They'll have to quickly pass the Van Allen radiation belts, which hasn't been done by humans since the Apollo space program in the 1970s.

他们必须快速通过范艾伦辐射带，自 20 世纪 70 年代的阿波罗太空计划以来，人类还从未完成过这样的任务。

A prime example of this is the Van Allen radiation belt, which is a zone of energetic charged particles

一个典型的例子是范艾伦辐射带，它是一个高能带电粒子的区域。

After takeoff, the four-person team is expected to travel into an oval- shaped orbit aboard the Crew Dragon spacecraft, high enough to plunge the vehicle and crew into the Van Allen radiation belts.

预计发射后，四人团队将乘坐龙飞船进入一个椭圆形轨道，轨道高度足以让飞船和宇航员进入范艾伦辐射带。

That will take the four-person crew (which, besides Mr Isaacman, consists of Scott Poteet, his business partner, and Anna Menon and Sarah Gillis, both SpaceX employees) through the Van Allen radiation belts.

这将带领四名机组人员（除了艾萨克曼先生之外，还包括他的商业伙伴斯科特·波蒂特以及同为 SpaceX 员工的安娜·梅农和莎拉·吉利斯）穿越范艾伦辐射带。
