#itokawa — Public Fediverse posts

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.

A paper showing "that rubble pile #asteroids can survive ambient solar system bombardment processes for extremely long periods and potentially 10 times longer than their monolith counterparts", based on three regolith dust particles recovered by the #Hayabusa space probe from the rubble pile asteroid 25143 #Itokawa: https://eprints.gla.ac.uk/290972/1/290972.pdf -> ¿Y si los asteroides pila de escombros fueran casi indestructibles?

‘Puin’-asteroïden zijn verrassend lastig te vernietigen

Een onderzoeksteam denkt dat zogenaamde puin-asteroïden lastig zijn te vernietigen en dat ze zeer algemeen in ons zonnestelsel voorkomen.

The study’s results showed #asteroid #Itokawa, which is 2 million kilometers from Earth and around the size of Sydney Harbour Bridge, was hard to destroy and resistant to collision.

"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"
