About S-Booster

It was held for the first time in 2017. 2023 is the sixth contest.

S-Booster is hosted by the Cabinet Office of Japan, and is run by the Executive Committee composed of the Japan Aerospace Exploration Agency (JAXA) and the New Energy and Industrial Technology Development Organization (NEDO).

The "S" in S-Booster stands for four things: it is part of S-NET's activities (*), and signifies the Startup of Space-based ideas and their future Success. In addition, "Booster" expresses our hope that this contest will function as a propulsion device to help "launch" ideas into orbit (markets).

* Space New Economy Creation Network (S-NET) activities were started by the Space Development Strategy Promotion Secretariat, Cabinet Office of Japan on March 22, 2016 to bring together companies, individuals, organizations, and others interested in creating new industries and services on the keyword of "space."
