Price, most likely.

价格,最有可能是。

It’s a stretch, however, to call these “spacesuits.”

然而,称这些“太空服”未免太早了。

Here it is:

It looks cool, and that’s fine, but this is not something you can go outside on an EVA in. It’s just backup life support, designed to keep you alive in the event of cabin depressurization, and to give you the minimal mobility needed to fly the craft. It’s a highly simplified design, with not only integral boots but integral gloves. Those are there so they are always on in the event of depressurization—but that’s not a feature you need or want in a proper spacesuit. Since one size definitely does not fit all, that pretty much guarantees this thing is never meant to be pressurized except during testing or a life and death emergency.

看起来很酷,这很好,但你在太空行走时可不能穿这些。它只是后备生命支持而已,旨在在机舱减压的情况下帮助你生存,并为您提供飞行所需的最小移动性。这是高度简化的设计,不仅包括一体式靴子,而且包括一体式手套。因此在降压时它们始终处于打开状态,但这个功能实际上你可能并不需要。单一尺寸绝对不能适合所有人,所以除非在测试或紧急情况中,否则永远不要对这件东西加压。

It’s the functional equivalent of these:

在功能上等同于这些:

Only a lot cheaper, less versatile, and probably safer for non-military passengers. As such, it’s probably a better fit (no pun intended) for what’s meant to be a cheaper, more automated spacecraft. And in fairness, I’m sure they won’t come in only one size.

对于非军事乘客而言,宇航服必须便宜得多,用途更广泛且可能更安全。这样一来,spacex的宇航服对于更便宜,更自动化的航天器来说,可能更适合(无双关语)。公平地说,我敢肯定它们不会只有一种尺寸。

So are they better? For doing work in space, either inside or outside the spacecraft? Absolutely not. But for keeping paying amateurs and passengers safe on a budget? Maybe.

那这些宇航服更好吗?在航天器内部还是外部进行太空工作?绝对不是更好的。但是为了保障那些愿意花钱的的业余人员和乘客的安全呢?也许。
