The New Horizons engineering team has brought the spacecraft out of hibernation to begin preparations for its January 1 2019 flyby of Kuiper Belt object 2014 MU69, which they have dubbed Ultima Thule.

New Horizons will begin its approach phase of the MU69 flyby on August 16, 2018, when it will begin imaging MU69 and the area around it to begin acquiring data about the KBO and its surroundings. Also, New Horizons will look for potential debris that could pose a hazard to itself, such as moons or rings.

Should any potential dangers be found, New Horizons has four planned opportunities to make trajectory changes from early October to early December 2018. The backup trajectory has a distance from MU69 of 10,000 kilometers (around 6,200 miles). Using the backup trajectory would lead to less and/or lower-quality science data gathered due to the probe flying by MU69 further away than planned.

The approach phase will last from August 16 to December 24, 2018, after which the core phase will begin.

The core phase begins just one week before the flyby and continues until two days afterward. It contains the flyby and the majority of the data gathering.

Based on this schedule, we should begin to get some interesting pictures of Ultima Thule by the fall.
