There is an article in Russian "Why do the American space suits look so different from Russian ones?" which claims that the new SpaceX suits are designed for looks, and have several issues, which, one can conclude from the article, would make them inferior to existing (especially Russian) ones.
Listed are at least (Google translate with some fixes by me):
This spacesuit has no joints(hinges/articulations? шарнир in Russian) at all, except on the fingers of the gloves - under pressure the astronaut will not be able to move at all. It remains only to wait for an emergency landing. So automation is expected to do everything on landing operations. Let me remind you - other spacesuits have many joints for mobility, which means more comfort and opportunities for astronauts. Will the SpaceX suit fulfill its survival function when depressurizing the capsule? Yes, it will. But it will do poorly. Compared to others, it will be very inconvenient.
Further down the list is the unusual entry. The astronaut will have to get into spacesuit like a worm, and someone should help him. And then you still need to get out somehow! Convenient? No. Can I use it? Yes. But why is it so complicated? That is, not how to make it more comfortable (read - more functional), but better looking so that zipper is not visible. How is the entrance to the Sokol (Russian emergency rescue suit) made? It is in front, on the chest, and the astronaut dresses himself, fastens himself, and then he undresses himself without help.
SpaceX suit has individual sizes. Current trends in spacesuit construction are to make spacesuits suitable for people of different stature and complexion. For commercial space, it is important to make a spacesuit with universal measurements in order to have as small a size as possible, but with the possibility of adjustment. This will reduce the cost of production and operation, will allow you to quickly make a replacement and in a couple of minutes adjust the suit to the figure of a new astronaut. Here, everything was done as at the dawn of manned space exploration, when there were no mass flights, but there were small cosmonaut detachments - and state programs did not count money at all.
A few words about the helmet. Cool looking. And uncomfortable. The printed plastic is not particularly durable, so the helmet wall thickness is about 25 mm. For other spacesuits, it is made of aluminum, with a wall thickness of 1.5 mm. The helmet was made like a motorcycle helmet, designed for driving at high speed, when ventilation is well organized according to speed, to remove exhaled gas and cool the head. There is no speed or free air flow in space, which means that there may be problems with ventilation and cooling.
The dimensions of the helmet of the [Russian] Sokol spacesuit are larger and more comfortable. NASA has also increased the size of helmets for their shipboard spacesuits - now you can even freely rotate your head inside them. In the SpaceX suit, the smaller helmet size allows you to turn and tilt your head only at a small angle.
But there is another, more important circumstance - the development, testing, development and certification system at SpaceX. Usually, when the tester, and then the astronaut, says: “I’m uncomfortable or bad here, I need to improve it,” the design is changed and finalized so that there are no complaints. For example, an astronaut raises his hand in his shoulder to make it more comfortable to climb and climb into the hatch of the ship, and says: “And here a rigid shoulder pad prevents me from raising my hand.” In a regular company, they take it and rip it off - that's all. And nothing more prevents the astronaut from raising his hand: it has become more convenient. And here it is forbidden to do so. After all, these hard shoulder pads introduced by a fashion designer, they can not be touched! They do not carry functionality, they are for beauty. Constructor cannot make changes, astronaut or tester cannot complain
Considering the naked propaganda we frequently encounter coming from Russia, my question is:
