Earth-observation satellite for NASA and ISRO’s NISAR mission successfully went through 3 weeks of thermal and vacuum testing

We recently updated you about the upcoming collaborative mission between NASA and ISRO, mission NISAR. The NISAR (NASA-ISRO Synthetic Aperture Radar) mission is scheduled to be launched in early 2024. Mission NISAR will do a detailed mapping of the Earth to gain insights into forests and wetlands, with an Earth observation satellite. The Earth-observation satellite is jointly developed by ISRO and NASA.

In the latest developments, the Indian Aerospace Defence News updated on the social media platform X, that ISRO successfully conducted an intensive 3 weeks of thermal & vacuum testing of the NISAR earth-observation satellite.

The NISAR satellite has completed its 21-day trial. In this trial, the satellite was put into assessment under probable conditions that it could enter the cosmos. The 3 weeks of trial happened from October 19 to November 13, 2023.

ISRO and NISAR assessed the satellite’s thermal systems and the L-band and S-band radars at their Jet Propulsion Laboratory. The test trials put the satellite under extreme temperature conditions, which it has a chance of encountering in space.

NISAR will map the entire Earth every 12 days. At the same time, researchers and analysts will continuously provide spatial and temporal data, which will be studied to understand various phenomena of the Earth.
