CO2 Monitoring Satellites May Shut Down: What Are The Impacts?
The US government is considering shutting down satellites that watch CO2 in the atmosphere.
These satellites, OCO-2 and OCO-3, help scientists understand climate change and track crops.
They measure how much CO2 is in the air and where it comes from, like from forests or factories.
They also show how healthy plants are.
Scientists use this data to study global warming, and the effects of drought on crops.
It's like having special eyes in space to see the planet's health.
While it cost a lot to build them, keeping them running is much cheaper, and scientists say the information is very valuable.
The Trump administration reportedly plans to shut down NASA's OCO-2 and OCO-3 satellites.
These satellites monitor atmospheric carbon dioxide (CO2) and crop health.
Experts believe the satellites provide crucial data on climate change and crop yields.
OCO-2 measures CO2 and locates its sources, while OCO-3 enhances observations from the ISS.
Maintaining the satellites costs around $15 million per year, compared to the $750 million initial investment.
- Who
