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.

A bad day for Obama and the Democrats.
As I’ve said repeatedly, the 2010 elections were not a fluke, but a trend. The public intends to fire this President and those in Congress — from both parties — who have put the U.S. on verge of bankruptcy.

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.

In related news, a prison inmate has gotten the highest percentage of votes, 40 percent, of any candidate in any previous state primary against Barack Obama.
Washington politicians had better stop ignoring the fiscal concerns of the tea party. The federal budget has got to be brought under control.

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.

Richard Rogers – Edelweiss
An evening pause: From The Sound of Music (1965). The context: The Nazis have taken over Austria, and plan to arrest Captain Georg Ludwig von Trapp and his family at the end of this concert. This lovely song, Edelweiss, is initially sung by von Trapp as a farewell to his nation. As the song unfolds, however, it becomes instead a song of defiance against the Nazis, by the von Trapps and the audience.
Always, always, we must stand for freedom.

Astronomers now believe that Type 1a supernovae — used to discover dark energy — can be produced in two different ways.
The uncertainty of science: Astronomers now believe that Type 1a supernovae — used to discover dark energy — can be produced in two different ways.
Type Ia supernovae are known to originate from white dwarfs – the dense cores of dead stars. White dwarfs are also called degenerate stars because they’re supported by quantum degeneracy pressure. In the single-degenerate model for a supernova, a white dwarf gathers material from a companion star until it reaches a tipping point where a runaway nuclear reaction begins and the star explodes. In the double-degenerate model, two white dwarfs merge and explode. Single-degenerate systems should have gas from the companion star around the supernova, while the double-degenerate systems will lack that gas.
For astronomers, this possibility raises several conflicting questions. If two different causes produce Type 1a supernovae, could their measurement of dark energy be suspect? And if not, why is it that these two different causes produce supernovae explosions that look so much alike?

Massachusetts state officials are restricting the kinds of foods that can be sold at bake sales.
We’re here to help you: Massachusetts state officials are restricting the kinds of foods that can be sold at bake sales.
Bake sales, the calorie-laden standby cash-strapped classrooms, PTAs and booster clubs rely on, will be outlawed from public schools as of Aug. 1 as part of new no-nonsense nutrition standards, forcing fundraisers back to the blackboard to cook up alternative ways to raise money for kids.

Scientists have found that a solar Grand Minimum 2800 years ago might have caused a period of cooling in Europe.
The evidence for this link is at this moment slim, based upon a single data point from a lake in Germany. Nonetheless, it is further evidence that the Sun’s production of sunspots is more important to global climate than climate scientists had previously believed.
