Carbon-monitoring instrument poised for launch to International Space Station

A $110 million NASA science instrument twice targeted for cancellation by the Trump administration is set for launch Tuesday inside the trunk of a SpaceX Dragon cargo capsule for delivery to the International Space Station, where it will spend three years charting changing carbon dioxide concentrations in Earth’s atmosphere. Once mounted outside the space station’s Kibo lab module, the instrument package will scan the planet between 52 degrees north and 52 degrees south latitude with the sensitivity to measure carbon dioxide levels to a precision better than one part per million, or within about 0.3 to 0.5 percent of the total carbon dioxide present in the atmosphere.
