foldable map of Ida Options

[chuckclark]

Here is a constant-scale natural boundary map of Ida that folds to a decent replica of the asteroid. Map edges are Ida's major ridges.[attachment=16299:Ida_MaxRidge_post.jpg]
[EDIT] Here it is again with the photomosaic properly credited; apologies to M. Nyrtsov for my oversight.

Here are the Phobos slices. As I don't know how they will be used, I left them in 3D space. They are 0.3 km's apart.

Here are the Phobos slices. As I don't know how they will be used, I left them in 3D space. They are 0.3 km's apart.

Well, here's what I think: cutting all those slices out of something looks like a real pain in the old asteroid, so to speak; and even if I had a laser cutter and matched sheet thickness to the appropriate scale, I'm sure I have the technical wherewithal to glue them all together evenly.
Surely that's not how you made (I'll stick with Ida as topic, but same applies to Phobos) this model, right? However this got made is the way to go, for good solid 3D models.
Even the original Eros models (the NEAR team had) used the assembled-slice method only to make a master object, then it was in turn used to make a mold, from which the production run was cast.

And yet all these methods leave us wanting the photomosaic imagery in real space, not just in the computer where we can't get our hands on it. Whence the advantage of foldable constant-scale natural boundary maps, with the disadvantage they're so easy to dent, if not crush.
So see next post for the rest of what I've come up with.
