By tracking subtle changes in Earth’s surface, NISAR will spot warning signs of imminent volcanic eruptions. Monitoring these kinds of changes in the planet’s surface over nearly the entire globe hasn’t been done before with the high resolution in space and time that NISAR will deliver. NISAR is a joint Earth-observing mission between NASA and the Indian Space Research Organization (ISRO). NISAR will launch no earlier than 2022.
