More Martian pimples
In a captioned image release last week from the science team of the high resolution camera on Mars Reconnaissance Orbiter (MRO), planetary scientist Alfred McEwen describes a string of mounds aligned and deformed by a fissue.
The image, cropped and reduced to post here, is to the right. As McEwen notes,
A possible geologic interpretation is that as the rift began to open, subsurface material (perhaps mud) erupted to create the mounds, which were then deformed as the rift continued to spread.
Located in Chryse Planitia, the region of the northern lowland plains just north of the outlet from Valles Marineris, these mounds and their probable geological origin seem very similar to the pimple mounds I highlighted in a cool image only last week. The only difference is that the earlier posted pimples were not aligned with any obvious fissure or rift.
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
