More evidence found for liquid water on Mars
A new study suggests that a liquid but very salty water does appear on Mars, during the night in the winter and spring months.
The team used Curiosity’s weather-monitoring equipment to look for those conditions and found that they occur every day in months throughout winter and spring. They suggest that overnight and before sunrise, some of the frost that forms on the planet’s surface interacts with the strong salts and turns liquid, seeping into the soil. This lines up with previous studies, which have detected geographic features that suggest flowing water.
The results come from the Gale Crater, which is itself too cold to support microbial life — even with liquid water present. But the study authors believe this phenomenon could occur anywhere on the planet, and may actually be more common in areas closer to the polar regions. Still, Mars is a pretty desolate place, and the amount of water we’re talking about is minimal at best. “There’s so little water that you can’t even see it visibly,” Morten Bo Madsen said.
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
