Ancient but not unchanged
This is great and a leap for science. Brilliant and look forward to seeing the images.
But why are these rocks in space described as "ancient" and "unchanged" that could "explain how the solar system was formed". Sorry, but the Earth is also 4+ billion years old and these rocks experience bombardment by other rocks and solar particles and radiation as well as interstellar radiation, so they can hardly be described a "primeval" and as "when the solar system was formed". Yes, they won't have experienced weathering like the Earth does, but still, it is a mistake to assume that they are essentially unchanged. The other thing is that conditions in the Kuiper belt may not be anything like the conditions the Earth experienced in its formation.
