Osiris-Rex just touched Bennu with its sampling tool.
They just wrapped up a news conference on nasa-live. They still don't know how large a sample they got. Something that surprised them was that the rocks they touched crushed easily. They weren't like Earth rocks at all. Just dust grains kind of clumped together to resemble rocks but seemingly not cemented together very well.
