"From what we know of the heat flow coming from interior, there's no reason that this stuff cannot be going on today," said New Horizons' Bill McKinnon (source).
If the surface is made of ice, is it possible that asteroids hitting would melt the ice and then it just levels itself out before freezing over again?
Just wondering.

Here in an Arxiv.org paper discussing predictions for the New Horizons pass, made in January.

Tidal heating by the Sun is possible to to interactions with Charon's gravity.
| Possible scenarios that the New Horizons spacecraft may find in its close encounter with Pluto Pluto and its moon Charon have trapped rotation, i.e., both bodies show each other the same hemisphere. On the other hand the orbit of Charon is circular (and therefore so is Pluto’s orbit around their common centre of mass) (Buie et al., 2012). For these two conditions it is not expected that there is an exchange of energy, via tides, between the two bodies. However, solar gravity force modifies this view since Charon may be in conjunction, in opposition, square and all intermediate positions with respect the Sun, thus both bodies will exert on Pluto a continu ous changing tidal force that implies a continuous, and periodic, deformation of Pluto’s body (and of course Charon’s body). This continuous exchange of energy in tidal forces produces heat due to dissipation of tidal energy. The heat flow may manifest its elf in cryo -*‐ volcanic activity on the surfaces of both bodies, or in the presence of a molten layer in their interior, or both |

Meteor impacts, by themselves, are not likely to generate much heat on Pluto's surface. On the surface of Pluto the ice is frozen nitrogen, carbon monoxide and methane. Nitrogen may even be liquid below the surface, where it is not as cold. Water ice is thought to exist under the surface, but unlike water ice, frozen nitrogen is able to flow (albeit slowly):
These flows are able to fill in and cover craters on the surface:

I think that he took you seriously. :chuckle:
I would not recommend taking Stripe seriously. :chuckle:

Ah, Stripe.
Such irony... :chuckle:
Actually, the links I've posted pertain directly to the conversation discussed in the OP. Feel free to ask questions, I'll be happy to answer them.
We should ask you questions? :darwinsm:
How about the myriad of issues that have been raised in this thread that you've actively ignored?
Get to those. :up:
On the contrary, Pluto is heavily cratered:
A number of other craters and features have been covered by icy flows of nitrogen.

Nope. It's lightly cratered. The predictions were that it would be heavily cratered.
Darwinists love making post-fact predictions.
