Burn the Satellite!

Trump administration takes aim at satellite that measures carbon dioxide and crops
The Trump administration has asked NASA employees to draw up plans to end at least two major satellite missions, according to current and former NASA staffers. If the plans are carried out, one of the missions would be permanently terminated, because the satellite would burn up in the atmosphere.
The data the two missions collect is widely used, including by scientists, oil and gas companies and farmers who need detailed information about carbon dioxide and crop health. They are the only two federal satellite missions that were designed and built specifically to monitor planet-warming greenhouse gases.

Both missions, known as the Orbiting Carbon Observatories, measure carbon dioxide and plant growth around the globe. They use identical measurement devices, but one device is attached to a stand-alone satellite while the other is attached to the International Space Station. The standalone satellite would burn up in the atmosphere if NASA pursued plans to terminate the mission. -
Interesting bits that didn't know before:
Basically, when plants are growing, photosynthesis is happening in their cells. And that photosynthesis gives off a very specific wavelength of light. The OCO instruments in space measure that light all over the planet.
"NASA and others have turned this happy accident into an incredibly valuable set of maps of plant photosynthesis around the world," explains Scott Denning, a longtime climate scientist at Colorado State University who worked on the OCO missions and is now retired. "Lo and behold, we also get these lovely, high resolution maps of plant growth," he says. "And that's useful to farmers, useful to rangeland and grazing and drought monitoring and forest mapping and all kinds of things, in addition to the CO2 measurements."
