Science & Technology Current Affairs - 2026-10-13

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: As of October 2026, ISRO has successfully completed the 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 enhances India's heavy-lift capability, allowing for larger satellite deployments and future human spaceflight missions. It marks a critical step toward achieving self-reliance in high-thrust propulsion technology for future 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: By mid-October 2026, construction at the Hingoli site has reached a critical phase with the installation of vacuum tube infrastructure. The project is a collaboration between the Department of Atomic Energy, DST, and international LIGO laboratories. Impact: Once operational, LIGO-India will significantly improve the localization of gravitational-wave sources in the sky. It positions India as a global leader in fundamental physics research and enhances international scientific cooperation in astrophysics.
