Notes: The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite has recently reached the Indian Space Research Organisation’s (ISRO) spaceport at Sriharikota. It is a joint mission between the National Aeronautics and Space Administration (NASA) and ISRO to study Earth’s changes. NISAR uses Synthetic Aperture Radar (SAR) technology to send energy pulses and measure how much is reflected back from Earth. This helps in capturing sharp images of the Earth even during darkness or cloudy weather. It detects changes in land, forests, and ice, and is useful for monitoring natural disasters and soil conditions.

Notes: India is set to test its most advanced indigenously developed missile called the Extended Trajectory-Long Duration Hypersonic Cruise Missile (ET-LDHCM). It is indigenously developed by the Defence Research and Development Organisation (DRDO) under a program named Project Vishnu. It is a long-range missile that travels at hypersonic speeds, meaning it is over five times the speed of sound. It can be launched from land, sea, or air, giving India flexible strike capabilities.
