Answer: National Aeronautics and Space Administration (NASA) and Indian Space Research Organisation (ISRO)
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.
