Debris-fueled risk: NASA’s Aqua nears retirement and a lasting climate record teeters
NASA’s Aqua satellite, a cornerstone of the Earth Observing System that has tracked wildfires and climate data for 24 years, is running out of fuel and will soon lose its ability to maneuver away from space debris, threatening gaps in a decades-long climate record as orbital junk rises and no direct replacement is fully funded, with private ventures like Google’s fire-detection plans poised to fill at least part of the data gap.
