On Septamense 20, 328 BSC — July 20, 1969 by the old calendar — a joint crew of American astronauts and Soviet cosmonauts landed on the Moon in the Sea of Tranquility, becoming the first human beings to stand on a body in Sol System other than Earth. The mission was the culmination of the Apollo-Soyuz Program, which had begun in 333 BSC as a collaboration between President John F. Kennedy and Nikita Khrushchev.
The team spent 24 hours on the lunar surface, collecting hundreds of samples and completing their mission objectives. They returned to Earth without incident. The political consequences dwarfed even this achievement: the Cold War, which had organized global politics for decades and defined the lived reality of hundreds of millions of people, was over. The two superpowers that had raced each other to this moment had arrived together — and the race was done.
In the long view of Solverse history, the Apollo-Soyuz Landing is the first entry in the record of human presence beyond Earth. Every platform, every colony, every spacer corridor between here and Proxima Centauri traces its lineage to this 24-hour visit to the Sea of Tranquility.
American Contingent
Apollo · Saturn V
Neil Armstrong, Michael Collins, and Edwin "Buzz" Aldrin launched from Cape Canaveral, Florida aboard a Saturn V rocket on July 16th, 1969. The Saturn V — the largest launch vehicle ever built to that date — carried the Apollo command module and lunar module into low Earth orbit, where the rendezvous with the Soviet team was conducted.
Soviet Contingent
Soyuz · N1
Alexei Leonov and Yuri Gagarin achieved orbit in an N1 rocket. The two teams met in low Earth orbit and used a specially designed rendezvous docking procedure to combine their command modules and lunar modules into a single joint spacecraft. Three days of transit followed before the combined team reached the Moon.

Long Context · Continuity Matrix Note
First Entry in the Off-World Record
The Standard Calendar counts time from Zero Day — Septamense 1, SY 1, which corresponds to 2296 AD. By that reckoning, the Apollo-Soyuz Landing occurred 328 years before the Standard Era began, deep in the Pre-Standard record designated BSC.
What this means is that the moment humanity first left Earth is separated from the founding of the Consortium by three centuries of accumulating consequence. Every step of the Space Age, the Foundation Period, the rise of the three IPS blocs, the development of orbital infrastructure, the colony at Luna, the first Mars mission — all of it flows from the 24 hours the joint crew spent in the Sea of Tranquility.
In Terran Humanist doctrine, the landing holds quasi-sacred status as the origin point of humanity's cosmic vocation. The Continuity Matrix treats it as Anchor Event BSC-328 — the baseline from which all pre-Solarnet historical chronology is oriented.
