Saturn’s moon Epimetheus
Cool image time! The picture on the right was taken by Cassini on December 6, 2015, and shows the asteroid-like misshapen moon, too small (only 70 miles across) for gravity to force it into a sphere. Behind it, filling the frame, is gigantic Saturn.
If you look close, you can see one crater that appears elongated, as if the impact was only a glancing blow.
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

What if that elongated crater was actually some sort of subsidence? Might it deform existing craters within it in a way that is similar to what we see?
