NASA and India have paired up to launch an Earth-mapping satellite capable of tracking the slightest changes in land and ice. The satellite blasted off from India on Wednesday. Scientists say the $1.3 billion mission will help forecasters and first responders stay one step ahead of floods, landslides and other disasters. The satellite, known as NISAR, will survey virtually all of Earth’s terrain multiple times with its two radars. It’s the biggest space collaboration between the two countries. It will join dozens of Earth observation missions already in operation by the U.S. and India.
