I just noticed that Larry Solum, an eminent and highly-regarded contemporary legal scholar, recently shouted out my forthcoming paper “Coase’s Parable” on his influential Legal Theory Blog: see here or below. Although some (but not all!) of my previous work (see here, for example) has been featured on Professor Solum’s scholarly blog before, this is the first time that one of my papers was stamped “Highly Recommended“. Suffice it to say I am super-elated for this recognition, especially coming from Professor Solum! Now, back to grading …
Alternate title: Review of Joe Lancaster’s “Who owns the satellites orbiting the Earth?”
Hello again! I am still reviewing several new essays about outer space that were published in the December 2022 issue of Reason magazine. Today, I will review “Who owns the satellites orbiting the Earth?” by Joe Lancaster, an assistant editor at Reason.
Although this particular piece is one of the shortest in this collection of outer space essays, Mr Lancaster’s report is very informative and should be read first because it surveys the main types of spacecraft that orbit the Earth today. To the point, Lancaster identifies four different categories of man-made satellite systems: state-owned satellites, geostationary and non-geostationary satellites, and Earth-observation satellites. But how many spacecraft overall are in outer space right now? Building on Mr Lancaster’s report, I will try to tabulate a rough census, so to speak, of the satellite population in each category and add the following observations as follows:
1. Satellites in non-geostationary orbit
By way of background, non-geostationary satellites can be launched into two different orbits: Low-Earth Orbit (LEO), altitudes that are generally between 200 to 2,000 kilometres above the Earth, or Medium-Earth Orbit (MEO), altitudes between 8,000 and 20,000 kilometres–and this category is by far the largest one: there are literally thousands of small non-geostationary satellites in outer space right now. (For reference, check out this survey of non-geostationary satellite systems via ArXiv.) It’s also worth noting that, since these satellites move across the sky during their orbit around the Earth, a fleet of small satellites (called “constellations”) is required to provide continuous communications coverage on Earth.
Among other things, I learned from Lancaster that the largest player in this category is Starlink, which is owned by SpaceX. As of August 2022, for example, SpaceX had launched over 3,000 Starlink satellites in orbit. According to Lancaster, the Federal Communications Commission has decided that SpaceX cannot have more than 12,000 in operation at any one time, but the company hopes to raise this cap to 42,000! (In addition, Lancaster notes that Amazon plans to launch more than 3,200 broadband satellites into non-geostationary orbit. For more information, see Amazon’s Project Kuiper.)
2. Satellites in geostationary orbit
By contrast, satellites in geostationary orbit appear fixed in the sky when observed from the ground because they orbit the Earth at the same speed the planet rotates. (Also, their orbits are the furthest from us: 35,786 kilometres above the Earth to be exact.) I learned from Lancaster that two of the earliest private sector pioneers in this category are DirecTV and Dish Network. DirecTV, for example, maintains a fleet of over a dozen geostationary satellites suspended over 22,000 miles from the Earth, while Dish Network operates 11 such satellites. Other players include Intelsat, which began as a government-owned enterprise and recently emerged from bankruptcy protection, and Viasat, which operates five geostationary satellites, providing home Internet and in-flight Wi-Fi.
3. Earth-observation satellites
Most Earth-observation satellites are in low-Earth orbit (see item #1 above) and are used for both military and civilian purposes: spying, meteorology, cartography, etc. (see here, for example). According to this 2021 report, there are some 950 Earth-observation satellites in all, with the largest number belonging to two U.S.-based companies: Planet Labs and Spire Global. (Combined, Planet Labs and Spire Global own and operate over 300 Earth observation satellites!) For his part, Lancaster singles out Maxar Technologies, which owns more than 80 of the Earth-observation satellites currently in orbit. (As an aside, the data generated by Maxar’s satellites was used to create Apple Maps.) In addition, Lancaster also mentions Capella Space, which launched two Earth-observation satellites in January 2021. Their spacecraft collect topographical data from all over the world, multiple times per day, and provide 24-hour all-weather Earth observation.
4. State-owned satellites
Lancaster actually begins his survey with “State operators” because state-owned satellites, which are used for spying, map-making, and climate research, still comprise a large fraction of the total number of Earth-observation satellites in orbit today. (According to this 2021 report, for example, the Chinese Ministry of National Defense owns 71 such satellites, while the U.S. National Reconnaissance Office owns 39. By comparison, Russia’s Ministry of Defense owns 19 satellites, and India’s Space Research Organization owns 17.) I, however, prefer to conclude with this category because state-owned spacecraft appear to comprise a smaller and smaller portion of the overall population of satellites.
Where should the center of the world be located? I posted this circa-1947 map on my blog on Pearl Harbor Remembrance Day 2017 (see here) and again in 2020 (here). It’s one of my favorite maps so I am posting it again this year to mark this somber occasion. Also, here is a direct link to the map.
Alternate title: Review of Eric Berger’s “We are going to the Moon”
As I mentioned in a previous post, this week I am reviewing several new essays on the theme of outer space published in the December 2022 issue of Reason magazine. Today, I will review the longest essay in this special collection: Eric Berger’s piece “We are going to the Moon”.
The Good. The best part of this essay is its overview of the commercial space industry as well as its brief history of SpaceX’s success. (Among other things, Mr Berger is the author of the excellent book Liftoff, which describes the meteoric rise of SpaceX from a struggling startup to a major player in the commercial space industry, so he is a credible source.)
The Bad. Toward the middle of his essay, Berger cites a group of unnamed lunar advocates (most likely lobbyists for traditional space contractors) who claim that “NASA has unfinished business on the moon and that the agency should return there on a sustained basis–not just for flags and footprints, but for eventual settlement.” Really? What about the risk-reward tradeoffs? Alas, Berger never explains why we should send men back to the moon; i.e. he never makes a positive case for doing what has already been done.
The Ugly. When discussing NASA’s new Artemis program toward the end of his essay, Mr Berger defends Artemis instead of calling it out for what it is: a costly and unsustainable space age boondoggle costing over $4 billion per launch! (See here, for example.) Given his ample knowledge of the advantages of reusable booster rockets and of the wasteful methods of traditional space contractors, who “have strong incentives to protect a status quo that benefits their bottom lines through long-term cost-plus contracts”, Mr Berger should know better!
On this day (6 December) in 1865, the Thirteenth Amendment was officially ratified by the requisite number of States (two-thirds) when Georgia became the 27th State to approve this historic amendment out of 36 States in the union at that time. The remaining nine States to ratify the 13th did so as follows: Oregon (8 December 1865), California (19 December 1865), Florida (28 December 1865), Iowa (15 January 1866), New Jersey (23 January 1866–after rejection on 16 March 1865), Texas (18 February 1870), and Delaware (12 February 1901–after rejection on 8 February 1865). That’s only seven States, however. The last two holdouts were Kentucky (18March 1976(!!!)–after rejection on 24 February 1865) and Mississippi (16 March 1995(!!!!!!)–after rejection on 5 December 1865).
Alternative title: Review of Payton Alexander’s “The FCC: America’s Other Space Agency”
A few days ago (see here), I mentioned that Reason magazine just published a collection of essays regarding various aspects of space exploration in its December 2022 issue. Here, I will review one of the best essays in this issue: Payton Alexander’s piece, which is titled “The FCC: America’s Other Space Agency”.
When you think of outer space, you might think of NASA, but Mr Alexander, an attorney in Washington, D.C. who represents space and satellite clients, notes that it is the Federal Communications Commission (FCC), and not NASA, that “has effectively become [the] primary space regulator” of the U.S. commercial space industry. Although the FCC was established by Congress in 1934 to regulate wire and radio communications, this expansion of the FCC’s jurisdiction into outer space is based on the fact that satellites are like flying radio antennas, or in the eloquent words of Mr Alexander: “If you’re putting anything in space–be it a communications satellite, a weather satellite, even a human being–you’re going to be communicating with it.”
Among other things, the FCC “parcels out orbital altitudes to ensure that constellations of satellites in non-geostationary orbit do not collide or cause interference with each other.” The FCC allocates these orbits not only to prevent satellites from bumping into one another, but also to avoid signal interference in outer space. As a result, if you want to launch a satellite into orbit from the United States, you must first obtain a special license from the FCC. So, what criteria does the FCC use to grant or deny these launch licenses? More to the point, why doesn’t the FCC conduct “orbit auctions”, i.e. why doesn’t the FCC sell orbits to the highest bidder, something I suggested on this blog on many occasions (see here, for example)?
To his credit, Mr Alexander appears to be receptive to this idea! He mentions Ronald Coase’s landmark 1959 article “The Federal Communications Commission“. As Mr Alexander correctly notes, Professor Coase’s 1959 article planted the seeds “for a revolution that would transform telecom policy in the U.S. and around the world.” Specifically, when Coase wrote his 1959 article, the FCC allocated radio and TV frequencies by holding formal hearings or “beauty contests”, a costly and totally subjective proceeding in which competing applicants would explain how their proposed uses of a given frequency would “serve the public interest”, a vague and indeterminate standard.
Coase’s FCC article, however, proposed a different method for allocating frequencies: markets. In the words of Mr Alexander:
“The FCC, Coase suggested, should hold out a section of the electromagnetic spectrum, divided into chunks of a few megahertz each, and accept bids from interested parties who sought to use it to provide service. Bids would be evaluated almost entirely in terms of dollar value, with less attention paid to the merits of this or that proposed business plan. The primary purpose of the auction paradigm would not be to raise money. The point would be to put skin in the game and gauge the value of the business a prospective operator envisioned. Coase reasoned that an entrepreneur would be unlikely to bid $1 billion for a few megahertz of spectrum unless she were confident her returns would be even greater. And if she came up short, she’d be left holding the bag, a calculation similar in some ways to that of an entrepreneur seeking a loan to start a business.
“The article became one of the most influential economics papers of the last century. But for decades, hardly anyone listened to Coase. When he testified to the commission, Commissioner John S. Cross asked, “Are you spoofing us? Is this all a big joke?” Much later, when Washington abounded with proposals to liberalize, marketize, and privatize, officials paid more attention. Thirty-four years after the publication of Coase’s article, the Omnibus Budget Reconciliation Act of 1993 authorized the FCC to conduct its first spectrum auction. Since then, more than 100 auctions have been held … [and] have brought in over $200 billion for the Treasury ….”
Although Mr Alexander doesn’t call for orbit auctions outright (much to my chagrin, I might add), as I explained in this 13 December 2021 blog post, the logic of Coase’s argument extends to outer space. After all, as Mr Alexander himself notes, the vast majority of American launches are conducted by private providers for private customers. So, why not allow these private firms to bid for the right to launch their satellites into outer space? Just a thought …(Note: I will review Eric Berger’s “We Are Going to the Moon” essay next.)
The beautiful city of Santa Barbara in California, where I went to college, takes its name from Saint Barbara, the patron saint of armourers, artillerymen, architects, mathematicians, miners, and the Italian Navy, and today (4 December) is her feast day. (In Spanish, this day is la fiesta patronal en honor de Santa Bárbara.) Among other things, according to this account of Saint Barbara’s life, she was known for her beauty but never married:
“Barbara was born in the mid third century in Heliopolis, Phoenicia [the city of Baalbek in modern-day Lebanon, which is now a UNESCO World Heritage Site; see here] to her rich pagan father Dioscorus. Barbara was really beautiful and her father, in order to preserve her beauty and protect her from the world, locked her up in a very high tower. A case very similar to the fictional story Rapunzel. He only allowed her pagan teachers to see her. *** As a result of her extreme beauty, many men got to hear about her, and suitors from far and near came to seek her hand in marriage. Her father too kept mounting pressure on her to accept one of these suitors. Barbara declined them all and when she could no longer bear the pressure from her father, she asked him to stop pressurizing her into marriage as that could only bring a strain on their relationship.”
How much of this account is fiction and how much fact? Either way, as someone who loves mathematics (I have published several papers on game theory, a branch of mathematics) and who went to college at UCSB, I consider Saint Barbara as my patron saint! Below are four depictions of Barbara via Google Images:
Merry Christmas! Reason magazine just published a fascinating and thought-provoking collection essays on various aspects of space exploration in its December 2022 issue (see here), the cover of which is pictured below. The five essays that most caught my attention were as follows (in alphabetical order, by author):
For my part, I have previously proposed “launch auctions” to allocate orbits in outer space (see here, for example), and I am currently researching this idea further. In the meantime, I will write up short reviews of these excellent essays next week.
Thus far, we have identified and responded to three possible objections to Hayek’s conception of knowledge. Among other things, we have explored the “social construction” of knowledge (see here) and the “commodification” of knowledge (here), but we have not yet defined what we mean by “knowledge”. Here, I will conclude this series by presenting a specific conception of knowledge: knowledge as belief.
Where should we draw the line between knowledge and belief, between objective and subjective truth, and why does this distinction matter? (As an aside, philosophers, going back to Plato, have debated the knowledge-belief distinction for centuries; for reference, here is a helpful summary of the difference between knowledge and belief.) However this line is drawn, unless you are a Platonist knowledge is not always about truth or some Platonic ideal; sometimes knowledge is based on one’s beliefs, i.e. what one believes to be true, and beliefs (unlike absolute truths) are always tentative. Moreover, this “belief conception of knowledge” has radical implications for Hayek’s defense of the price system. In fact, it totally undermines Hayek’s argument! Let me explain:
For Hayek, prices reflect hidden information–information that is spread out over many dispersed individuals. But what if the price of an asset is based on people’s beliefs? In that case, if the price of an asset merely reflects the aggregate beliefs of people about what they think that good is worth, then the price of a particular asset may or may not reflect its true underlying value but rather what people think the asset is worth. So what? The problem here is that people might be basing their estimate of an asset’s value on what they think other people think the asset worth, and if those other people are doing the same, then we will find ourselves in an infinite loop or regress!
This is the “Keynesian beauty contest” or “beliefs about beliefs” problem that I have blogged about before (see here and here, for example), and to my mind, this potential infinite regress poses the most serious challenge–not only to my proposed “truth market” idea but also to Hayek’s defense of markets more generally. For now, I just want to shout out my colleague and friend David Schraub, who first brought this problem to my attention last month when I presented my truth market idea at a colloquium. (See also his thoughtful comments to my 17 November 2022 blog post (here).) Suffice it to say that this problem is a potentially devastating one to Hayek and me, so I promise to reflect further on David’s comments and respond soon …
