NASA Opposes Lithium Mining at Nevada Desert Site Used to Calibrate Satellites (apnews.com) 87

An ancient Nevada lakebed could become a vast source of the lithium used in electric car batteries, reports the Associated Press. But "NASA says the same site — flat as a tabletop and undisturbed like none other in the Western Hemisphere — is indispensable for calibrating the razor-sharp measurements of hundreds of satellites orbiting overhead." At the space agency's request, the U.S. Bureau of Land Management has agreed to withdraw 36 square miles (92 square kilometers) of the eastern Nevada terrain from its inventory of federal lands open to potential mineral exploration and mining. NASA says the long, flat piece of land above the untapped lithium deposit in Nevada's Railroad Valley has been used for nearly three decades to get measurements just right to keep satellites and their applications functioning properly. "No other location in the United States is suitable for this purpose," the Bureau of Land Management concluded in April after receiving NASA's input on the tract 250 miles (400 kilometers) northeast of Las Vegas...

In Railroad Valley, satellite calculations are critical to gathering information beamed from space with widespread applications from weather forecasting to national security, agricultural outlooks and natural disasters, according to NASA, which said the satellites "provide vital and often time-critical information touching every aspect of life on Earth." That increasingly includes certifying measurements related to climate change. Thus the Nevada desert paradox, critics say. Although lithium is the main ingredient in batteries for electric vehicles key to reducing greenhouse gases, in this case the metal is buried beneath land NASA says must remain undisturbed to certify the accuracy of satellites monitoring Earth's warming atmosphere...

The area's unchanged nature has allowed NASA to establish a long record of images of the undisturbed topography to assist precise measurement of distances using the travel time of radio signals and assure "absolute radiometric calibration" of sensors on board satellites. "Activities that stand to disrupt the surface integrity of Railroad Valley would risk making the site unusable," Jeremy Eggers, a spokesman for NASA's Goddard Space Flight Center in Greenbelt, Maryland, told The Associated Press.

One company with most of the mining rights says the tract's withdrawal will put more than half the site's value out of reach, according to the article.

But the Associated Press got a supportive quote for the move from the satellite imaging company Planet Labs, which has relied on NASA's site to calibrate more than 250 of its satellites since 2016. "As our nation becomes ever more impacted by an evolving and changing environment, it is critical to have reliable and accurate data and imagery of our planet."

            Extracting and refining Lithium from the sea will require far more energy in the first place, because of its very low concentration, meaning the negative externalities of that process will unfortunately be far greater.

            There are some development like that one for instance [sciencedirect.com] (oh look, China leading research on that field too), but when you scratch beneath the surface, we have no idea how to scale the proposed solutions. Most of them make use of rare minerals, that are themselves under tension.

            • Energy requirement isn't the issue. Energy can be greenly generated. There's no way to strip mine land non destructively. Additionally heavy machinery used for mining is not easily electrified. Evaporation ponds may use more energy, but the have a lower ecological footprint and can be setup to barely have a carbon footprint at all.

              • But externalities can be factored in relatively easily, especially for a known quantity like a lithium mine. We've had lithium mines, we know how much it costs to clean them up, and we can build-in cleanup costs into the land lease or license the mining company needs. This would be a fantastic incentive, as well. They can put the cleanup money into escrow and, if they can manage to *not* pollute, they can get that money back when they close the mine.

                • Except that we have to take into account larger economic and societal externalities as well, which you can't get simply by looking at this particular salt flat as a lithium mine in potentia. Clearly, there is a very large economic benefit to having a satellite calibration site, and by devoting the salt flat to that purpose rather than a lithium mine, society benefits even if a particular lithium extraction company doesn't.

            Mining salt from dry deposits is far less energy intensive than extracting it from the ocean. Doing it by simple/solar evaporation requires huge tracts of land, and boiling the water off to do it artificially requires enormous amounts of energy.

            • Energy is not an issue as it can be generated greenly. You can't strip-mine a land greenly. So while evaporative extraction has a higher energy intensity it does not follow that it has a higher carbon intensity, and it definitely doesn't have as high of an ecological footprint.

        Its certainly true that from a density to weight standpoint its going to be tough to come up with a chemistry and design that does not use lithium while meeting or exceeding the current state-of-the-art around optimizing for these properties. However there are possible ways to get there. Other chemistries offer better or at least more flexible thermal envelopes such that weight savings might be achieved in the overall design of the batter cell.

        Its also true the li batteries are used in a lot of not-weight-critical applications today because of density/capacity/charge time/durability that might be met other ways. Who cares how much your power wall weights?

The problem is that there is no magic involved, all of them have disadvantages, the main being, as you say, that the batteries made with those alternatives are (a lot) heavier, and take more space for the same capacity.

          Why would it necessarily need to be both slower _and_ have shorter range? While the engineers designing it might trade off some speed and some range, they don't have to. They could focus entirely on just having shorter range, or on having lower speed. Or, in fact, with some of the other possible chemistries, they don't have to trade off speed _or_ range. They could use a metal air battery that has a higher specific energy than a lithium-ion battery. There are still some tradeoffs, but they're different ones

As global warming is a global phenomenon, show us that you are a champion of the health and wellbeing of the global population, and not just your constituants who happen to include the businesses holding mineral rights in the area affected by the BLM decision.

As there are likely other places to mine lithium (or for that matter other minerals that are or may be useful in implementing technologies that reduce or even turn back the effects of climate change) within the US, I agree that the uniqueness of this land for the purpose NASA uses it should be given priority over other uses.

    To both legislator(s) and businesses opposing this move, I trot out one of my favorite quotes from a Heinlein work (The Past Through Tomorrow, 1967):

    "There has grown up in the minds of certain groups in this country the notion that because a man or corporation has made a profit out of the public for a number of years, the government and the courts are charged with the duty of guaranteeing such profit in the future, even in the face of changing circumstances and contrary public interest. This strange doctrine is not supported by statute nor common law. Neither individuals nor corporations have any right to come into court and ask that the clock of history be stopped, or turned back, for their private benefit."

    This is an excellent explanation on what absolute radiometric calibration is, how it is done,, and why it is important. It was written in 2020 and is specifically about the Railroad Valley, NV location.

    There's even a deeper technical explanation on the "hows" linked as a whitepaper at the bottom of the article.

      It's a very good article (and a reminder of why /. is worthwhile). Though I didn't see it being written "specifically about the Railroad Valley, NV location" as they mention using calibration tarps as well as other sites around the world. I had to RTFA to determine that the RR Valley location was unique because it represented a calibration source that has been constant over a long time period. Also that it's not just a radiometric calibration source but an altitude calibration source as well.

  • What about in the eastern one? Who cares which hemisphere is used for this...

  • It's not enough to say "Don't do this thing here." You have to provide an alternative that's cost effective. (And cost isn't just measured in money)

      Not in this case, it's just 36 square miles of land, it belongs to the US government and they're choosing not to sell it. You might not like it but it's their property. Yes Lithium is useful, but it's not like this is the only supply there's plenty of lake beds which won't mess up the nations satellites.

      I mean like boo hoo, someone doesn't get to make some money because it will cost the rest of us money. The politicos in this scenario really don't seem to understand how important satellites are to the US ec

    If NASA and satellite companies want it pristine, then they need to establish ownership. Hint - the US government needs the money... ;)

      NASA is a US government agency. The land in question is owned by the US federal government. They already own it.

      • In foregoing the mineral wealth that is present in the land, the US government is depriving their taxpayers of a source of income. Whilst this may be the right thing to do, it is important to recognise that this is cost which is transferring money from US taxpayers to satellite users from around the world. How do we decide and who decides are questions to which the theoretical answer is the US Congress... cue giggling...

    EVERY Democrat administration of the past 60 years has used various agencies of the federal government as cover for environmental policies, asserting claims that this or that narrow vital interest requires that another swath of land be taken off the list of land available for drilling, mining, logging or other activities. The Clinton administration famously used wild horses and owls for these purposes.

    To be clear: I am not asserting that either [a] there is no value in satellite calibration or [b] that Republican administrations do not similarly abuse the bloated federal regulatory machine for other agendas, THIS article, however, is about a Democrat admin using the satellite calibration canard.

    There's NOTHING about any patch of land that makes it better as a calibration target for remote imagery than very well-defined, man-made, precisely positioned targets. NASA could jolly well design and create targets at Edwards, KSC, etc. The simple truth is that satellite image sensors are now so good and with such high resolution that large targets are no longer needed, except as a fig leaf for political choices. I will admit that my direct personal experience does not include satellite imagery, but I have worked on high altitude sensors, and there are simply no actual unknowns in these technologies anymore. We can build sensors on the ground, calibrate them on the ground, fly them, and verify their performance by targeting ANY known ground target (and see that, actually this is more of a verification than a calibration).

  • Did NASA ask Nevada if they could use the Railroad Valley for this?

    What if NASA had used the surface parking lot at Disneyland? Would that prevent Disney from erecting parking structures, thus freeing up space for California Adventure Park?

    What if they used Mission Beach in San Diego. Would that prevent Big Olaf's ice cream stand from being repainted? FBI: "Put down that paint brush! NASA's orders!"

There are never any bugs you haven't found yet.
