Launch success! 🚀🛰️
Tanager-2 now joins Tanager-1 in orbit, bringing new visibility into methane super-emitters around the world.
Stay tuned for the satellite’s first look at earth. 👀

The evidence is stacking up 🛰️
New @Stanford research shows that satellites offer accurate, trustworthy #methane data. @planet's Tanager-1 detected 100% of cloud-free releases with no false plumes.
With Tanager-2 in space, our impact will grow. ⬇️ spacenews.com/space-based-me…
🌍 Plumes of the Week
Tanager-1 spotted a large #methane plume in the Permian Basin on Oct. 10. Two days later, Tanager-2 imaged the same source, and we detected methane again.
More satellites with @planet = faster revisits and more data on persistent emitters 🛰️
#MethaneData
Can satellites be trusted to find methane leaks? A blind @Stanford study says yes 🛰️
Researchers staged 481 methane releases in the Arizona desert. Using Tanager-1, Carbon Mapper detected 100% of its cloud-free releases with zero false plumes.

Trustworthy, science-based data turns satellite monitoring into action.
Operators can find and fix leaks fast. Regulators and policymakers can make decisions with confidence.

Tanager-2's first looks at Earth are in. 👀 🌎 And this week's #PlumeOfTheWeek is a big one.
🛰️ Just days after launch, we spotted a large methane plume from a landfill near Spain's coast.
Two Tanager satellites in orbit with @planet means faster revisits & action on emissions.

With Tanager-2 in orbit, California can look for methane leaks at more locations, more often.
Satellite data has already helped fix 18 major leaks in the state, equal to taking ~32,000 cars off the road for a year.

Two birds, one mission 🛰️🛰️
Every thread in our Tanager-2 launch patch tells part of the story—from methane plumes to @planet satellites + the hyperspectral rainbow we use to detect super-emitters. 🌈
Here's what it all means 👇

🚀 IT'S LAUNCH DAY! At 11:18 PT, @Planet's Tanager-2 satellite rides @SpaceX Transporter-18 into orbit, joining Tanager-1 to make methane visible and actionable worldwide. 🌎
📺 Watch live: spacex.com
📋 What to expect: carbonmapper.org/articles/la…
⏰ T-1. @Planet's Tanager-2 launches tomorrow aboard SpaceX Transporter-18.
Since Tanager-1 launched in 2024, visible methane has proven actionable — with mitigation success stories. More to come with 2x the coverage!
Follow along: spacex.com, ~1:18am PT 🛰️
🚀 T-3 days. @planet Tanager-2 satellite launches from Vandenberg SFB, CA.
Since Tanager-1 launched in 2024, our portal has tracked:
✅ 15.2k methane plumes
✅ 5.4k emissions sources
✅ 3.3M kg/hr from super-emitters
Tanager-2 multiplies this. Explore: data.carbonmapper.org
🚀 T-5 days. Tanager-2 launches aboard @SpaceX Transporter-18.
Since @Planet's Tanager-1 launched in 2024, we've proven fixing methane super-emitters drives fast reductions — slowing warming and protecting health.

🌍 #PlumeOfTheWeek
For #ClimateWeekNYC, we highlight a large #methane plume at a landfill in New York State with emissions of ~456 kg/hr. We also detected emissions at this #waste site twice in 2025.
👀 The landfill takes in about 284,502 metric tons of waste a year and was approved to expand in 2018. In July 2025, local news reported an underground fire burning across much of the active site.
💡 Cutting landfill methane could successfully lower New York's emissions, along with co-pollutants that harm public health. The state is considering advanced monitoring in new landfill rules.

🚀 T-6 days. Carbon Mapper's Tanager-2 — built with @planetlabs — launches aboard SpaceX Transporter-18 to track methane super-emitters from space.
It will add to the impact Tanager-1 is already making. 🛰️🔎

Our #ClimateWeekNYC panel focused on how decision-makers are leveraging #methane super-emitter data to accelerate action and reduce some of the largest emissions. 📉 Policy and finance are key levers for mitigation. @OGCInews @SenWhitehouse @aaronaclark1 @cleanaircatf @CDPHE
🌍 Plume of the Week: Carbon Mapper detected a methane plume at a waste-to-energy complex on the outskirts of Hanoi, Vietnam (May 27, 2026). It's the world's 2nd-largest facility of its kind, processing 4,000–5,000 tons/day — about 70% of the city's total waste output. 🧵
Waste that can't be processed here is landfilled instead, which can drive more emissions and odors. Hanoi — part of the C40 climate network — plans to expand the facility to fully process the region's waste as generation grows past 7,600 tons/day.
