(People talk about '70mm' a lot but it actually measures 65mm. 70mm is only used for projection, the recording medium as used in the camera's measures 65mm. I think this is because the projector film has to carry a sound signal.)

Normal Hasselblad (medium format or 120 film width) is between 60.7mm and 61.7mm. (No perforations!) With the actual picture being a bit smaller because the top and button are used by the camera to lay the film flat.

So you would also need to make two cuts along the entire length of the roll, top and bottom to make it fit.

Then, a slide mount also crops very slightly. Finally, if your roll measures 70mm in width, it means the original Apollo 65mm stock was projected onto 70mm. Then a 120/60mm slide mount will crop even more and you might actually need to cut part of the picture.

Seems a shame to damage such a nice artifact of the pre-digital era of sharing photos.

*Edit: I was wrong, looks like the hasselblad magazines with film canisters as used in Apollo did use 70mm film, not 65mm. The picture size would be normal hasselblad though, so I guess it could fit.
