NASA budget cuts threaten public health research tied to climate data

NASA's Earth science program, a vital source of environmental and health data, faces steep funding cuts under the Trump administration that could derail research on climate-linked health risks like Lyme disease and air pollution.

Joanne Kenen reports for Undark Magazine.

In short:

• NASA’s Earth Science Division provides environmental data used to track disease outbreaks, study air quality, and analyze climate impacts on health, including conditions like asthma, malaria, and preterm birth.
• Proposed budget cuts would reduce NASA's funding by nearly 25%, slashing Earth science funding by more than half and prompting early retirements, layoffs, and lab closures.
• Scientists warn that losing access to NASA's satellite data could severely limit efforts to monitor and respond to public health threats, particularly in underserved areas with limited ground-based monitoring.

NASA "really enabled a whole new world of health research that the public health community hadn’t been doing yet.”

Why this matters:

Environmental data collected from space has become a critical tool for public health. NASA’s satellite monitoring helps scientists forecast disease outbreaks, assess the spread of tick- and mosquito-borne illnesses, and track harmful pollutants like wildfire smoke and particulate matter. As climate change shifts weather patterns and intensifies extreme events, these tools offer early warning systems for both local health departments and international health agencies. Cutting this research pipeline could leave vulnerable communities blind to risks that satellites now help illuminate. With fewer resources, efforts to understand how environmental shifts affect everything from pregnancy outcomes to heat-related deaths may falter.
