NASA is trying to shake loose Martian fossil bone tissue

Fig. 1 shows nine arrows pointing to vertical blood vessel remains in
nine fossil osteons ( bone tissue) in a trench named Snow White. NASA
says the white color area is where water ice is, although it is non-
continuous and very small in size. NASA plans to scoop up the water
ice there on July 8 to put it into an oven for testing. As the soil
(containing water ice) is unusually clumpy, NASA plans to shake the
soil until it passes the 1mm holes of a screen above the oven, just
as NASA did last time.
Such shaking could damage related instruments. Have you heard of
shaking loose bone tissues, fossilized or not? Couldn't NASA find
someone who knows about bone basics?
