AP3 will allow scientist to study the atmosphere. Things like searching for clouds and hazes in the atmosphere. Other things like ultraviolet emissions from nitrogen, oxygen, hydrogen, and other species in the atmosphere will be studied. During both AP2 and AP3 the mission directors will have to be on the lookout for harmful debris that could mess up the trajectory of the ship. The current prediction of the odds of running into such a problem is below one-percent. Just in case, measures have been put in place to protect the spacecraft. Backup plans have not only been prepared but they have also been tested. The Near Encounter Phase is on the two days surrounding the closet encounter. The expected result will be maps and atmospheric data. As the ship recedes from Pluto, it will study the backlit atmosphere to see more sensitivity of hazes and rings. After the Pluto fly-by is finished, the hope will be to see one primitive object in the Kuiper Belt (Stern
