The year is 1984. Ronald Reagan is President of the United States, the Cold War simmers, and in the realm of space exploration, a dream takes flight – or at least, it's on the drawing board. This is the story of Hermès, the French mini-space shuttle, a project that, while ultimately unrealized in its original form, represents a fascinating chapter in the history of European space ambition and echoes the timeless human yearning for lunar exploration, a yearning captured centuries earlier in Johannes Kepler's seminal work, *Somnium*. The very name "Hermès," invoking the swift messenger of the Greek gods, aptly reflects the ambition of the project: rapid, reusable access to space.
The French space agency, Centre National d'Études Spatiales (CNES), initiated the Hermès program with the goal of developing a small, reusable spaceplane capable of being launched atop the Ariane rocket. This wasn't merely an exercise in national pride; it was a strategic move to establish Europe's independent capability in human spaceflight, a capability largely dominated by the United States and the Soviet Union at the time. By 1984, the initial concept had evolved significantly. The Hermès of 1984, as documented in various sources including JSTOR's archives (112. Bd., H. 4, 4th Qtr., 1984 of Hermes), presented a more refined design, a miniaturized version of the American Space Shuttle, albeit with its own unique characteristics. This iteration, a far cry from the initial investigations, represented years of meticulous engineering, design compromises, and technological hurdles overcome. It was a tangible step towards realizing a European dream of independent human spaceflight.
The 1984 design, as depicted in CNES “HERMES” [1984] documentation, reveals a spacecraft far more sophisticated than its initial conceptualization. It was envisioned as a reusable vehicle, capable of carrying a crew of up to four astronauts and a significant payload into low Earth orbit. This capacity for reusability was crucial, as it promised to drastically reduce the cost per mission compared to the expendable rockets of the time. The ambitious goal of reusable technology echoes the enduring human desire for efficient and sustainable space exploration, a desire that transcends eras and is reflected in the enduring appeal of Kepler’s *Somnium*, a work that envisioned lunar travel centuries before its technological feasibility.
