- NASA and ISRO launched the $1.5 billion NISAR satellite, the world's most expensive Earth-observation satellite.
- NISAR combines L-band (NASA) and S-band (ISRO) radars to monitor soil moisture, forests, ice, agriculture, and human structures.
- The satellite orbits 464 miles above Earth, collecting data twice every 12 days, including polar regions.
- NISAR features a 39-foot antenna reflector for sending and receiving microwaves to measure surface changes in real-time.
- The mission marks the largest NASA-ISRO collaboration, potentially setting a template for future space cooperation like Artemis.
