    And this is exactly why _they_ don't want NASA pointing back to Earth... And why they want them to only have enough funding for the megaprojects that redirect federal money into red states.

    "There's nothing to see here! Move along!"

    But really, I'm glad they managed to get this out there despite the political shenanigans. It looks like they manage their own shenanigans by providing information / assistance, while not actually doing the leg work on building it or deploying it...

    It will help to eventually find the hotspots (which, if in the US, are likely businesses skirting laws for profit... Or poor monitoring by the business). In either case, we can have more information on where to act.

      I see where you’re coming from, but the reality is not as stark as you have put it. The forces you point to are real, but it’s more complex because many people have seen the value in learning about Earth.

      A huge reason we have a NASA Earth observing system (and not just weather satellites) is the studies that grew out of the CFC damage to the ozone layer [1]. Ground stations and aircraft and balloons turned out not to be enough to assess it, so the measurements moved to space and use spectroscopy now.

      (The current fleet: https://science.nasa.gov/earth-science/missions/)

      This has led to comprehensive CO2 observation from space, and sea surface temperature, and many other climate-related measurements including methane. All this goes back many decades at this point. It’s not a few people who managed to launch one satellite!

      [1] For short, https://en.wikipedia.org/wiki/Earth_Observing_System#History..., but see also: https://muse.jhu.edu/book/3472

      It’s likely that countries will get CO2 satellites to point fingers at each other. Ending up with everyone monitoring everyone. Also, CO2 import taxes will be introduced to protect local industries like steel, fertiliser, and cement.

      For businesses it is actually in the best interest to get clarity on the rules early on. If they stay behind on technology to reduce emissions, they might eventually lose out.

      What specifically are the “political shenanigans”? Do you have any evidence/links?

      I personally don’t think studying earth is really what I want out of NASA. I would expect that funding to go towards study of space. For Earth, I would view that as more the job of the EPA or some other agency, and think it’s more appropriate for them to set aside funds for a satellite or whatever they need.

      But yes it’s interesting to see where there are unexpected plumes. I suspect a lot of those are in third world countries where regulations and rule of law is worse, and it may be hard to address those effectively (except by subsidizing them). Sure there are some examples in the US, but the ones in the article seem much smaller in magnitude.

        You are getting a well-deserved correction to your ignorance of political forces that might result from perceived threats to the oil and gas industry.

        I want to comment on a separate thing, about responsibility for the measurement, that’s in your second paragraph.

        Developing the spectroscopic measurement of methane from space took a lot of time and engineering skill. (I happened to observe some of this work as part of $dayjob.) In the US, the responsibility for developing novel space measurement technology has historically gone to NASA.

        It is proven in space (raised to “TRL 9” in the jargon) by NASA, and then transitioned to other sectors, like NOAA or USGS, for operational use. The prioritization and maturation is very well developed at this point.

        Part of the reason it rests with NASA is that systems for spectroscopic measurement of gases (in this example) are also used for other space missions, e.g. planetary and astrophysics. For instance, some of the team of this methane instrument overlaps with the MISE team that will use spectroscopy for Europa https://europa.nasa.gov/spacecraft/instruments/mise/). Besides sharing personnel and knowledge, I believe some of the sensor hardware for MISE and for that in OP was fabricated at the same facility.

          What I am getting from your comment is an ad hominem attack just because I asked for evidence around claims that I can only assume were false. Instead of admitting they were false, you’re calling me “ignorant”. Nice.

          • cwalv 11 hours ago ago

            Nothing wrong with ignorance .. asking for a source, as you did, is implicitly saying you recognize that you may be ignorant. The only shameful ignorance is ignorance of ignorance.

            That said, I assumed the "You are getting a well-deserved correction" part you're replying to had a typo, or was referring to some other post. I didn't parse it the same way. To me, if a correction of ignorance is "well deserved," that's a vague compliment.

            • bloomingeek 10 hours ago ago

              When someone points to an area of my ignorance, I research the hell out of it to become educated on the matter. If I were to become offended by this being pointed out, I would have succumbed to stupidity.

      • dylan604 16 hours ago ago

        Depending on who wins the election, but one party has made publicly known that they will specifically defund or worse the agencies that will report this kind of information. What other examples of political shenanigans do you need? The same party that when they were in office removed the ability of these same agencies from making these type of releases to the point that they created "rogue" social media accounts.

        • blackeyeblitzar 15 hours ago ago

          > one party has made publicly known that they will specifically defund or worse the agencies that will report this kind of information

          Evidence on the specific claim you’re making? Defunding government agencies for savings or efficiency is not the same as trying to defund things specifically to hide certain scientific data with some sinister goal.

          > What other examples of political shenanigans do you need?

          I’m looking for evidence that supports the GP’s claim. Are there political acts that redirected money from NASA into red states, with an intent to funnel funding based on that political leaning? Is there evidence that they tried (and succeeded?) interfering with specific projects on the grounds that it would show pollution sources that are politically problematic (as opposed to simply defining NASA’s mission as studying things outside of earth)?

          • defrost 15 hours ago ago

            The US has been through exactly this before:

            (2016):

                 On space issues, a senior Trump advisor, former Pennsylvania Rep. Bob Walker, has called for ending NASA earth science research, including work related to climate change. Walker contends that NASA’s proper role is deep-space research and exploration, not “politically correct environmental monitoring.”
            
            ~ https://theconversation.com/eyes-in-the-sky-cutting-nasa-ear...

            (2018) Trump White House quietly cancels NASA research verifying greenhouse gas cuts

            ~ https://www.science.org/content/article/trump-white-house-qu...

            And, again, NASA's mission is assisted by testing instrument designs from space on the only planet we have complete surface access to .. otherwise it's just diddling about with remote guesswork sans ground truthing.

            • startupsfail 14 hours ago ago

              The tragedy of MAGA is that this is the tragedy of the commons in an adversarial setting, where some members are actively trying to destroy the commons to gain political power. Add to that foreign power interference to finance helpful idiots and it’s not surprising that even obvious common goods, like triaging where accidental greenhouse gas leakage happens are treated adversely.

              • dylan604 14 hours ago ago

                I imagine the foreign agencies running these interference campaigns as caricatures sipping champagne/cognac/etc, cigar smoking, fully belly laughing that is occurring in all of these places at how little effort is being expelled on their part causing so much chaos on our part.

          • dylan604 15 hours ago ago

            https://en.wikipedia.org/wiki/Project_2025

            Just defunding agencies from reporting science is bad enough regardless of where they move the money. Denying the part because it's not the whole of what you're looking for says more about you than anything else.

        Space itself is pretty dull .. it's mostly a near perfect vacuum after all.

        Planets and stars, galaxies and clusters are more interesting.

        How does NASA perfect the remote scanning of a planet from an orbital platform if not working out the designs close to home first?

        The EPA provides ground-truthing, surface level observations across the planet, these are used to calibrate and test results from orbiting instrument packages with more challenging transfer functions ( the path from what an instrument actually produces to an interpretation of what that signal "means" ).

      • HankB99 16 hours ago ago

        Funding from "Carbon Mapper, a new nonprofit organization, and its partners – the State of California, NASA’s Jet Propulsion Laboratory (NASA JPL), Planet, the University of Arizona, Arizona State University (ASU), High Tide Foundation and RMI"

        From https://carbonmapper.org/articles/carbon-mapper-launches-sat...

        I don't know enough about the EPA's charter to know if this would be within their realm or not. Certainly launching and managing satellites is within the purview of NASA.

  • noiv 15 hours ago ago

    Here's the interactive map with nearly 6.5k plumes detected: https://data.carbonmapper.org/#1.04/31.9/19.2

  • ajoseps an hour ago ago

    It will be interesting to take the data and normalize it by population density. It won’t be a perfect metric since I’m guessing a lot of these plumes will have their source material sourced from elsewhere e.g. landfills, recycling centers, manufacturing

  • tagami 11 hours ago ago

    The project is funded by 501(c)(3) non-profit Carbon Mapper. Tanager-1 was built by Public Benefit Corp and publicly traded Planet Labs. I understand that the funding raised from the non-profit paid for the licensing of the technology developed at JPL, NASA's only federally funded R&D center managed by CalTech.

  • Sandbag5802 16 hours ago ago

    I wonder with this data, it'll push communities to do something about these plumes if they are close to their home.

  • leptons 16 hours ago ago

    Wow, Texas.

    But, I'm not sure if the data is complete across the globe yet. There doesn't seem to be much data over China yet.

    • dylan604 16 hours ago ago

      And even if there were data from China, there's very little that could be done about it. It's not like the US could shame the plank in their eye.

      • mturmon 15 hours ago ago

        One goal is to do a fine grained global census, just to see what we are confronting:

        https://acp.copernicus.org/articles/22/9617/2022/

        Previously, a high quality census was done of California and it turned up a nice separation into source categories (e.g., oil/gas extraction, gas transport, dairies, landfills):

        https://www.nature.com/articles/s41586-019-1720-3

        This was very impactful and influenced legislation and further measurement.

        The lead author is the CEO of the nonprofit that coordinated launch of this satellite. He’s been involved in the fundamentals of this measurement for many years, including his time as a lead system engineer at JPL.

      • throwup238 16 hours ago ago

        Just because we can’t do anything about it doesn’t mean that China won’t. They haven’t been completely unresponsive to internal pressure on air pollution and armed with public data, the government might want to take action. Most countries in the world don’t have the resources to run these kinds of satellites anyway so they depend on NASA/ESA to make this kind of data available to decision makers.

        • dylan604 16 hours ago ago

          It would make much more sense for the country that NASA is part of to use the data to make changes within itself. Let's focus on the changes we can control not the changes we wish others to make. The problem is that within the US this is believed to be junk science, fake news, and whatever other nonsense labels used.

          • mturmon 15 hours ago ago

            Why not both?

            That is, a global measurement and a regional measurement? (Regional, with airborne and in situ for validation of the large scale measurement.)

            And appropriate global and regional studies? They are highly synergistic! Maybe something integrated like:

            https://above.nasa.gov/about.html?#questions

            • dylan604 14 hours ago ago

              > Why not both?

              Without the "moral high ground", there's no way anyone would listen to someone pulling a "pot calling the kettle black", "do as I say not as a I do", or whatever other phrase you like. Attempting to influence someone like that does nothing positive for your image

          • mistrial9 15 hours ago ago

            not very many years ago, the public news in the USA said flatly that climate change was a "hoax" to "get money".. some people still say things like that in public. Meanwhile, the clock is obviously and plainly ticking into irreversible changes.

            Throw any and all science information into the public now and see what sticks IMHO

      • akamaka 12 hours ago ago

        They certainly can do something about methane emissions in other countries, such as this proposal (which is similar to the EU carbon adjustment which came into force this year):

      • ordu 14 hours ago ago

        I think this is unfair. China is leading the transition to green energy, China does a lot. The data from the satellite is useful for China also, and China can benefit from it, because it means that China doesn't need to launch their own monitoring satellite. And if USA politely point to China that China missed something, I'm sure China will do something about it. Not instantly, and probably with impolite responses like "get off my lawn" like they like, but still China will hear.

  • nascamallai 12 hours ago ago

    Here's an approximately 1,000,000-lb plume of the most significant greenhouse gas in the atmosphere: a typical cumulus cloud.

    Nothing anthropogenic comes remotely close; which fact makes this NASA-designed instrument a waste of time.

    • _moof 12 hours ago ago

      Water vapor, which contributes between 41% and 67% of the Earth's greenhouse effect, has been part of the atmosphere since Earth first formed. Liquid water - clouds - contributes between 25% and 31%, and has likewise been part of the atmosphere since before the existence of humans. In other words, the effect of atmospheric water has had billions of years to reach equilibrium. Atmospheric water, at a global scale, is also not significantly affected by human activity.

      The remainder of the greenhouse effect is caused by gases like CO2 and methane, which are affected by human activity. They contribute significantly - CO2 is a mere 0.04% of the atmosphere but is responsible for between 18% and 26% of the Earth's greenhouse effect, methane 6% - and we have significantly altered the concentration of these gases since the Industrial Revolution. The amount of CO2 has nearly doubled, and the amount of methane has more than doubled.

      So no, this mission is not a waste of time.

    • throwaway4220 12 hours ago ago

      (Ignoring obvious denialism here)

      Knowing where methane is literally pouring out for the taking is useful if you want to burn it for energy.
