infernal weightless───地狱般的失重
The astronauts are conducting a series of experiments to learn more about how the body adapts to weightlessness.───那些宇航员正在进行一系列实验，以便更多地了解人体如何适应失重状态。
More importantly, scientists are already queuing for seats on these low-gravity space-flight services so they can collect data during a few minutes of weightlessness.───更重要的是，科学家们已经在排队争取这些低重力太空飞行服务的座位了，这样他们就可以在几分钟的失重状态下收集数据。
Uniformly, these people experienced weightlessness and the sensation that their bodies were being stretched lengthwise.───无一例外地，这些人都体验到了失重和身体被纵向拉伸的感觉。
I had a genuine sense of weightlessness, as if the car had taken flight.───我有一种真正的失重感，好像车在飞翔。
