This is the original NASA emblem.
"This smaller white-bordered version of the NASA vector patch is clearly visible in this photo on suit tech Joe Schmitt's hat during suiting-up activities prior to the Apollo 11 launch.
Ed Mitchell is also pictured wearing this patch on a flight suit in this photo taken of the Apollo 10 backup crew during training.
What appears to be a similar patch is also visible on Jim McDivitt's coveralls in a NASA publicity film made prior to the launch of Apollo 9. The image is not very clear but the fine details look a little different from the version shown above."
