NISAR [NASA-ISRO SAR] mission - Visual Cards
NISAR [NASA-ISRO SAR] mission
The NISAR mission is scheduled for launch in 2023.
ISRO has already delivered the S-band SAR payload to NASA for NISAR [NASA-ISRO SAR] mission.
- It is optimized for studying hazards and global environmental change
- It can help manage natural resources better and provide information to scientists to better understand the effects and pace of climate change.
- It will scan the globe every 12 days over the course of its three-year mission
- It will be imaging the Earth’s
- ice sheets
- sea ice
- It will detect movements of the planet’s surface as small as 0.4 inches over areas about half the size of a tennis court.
- NASA will provide
- one of the radars for the satellite,
- a high-rate communication subsystem for science data,
- GPS receivers
- A payload data subsystem.
- ISRO will provide the
- spacecraft bus,
- The second type of radar (called the S-band radar),
- The launch vehicle and associated launch services.
- NISAR will be equipped with the largest reflector antenna ever launched by NASA
- Reflector’s primary goals include
- Tracking subtle changes in the Earth’s surface,
- Spotting warning signs of imminent volcanic eruptions,
- Helping to monitor groundwater supplies
- Tracking the rate at which ice sheets are melting.
Synthetic Aperture Radar
- The name NISAR is short for NASA-ISRO-SAR.
- SAR refers to the synthetic aperture radar
- NASA will use SAR to measure changes in the surface of the Earth.
- SAR refers to a technique for producing high-resolution images.
- Because of the precision, the radar can penetrate clouds and darkness, which means that it can collect data day and night in any weather.
