I guess the best word I can think of here is "ironic".
Hayabusa 2 was planned with three sample acquisitions in mind, with the idea of getting diverse samples. But Ryugu turned out to appear fairly homogeneous so now they are only planning one sample (what about the sub surface sampling though? But I digress... ). Then you have OSIRIS-REx only planning one single sample grab from Bennu. I know they haven't reported anything yet about any of Bennu's compositional differences but, well... just look at it. Technically, they could make three tries at sampling, provided the canister didn't fill up on the first try, so I wonder if they might rethink things. Also, I'm a little worried at this point. OSIRIS-REx seems to be counting on there being dust and small pebbles for its sampling. It is still too far from Bennu to tell, but if the surface turns out to be like Ryugu with nothing but larger pebbles and rocks available, I wonder how they will deal with that. |
