The spacesuits used by the Gemini 7 crew were drastically different from previously worn Gemini suits.

Besides the EVA suits that had "extra layers" for protection, were all other suits worn (from GT-3 through GT-12) basically the same, or were modifications made as the program progressed?

Also, was the Apollo 1 suit similar to the ones worn for Gemini?

The Gemini suit for EVA was a "work in progress". Ed White's spacesuit was not the same of the Buzz Aldrin's suit.

The intravehicular Gemini suit was basically the same from GT-3 until GT-12.

Apollo block 1 spacesuit was a intravehicular Gemini with small alterations (cover layer, shell on the helmet, pockets on the legs, flag on right shoulder).

My cousin was a suit tech for David Clark Co. for the entire Gemini program and Apollo 1 crew.

He could answer all these suit questions with great detail, but he unfortunately passed away unexpectedly a year ago.

Every time I see a suit thread like this, I think of all the stories he had to tell of all the astronauts involved. What a loss.

A description of the Gemini 4 EVA suit and the modifications made to the EVA suits for Gemini 8 thru 12 can be found in Section 4.1 of this NASA SP-149 Summary of Gemini Extravehicular Activity document.

NASA photo S67-297 shows the upper portion of the Gemini 4 extravehicular coverlayer.

The extravehicular coverlayer was made in two parts - a main part which covered the torso and a removable jacket (fig. 4.1-4) which covered the arms and shoulders. The use of the removable jacket permitted the pilot to free himself of the added encumbrance of the coverlayer in the area of the arms and shoulders after the EVA was completed.

I would say yes. Compare the two Gemini 4 suits in this launch day photo. It looks like Ed White is wearing the extravehicular coverlayer.

That's a large American flag on McDivitt's shoulder. Anyone know the dimensions?

I believe this was the first use of flags on suits. The Technicolor logo shirt in the foreground is also interesting.

..."The name we selected for the vehicle was American Eagle. Unfortunately, we were unable to use this, and we were known as Gemini IV.

Ed and I used the American flag on our shoulders as our patch. This was the first time the American flag had been worn on a pressure suit and it has continued to be used there ever since. The original flags we had sewn on we purchased ourselves. Later on of course, NASA made this an integral part of the pressure suit."

Astronaut Jim McDivitt quoted in the book All We Did was Fly to the Moon.

The flags were approximately 4x6" and made of nylon. I've compared photos of the suit flags and they appear identical to the 24 GT-4 flown American flags that McDivitt sold several months back. In all likelihood they came from the same batch of flags that the crew purchased before the flight.

All times are CT (US)
