Pluto's interacting surface and atmosphere
Dr. Leslie Young - New Horizons Science Team SETI Talk sept. 2016 : https://youtu.be/srEmXQJoln8 Description: Pluto's main atmospheric species, N2, is also frozen on its surface, as are its minor atmospheric species, CH4 and CO. The New Horizons spacecraft found complicated and intriguing evidence for a dynamically interacting surface and atmosphere. The REX instrument shows a planetary boundary layer that depends on whether there's N2 ice available to sublimate. Altitude appears to be a factor in the distribution of both N2 and CH4 ice, with N2 favoring lower altitudes (higher pressures, so higher condensation temperatures), whereas some high ridges are coated in CH4 frost. Sublimation may be responsible for some of the stranger geologic forms on Pluto. Finally, preserved landforms may point to earlier ages with more widespread volatile ice coverage or higher surface pressures. Dr. Young will talk about the evidence, and some of the ways New Horizons is influencing how we think about Pluto's atmosphere and surface. . |

Incredible! Thank you so much for sharing this. Also, I would like to thank you and your team again for exploring the Pluto system and Kuiper Belt.

Pluto article by Emily Lakdawalla
DPS/EPSC update on New Horizons at the Pluto system and beyond The first image contains some terrain that I don't remember seeing before. And possibly another volcano.

WOW !! WOW !!! Thanks a lot for those useful links : what an IMPRESSIVE work of yours and your team !!! What a SPECTACULAR new world you discovered ! The New Horizon mission success deserves indeed a lot of CONGRATULATIONS !  (PS : as a TPS member since 1982, I've been following your Pluto projects since the very beginning : you did a great feat convincing people and getting a budget for this incredible one-shot mission !) |

Thank you, its amazing how long and hard we had to work to get this mission on the books, and then to build and fly it. But really it was the work of many people, no one. Spaceflight is a team sport. -Alan S. |

Icarus
Volume 287, Pages 1-334 (1 May 2017) Special Issue\: The Pluto System  Pay-walled I remember and open access issue before the encounter with articles about what was 'known' up to that point. I had hoped that this would be the same. |
