SSA-01 Module 6 gave the Outer Space Treaty a light preview — what it says, in brief. SSA-04 is a different kind of course: the highest-bias-risk subject in this curriculum, and the one place where stating a rule without also stating who it favors would be a genuine failure of honesty, not just an omission.
Every rule covered in SSA-04, starting now, gets the same four-step treatment — no exceptions, and no module skips the last step.
What the treaty, law, or policy actually says — in plain language, checked against the primary text itself, not a paraphrase of a paraphrase.
Rules aren't written in a vacuum. This step names who was structurally advantaged by the rule as written, and the specific mechanism — not a motive accusation, a description of effect.
Real arguments on more than one side, presented in language their own holders would recognize as a fair summary — not a strawman built to be knocked down.
This course doesn't tell you which position is correct. That's a deliberate choice, not an evasion — space policy is genuinely contested, and a curriculum that picked a side would be teaching opinion as fact.
The Outer Space Treaty opened for signature in 1967 — squarely inside the Cold War Space Race SSA-03 Modules 3–5 covered, six years after Gagarin's flight and two years before Apollo 11. Only the US and USSR had reached orbit at the time it was drafted. That timing matters directly to the "who benefits" question below — the treaty was written by, and largely for, the only two nations that already had the capability it regulates.
The Rule: Article II states that outer space, including the Moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by use or occupation, or by any other means. No country can plant a flag and declare territory.
Who Benefits, and Why: The rule locked in a "no territorial claims" norm before either spacefaring power could act on one. That structurally favored the US and USSR as the only two states with the near-term capability to attempt a claim in 1967 — freezing the field open cost them nothing they could actually use yet, while foreclosing the option for every nation that might develop that capability later. The treaty is also notably silent on resource extraction short of sovereignty claims, a gap SSA-04 Module 4 covers directly.
One Reading
Without this rule, the early space powers could have raced to claim the Moon or other bodies outright, replaying a colonial-era land grab in a new setting. Locking in "no one owns it" before anyone could act was a genuine, rare instance of preemptive restraint.
Another Reading
The two states writing the rule had no pressing need to claim territory yet, and "agreeing" to forgo something neither was ready to use isn't much of a sacrifice — while it locked out every later-arriving nation from an option the drafters never had to actually give up.
Both are live positions in space law scholarship today. This course states them and stops there.
The Rule: Article IV bars placing nuclear weapons or other weapons of mass destruction in orbit or on celestial bodies, and requires the Moon and other celestial bodies be used "exclusively for peaceful purposes" — explicitly banning military bases, fortifications, weapons testing, and maneuvers there. Earth orbit itself gets the narrower WMD ban only, not a full demilitarization requirement.
Who Benefits, and Why: "Peaceful" was never defined in the treaty as "non-military" — in practice it's been read as "non-aggressive." That gap structurally benefits established spacefaring military powers, who can run extensive non-WMD military space activity — reconnaissance, missile warning, the kind SSA-03 Modules 4–5 covered — under a treaty the general public widely assumes bans space militarization outright.
One Reading
Keeping nuclear weapons out of orbit was the actual worst-case scenario the treaty targeted, and it worked — no nation has placed WMDs in space in nearly six decades. That's a measurable, durable success on its own terms.
Another Reading
The "non-aggressive, not non-military" reading let de facto militarization proceed in full view — reconnaissance and missile-warning satellites are as old as the treaty itself — while the treaty's public image as a broad peace agreement stayed mostly intact.
Both are live positions in space law scholarship today. This course states them and stops there.
The Rule: Article VI makes states internationally responsible for national space activities — whether carried out by a government agency or a private company — and requires the relevant state to authorize and continuously supervise any non-government activity under its jurisdiction.
Who Benefits, and Why: Putting the licensing burden at the national level, rather than creating a single international regulator, structurally benefits states that already had mature regulatory infrastructure when commercial spaceflight scaled up — and puts companies based in countries without one at a real disadvantage. This is the direct root of the national licensing-regime differences SSA-04 Module 3 covers through ITAR.
One Reading
Keeping authorization at the state level avoids creating an unaccountable international bureaucracy with power over every nation's private actors, and lets each state calibrate oversight to its own legal traditions and risk tolerance.
Another Reading
A state-by-state patchwork lets companies effectively choose the most permissive regulator to operate under — comparable to maritime flags of convenience — which can undercut uniform safety and liability standards across the industry.

The Outer Space Treaty's actual text (UN Office for Outer Space Affairs), alongside published space law scholarship representing multiple readings of Articles II, IV, and VI. This module set should always be checked for current developments before publishing.
Module 2 covers the later space law instruments — the Rescue Agreement, Liability Convention, Registration Convention, and the Moon Agreement almost no spacefaring nation ratified.
