Credit: NASA WASHINGTON — A joint Earth science mission between NASA and its Indian counterpart is now scheduled to launch as soon as next March after being delayed to repair its main radar antenna.In a presentation at the annual meeting of the American Geophysical Union here Dec. 11, Gerald Bawden, program scientist for the NASA-ISRO Synthetic Aperture Radar (NISAR) mission at NASA Headquarters, said the spacecraft is now scheduled to launch from India in a window that opens in late March. NISAR was previously scheduled to launch in the spring of this year, but NASA announced in March that it would delay the launch to make repairs to the spacecraft’s 12-meter deployable reflector used by its main radar instrument.

Technology tamfitronics NISAR satellite to offer precise monitoring of Earth's surface movementsby Clarence OxfordLos Angeles CA (SPX) Nov 09, 2024Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure.Earth's surface is in a state of continuous motion, although often unnoticed. Scientists have utilized satellite and ground-based technology to observe movements linked to geological events such as earthquakes, landslides, and volcanic activity. A new initiative by NASA and the Indian Space Research Organisation (ISRO) aims to enhance this knowledge and potentially aid in disaster preparedness and recovery efforts.The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is set to measure the movement of nearly all land and ice-covered regions on Earth twice within a 12-day period. This frequent data collection will offer researchers...
