Three People, One Idea, No Contact
SSA-02 Module 1 already covered the rocket equation itself. This module covers the person who wrote it down, the two others who reached similar conclusions without knowing he existed, the volunteers who kept the idea alive with no government funding — and how that theoretical work became a weapon before it became a way to reach orbit.
Three Founding Theorists
None of the three had meaningfully read the others' work when they published their own — the same core ideas emerged three separate times.
Konstantin Tsiolkovsky
Russia, 1857–1935
A largely self-taught, deaf schoolteacher who published the rocket equation (SSA-02 Module 1) in 1903 and described multi-staging, space stations, and airlocks conceptually — decades before any were buildable. Lived in relative obscurity; the Soviet state canonized him as a founding figure only after his death.
Robert Goddard
USA, 1882–1945
Launched the first liquid-fueled rocket in 1926. A 1920 New York Times editorial publicly mocked his published claim that a rocket could work in the vacuum of space — the paper issued a correction, but not until 1969, the week of Apollo 11. Worked with minimal institutional support for most of his career.
Hermann Oberth
Germany/Transylvania, 1894–1989
Published "Die Rakete zu den Planetenräumen" (1923), independently reaching conclusions close to Tsiolkovsky's. Became a mentor figure to Germany's amateur rocketry scene — including a teenage Wernher von Braun, who would go on to lead the program covered later in this module.
The Voluntary Societies
Between the theory and the first state rocket programs, rocketry survived almost entirely as an amateur, self-organized pursuit.
VfR — Verein für Raumschiffahrt (Germany, founded 1927)
The "Spaceflight Society" — Oberth was a founding member, and its amateur test launches at a Berlin site nicknamed the "Rocket Airfield" gave a teenage von Braun his practical start, years before any military involvement.
American Rocket Society (founded 1930 as the American Interplanetary Society)
Started by science-fiction writers and enthusiasts in New York, it shifted toward serious engineering experimentation within a few years — an early sign that the amateur and scientific communities weren't as separate as they looked.
British Interplanetary Society (founded 1933)
Produced a detailed conceptual lunar mission design study in the 1930s — decades before Apollo — entirely as a volunteer exercise, with no realistic near-term hope of building any of it.
The V-2
This is where the story stops being purely inspirational. The V-2 is the direct technological ancestor of postwar rocketry, and it was built as an instrument of war — the two facts don't cancel each other out.
The German Army recruited VfR members, including von Braun, into a state rocketry program based at Peenemünde. The result, the V-2, was the first human-made object to reach the edge of space on a suborbital trajectory — and was fired at London, Antwerp, and other Allied cities starting in 1944, killing thousands of civilians.
Production is a documented atrocity in its own right: V-2s were mass-built at the Mittelwerk factory using forced labor from concentration camp prisoners under the Mittelbau-Dora system, in conditions that killed more people than the weapon did in combat. Any honest account of rocketry's origins has to include this — it's not a footnote to the engineering story, it's part of it.
Where the V-2 Went Next
As the war ended, both the US and the USSR raced to capture V-2 hardware, documentation, and engineers — and built their early rocketry programs directly on what they took.
US Lineage
Operation Paperclip
Von Braun and much of his Peenemünde team surrendered to US forces and were brought to America under Operation Paperclip, along with captured V-2 hardware. That team became the technical core of the US Army's rocketry program, and eventually of NASA itself — a direct line running to the Saturn V.
- Von Braun's team relocated intact
- Became foundational to NASA's launch vehicles
- A history the program didn't advertise for decades
Soviet Lineage
Trophy Technology
The USSR captured other V-2 engineers, remaining hardware, and production documentation from the parts of Germany it occupied. Soviet engineers — Sergei Korolev prominent among them — reverse-engineered and then rapidly exceeded V-2 technology, laying the groundwork for Sputnik a little over a decade later.
- Built on captured hardware and expertise
- Korolev's program soon surpassed the original design
- Led directly into Module 3's Space Race
Key Terms
- Rocket Equation
- Tsiolkovsky's 1903 equation linking exhaust velocity and mass ratio to achievable velocity change — covered in depth in SSA-02 Module 1.
- VfR (Verein für Raumschiffahrt)
- Germany's amateur "Spaceflight Society," founded 1927 — Oberth was a founding member, and it gave von Braun his practical start.
- Peenemünde
- The German Army research facility where the V-2 was developed under a state-funded military program.
- V-2
- The first human-made object to reach the edge of space on a suborbital trajectory, and the first long-range ballistic missile used in combat — the direct technological ancestor of postwar rocketry.
- Mittelwerk / Mittelbau-Dora
- The underground factory and associated concentration camp system where V-2s were mass-produced using forced labor, under conditions that killed more people than the weapon did in combat.
- Operation Paperclip
- The US program that brought Wernher von Braun's team and captured V-2 technology to America after World War II, forming the technical core of early US Army and later NASA rocketry.
