More Pluto news!
At a press conference today Alan Stern led off by dubbing Pluto-Charon as a “double planet system”. Some new results:
- Tombaugh Regio (the heart) has been identified as a region of carbon monoxide.
- The atmosphere extends out to about 600 miles. It is comprised of hydrocarbosn, methane, and nitrogen, with nitrogen the main component. It is naturally escaping from the planet, ionized by the solar wind. The consequence is that a substantial amount of Pluto has evaporated away over time. The numbers are not yet quantified, but will be as more data arrives.
- The images once again suggest significant activity over time, both of erosion and tectonic processes. One flat plain, dubbed Sputnik Planum, is what one scientist described as “difficult to explain terrain.” The image is to the right. Some of its features resemble icecap glaciers, which are formed by processes that do not exist on Pluto. There also appear to be wind streaks on this planum!
- They have named a mile high mountain has been dubbed Norgay Montes after the man who accompanied Edmund Hillary to the summit of Mt. Everest.
As the scientists warned today, every conclusion right now is very speculative, and should be taken with a very big grain of salt.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Taking a very detailed snapshot of a small region is great, but is anyone plastering this onto google Pluto?
Taking into consideration that Pluto is now in “winter”, who knows what the place was up to during the height of its “summer”.
