NASA needs good weather to launch Ares I-X because engineers need to see the rocket flight all the way through first stageseparation, which will mark the end of the test.
Therefore, based on the laboratory test, an industrial test on the stage grinding and stage separation process was carried out.
为此，在实验室试验的基础上进行了阶段磨选工业试验。
