The most awaited joint satellite project between the Indian Space Research Organisation (ISRO) and NASA, known as the NASA-ISRO Synthetic Aperture Radar (NISAR) is scheduled to be launched in March 2025, as per Union Minister Jitendra Singh. The announcement was made during a written reply to a question asked in the Lok Sabha.
NISAR, a cutting-edge Earth observation satellite was slated to be launched in early 2023 but because of some technical issues led to the delay. The issues with the satellite were identified by NASA scientists. The problem was with the satellite’s 12-meter radar antenna reflector. This crucial component required to be fixed and transported to the United States for repair. After the rectification was done, the reflector was shipped back to India in October 2023. It is currently undergoing reintegration with the satellite and is going through rigorous testing.
Reasons behind the delay
Minister Singh also underlined additional challenges impacting the satellite’s deployment. The delay in the launch is also increasing because of the ongoing ‘’eclipse season’’ which is not a favourable condition for the deployment of NISAR’s boom and radar antenna reflector. These environmental and technical factors have contributed to the delay and have pushed the launch window to March 2025.
NISAR represents a remarkable collaboration between ISRO and NASA and aims to provide data for understanding Earth’s ecosystems, climate change, and natural disasters. The satellite will be able to do it by using advanced radar technology to study Earth’s surface with exceptional accuracy. The data retrieved will also provide valuable insights into environmental changes, resource management, and natural calamities.
The delay in the launch also showcases the rigorous standards that have been practiced for such high-stakes projects. Once the mission becomes operational, NISAR is anticipated to revolutionize Earth’s observation potential. The joint venture will also result in reinforcing ISRO and NASA’s shared commitment to make advancements in the field of space and for global benefit.
