@planet4589 @NASASpaceflight Cryogenic fuel is an added challenge, as it evaporates to create fuel-air explosion risk in a partially oxygen atmosphere like Earth.
That said, we have a lot of sensors to detect this. More later.
@NASASpaceflight的4589号飞机的低温燃料是一个额外的挑战，因为它在像地球这样的部分含氧大气中蒸发，从而产生燃料空气爆炸的风险。
也就是说，我们有很多传感器来检测这一点。稍后再介绍。
