Instead, it is released during reentry and burns up in the atmosphere.

相反，它在再入过程中被释放并在气层中燃烧。

The vehicle will aim to guide the ISS through a final reentry into Earth's atmosphere.

该飞行器的目标是引导国际空间站最后一次重返气层。

In other cases, the extra pathway can set up a reentry circuit.

还有一种情况，额外通路可建立一个折返通路。

They can be caused by abnormal automaticity, reentry, or a triggered afterdepolarization.

可以由异常自律性、折返激动或被激发的后除极引。

But the final part of the operation is reentry.

但这次行动的最后一部分是重返气层。

And we screwed up on reentry.

Then it will be all programmed to come back to Earth where it will burn up on reentry.

然后这个垃圾将被程序带回到，在重新进入气层时被烧毁。

NPR's Ted Robbins says most of the charges were illegal entry or illegal reentry into the U.S..

NPR新闻的泰德·罗宾表示，部分指控内容为非法进入美国或非法回美国。

For reentry, Carpenter has to manually turn the capsule 180 degrees so the heat shield faces down.

为了顺利返航，Carpenter 不得不手动将返回舱升到 180 度以打开高温防护层。

The friction of reentry should be enough to destroy the debris, though this method doesn't always work perfectly.

再入过程中的摩擦应该足以摧毁这些垃圾，尽管这种方法并不总是完全有效。

The plan involves developing a new spacecraft to safely guide the ISS during its final reentry through Earth's atmosphere.

该计划包括开发一种新的航天器，安全引导国际空间站最后一次重返气层。

And even the astronauts aboard Apollo 11 during reentry with Earth's atmosphere only experienced a force of 7.19 Gs.

甚至阿波罗 11 号上的宇航员在返回气层时也只受到了 7.19G 的力。

NASA later identified it as detritus from the International Space Station that was expected to burn up during reentry.

NASA 后来确认这是国际空间站的碎片，原本预计在再入过程中燃烧殆尽。

If indeed the heat shield was loose, during reentry, the spacecraft would probably get very hot...temperatures of 3,000 degrees.

如果高温防护板确实没有固定好，那么返回气层时飞船的温度可能升得很高...... 可以高达 3000 度。

During reentry, ionized plasma builds up around the spacecraft, causing a radio blackout for about three minutes.

返回途中飞船周围的等离子体引无线电联络中断了三分钟。

NASA still fears the high g-forces or extreme temperatures of reentry could kill him.

NASA 仍然担心这种超强重力或重返时的极端气候差异让他送命。
