A novel method for micro-gravity experiments using high altitude balloon is now under development in JAXA. The notable feature of this system is its double-shell structure. Dropped from the high altitude balloon, the inner shell falls freely for 30 to 60 seconds because the outer shell is controlled not to collide with the inner shell. Sixteen number of cold gas thrusters are installed on the vehicle to control not only its falling attitude but also spacing between the inner shell and the outer shell. This paper presents design strategy and verification test results of the 50 N cold gas thrusters developed for this micro gravity experimental system. The preliminary results of the flight test are also presented to show its feasibility.
