Rosetta spots no surface ice on comet
The first results from Rosetta’s ultraviolet spectrograph find the surface of Comet 67P/C-G to be surprisingly lacking in exposed ice patches.
The lack is unexpected, considering that this same instrument has also detected evidence of water in the comet’s coma.
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 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

Gee, there is a surprise… ?? lol.
Not surprised at all. These videos explains why there is no ice and why their instruments detected water in the coma of the comet.
