Rockoon Launch: Japan's AstroX Raises $15M to Send Satellites to Orbit via Balloon-Launched Rockets
Japanese startup AstroX has raised $15 million in Series A funding to develop its revolutionary Rockoon launch system — using high-altitude balloons to carry rockets to the stratosphere before firing them into space. Based in Fukushima's Minamisoma, the company aims to reach space by 2026 and achieve orbital insertion by 2029, challenging the global space launch industry with a low-cost, flexible alternative.
