Hubble tracks the aftermath of a possible asteroid collision

10:05 pm

Using the Hubble Space Telescope over the last ten months, astronomers have tracked the decaying aftermath of a possible asteroid collision. Key quote:

Astronomers think a smaller rock, perhaps 10 to 15 feet wide, slammed into the larger one. The pair probably collided at high speed, about 11,000 mph, which smashed and vaporized the small asteroid and stripped material from the larger one. Jewitt estimates that the violent encounter happened in February or March 2009 and was as powerful as the detonation of a small atomic bomb.

The image sequence below, taken from the original paper describing the discovery [pdf], shows the slow changes that have occurred since January. At the moment scientists do not have an satisfactory explanation for the nucleus’s X-shaped pattern in the earliest images.

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.

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.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount.

We won’t release our contributors because the adminstration will then harass them

2:43 pm

Is this how a government in a free society functions? The Chamber of Commerce won’t release its contributors because they fear the administration will harass and threaten them. And they have experience to back that fear up. Key quote:

What this administration wants is a list of who the companies are who are contributors, and we saw last year . . .when we very publicly ran ads against the Patients Protections and Affordable Care Act . . . there was an attempt to try and find out who were the corporations that were contributing to that effort. When some of those corporate names were divulged, not by us, by others, what did they receive? They received protests, they received threats, they were intimidated, they were harassed, they had to hire additional security, they were recipients of a host of proxies leveled at those companies that had nothing to do with the purpose of those companies. So we know what the purpose here is. It’s to harass and intimidate. [emphasis mine]

That the White House and President Obama are right now willing to accuse their opponents of all manner of evils (taking money from foreign governments) without any evidence is further evidence that there are reasons to fear them.

EPA Funnels Taxpayer Money to Dozens of Liberal Community Activist Groups

10:29 am

Proof that the Environmental Protection Agency (EPA) has more to do with propaganda and politics than regulation: “EPA funnels taxpayer money to dozens of liberal community activist groups.” I especially like this one:

A grant recipient in Appalachia — the heart of coal country — will teach households in Franklin County, Ky., how to reduce household greenhouse gas emissions. The project called “Lighten Up, Frankfort!” will use the book “The Low Carbon Diet” to guide households through a series of actions to reduce their household energy use. The actions include “empowering” people to “lose unwanted pounds.”

APS responds to Harold Lewis’s resignation letter

10:16 am

The American Physical Society has responded to Harold Lewis’s resignation letter.

It appears from their response that they are feeling some pressure about their past position, which stated “The evidence is incontrovertible: Global warming is occurring.” Compare that with what they say now, in their response to Lewis:

APS continues to recognize that climate models are far from adequate, and the extent of global warming and climatic disruptions produced by sustained increases in atmospheric carbon loading remain uncertain.

How nice. A science organization recognizing the uncertainty of science!

The World’s First Everything-Proof Underground Luxury Community

2:59 pm

The world’s first everything-proof underground luxury community. Fun quote:

The Barstow bunker was built to withstand a 50-megaton nuclear blast 10 miles away, 450mph winds, a magnitude-10 earthquake, 10 days of 1,250°F surface fires, and three weeks beneath any flood. Vicino says that a soon-to-be-installed air-filtration system will also neutralize any biological, chemical or nuclear attacks. The Barstow branch will stock enough food and clothing to sustain 135 people for at least a year, and in a lifestyle that Vicino describes as compact but luxurious, like being on a cruise ship.

The state of NASA’s commercial crew program

10:05 am

The state of NASA’s commercial crew program. Key quote:

The Obama administration requested $3.3 billion for commercial crew services over the next three years, but a so-called compromise bill forged in the Senate slashed the proposal in half. After months of heated contention, the House of Representatives finally agreed to the Senate authorization bill in late September, calling for $1.6 billion for the commercial program.

Obama signs the NASA authorization bill

10:39 pm

Obama signed the NASA authorization bill today.

Update and bumped: This Spaceflight Now article includes this quote from Senator Bill Nelson (D-Florida):

“What is in this bill is $11.5 billion over the next six years, anticipated, even though it’s a three-year authorization, for development and testing of a heavy lift rocket. Now if we can’t develop a new rocket for $11.5 billion, building on a lot of the technologies that were already developed in spending $9 billion (on the Constellation program’s Ares rockets), if we can’t do it for that, then we ought to question whether or not we can build a rocket.”

Based on NASA’s track record in trying to build a replacement to the shuttle, I remain very skeptical indeed whether NASA can build this rocket. I do hope, however, that my skepticism is proven wrong.

Note also that the funding for this authorization bill is as yet not appropriated. Plans to do so during the lame duck session of Congress after the elections remain fraught with problems.
