Images from Curiosity have spotted some unexpected geology in Gale Crater.

A mosaic of high-definition images of Mount Sharp, the central peak dominating the landing site at Gale Crater, reveals tilted strata never before seen on Mars. The strata dip downwards at an angle close to that of the slope of the foothills of the 18,000-ft. tall mountain within which they are formed.

“The cool thing is the cameras have discovered something we were unaware of,” says mission chief scientist John Grotzinger. “This thing jumped out at us as being very different to what we expected,” he adds. Lying in the low-lying foothills beyond the dune field between the rover and the base of Mount Sharp, the inclined layers are a “spectacular feature” that could not be seen from orbit.

I think there are two reasons these tilted layers are puzzling scientists.

One reason why Neil Armstrong got the job

6:01 pm

An evening pause: This short clip from the Discovery Science series Rocket Science illustrates one reason Neil Armstrong got the job to land the first spacecraft on the Moon, even though it shows Armstrong crashing his test vehicle!

The man was cool-headed. Not only did Armstrong not panic when a thruster failed, he kept trying to regain control of the craft until the last moment, ejecting less than a second before impact. Then, he was calm about it afterward, hardly mentioning the incident to others.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Neil Armstrong

2:04 pm

I think the gracious statement by Neil Armstrong’s family sums up his life quite well.

We are heartbroken to share the news that Neil Armstrong has passed away following complications resulting from cardiovascular procedures.

Neil was our loving husband, father, grandfather, brother and friend.

Neil Armstrong was also a reluctant American hero who always believed he was just doing his job. He served his Nation proudly, as a navy fighter pilot, test pilot, and astronaut. He also found success back home in his native Ohio in business and academia, and became a community leader in Cincinnati.

He remained an advocate of aviation and exploration throughout his life and never lost his boyhood wonder of these pursuits.

As much as Neil cherished his privacy, he always appreciated the expressions of good will from people around the world and from all walks of life.

While we mourn the loss of a very good man, we also celebrate his remarkable life and hope that it serves as an example to young people around the world to work hard to make their dreams come true, to be willing to explore and push the limits, and to selflessly serve a cause greater than themselves.

For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.

“My healthcare plan I put in place in my state has everyone insured.”

1:52 pm

Romney on Thursday: “My healthcare plan I put in place in my state has everyone insured.” Also, it is an “important accomplishment” that is “working, by and large, pretty well.”

Oy. Romney apparently still does not realize that Romneycare is as politically toxic as Obamacare, which probably explains why he has not been able to pull ahead of Obama in the polls. It also once again explains why Republicans looked long and hard for an alternative before finally settling on Romney.

Nonetheless, Romney has been very clear about his opinion of Obamacare itself. He considers it an improper overreach of the federal government and a bad law. He has also been very clear about what he will do about it once in office: Repeal it. For this reason, voters will eventually choose him, even if the moment they finally make that choice will be in the voting booth on election day.

The artist who sculpted a secret message in code — in plain view in the courtyard of CIA headquarters and unsolved now for twenty years — has now provided codebreakers a tiny clue to its solution.

The artist who sculpted a secret message in code — in plain view in the courtyard of CIA headquarters and unsolved now for twenty years — has now provided codebreakers a tiny clue to its solution.

The final mystery of Kryptos – it means “hidden” in Greek – is known as the “Everest of codes” among the thousands of cryptographers who are obsessed with deciphering it. … Three passages were unravelled in 1999. But the fourth and toughest remains defiantly obscure, to the surprise of nobody more than Jim Sanborn, the sculptor who created the enduring puzzle.

NASA today announced that recent research on ISS into bone loss due to weightlessness has found that proper exercise and diet can stabilize bone loss.

11:42 am

Good news! NASA today announced that recent research on ISS into bone loss due to weightlessness has found that proper exercise and diet can stabilize bone loss.

Past Russian research on Mir had found that exercise and diet could limit the bone loss, but not stop it entirely. The key difference in this recent work seems to be the use of more sophisticated exercise equipment.

If this research holds up, it eliminates one of the most serious obstacles to interplanetary travel.

Todd Akin, whose stupid comments about rape have practically destroyed his campaign, is receiving death threats to himself, his family, and his staff.

9:41 am

Modern political civility: Todd Akin, whose stupid comments about rape have practically destroyed his Senate campaign in Missouri, is receiving death threats against himself, his family, and his staff.

I don’t know if the threats are coming from either the left or the right. The left kind of wants Akin to stay in the race so that Claire McCaskill has a better shot at winning. Yet, the left has also been quite willing in recent years to express and even commit violence against their opponents. For these kinds of death threats to come from the left would not be unusual or surprising. The right meanwhile is furious at Akin, mostly because of the absolute stupidity and ignorance exhibited by his comments. It is likely that the comments will cost them an easy Senate win, which in turn might cost them control of the Senate. Yet, threats of violence from the right are rare.

Thus, it is hard to say what politics might be instigating these threats.

It really doesn’t matter. The threats are horrible, and are far worse than anything Todd Akin said. I hope the police find and arrest every single person who sent a threat.

Romney’s energy policy proposal announced today would redirect science funding towards basic research.

5:51 pm

Mitt Romney’s energy policy proposal, announced today, would redirect science funding towards basic research, according to this mostly positive analysis from the generally liberal journal Science.

Personally I’d like to get the federal government out of all this. Let the private market decide where the money should be spent for research. Moreover, we still have that federal debt to pay off. Where will Romney get the money?

New ice core data from Antarctica suggests in the past 10,000 years temperatures have often been higher than today, and that the rise in temperatures during the past 100 years is also not unprecedented.

12:37 pm

The uncertainty of science: New ice core data from Antarctica suggests that in the past 10,000 years temperatures have often been higher than today, and that the rise in temperatures during the past 100 years is also not unprecedented.

These results are actually not news. Climate scientists have known for decades that today’s climate is not unique, and that the Earth has gone through similar temperature fluctuations in the past. The results simply reconfirm this fact, and make any global warming claims to the contrary less believable.
