11. South Korea's KSTAR Sustains Plasma for 102 Seconds – Nuclear Fusion Milestone

Why in News?

South Korea's KSTAR (Korea Superconducting Tokamak Advanced Research) device sustained plasma in high-confinement mode (H-mode) for 102 seconds, a major milestone in controlled nuclear fusion research. This experiment was conducted between December 2023 and February 2024 but findings were formally published and globally highlighted in 2026.

Key Points

• The 102-second plasma duration significantly exceeds previous records (KSTAR achieved 30 seconds in 2021, 48 seconds in 2022, 100 seconds earlier).
• H-mode (High Confinement Mode) enables denser, hotter plasma — essential for commercial fusion viability.
• KSTAR aims to sustain plasma for 300 seconds by 2026 under its roadmap.
• Nuclear fusion involves fusing light atomic nuclei (usually deuterium and tritium) to release enormous energy — the same process that powers the sun.
• If commercially viable, fusion could provide near-limitless, carbon-free energy.
• India is a partner in the ITER (International Thermonuclear Experimental Reactor) project in France — the world's largest fusion experiment.

Static Knowledge

• ITER is being constructed in Cadarache, southern France; India is one of the seven ITER partners (EU, USA, Russia, China, Japan, South Korea, India).

• The JWST's NIRSpec (Near-Infrared Spectrograph) instrument was used for spectral analysis.
• 1I/'Oumuamua (2017) showed non-gravitational acceleration but no confirmed composition; 2I/Borisov (2019) was the first confirmed interstellar comet with water ice.
• Interstellar objects offer a window into the composition and formation processes of other planetary systems.

Static Knowledge

• JWST was launched on 25 December 2021 by NASA, ESA, and CSA (Canadian Space Agency).
• It is positioned at Lagrange Point 2 (L2), about 1.5 million km from Earth.
• India's space agency ISRO is not a partner in JWST but has collaboration agreements with NASA on other missions.
• Methane is a potential biosignature when found in certain planetary contexts (though 3I/ATLAS is a comet, not a planet).
