NASA Initiates Closeout of OCO-2 and OCO-3 Satellites Under Trump Budget Proposal

Decommissioning plans will begin before October’s fiscal year start, fueling an urgent push for congressional or private funding to avoid a carbon-monitoring gap.

Overview

  • The Trump administration’s FY2026 budget request eliminates operational funding for NASA’s Orbiting Carbon Observatory missions, setting the stage for OCO-2’s deorbit and OCO-3’s shutdown.
  • NASA has moved both satellites into Phase F closeout planning and invited external partners to sustain OCO-3 operations by the August 29 deadline.
  • Experts emphasize that OCO-2 and OCO-3 remain fully functional and that OCO-2’s onboard fuel could support data collection into the 2030s at a low annual cost.
  • Analysts warn that ending the missions would create a multiyear void in high-precision CO2 and photosynthesis measurements crucial for climate research and agricultural forecasting.
  • Researchers and advocacy groups are lobbying lawmakers and exploring public-private partnerships to secure funding and prevent irreversible data loss.
