Carbon Mapper Spots First Methane Plumes From Tanager-1

The first data from Planet’s hyperspectral Tanager-1 spacecraft has revealed plumes of invisible, climate-altering gas, the non-profit that financed its development said. 

Carbon Mapper is developing a global methane monitoring service to track a major contributor to climate change. By spotting leaks and sharing the data, the organization hopes regulators and businesses will be able to work together to reduce emissions, and researchers can better understand how methane affects the planet.

PPP? You know me: The organization raised $130M to facilitate a public-private partnership between NASA JPL and Planet that transferred spectrometer technology from the government to the private sector—something that wouldn’t have been possible just a decade ago.

“Carbon Mapper has a public good mission to make the methane data available, and Planet as a public benefit corporation is aligned with that,” Carbon Mapper CEO Riley Duren, a former JPL engineer, told Payload. “They also want to be able to develop commercial revenue, and we want that because we’re looking to that commercial revenue to enable Planet to build out the constellation so that this isn’t something that philanthropy is funding forever.”

Pull it down: The new sensor detects 400 spectral bands, compared to the three that your eyes can see, or the eight tracked by sensors on Planet’s SuperDove satellites. Robert Green, a JPL researcher who collaborated with Planet, said Tanager-1’s sensor is among the most advanced on orbit.

“The Tanager data cube is a very different beast,” Troy Toman, Planet’s chief product officer, said— and his developers had to build out the infrastructure to downlink, prepare, and deliver that information to Carbon Mapper and, eventually, all kinds of users.

“We’ve kind of been oversubscribed in terms of the early access program, and we’re excited to be able to get that data into more hands,” Toman said. The satellite is still in commissioning mode and needs to be lowered to its operating orbit, a process that won’t be complete until early next year. 

Planet and Carbon Mapper plan to build at least one more Tanager spacecraft, tentatively sometime in 2025, Duren said.
