ISRO Prepares for Launch: Insat-3DS Satellite and Nasa’s Nisar Mission

The Indian Space Research Organisation (ISRO) has successfully completed crucial tests on the Insat-3DS satellite. The final review is pending, and once completed, the satellite will be transported to the spaceport in Sriharikota, Andhra Pradesh, for launch.

Launch Details and Timeline

The satellite is set to be launched using ISRO’s GSLV launch vehicle. According to the latest Notice to Air Missions (NOTAM) issued by ISRO, the launch window is scheduled between February 17 and March 17.

Significance of Insat-3DS in Climate Observation

Insat-3DS is part of a series of climate observatory satellites by India, following the launch of Insat-3DR in 2016. The successful launch of Insat-3DS not only signifies the placement of an advanced Indian meteorological satellite but also serves as a qualification for the GSLV for the upcoming Nasa-Isro Synthetic Aperture Radar (Nisar) satellite launch.

Nasa’s Update on Nisar

Nasa’s latest update on the Nisar satellite highlights its role in measuring key Earth vital signs. Nisar, equipped with a synthetic aperture radar (SAR), will monitor various aspects, including the health of wetlands, ground deformation caused by volcanoes, and changes to ice sheets, glaciers, and sea ice. The detailed observations aim to enhance our understanding of how small-scale processes contribute to significant changes in Earth’s cryosphere.

Insights into Earth’s Ice and Snow-Covered Environments

Nisar is expected to provide the most comprehensive picture to date of motion and deformation in Earth’s ice- and snow-covered environments, collectively known as the cryosphere. By studying these changes in fine detail, researchers aim to decipher the impact of climate change on processes like ice melting and motion in regions such as Antarctica, Greenland, mountain glaciers, and sea ice around the world.

Nisar’s Contribution to Climate Understanding

Nasa emphasizes that Nisar’s capabilities will contribute valuable measurements to better understand the processes at play in Earth’s changing climate. Researchers, such as glaciologist Alex Gardner from the Jet Propulsion Laboratory, believe that Nisar will play a crucial role in providing insights into the accelerated motion and melting of Earth’s ice, ultimately aiding in our understanding of these dynamic processes.
