Abstract

fetched live from OpenAlex

The Japan Aerospace Exploration Agency (JAXA) is among the six largest national space agencies in the world, along with China's CNSA, US's NASA, and Russia's Roscosmos. JAXA's budget is more than $1 billion USD—bigger than France or Germany individually, and more than that of Italy, India, Canada, and the UK combined. And yet, Japan's significant contributions have largely been absent in the history of space exploration, and space exploration largely absent in the history of technology in Japan. The Islands and the Stars corrects this conspicuous oversight. Through meticulous archival research in Japanese and anglophone archives, Subodhana Wijeyeratne examines the history of Japan's space exploration efforts over nearly a century. Wijeyeratne traces the evolution of Japan's space program from its early origins in the 1920s, through the postwar period of rapid technological innovation, to the consolidation of its various institutional elements into JAXA in 2003. He situates Japan's space programs within the broader history of the country's postwar recovery, economic growth, and cultural identity, while also considering their place within global trends in space exploration. Through this narrative, Wijeyeratne not only illuminates Japan's centrality to the global history of science and technology, but also offers insights into the future of global space exploration, emphasizing the importance of diverse voices and perspectives in the quest to understand our place in the cosmos.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
