Who Owns the Land on Mars?

Nicolas Nelson:

“Who owns the land on Mars? Suppose I go there and [claim the planet by right of conquest or first discovery] and say ‘Hey, I’m selling the whole planet...'"

Sorry, friend, can’t do that.

The Outer Space Treaty of 1967 clearly states that all extraterrestrial real estate “belongs to all mankind” and cannot be claimed as sovereign territory by any nation-state. That kind of sovereign ownership used to be fundamental to any subsequent private ownership claims: the “crown” (or whatever government) had to deed it to you somehow. Nowadays, land ownership can derive from a legal regime, either a nation’s constitution (which inherited “sovereignty” from the old monarchies) or by an international treaty that establishes such a regime … which in this case is exactly what the Outer Space Treaty does.

On the other hand, the OST-1967 does not make private ownership illegal in space or on other planets. Like any good legal regime, the OST-1967 laid a foundation, and later laws passed in nations that are signatories to that treaty have been building upon it. For instance, both Luxembourg and the United States of America have passed laws that clarify property ownership of “space resources,” whether acquired in free-fall (like asteroids, comets, or even the solar flux that photovoltaic panels turn into electricity) or on a planetary surface, or beneath it (like any resources you collect on Mars … or Venus or whatever).

So, as I understand it currently, you can land on Mars and set up your settlement: you own all the stuff you brought with you, but not the land you plopped it onto.

But as your construction bots bulldoze regolith up onto your inflatable dormitory to protect it from radiation, that regolith is now a “resource” that you’ve collected and are using. Now you own that, too.

Your Sabatier-reactors (no radiation, don’t freak out) and your RWGS plant begin sucking in the thin Martian atmosphere and making oxygen, methane, and water out of it. You drill a well down to a geothermally-heated aquifer deep beneath your settlement and use that well to generate electrical power, heat your settlement, do cool science with it (look for microbial life!), and very carefully filter it so you can add it to your water supply: all those “resources” now belong to you.

But you’ve made it complicated now. You have drilled a well and have usage rights to that well… does that give you “water rights” to the giant aquifer you tapped? To some degree? You have built so much stuff on a clearly-delineated area: even though you cannot own it like “real estate,” haven't you established a whole blanket of rights to it just as if you’d homesteaded it or staked a mining claim?

You have a launch and landing pad nearby (not too nearby) with radar telemetry around it: you don’t own the rights to the open air above your launch pad because you own the pad, but you can assert those rights because of the way you use that resource: your future neighbor can’t build a bridge right over your launch pad because it would interfere with your ability to use the improved space resource that belongs to you.

Your rude neighbor could be an idiot and set a fragile inflatable dome next to your launch pad, since you can’t point to a property line and say “behind that, fella”, and since it does not physically interfere with your use of your property. You have the right to go on using your preexisting launch facilities and roast his dome. In that way, it isn't a question of property rights but wisdom versus idiocy.

You can see that once people actually begin “harvesting” and “improving” space resources, property laws will mature pretty quickly. They haven't yet … but the fundamental legal regime is clear: Mars “belongs” to everyone—and therefore, in a practical way, to no one.

How Did 6 Feet Become the Standard Grave Depth?

It all started with the plague: The origins of “six feet under” come from a 1665 outbreak in England. As the disease swept the country, the mayor of London literally laid down the law about how to deal with the bodies to avoid further infections. Among his specifications—made in “Orders Conceived and Published by the Lord Mayor and Aldermen of the City of London, Concerning the Infection of the Plague”—was that “all the graves shall be at least six feet deep.”

The law eventually fell out of favor both in England and its colonies. Modern American burial laws vary from state to state, though many states simply require a minimum of 18 inches of soil on top of the casket or burial vault (or two feet of soil if the body is not enclosed in anything). Given an 18-inch dirt buffer and the height of the average casket (which appears to be approximately 30 inches), a grave as shallow as four feet would be fine.

A typical modern burial involves a body pumped full of chemical preservatives sealed inside a sturdy metal casket, which is itself sealed inside a steel or cement burial vault. It’s less of a hospitable environment for microbes than the grave used to be. For untypical burials, though—where the body isn’t embalmed, a vault isn’t used, or the casket is wood instead of metal or is foregone entirely—even these less strict burial standards provide a measure of safety and comfort. Without any protection, and subjected to a few years of soil erosion, the bones of the dearly departed could inconveniently and unexpectedly surface or get too close to the living, scaring people and acting as disease vectors. The minimum depth helps keep the dead down where they belong.

What's the Difference Between Apple Juice and Apple Cider?

In a time before pumpkin spice went overboard with its marketing, people associated fall with fresh apples. Crisp and fresh, they practically beg to be crushed and pulped into liquid. But what’s the difference between apple juice and apple cider?

According to the state of Massachusetts, home to a variety of apple-picking destinations, both apple juice and apple cider are fruit beverages. But apple cider is raw, unfiltered juice—the pulp and sediment are intact. To make cider, the apples are ground into an applesauce-like consistency, then wrapped in cloth. A machine squeezes the layers and strains out the juice into cold tanks. That’s the cider that ends up on store shelves.

Apple juice, on the other hand, takes things a step further—removing solids and pasteurizing the liquid to lengthen its shelf life. It’s typically sweeter, possibly with added sugar, and may lack the stronger flavor of its relatively unprocessed counterpart. It’s also often lighter in color, since the remaining sediment of cider can give it a cloudy appearance.

But that’s just the Massachusetts standard. Each state allows for a slight variation in what companies are allowed to call apple cider versus apple juice. The cider may be pasteurized, or the cider and juice may actually be more or less identical. One company, Martinelli’s, states in its company FAQ that their two drinks are the same in every way except the label: "Both are 100 percent pure juice from U.S. grown fresh apples. We continue to offer the cider label since some consumers simply prefer the traditional name for apple juice."

The US Apple Association, a nonprofit trade organization that represents growers nationwide, indicates that apple juice can be made from concentrate, which is why you might see water as the first ingredient on the label. Generally, cider is the hard stuff: Crushed apples with minimal processing. Because it can ferment, it's usually found refrigerated. Apple juice can often be found elsewhere in stores, where it can remain stable.

Which you should buy comes down to personal preference. Typically, though, recipes calling for apple cider should use apple cider. Processed juice may be too sweet an ingredient. And you can always try making a pumpkin spice hot apple cider, although we may stop talking to you if you do.
