The results confirm Vesta as the source of a specific family of asteroids, but more interestingly also identify the actual impact that peeled these asteroids from Vesta’s surface.
Read the whole thing, Dawn has found a lot of interesting stuff.

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, 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 you don't support the big tech companies and the author gets a bigger cut much sooner.

"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.

The first solar eclipse to cross the continental United States in two decades will occur on May 20.
Set your calendar: The first solar eclipse to cross the continental United States in two decades will occur on May 20.
An annular solar eclipse occurs when the moon passes between the earth and sun, but the lunar disk does not completely block out the sun and instead leaves a “ring of fire” visible around the moon at the point of maximum eclipse. Most anyone west of the Mississippi will see a partial eclipse, but the real treat will be for those located in the 200-mile wide path of the eclipse which will trek east from the California / Oregon border through Nevada, Utah, Arizona, New Mexico, and finally set below the horizon in west Texas.
Remember, you will need good eye protection if you choose to look.

ATK today announced that it is building its own manned capsule for its Liberty solid rocket.
The competition continues to heat up: ATK today announced that it is building its own manned capsule for its Liberty launch system.
The capsule’s first two flights are scheduled in 2014, both abort tests, followed in 2015 by an orbital flight and, finally, a crewed orbital flight. The spacecraft is designed for ten flights each, and ATK plans to build a minimum of four capsules. All flights will be launched by the Liberty launcher, and ATK is not actively exploring adapting the capsule for other [launch vehicles].
Liberty is based on the upgraded shuttle solid rocket boosters that were developed for the Ares rocket, now cancelled.

An Indian tribe has sued and three researchers have countersued over possession of two 10,000-year-old skeletons unearthed during construction in San Diego.
Fighting over bones: An Indian tribe has sued and three researchers have counter-sued over possession of two 10,000-year-old skeletons unearthed during construction in San Diego.
Not surprisingly, the problem here stems from a poorly written federal law amended by a bureaucratic rule in 2010 that gives any Indian tribe control over any ancient human bones found in the U.S., even if those bones come from a human that lived long before the tribe even existed.

One astronomer has found that the habitable zone around some smaller stars is smaller than first calculated because of tidal heating.
One astronomer has found that the inner edge of the habitable zone around some dwarf stars is smaller than first calculated because tidal forces overheat planets close to the star.
Then again, this heating might expand the habitable zone in other directions. Stars might overheat when close to the star, but get a boost of needed heat when they would normally be too far away.
