NASA, ISRO's NISAR to launch in Jan 2024. Mission to survey Earth's land/ice-covered surfaces every 12 days. Tests, incl. vibration, pending. NISAR to map entire globe, provide data to understand changes in ecosystems, ice mass, vegetation biomass, sea level rise, natural hazards.
The NASA-ISRO Synthetic Aperture Radar (NISAR) is set to be launched in the first quarter of 2024 after a few tests, particularly those related to vibration, NASA officials have said.
"ISRO is projecting the first quarter of next year. So, I mean, that's ready," NASA NISAR Project Manager Phil Barela said during a media interaction in Benglauru on November 15.
He is expecting the launch of NISAR (spelt as 'Naisar') "not earlier than January" from the Satish Dhawan Space Centre at Sriharikota aboard the ISRO Geosynchronous Satellite Launch Vehicle Mark-II.
The mission, which has three-year duration, aims to survey all of Earth's land and ice-covered surfaces every 12 days. This will start after a 90-day satellite commissioning period.

Regarding the key tests that are pending to be undertaken, Mr. Barela said, "The vibration testing that's underway, but there's a whole slew of performance tests that we need to do."
Battery and simulation tests have to be done to make sure that the system works fine, he said.
