Twice a year, the residents of Kakuda -- a small city of rice paddies and persimmon orchards in southern Miyagi Prefecture -- open their calendars to something extraordinary. JAXA's Kakuda Space Center throws open its gates, and locals stroll past liquid hydrogen test stands and cryogenic fuel systems as casually as visiting a neighborhood festival. It is a peculiarly Japanese juxtaposition: the rural and the cosmic, separated by nothing more than a chain-link fence. Behind that fence, engineers have been perfecting the fire that lifts satellites, space probes, and astronauts into orbit since 1965.

The story begins in 1965, when Japan's National Aerospace Laboratory established the Kakuda Branch Laboratory on a stretch of land far enough from population centers to muffle the roar of rocket engine tests. The location was deliberate -- nestled in the Tohoku countryside, the s...

The LE-5 engine, a liquid hydrogen and liquid oxygen upper-stage powerplant, was developed here and became the heart of Japan's H-I rocket program. Its successors, the LE-5A and LE-5B, powered the second stages of the H-II and ...

A liquid hydrogen rocket engine test facility where fuel burns at temperatures exceeding 3,000 degrees Celsius. A high-pressure liquid oxygen turbo pump test stand that subjects components to forces that would shred ordin...

Kakuda Space Center: The Quiet Side of the Space Race

Photo credit NASA, Public domain. Unlike the spectacle of a launch pad, a rocket engine test center operates in relative anonymity. There are no countdown clocks broadcast on television, no crowds gathered on beaches to watch. The work is iterative, painstaking, and largely invisible -- a single engine component ...
