Drastic changes in Mars South Pole icecap
Cool image time! Summer images taken by Mars Reconnaissance Orbiter 8 years apart of a specific area of the Martian south pole icecap show significant and surprising changes.
The top image on the right was taken August 28, 2007. The bottom image was taken March 23, 2015, four Martian years later. As noted by the science team, the bright flat-topped mesas have shrunk by about half, while the dark rough low areas have grown, eating into the mesa walls.
Closeup study of this area would provide a wealth of knowledge. It will also be very challenging, as the environment is harsh, hostile, and unstable. Imagine doing research in the Himalayas but with an unbreathable atmosphere and temperatures always far far below freezing.
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

Proof of catastrophic anthropogenic interplanetary global warming!
A video about actual climate change, in this case in the Sahara desert and not “climate change” the political agenda where pollution created by economic activity (read; dirty filthy capitalism) and its control is the agenda.
