New Horizons mission made the first rendezvous in history with a Kuiper Belt Object (KBO). About thirty minutes after the probe conducted its flyby of Ultima Thule (2014 MU69), the mission controllers were treated to the first clear images ever taken of a KBO.
Since the first approach photographs were released (which were pixilated and blurry), the New Horizons team has released new images from the spacecraft that show Ultimate Thule in color and greater detail.
Meet #UltimaThule! What you’re seeing is the 1st contact binary ever explored by a spacecraft. This object, which we can now see is a contact binary, used to be 2 separate objects that are now bound together.
