SOLAR SYSTEM

Detailed explanation-1: -Using advanced radar imaging that will provide an unprecedented, detailed view of Earth, the NASA-ISRO Synthetic Aperture Radar, or NISAR, satellite is designed to observe and take measurements of some of the planet’s most complex processes.

Detailed explanation-2: -Mission Name. NASA-ISRO Synthetic Aperture Radar (NISAR)

Detailed explanation-3: -NASA stands for National Aeronautics and Space Administration and the full form of ISRO is the Indian Space Research Organisation.

Detailed explanation-4: -NISAR will be the first radar of its kind in space to systematically map Earth, using two different radar frequencies (L-band and S-band) to measure changes of our planet’s surface, including movements as small as centimeter.

Detailed explanation-5: -The mission is a partnership between NASA and ISRO. Under the terms of the agreement, NASA will provide the mission’s L-band synthetic aperture radar (SAR), a high-rate telecommunication subsystem for scientific data GPS receivers, a solid-state recorder, and a payload data subsystem.

Detailed explanation-6: -NISAR is a Low Earth Orbit observatory jointly developed by NASA and ISRO. NISAR carries L and S dual-band Synthetic Aperture Radar (SAR), which operates with the Sweep SAR technique to achieve large swaths with high-resolution data.

Detailed explanation-7: -Planned Launch Date: 2024 NISAR will observe Earth’s land and ice-covered surfaces globally with 12-day regularity on ascending and descending passes, sampling Earth on average every 6 days for a baseline 3-year mission.
