NASA narrows to three the Mars rover landing sites in 2020
Scientists have now narrowed to three the candidate landing sites for NASA’s 2020 Mars rover mission.
The three sites include Jezero crater, which was once home to an ancient Martian lake and which could preserve the remains of microbial life, if it ever existed on Mars. “You’ve got a large river bringing water and sediment into a very large lake, comparable to Lake Tahoe,” says Timothy Goudge, a planetary scientist at the University of Texas at Austin. Jezero scored highest on a community vote of scientists attending the workshop.
Other possible targets include Northeast Syrtis, where hot waters once circulated through the crust and could have supported life, and Columbia Hills, the area explored for years by NASA’s Spirit rover.
From the Nature article above as well as this Science article, it sounds like the Columbia Hills choice is unlikely. The Science article pushes Jezero crater, which had the most votes at the workshop and is shown in the image on the right.
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
