How SpaceX's sleek spacesuit changes astronaut fashion from the space shuttle era

Nice space helmet as long as you just sitting around.

Space hatches open inward (toward the pressurized area) for a reason. The internal pressure pushes the door onto the bulkhead seals. The pressure helps keep it sealed.

These space helmets are not safe. The internal pressure of the suit is pushing the visor away from the seals. The face shield is held in place by a pivot. There appears to be a circular ring or bladder which expands and seals against the inside of the visor when it is lowered. The visor should be on the inside of the helmet pushing against seals on the inside of the helmet frame. An internal visor design also shields these sealing edges from external impacts.

If the visor pivot or the helmet seal edges are damaged you are going bug eyed in a few minutes.

As long as you are sitting still in a cabin the risk is low, if you are doing anything where something might strike the helmet you do not want this helmet.

A solid fish bowl with a metallic collar is the best kind of helmet since the neck seals are usually metal on metal and quite robust. You can hit the fish bowl with a hammer (don’t go nuts) and it can hold up.

Don't you think that they just might have covered all that during testing? After all, SpaceX is known for testing things till they break.

The times they are a changing.

I can see the advantages of this design, comfort and fatigue are also factors in space helmet design. This helmet design would be a disaster in the gritty environment of the moon.

It is a measured compromise between comfort and safety. It is a passenger helmet and nothing more. It would probably work for several weeks in a hard vacuum. Spacecraft passengers are never supposed to be exposed to vacuum in the first place.

It is the fashionable (rubber dinghy) of space helmets it isn’t meant to replace a working space helmet. Maybe they could paint them yellow and add a rubber ducks bill?
