This paper describes the outline of our space experiment plan for validating the new atomization concept derived from our past drop tower experiments. The planned experiment is the microgravity version of conventional laboratory experiments observing the breakup behaviors of water jets slowly issuing from a various nozzle into the atmosphere. The scientific significance of this experiment is explained by pointing out the serious theoretical difficulties in the existing atomization theories and then describing how these difficulties are resolved by the new concept which reveals the origin of unstable waves responsible for liquid breakup in various situations and make the breakup phenomenon quantitatively predictable, which can never be achieved by far.
