New close-up photos of the asteroid Vesta from Dawn have discovered numerous bright spots scattered across the face of the asteroid Vesta.

9:07 pm

New close-up photos of the asteroid Vesta from Dawn have discovered numerous bright spots scattered across the face of the asteroid Vesta.

The photos show surprisingly bright spots all over Vesta, with the most predominant ones located inside or around the asteroid’s many craters. The bright areas range from large spots (around several hundred feet across) to simply huge, with some stretching across 10 miles (16 kilometers) of terrain.

The scientists believe the bright spots might be the asteroid’s oldest material, excavated from below by impacts.

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 founder of the Mars Society.

Genesis cover

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 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

After one year in orbit around Mercury, Messenger’s scientists have concluded that Mercury is not only dense but odd.

4:35 pm

After one year in orbit around Mercury, Messenger’s scientists have concluded that Mercury is not only dense but odd.

The [proposed gravity] model, when combined with topography data and measurements of the planet’s spin, reveals that as much as 85% of Mercury’s radius is taken up by its dense iron core — an upward revision. “We knew Mercury had a large core,” says [Maria Zuber of MIT]. “Now we think it’s even larger.” What’s more, to compensate for a crust that’s enriched in sulphur and depleted in iron, the team has proposed a solid shell of iron sulphide that sits between the core and the mantle. While the shell satisfies the gravity constraints, it also makes it more difficult for a lot of convection to occur in the thin mantle that overrides it — which presents problems for those that invoke convection as a driver of the observed tectonic and volcanic features at the surface. “There isn’t a whole lot of mantle to be doing this lifting up,” says Zuber.

Cat purrs prevent heart attacks

7:08 am

Research has now shown that the purr of a cat appears to prevent heart attacks.

A 10-year study at the University of Minnesota Stroke Center found that cat owners were 40 per cent less likely to have heart attacks than non-cat owners. A cat at home reduced the risk of other heart diseases and stroke by 30 per cent.

But then, all cat owners have always known this.

Private space station builder Bigelow is hiring again.

5:47 pm

This bodes well: Private space station builder Bigelow is hiring again.

One interesting tidbit from this article is the description of the company’s negotiations with NASA to attach a Bigelow module to ISS.

The company has been negotiating with NASA for about two years on the potential deal, and that Bigelow has completed various planning and development milestones for NASA. “We’ve been in a series of discussions with NASA over the past two years, with regard to the BEAM project,” Gold told Space News. “They were initiated as part of a proposal in 2010, and we’re hopeful an announcement will be made in the not-too-distant future.”

NASA gave no sign that a deal with Bigelow was imminent. “We do have a no-cost contract with Bigelow to cover early requirements development [for BEAM] but it is not for the flight article,” NASA spokesman Josh Buck said in a March 20 email. “The Agency has not made a decision to go to a flight system yet.” [emphasis mine]

Two years to discuss “planning and development,” and still no decision. My guess is that NASA management doesn’t want to buy a Bigelow module, as it would be relatively cheap and therefore wouldn’t spread much money to NASA centers. They just can’t say no for political reasons.

And if they do want to do it, the slow pace of their decision-making process demonstrates clearly why they shouldn’t be entrusted to build anything in the future.

In testimony before Congress today, the Eisenhower family expressed strong opposition to the design of the Dwight Eisenhower monument.

9:44 am

In testimony before Congress today, the Eisenhower family expressed strong opposition to the design of the Dwight Eisenhower monument.

Although the memorial design was unveiled a year ago, the opposition to it grew louder this winter after grandson David Eisenhower resigned from the Eisenhower Memorial Commission, which selected Gehry for the design in March 2010.

The National Civic Art Society, which has set up an alternative website to the memorial group’s website, outlines its opposition in direct terms. It calls the “tapestry” a “rat’s nest of tangled steel, a true maintenance nightmare.”

[Granddaughter Susan] Eisenhower said the tapestry would collect trash and suggested the design concept is part of the “communist world” of art, adding her grandfather likely “wouldn’t understand it.”

The testimony of the fired JPL employee who is claiming religious discrimination continued on Monday.

8:49 am

The testimony continued on Monday of the fired JPL employee who is claiming the science center fired him because of his religious beliefs.

[David Coppedge] trial’s started last week, and on Monday [he] testified that his supervisor Gregory Chin had wrongly accused him, threatened his freedom of religion and created a potentially hostile working environment. “You are pushing your religion in this office and harassing people with this religion,” Chin said, according to Coppedge, who added: “He was angry and he got angrier.”

Coppedge said he asked Chin why he considered intelligent design anything but science. “Dave, intelligent design is religion,” Chin replied, according to Coppedge. Chin warned him against discussing religion or politics with colleagues, he said.

“I felt threatened .. I said: ‘Greg, this gets into issues of free speech and freedom of religion … this could be construed as creating a hostile work environment’,” he added.

Real scientists should never feel threatened by anything Coppedge was saying, and should in fact enjoy debating the issue. Unfortunately, I have learned that such open-mindedness is found with increasing rarity in modern intellectual society, especially when it comes to Judeo-Christian beliefs. This is why I tend to believe Coppedge’s story.

Scientists have found more evidence that the streaks on Martian hillsides that darken in warm weather are caused by melting groundwater flowing downhill.

8:36 am

Liquid water on Mars! Scientists have found more evidence that the streaks on Martian hillsides that darken in warm weather are caused by melting groundwater flowing downhill.

Last summer, the team pointing the HiRISE camera on the NASA Mars Reconnaissance Orbiter (MRO) dropped that bombshell: it had identified 7 confirmed and 12 likely sites that contained hundreds of narrow streaks on steep slopes inside crater walls. During warmer seasons, as temperatures rose as high as 27 degrees Celsius, the streaks darkened, and then faded again. Salts could allow brines to be liquid at these temperatures. Today at the Lunar and Planetary Science Conference in The Woodlands, Texas, the HiRISE team announced that it now has doubled it stash of streaks, with the identification of 15 confirmed and 23 likely sites, all in the mid-latitudes of the Southern Hemisphere.

Additional analysis of the spectrographic data also suggests that water could be the cause of the darkening.

The Met Office in the UK has issued an updated temperature record for the past 150 years, suggesting that the climate has warmed 0.75 degrees Celsius since 1900.

The Met Office in the UK has issued an updated temperature record for the past 150 years, suggesting that the climate has warmed 0.75 degrees Celsius since 1900.

I remain suspicious of this announcement, as the scientists issuing this report are the same scientists who participated in climategate, including Phil Jones of the Climate Research Unit of East Anglia University. With that in mind, before I will believe these numbers I will wait for some vetting of this new data by those who have shown themselves to be a bit more skeptical, a bit more open-minded, and a lot more honest.

One more point: to really understand the importance of an increase of 0.75 degrees Celsius over 112 years, we would need some context, something this news article does not give us. For example, how do these numbers compare with the numbers predicted by the various climate models? Also, this is the overall change. How have things changed from year to year? Is there any evidence in this data for a cooling during the past decade, as indicated by other climate measurements?

Scientists have published the first complete global geological map of the Jupiter moon Io.

11:22 am

Scientists have published the first complete global geological map of the Jupiter moon Io.

The highly detailed, colorful map reveals a number of volcanic features, including: paterae (caldera-like depressions), lava flow fields, tholi (volcanic domes), and plume deposits, in various shapes, sizes and colors, as well as high mountains and large expanses of sulfur- and sulfur dioxide-rich plains. The mapping identified 425 paterae, or individual volcanic centers. One feature you will not see on the geologic map is impact craters. “Io has no impact craters; it is the only object in the Solar System where we have not seen any impact craters, testifying to Io’s very active volcanic resurfacing,” says Williams.

You can download the map here.
