Discover How Climate Satellites Are Revolutionizing Our Understanding of Earth’s Environment

The Trump administration has proposed plans to end two vital NASA satellite missions aimed at tracking greenhouse gases. Current and former NASA staff say this could permanently shut down one of these missions, leading to its satellite burning up in the atmosphere.

These missions, the Orbiting Carbon Observatories (OCO), collect crucial data on carbon dioxide and plant health. Scientists, farmers, and even energy companies rely on this information. Importantly, they are the only federal missions designed specifically to measure greenhouse gases.

The exact reasons behind this potential termination are unclear. Experts who worked on the OCO missions assert that the technology is advanced and should remain operational for years. A recent report from NASA praised the high quality of the data from these missions and recommended extending their run for at least three more years.

The OCO missions use similar tools to gauge carbon dioxide levels and monitor plant growth worldwide. One of these tools is mounted on a standalone satellite, while the other is on the International Space Station (ISS). Closing one mission would mean significant loss of valuable scientific data.

David Crisp, a retired NASA engineer, reported that he has been contacted for advice on termination plans. He expressed concern over the implications, stating that team members were under pressure to create these plans, raising questions about the future of ongoing projects.

Interestingly, other academics who also utilize OCO data have faced similar inquiries, but they asked to stay anonymous for fear of reprisal against NASA employees.

Both current and former NASA staff indicated that the directives to create plans for mission termination came from higher-up budget discussions. This follows President Trump’s FY 2026 budget proposal, which suggests funding cuts that could impact these crucial projects.

Congressional Funding and Future Implications

Presidential budget proposals often differ greatly from what Congress ultimately decides. The OCO missions are funded through September 2025, thanks to Congress’s previous allocations. Current budget discussions suggest that NASA’s funding is unlikely to change drastically, leaving hope for the continued operation of the OCO missions.

In a recent letter, Democrats in Congress urged NASA to maintain these missions, arguing that attempts to terminate them undermine congressional authority. They believe that ending funding for Earth-observing satellites could have dire consequences for climate monitoring and disaster response.

Surprising Discoveries from OCO Data

Originally designed to monitor carbon dioxide levels, the OCO missions unintentionally began measuring plant photosynthesis as well. This happy accident has provided scientists with detailed maps of agricultural productivity worldwide. Scott Denning, a climate scientist, remarked on the unexpected benefits of these observations. They are now invaluable for crop monitoring, assisting farmers in tracking growth patterns and better managing resources.

The U.S. Department of Agriculture and various agricultural firms utilize this data to predict crop yields and assess drought conditions. Such insights can even impact political stability, as food shortages often lead to migration crises. For instance, prolonged drought in Honduras has pushed many farmers to seek opportunities elsewhere.

The Impact of Carbon Data

The OCO missions have changed the understanding of how carbon dioxide accumulates in our atmosphere. While earlier science suggested tropical forests absorbed significant amounts of CO2, new findings from satellite data show that boreal forests in northern areas may do even more.

The wide-ranging impact of this data cannot be overstated. Researchers highlight that as climate patterns shift, understanding which regions sequester carbon is becoming increasingly important. The satellite missions continue to generate critical insights that can assist in climate modeling and policy decisions.

Cost-Effectiveness of Maintaining Satellite Missions

Maintaining the OCO missions is relatively inexpensive compared to their initial costs. The two projects cost about $750 million to set up but require only roughly $15 million annually to operate. David Crisp argues that terminating these missions economically doesn’t make sense, considering the wealth of data they provide.

Recent initiatives from NASA to involve private companies in maintaining satellite operations indicate a shift towards privatization. While some scientists see value in private-sector contributions to satellite data collection, they caution that these efforts would not be possible without the initial investments made through public funding.

In summary, the fate of the OCO missions hangs in the balance, with significant implications for both climate science and policy. To learn more about NASA’s budget discussions or get involved, check out NASA’s official updates.
