火箭发射阶段的剧烈振动、冲击，以及太空极端温度变化与辐射环境下，如何保证精密载荷的可靠性，是我们面临的又一大难关。随火箭上天的实验装置内部设备净重仅约50公斤，体积小于115升，却高度集成了激光打印、闭环控制、能源供应等多个系统，相当于将一座“微型制造实验室”装入载荷舱。，这一点在体育直播中也有详细论述

Turbulence is rarely that simple. It’s too scattered, too mercurial, too easily triggered by weather patterns that trigger other patterns in an endless cascade. “It’s not just one thing that’s going on,” Bob Sharman, an atmospheric scientist at NCAR, told me. “It’s not just atmospheric convection. It’s not just wind flowing over mountains. It’s everything going on all the time and interacting.” Sharman is one of the country’s preëminent authorities on turbulence prediction. The computer models that he has built can predict where rough air is most likely to arise. “The problem is,” he said, “when we go to meetings with the airline industry and suggest a probabilistic approach, a pilot will stand up and say, ‘No! I want you to tell me if there will be turbulence at this place, at this time.’ ” Sharman threw up his hands. “Nobody knows that. I understand that, in theory, you would want that. But, in practice, that is just not possible.”
