Science & Technology Current Affairs - 2026-09-26

Background: ISRO is developing the Next Generation Launch Vehicle (NGLV) to replace the PSLV and GSLV series. Current Context: On September 25, 2026, ISRO successfully conducted a hot test of its 2000kN semi-cryogenic engine at the Propulsion Complex in Mahendragiri. This engine uses refined kerosene (Isrosene) and liquid oxygen. Impact: This milestone significantly boosts India's heavy-lift capability, allowing for larger payloads to be launched into orbit. It is a critical step toward achieving self-reliance in space transportation and supporting future human spaceflight missions and deep space exploration.

Background: LIGO-India is a planned advanced gravitational-wave observatory to be located in Maharashtra, part of a global network. Current Context: As of late September 2026, the construction of the vacuum infrastructure and the installation of laser interferometry components have reached a critical phase. The project is a collaboration between the Department of Atomic Energy, DST, and international partners. Impact: Once operational, it will significantly enhance the global ability to detect gravitational waves, providing deeper insights into black hole mergers and the fundamental nature of the universe's evolution.
