Guidance, navigation, and control testing for the #HeraMission is using, among other things, a 3D print of a scaled model of the asteroid #Itokawa as a stand-in for the asteroid #Dimorphos - despite their quite different shapes: https://www.esa.int/Space_Safety/Hera/Virtual_flying_lessons_for_Hera_asteroid_mission .

But I am aware of previous imaging tests on other projects that used random machine parts to represent a rock pile.

So this is a fine choice.

Virtual flying lessons for Hera asteroid mission

As ESA’s Hera spacecraft for planetary defence goes through pre-flight testing, the system that will steer it around its target binary asteroid system is also undergoing its final checks for space.

"The samples from asteroid 25143 Itokawa include not only ordinary chondrite material but also cubanite, a copper-iron-sulfide rare in the meteorite record and likely formed on a different parent body"

Hinweis zur Erdgeschichte: Überraschend Wasser auf Asteroid Itokawa gefunden

In kleinsten Partikeln vom Asteroiden Itokawa haben Forscher Spuren von Wasser gefunden. Das sehen sie als Hinweis auf die Geschichte des irdischen Wassers.
