The imaginative and prescient
“It doesn’t matter what number of thermographers now we have, boots on the bottom, satellites flying within the air, individuals with drones and airplanes and all the opposite expertise, none of it issues for those who don’t cease methane. None of it counts.”
— Sharon Wilson, “methane hunter” and director of Oilfield Witness
The highlight
Again after I labored with satellites (my profession earlier than journalism), and I’d discuss my job with of us from exterior the area trade, they usually responded merely, “Oh, cool.” It all the time struck me that, although satellites in some ways allow fashionable life, many individuals nonetheless take into consideration area tech when it comes to astronauts and different worlds. However satellites are what make GPS, climate forecasting, long-distance communication, and even airplane Wi-Fi attainable. And a rising fleet of precision satellites are actually enabling local weather options, too: serving to us spot, and cease, air pollution.
Two weeks in the past, a satellite tv for pc designed to determine, measure, and monitor greenhouse gasoline emissions worldwide was launched into orbit by SpaceX. The spacecraft, known as Tanager-1, is a collaboration between NASA’s Jet Propulsion Laboratory, the Earth-imaging firm Planet Labs, the environmental nonprofit Carbon Mapper, and others. Tanager-1 has now joined 23 different satellites on orbit, operated by a mixture of organizations and companies, all able to detecting the potent greenhouse gasoline methane — which, for the primary 20 years after it’s emitted, warms the planet 80 occasions quicker than the identical quantity of CO2.
Naveena Sadasivam and I lately reported on this new wave of methane-monitoring satellites, and as a part of that reporting, we had the possibility to talk with Riley Duren, the CEO of Carbon Mapper. Duren beforehand labored because the chief programs engineer for the Jet Propulsion Laboratory’s Earth science division the place he pushed to determine a local weather analysis portfolio, which included increasing the lab’s capability to observe greenhouse gases. He knew this monitoring might assist mitigate local weather change, not simply examine it.
“You may’t handle what you don’t measure,” Duren stated.
Carbon Mapper itself emerged in 2020 as a “spin-off,” Duren stated, of the work he and others on the lab had been doing to check the sources of methane emissions from planes, determine the worst offenders, and alert them in order that the operators might take motion to repair the leaks that the researchers noticed. Whereas they’d had a lot success with these aerial surveillance campaigns, “to do it in a sustained and operational manner,” Duren stated, “we wanted satellites.”
However authorities companies had no plans to construct and launch satellites of that sort, so Duren began chatting with local weather philanthropists to place collectively the funds that might permit him and Carbon Mapper to create their very own spacecraft.
Tanager-1, and the flock of comparable satellites that Carbon Mapper plans to launch, will work alongside one other nonprofit mission that launched earlier this 12 months, MethaneSAT, to raised perceive the place the highest-value actions will be taken to quell methane emissions and leaks. Duren used a metaphor of photographing birds to explain how the satellites can help one another’s efforts to observe methane. MethaneSAT supplies the equal of a panorama view, and might level out the place there’s a flurry of fowl exercise. Tanager-1 can then zoom in and seize telephoto snapshots of the metaphoric birds and nests. “And since Carbon Mapper’s flying a constellation of satellites,” Duren stated, “it’s form of like a military of birdwatchers which can be going out to observe up on what the panorama photographer has drawn everybody’s consideration to.”
Under is an excerpt of the characteristic I co-wrote with Naveena, overlaying the extremely anticipated launch of MethaneSAT in March, and the hopes and worries of these watching. You’ll find the total characteristic right here, if you wish to learn extra in regards to the historical past of utilizing satellites to observe greenhouse gasoline emissions, what this new fleet provides, and what alternatives researchers hope to open up with this new and improved tech.

Spying from area: How satellites may help determine and rein in a potent local weather pollutant (Excerpt)
On a blustery day in early March, the who’s who of methane analysis gathered at Vandenberg House Drive Base in Santa Barbara, California. Dozens of individuals crammed right into a NASA mission management middle. Others watched from vehicles pulled alongside roads simply exterior the sprawling facility. Many extra adopted a livestream. They got here from throughout the nation to witness the launch of an oven-sized satellite tv for pc able to detecting the potent planet-warming gasoline from area.
The quantity of methane, the first part in pure gasoline, within the ambiance has been rising steadily over the previous few many years, reaching practically thrice as a lot as preindustrial occasions. A few third of methane emissions in the US happen throughout the extraction of fossil fuels because the gasoline seeps from wellheads, pipelines, and different tools. The remainder come from agricultural operations, landfills, coal mining, and different sources. A few of these leaks are giant sufficient to be seen from orbit. Others are miniscule, but contribute to a rising downside.
Figuring out and repairing them is a comparatively easy local weather answer. Methane has a warming potential about 80 occasions increased than carbon dioxide over a 20-year interval, so decreasing its ranges within the ambiance may help curb international temperature rise. And in contrast to different industries the place the expertise to decarbonize remains to be comparatively new, oil and gasoline firms have lengthy had the instruments and know-how to repair these leaks.
MethaneSAT, the gas-detecting system launched in March, is the newest in a rising armada of satellites designed to detect methane. Led by the nonprofit Environmental Protection Fund, or EDF, and greater than six years within the making, the satellite tv for pc has the flexibility to circle the globe 15 occasions a day and monitor areas the place 80 % of the world’s oil and gasoline is produced. Together with different satellites in orbit, it’s anticipated to dramatically change how regulators and watchdogs police the oil and gasoline trade.
“Firms do a very good job of complying with the legislation, however the legislation has been inadequate,” stated Danielle Fugere, president and chief counsel at As You Sow, a nonprofit group that has used shareholder advocacy to push fossil gas producers to sort out local weather change. “So this transformation will enhance incentives for decreasing methane emissions.”
These at Vandenberg or watching on-line had been a bit on edge. Lots might go incorrect. The SpaceX rocket carrying the satellite tv for pc into orbit might explode. Per week earlier than, engineers frightened in regards to the system that holds the $88 million spacecraft in place throughout launch and pushes it into area. “That made us a bit of nervous,” recalled Steven Wofsy, an atmospheric scientist at Harvard College and a key architect of the venture together with Steven Hamburg, the scientist who leads MethaneSAT at EDF. If that didn’t go incorrect, the satellite tv for pc might nonetheless fail to deploy or have issue speaking with its minders on Earth.
They needn’t have frightened. A pair hours after the rocket blasted off, Wofsy, Hamburg, and his colleagues watched on a tv at a lodge about two miles away as their creation was ejected into orbit. It was a jubilant second for members of the workforce, lots of whom had traveled to Vandenberg with their companions, mother and father, and youngsters. “All people spontaneously broke right into a cheer,” Wofsy stated. “You [would’ve] thought that your workforce scored a landing throughout additional time.”
The information the satellite tv for pc generates within the coming months shall be publicly accessible — obtainable for environmental advocates, oil and gasoline firms, and regulators alike. Every has an curiosity within the info MethaneSAT will beam residence. Local weather advocates hope to make use of it to push for extra stringent laws governing methane emissions and to carry negligent operators accountable. Fossil gas firms, lots of which do their very own monitoring, might use the knowledge to pinpoint and restore leaks, avoiding penalties and recouping a useful resource they’ll promote. Regulators might use the info to determine hotspots, develop focused insurance policies, and catch polluters. For the primary time, the Environmental Safety Company is taking steps to have the ability to use third-party knowledge to implement its air high quality laws, growing tips for utilizing the intelligence satellites like MethaneSAT will present. The satellite tv for pc is so necessary to the company’s efforts that EPA Administrator Michael Regan was in Santa Barbara for the launch as was a congressional lawmaker. Activists hailed the satellite tv for pc as a much-needed device to handle local weather change.
“That is going to seriously change the quantity of empirically noticed knowledge that now we have and vastly enhance our understanding of the quantity of methane emissions which can be at present occurring and what must be completed to scale back them,” stated Dakota Raynes, a analysis and coverage supervisor on the environmental nonprofit Earthworks. “I’m hopeful that gaining that understanding goes to assist proceed to shift the narrative in direction of [the] section down of fossil fuels.”
With the satellite tv for pc safely orbiting 370 miles above the Earth’s floor, the mission enters a essential second section. Within the coming months, EDF researchers will calibrate tools and make sure the satellite tv for pc works as deliberate. By subsequent 12 months, it’s anticipated to transmit reams of knowledge from around the globe. Its success will rely upon the standard of the info it may possibly produce and — maybe extra importantly — how that knowledge is put to make use of.

A parting shot
This picture exhibits methane emissions from a landfill in Georgia, detected by Carbon Mapper’s aerial surveillance by airplane (earlier than the launch of Tanager-1, its first satellite tv for pc). These imaging instruments use a spectrometer to disclose the infrared signature the gasoline leaves behind — making the invisible seen.
