Thought about how much of Pluto will remain relatively unmapped. Apparently the close flyby captured about half. When the probe approached from the side, and now is leaving, we get som decent pictures from areas not visible during the close flyby, but they will gradually become coarser. Pluto's rotational period is 6.4 days, which helps capturing almost everything, more or less.
Wonder what the quality of the photos giving the least detals will be. Apparently they could come from the side which was opposite during the close flyby.
A fresh batch of images straight from the New Horizons downlink give us just what we’ve been waiting for: color views of Pluto! Ridiculously high resolution detail! Strange new snakeskin textures! Plus a first look at how methane is involved in shaping these crazy ice landscapes.
These new images from NASA’s deep space probe mean we’re going to need to write yet another chapter in the evolving saga of confusing geomorphology on the wee dwarf planet.
The colours aren't fake as such, they have exaggerated some to make them more clearly visible as well as bring some invisible light down into the visible light spectrum

The unusual feature is one of two possible ice volcanoes, also known as cryovolcanoes, spotted on Pluto by the New Horizons spacecraft.
Unlike volcanoes here on Earth, these would have erupted with an icy mix of frozen water, ammonia, methane and/or nitrogen.
The suspected ice volcanoes on Pluto resemble shield volcanoes; rather than rising to a sharp peak, they are longer and lower, like a shield.
The feature in this image has been named Wright Mons, for the Wright Brothers, and is 2.5 miles high by 90 miles across. It's located just below the famous "heart" on Pluto.
Since there is only one impact crater on Wright Mons, NASA scientists believe it may have been active relatively recently.
"Nothing like this has ever been seen in the outer solar system," New Horizons scientist Oliver White told Reuters in November when the ice volcanoes were first announced.
