Leslie Young tries to explain the geometry of the Arrokoth flyby.
"So you have the spacecraft over here, with the orbit normal along this plane. And then MU69 has its rotational axis almost exactly aligned with that, which puts it at 90 degrees to the equatorial plane. Now, for the MIVC scan, we spun the spacecraft in this direction, which means that the Sun must've been over here. Now the asymptote is at 160 degrees outbound, and -- so, you can just invert the matrix, and then you've got the rotational pole. It's simple."
