NISAR(NASA-ISRO Synthetic Aperture Radar Mission) is joint project between ISRO and NASA for developing and launching a dual frequency synthetic aperture radar on Earth Observation satellite. The cost of the mission is estimated to be a whopping 1.5 Billion USD or 150 Crores INR.
The mass of the satellite is 2800kg and a power of 6500Watts.
It is expected to launch in September 2022 in GSLV Mk.II with a 4 meter fairing at Satish Dhawan Space Center.
It is geocentric, low Earth orbit. It is in sun-synchronous regime. The altitude is 747km with an inclination oh 98.4 degrees. The baseline mission duration is 3 years.
It will be measuring Earth's changing ecosystems, dynamic surfaces and ice mases providing information about the biomass, natural hazards, sea level rise and groundwater and will support a host of other applications.
NISAR will observe Earth's land and ice covered surfaces globally with 12 day regularity on ascending and descending passes, sampling Earth on average every 6 days for a baseline 3-year mission.
The data collected by it can be accessed by anyone.
