Japanese aerospace startup AstroX is set to pioneer rocket launches from stratospheric balloons, operating at altitudes ranging from 20 to 25 kilometers, with a target to reach space at an altitude of 100 kilometers as early as December this year. The rocket, measuring approximately 5 meters in length, will be powered by synthetic resin solid fuel and equipped with sensors designed for low-frequency sound observation. Prior to December, AstroX intends to carry out tests involving balloon releases and stratospheric ignitions. The company aims to deploy small satellites into orbit by 2029 and achieve full commercialization post-2030. It anticipates conducting 50 launches annually, with each launch estimated to cost around 500 million yen.
