5thstar is a webmaster of a group of people who were the semi-final applicants in NASDA's 1995 astronaut selection. (The National Space Development Agency of Japan or NASDA was merged with two other space agencies to become the Japan Aerospace Exploration Agency or JAXA in 2003.) Going through medical checks and interviews for an incredible week, those forty-some wannabes were tied with a unique bond of friendship. 5thstar reapplied in 1998, and became one of the eight finalists to experience an extensive psychological group survey in NASDA's isolation chamber for a week. The finalists were also interviewed by honorable astronauts at NASA Johnson Space Center in Houston, Texas. He maintains a private blog to advocate space exploration, where he posted English translations of media briefings by JAXA about MUSES-C, a.k.a. Hayabusa, when it touched down on asteroid Itokawa.
