How did Tim Peake get full Earth in his helmet picture? [convex mirror illusion]

There are similar images on this link

How is it possible to capture a full Earth which is 12,000km in diameter a mere 400km up in the sky.

You're not seeing the "full Earth". You're seeing a very small portion of the Earth, projected onto a sphere.

Take a look at the reflections of any other object in a space helmet. The visor is basically spherical so it will reflect a very wide angle of view, effectively acting like a fisheye lens.

This photo was taken during an EVA outside the space shuttle, and the nearby surface again looks like a "ball".

The Shuttle heat shield actually looks like this:

In the Earth images above, note the appearance of the clouds. It's obvious that you're only looking at a small part of the Earth, not the whole planet.

That ball does look very similar to the original however you can clearly see it gets your house and then stops and I'm sure your actual field of view can see neighbors which is omitted in your example

Maybe swap angles to see if you can actually get your entire field of view on that ball bc that's the only full working analogy

The ball held up in the air (with the camera below it) reflects the entire 360 degrees of the horizon, which is the same was what is happening in the helmet shot.

The "horizon" as seen from the ISS is only a very small part of the Earth, albeit a lot larger than the horizon as seen from Mick's garden. If you looked at it with the naked eye, rather than in the reflection of the helmet, it would look more like this:

This is roughly the same view on Google Earth, and you can see that you're only looking at a pretty small area of the globe: Florida and parts of the Caribbean and Gulf of Mexico:

I think I can do a virtual dynamic illustration of the phenomenon if anyone is interested. Basically what Mick already did except I can do it more illustrative.

Okay, here is the animation previously mentioned.


It basically demonstrates the same thing as @Mick West's previous example, except that it shows how the reflection of the environment will change according to the curvature of the surface.
