Cassini’s last close-up images of Dionne
Cool image time! NASA has released images from Cassini’s Monday close fly-by of Saturn’s moon Dionne.
The press release itself did not include any of the close-ups for some reasons. You have to dig for them at the site. Go here, here, here, and here to see a few of more interesting, the first of which is a global view taken just before the fly-by. The second is the highest resolution image, with a resolution 10 feet per pixel. The third shows the nighttime surface lit entirely by reflected light from Saturn. The fourth, shown on the right, was taken from an altitude of 470 miles with a resolution of 150 feet to the pixel. It shows the moon’s rolling, pock-marked, and cratered surface, to the horizon.
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
