health - VAccine
-Energy( geothermal, Hydrogen gas, fuel cells, solar )
also Large Hadron Collider and wo International proj jisme Fusion reactor banaane ki koshish kar rhe....forgetting the name
