On the left shoulder of the EVA suits used by 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?

It's the patch worn by all spacewalking astronauts (and maybe cosmonauts, too, when they're wearing an American EVA suit... not sure on this).

I'm also not sure what its official name is. It's a version of the famous "man as machine" drawing that I want to say DaVinci made?

I'm sure the more informed others here can fill in the details, but that's the basic significance of the patch.

I believe that 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, vs. 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.

NASA astronauts all have a blue and gold patch on the right shoulder of their Extravehicular Mobility Units (EMU), or space suits, when they venture outside the space shuttle on Extravehicular Activities (EVAs), or space walks. 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.

This week I picked up an Extravehicular Activity (EVA) patch. This is the one with the yellow border worn by spacewalking astronauts on the shoulder of their spacesuit. The patch is an adaptation of Leonardo da Vinci's sketch from Proportional Study of Man in the Manner of Vitruvius, which also served as the inspiration for the Skylab Expedition 2 mission patch.

The question: The number of stars on this patch has gone from 3 to 5.

Doe anyone know the meaning behind this?

Perhaps the two new stars represent two milestone STS EVAs.

I've noticed in pictures from the EVAs that the "new" five star version of the patch is being used. Is this the first mission that the five stars have emblazoned the EVA/EMU suits?

This is this 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.

I acquired this patch which matches the Extravehicular Activity (EVA) patch first introduced during the STS-6 mission. It's not quite the same as an authentic one I found sold at auction.

Mine has red fill in the chest area below the blue triangle, and the hands don't quite touch the red border. Is this a late reproduction or one sold at time of mission?

On edit: Just found this same patch on an eBay store (mealticket2) - no need to answer, as I should have looked harder!

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? Thank you.

In the case of the 'Vitruvian Man' EVA insignia created by Hamilton Sundstrand for use on the Shuttle EVA suits, I was wondering if there was a cloth patch that can be regarded as vintage to the emblems 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 3 stars, which can be considered as 'collectable' with particular identifiers, such as cloth back or stitching patterns?

Yes, as posted above by prontouk, the 3-star version is/was available. The one I have is the 3-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 5-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.

Question then.... If the five stars represent the ISS spacewalk, did this then become the official EVA insignia... when?

That spacewalk was on STS-104, so did they start wearing the five star right after it did it take a bit longer in time to be used?

I have not found an answer yet searching the net myself... Thank you.

I developed the EVA patch and it was selected by NASA. Still have the original artwork, the three stars were for my three brothers.

It was designed from Leonardo da Vinci's dimensions of man. Now in a spacesuit.

It was developed while I was on Hamilton Standard's EVA team. GSE group. I know this firsthand.

The reference to Fred Keune was correct, he was the manager of Hamilton Standard, and the medical director provided concepts for the patch.

I didn't relate the three stars to previous milestone events. I thought my three brothers were a better example. However NASA chose the right sign for many missions. Five stars sounds good too.

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".

Curious... Anyone know when AB was using these round stickers under the backing vs. the square ones now used? This would help to date this patch. I'll check later, but I don't think mine has this sticker on the back, making it an earlier version. Maybe I'm wrong?

I believe the order is round AB Emblem branding sticker, no sticker, white sticker (the latter, as noted elsewhere, the result of a change in U.S. law).

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 checked and the one I have is sealed without a sticker. Purchased it from Spaceland Enterprises, September, 1991 (not November, '91 as I noted earlier). So yeah, it could be "newer" than the ones with the round sticker. I'd still call it vintage considering the date, but certainly not an "original".

I like the mission ops EVA patch pictured above too.

It was also 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. My question here is maybe it's a difference between the 3 and 5 star versions? Either way, which one is "official"?

I'm not sure a patch dating to 1991 can be considered vintage if the original design was introduced in 1983.

Unless there were no embroidered examples produced during its first decade...

Agreed Robert. It's an older one, but certainly not vintage. Especially considering that the round stickers came first! Thanks for the correction.

I'm afraid I can't upload images at present but I've found this from Goldberg Auctions, which had one as a flown presentation (lot 1439), just the front shown though. The original three-star version never had the black outlines.

Thanks, Panther for the image.

Another difference not well stated here is that on the original 3-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 3-star versions WITH the black outline have this red filled area and the gloves do NOT touch the red box.

The 5-star version appear to all have the black outline and the gloves do touch the sides of the red box.

I know the left shoulder always has a flag, of whatever country the astronaut is from. But, do they change the flag on the backpack too? Or is it always a US flag?

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?

Just received a Hamilton Standard version, as designed by michaelangelo (see previous posts). It is the same as Go4Launch mentioned, the top one Robert posted on 1/17.

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?

Picked it up on eBay. Have been waiting for about 3-4 months for one to be listed. And it's the only one I've seen offered since I started looking. So I don't know if the seller would have any more to sell.

Email me if you want to try contacting them.

Thanks again. I've been seeing the reproductions from a known seller, but would like the "real" thing or close to it. I know a seller was selling it for $70 a while ago, is this the same one?

Possibly. And yes, it is the "real" thing. I inadvertently missed the deadline to bid the first time and it closed without selling. It was then relisted for $65. They were also accepting offers. So I made an offer very shortly after it was relisted. Possibly even the same day. He countered ($55) with some additions (a couple Gemini covers and a couple other similar items) which I accepted. Not a bad deal from the sound of things now.

(Previous post corrected. I was thinking of another patch I just won that I had to outbid to get. Sorry for any confusion.)
