New close-up photos of the asteroid Vesta from Dawn have discovered numerous bright spots scattered across the face of the asteroid Vesta.
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.
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 or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

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.

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

The Russians want to do this badly, and have been pressing NASA to go along, with no luck, for more than a decade. That it took that long for NASA to finally realize the need tells us much about the American space agency.

Private space station builder Bigelow is hiring again.
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.
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 scientists throw in sea level rise as a contributing factor, but don’t really have good data to prove that. Moreover, sea level rise cannot account for the tilt.
