An Enceladus close look
Cool image time! The image on the right is the first processed close-up image released from Cassini’s fly-by of Saturn’s moon Enceladus on Wednesday. The resolution is about 50 feet per pixel, taken from about 77 miles away. This surface, in the general area where Enceladus vents lie, reminds me of a thick field of snow that has begun to melt away.
Since the fly-by got within 30 miles, even higher resolution images should follow.
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

Like the crusty late winter snow that has melted and froze after repeated snows and rains.
