Space Exploration: Artemis Programme and Human Spaceflight
The NASA-led Artemis programme aims to return humans to the Moon for the first time since Apollo 17 (1972) and establish a sustainable lunar presence as a stepping stone to Mars. Artemis I (uncrewed, 2022) tested the Space Launch System (SLS) and Orion capsule. Artemis II (crewed, 2026) is the first crewed test flight, carrying four astronauts on a free-return trajectory around the Moon without landing. India's connection: ISRO and NASA have a Joint Declaration on human spaceflight cooperation, and Indian astronaut Shubhanshu Shukla is set to travel to the International Space Station under the AXIOM-4 mission.
- Artemis II crew: Commander Reid Wiseman, Pilot Victor Glover, Mission Specialists Christina Koch and Jeremy Hansen
- Distance achieved: 406,773 km from Earth — surpassing Apollo 13's 1970 record of 400,171 km
- Orion capsule + SLS: first crewed deep-space vehicle in 50+ years
- Lunar Gateway: planned orbital space station around the Moon for future Artemis missions
- India's Gaganyaan programme: targeting crewed orbital flight; ISRO astronauts undergoing training in Russia and India
Connection to this news: The Artemis II milestone is a landmark in the new era of crewed deep-space exploration, directly relevant to UPSC questions on space missions, international cooperation, and India's own Gaganyaan aspirations.
Physical Activity, Sedentary Behavior, and Public Health
The relationship between lifestyle factors and non-communicable diseases (NCDs) is a major theme in UPSC health policy questions. India faces a dual burden of disease: communicable diseases persist while NCDs (cardiovascular disease, diabetes, cancer, dementia) are rising rapidly, particularly in urban populations where sedentary occupations are more prevalent. The WHO Global Action Plan on Physical Activity (GAPPA) 2018–2030 targets a 15% reduction in physical inactivity globally by 2030.
- India's NCD burden: cardiovascular diseases, diabetes, cancer, and mental/neurological disorders account for ~63% of deaths
- National Programme for Non-Communicable Diseases (NPNCD): India's flagship NCD prevention program
- WHO recommends 150–300 minutes of moderate-intensity aerobic activity per week for adults
- Dementia: ~8.8 million people in India living with dementia (2023 estimates); cases projected to triple by 2050
- Sedentary behavior is independently linked to type 2 diabetes, cardiovascular disease, and metabolic syndrome even among those meeting exercise recommendations
Connection to this news: The meta-analysis quantifying dementia risk reduction from physical activity provides scientific grounding for India's preventive health policies, including Fit India Movement and Khelo India initiatives.
Deep Tech and Innovation Ecosystem in India
"Deep tech" refers to startups and technologies grounded in substantial scientific or engineering innovation — including quantum computing, AI, advanced materials, biotechnology, and space tech. India's National Deep Tech Startup Policy (draft, 2023) and schemes like Startup India, TIDE 2.0, and the Technology Innovation Hubs under NM-ICPS aim to accelerate deep tech commercialization. Incubators at IITs and SRM University are central to this ecosystem.
- India ranked 40th in the Global Innovation Index 2024 (up from 81st in 2015)
- NM-ICPS (National Mission on Interdisciplinary Cyber-Physical Systems): ₹3,660 crore, 25 Technology Innovation Hubs
- TIDE 2.0 (Technology Incubation and Development of Entrepreneurs): supports ICT-based startups
- Startup India: 1,40,000+ recognized startups as of 2025; India is third largest startup ecosystem globally
- SRM University has been designated as one of India's Institute of Eminence (IoE) institutions
Connection to this news: The Deep Tech Summit signals industry-academia collaboration aimed at translating frontier research into commercializable products — a key gap India must bridge to compete with China, the US, and EU in critical technologies.
