One of the more innovative uses of Velcro included putting a patch into EVA suits to assist in scratching the astronaut's nose.

Considering that Velcro has two different textures (hook and loop) which adhere together, which side was used for the nose-scratching patch?

Update: Russian spacesuits have a different solution to the problem: a spongy piece of foam in the helmet. It also allows the cosmonaut to hold the nose shut while blowing, allowing a hands-free Valsalva maneuver which is useful for equalizing pressure in the ears.

  • $\begingroup$ US suits also have the Valsalva device. space.stackexchange.com/q/41296/6944 Note the pic in the question has both the Valsalva device and the feedport where the Velcro was attached. $\endgroup$ – Organic Marble Mar 20 '20 at 13:51

This close-up photo of Neil Armstrong's feedport from a NASA webpage appears to be hook.

OrganicMarble was therefore correct that it varies between astronauts, as a personal preference item.

Armstrong's feedport

  • $\begingroup$ Much, much better picture. +1 Odd that it covers the hole in the feed port. $\endgroup$ – Organic Marble Apr 3 '20 at 3:33
