Science & Technology Current Affairs - 2026-09-27

Background: ISRO is developing the Next Generation Launch Vehicle (NGLV) to replace the PSLV and GSLV series with a cost-effective, reusable design. Current Context: On September 26, 2026, ISRO successfully conducted a hot test of its 2000kN semi-cryogenic engine at the Mahendragiri facility. This engine uses refined kerosene (Isrosene) and liquid oxygen. Impact: This milestone significantly boosts India's heavy-lift capability, enabling the launch of heavier satellites and future human spaceflight missions with greater efficiency and lower costs, marking a major leap in indigenous space propulsion technology.

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-interferometer components have reached a critical phase. The project is a collaboration between the Department of Atomic Energy, DST, and international LIGO laboratories. 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, positioning India as a global hub for astrophysics.
