On the left shoulder of the EVA suits used by space shuttle astronauts, there's a patch of an astronaut in motion in a circle.

What is the name of this patch and why is it what does it symbolize?

The EVA astronaut patch is a take-off on Leonardo da Vinci's Vitruvian Man.
This diagram and text are taken from an illustration of Vitruvius' theory by Leonardo da Vinci.

Vitruvius, the architect, says in his work on architecture that the measurements of the human body are as follows that is that 4 fingers make 1 palm, and 4 palms make 1 foot, 6 palms make 1 cubit; 4 cubits make a man's height. And 4 cubits make one pace and 24 palms make a man.

The length of a man's outspread arms is equal to his height.

From the roots of his hair to the bottom of his chin is the tenth of a man's height; from the bottom of the chin to the top of the head is one eighth of his height; from the top of the breast to the roots of the hair will be the seventh part of the whole man. From the nipples to the top of the head will be the fourth part of man. The greatest width of the shoulders contains in itself the fourth part of man. From the elbow to the tip of the hand will be the fifth part of a man; and from the elbow to the angle of the armpit will be the eighth part of man. The whole hand will be the tenth part of the man. The distance from the bottom of the chin to the nose and from the roots of the hair to the eyebrows is, in each case the same, and like the ear, a third of the face.

From Space Mission Patches:
Hamilton Sundstrand, the manufacturer of the Shuttle EVA (extravehicular activity, known colloquially as a "space walk") suits, designed this patch to be affixed to all of its space suits — since company logos are verboten on NASA equipment. This patch is also based on the da Vinci "Vitruvian Man" theme, but is updated for the space age: the central human figure is an astronaut suited for EVA. While this is a bit of a liberty with a classic image, it does address two modern concerns: the spacesuited figure is androgynous to reflect that female astronauts perform EVAs as well as male astronauts; and it presumably cushions delicate sensibilities from abuse.
The patch is known simply as the "EVA" insignia.

This may be "old" news, but the EVA patch has been updated. The new version now has five stars, versus the old three. The stars represent each U.S. program that had a spacewalk, so the two new ones are of course space shuttle and ISS.

I volunteer at the National Air and Space Museum and talk about living and working in space. Several weeks ago a gentleman stopped by who worked for the spacewalk team, and had given me the new version, in his words the patch was very new.

From a NASA Exploration, Integration and Science Directorate newsletter:
NASA astronauts all have a blue and gold patch on the right shoulder of their Extravehicular Mobility Units (EMU), or spacesuits, when they venture outside the space shuttle on extravehicular activities (EVAs), or spacewalks.

The theme of the patch is "Extending the Dimensions of Man." It is derived from the Leonardo da Vinci sketch entitled "The Dimensions of Man" and is meant to be an extension of the dimensional, medical and scientific aspects of the original work.

It is fitting that the theme of the patch is associated with the original da Vinci work since the evolution of the space shuttle EMU from its Gemini, Apollo and Skylab origins represents the closest achievement of the ultimate EMU design goal — that of providing EVA mobility limited not by hardware but by man's natural range.

The three stars on the patch represent three historic milestones in extravehicular activity: America's first EVA by Ed White on Gemini IV; man's first steps on the lunar surface, made possible by the Apollo space suit worn by Neil Armstrong and the space walks of Pete Conrad and Joe Kerwin to repair, and eventually save, Skylab.

The Space Shuttle EVA patch was conceived and designed by Fred Keune, manager of Hamilton Standard's Houston office at the start of the space shuttle program, and Walter J. Wick, M.D., Hamilton Standard's medical director.

The Shuttle EMU suits first flew on STS-5, but on that flight there were some problems with the suits, so the spacewalk was cancelled. On the next flight, STS-6 the first EVA from the Space Shuttle took place, and on that flight the EVA patch first "flew" in space.

The number of stars on this patch has gone from three to five. Doe anyone know the meaning behind this?

Perhaps the two new stars represent two milestone space shuttle EVAs.

I've noticed in pictures from the STS-114 EVAs that the five star version of the patch is being used. Is this the first mission that it has emblazoned the EMU suits?

STS-114 is the first flight (and first US EVA) since the patch was updated. From the EVA Program Office website...
The five stars on the patch represent five historic milestones in U. S. extravehicular activity: America's first EVA by Ed White on Gemini IV; man's first steps on the lunar surface, made possible by the Apollo space suit worn by Neil Armstrong; the space walks of Pete Conrad and Joe Kerwin to repair and eventually save Skylab; the first space shuttle EVA performed on STS-6 by Story Musgrave and Don Peterson; and the first International Space Station (ISS) EVA performed by Mike Gernhardt and Jim Reilly.

Ignoring the black or white backgrounds on these photos, does anyone know what is the correct color for the outside of this patch? Is it the lighter or darker yellow?

Is there a cloth version of this patch that can be regarded as vintage to the emblem's creation and first use?

I know that it was first utilised during STS-5 (cancelled EVA), then during an actual EVA on STS-6, but is there such a patch (non-beta cloth), with the original three stars, which can be considered as "collectable" with particular identifiers, such as cloth back or stitching patterns?

The three-star version is/was available. The one I have is the three-star version that I acquired in November 1991, so I'd say it was vintage, or pretty darn close at least. I am looking at it now after seeing this thread. I suppose I now need to find a five-star version!

It has the darker yellow border like the one on the left. The one on the right looks to be a sticker, which could have had a lighter yellow used in printing.

The correct outer color is the darker yellow, with no black outline around the stars or the red square.

I have a vintage AB Emblem example, glue back with a white circular sticker under the glue which reads "Made in USA A-B Emblem Caps Weaverville."

From astronaut Doug Wheelock (@Astro_Wheels) on Twitter:
'Vitruvian Spaceman' patch on our EMU suits, worn from the water. A symbol of the art and science of the 'spacewalk'.

From NASA extravehicular activities flight controller and instructor Scott Wray (@stingwray) in response to Wheelock:

We also use the 'Vitruvian Spaceman' for the EVA Training/Flight Control group patch...

I like the mission ops EVA patch pictured above.

It was mentioned that the official patch does not have a black outline around the stars or the red border square. Yet the one pictured above, obviously in actual use, does have black borders. Maybe it's a difference between the three and five star versions? Either way, which one is "official"?

The original three-star version never had the black outlines.

Another difference not well stated here is that on the original three-star version, the lower set of outstretched gloves touch the sides of the red box and is missing the red fill under the blue triangle on the right side of the chest.

The three star versions with the black outline have this red filled area and the gloves do not touch the red box.

The five star version appear to all have the black outline and the gloves do touch the sides of the red box.

I've always wanted to get an "authentic" or authorized reproduction one of these, but I've seen many versions/variations to the patch such as the style and placement of the stars. I know that the symbology is mentioned in this thread, but is there something significant or different to them?

The top patch posted by Robert above on 1/17 is identical to one I received from Hamilton Standard in 1983.

Just received a Hamilton Standard version. I can say that it is better than the pictures show. The quality is much better than the other versions and it looks much better in your hand. I am glad to have the history behind this patch.

Curious, does anyone know how many of this version were produced?

And unless my eyes are playing tricks on me, the new embroidered one is now being used on the EMUs on the ISS.

When did the patch go from three stars to five stars?

It seems to me the patch worn on recent EVAs is not identical to AB's product.

Apart from the obvious difference that it is embroidered on a square of white twill, the stitching seems finer and the top of the gold visor appears to be more rounded. Other details match pretty well; is AB the manufacturer of this particular version?
And if so; could we convince them to make it available to collectors?
