NASA and India launch groundbreaking $1.5 billion satellite
NASA and ISRO are teaming up for NISAR, a $1.5 billion satellite launching in 2025 from India. This mission uses dual-frequency radar to track changes on Earth's land, ice, and forests with incredible detail—and the best part is, all its data will be free for researchers worldwide.
TL;DR
A powerful new tool for Earth science
NISAR combines NASA's L-band and ISRO's S-band radars, so it can scan the planet day or night, rain or shine. It checks every spot on Earth every 12 days and picks up even tiny shifts on the ground.
A game changer for climate research and disaster response
With both radars working together, NISAR will help scientists study everything from earthquakes to forest health to how much water is in soil. Its high-res data could make a real difference for climate research and disaster response around the world.
