How NASA Is Homing in From Space on Ocean Debris

Space-based technology could help track plastic and other flotsam by its ‘fingerprints.’ In late 2025, scientists reported that, for the first time, they were able to detect concentrations of plastic pollution on land using NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) sensor aboard the International Space Station.

NASA Sensor on Space Station Eyes Contamination off California Coast

Proof-of-concept results from the mouth of the Tijuana River in San Diego County show how an instrument called EMIT could aid wastewater detection. An instrument built at NASA’s Jet Propulsion Laboratory to map minerals on Earth is now revealing clues about water quality.

NASA Data Reveals Role of Green Spaces in Cooling Cities

As any urban dweller who has lived through a heat wave knows, a shady tree can make all the difference. But what happens when there’s no shade available? A recent study in Nature Communications used NASA satellite data to identify a major gap in global resilience to climate change: cities in the Global South have […]
