NASA to Switch Off 24-Year-Old Aqua Satellite as Space Debris Threatens Climate Data
1 articles · Updated · Space.com · May 20
NASA plans to deactivate Aqua in the fall, ending nearly 25 years of Earth observation with less than 30 kilograms of fuel left for its controlled reentry.
At least 32 debris-avoidance maneuvers since 2005 have drained fuel and sometimes corrupted datasets, while rising orbital clutter has already created gaps in Aqua’s fire-tracking and climate records.
Low Earth orbit debris tracked by ESA has climbed from about 16,000 objects in 2005 to more than 44,000 in 2026, with collision risk up 20% since 2024.
Aqua’s MODIS instrument has helped detect wildfires faster than ground reports and supported more than 30,000 scientific papers, making its loss hard to replace.
NASA says fire detection will continue through VIIRS on other satellites, while private firms including Google are developing new constellations to fill monitoring gaps.

End of NASA’s Aqua Satellite After 24 Years: Climate Data Loss and the Growing Threat of Space Debris
Overview
NASA's Aqua satellite, launched in 2002, is set for decommissioning in May 2026 after providing 24 years of vital Earth observation data—far beyond its original mission. This decision follows a broader U.S. government trend of budget reevaluation, including efforts to reduce NASA’s operational costs and redirect resources. While Aqua became a cornerstone for climate and water cycle research, its end raises concerns among scientists about potential anti-climate science motives and the impact of losing continuous, high-quality data. The satellite’s retirement highlights the challenges of balancing scientific needs with shifting political and financial priorities.
