Space Debris Threatens Vital Climate Satellites, Increasing Risks and Costs
US · Published May 21, 2026
Space debris is increasingly jeopardizing the functionality of critical climate observation satellites, including NASA's Earth Observing System (EOS) fleet.
The EOS satellites—Aqua, Terra, and Aura—have collectively performed at least 32 evasive maneuvers since 2005 to avoid collisions with orbital debris.
These maneuvers consume precious fuel and can lead to data corruption, impacting the accuracy of climate research.

Why It's Important?

The increasing presence of space debris threatens the longevity and effectiveness of satellites critical for climate monitoring and emergency response. For instance, Aqua's infrared sensors have been instrumental in detecting wildfires and providing real-time data to emergency responders. However, data gaps caused by debris-related maneuvers could hinder such efforts. Additionally, the economic cost of fuel consumption for collision avoidance is significant, shortening satellite lifespans and increasing operational expenses. The risk of collisions is also rising, with a 20% increase in collision likelihood reported since 2024. If satellites like Aqua are unable to avoid debris due to fuel depletion, the risk of catastrophic collisions could escalate, potentially leading to cascading failures in orbit.
