Scientists have plans to go to killer asteroid

7:44 pm

Talk about thinking ahead! Since 2007 a team of scientists have actually been planning a mission to 1999 RQ36, the asteroid that has a 1 in 1000 chance of hitting the Earth in 2182. Their mission, dubbed OSIRIS-Rex (Origins Spectral Interpretation Resource Identification Security Regolith Explorer), has already been picked as one of two finalists in NASA’s New Frontiers program. The decision on which mission NASA will fund will be made next summer.

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 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.


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

Bat extinctions

2:01 pm

An article today in Science describes how scientists now believe that white nose syndrome is probably going to cause the extinction of the little brown myotis bat. Key quote from the press release:

The researchers determined that there is a 99 percent chance of regional extinction of little brown myotis within the next 20 years if mortality and spread of the disease continue unabated. They note that several other bat species may also face a similar risk.

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. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Leaving Earth cover

Leaving Earth: Space Stations, Rival Superpowers, and the Quest for Interplanetary Travel, can be purchased as an ebook everywhere for only $3.99 (before discount) at amazon, Barnes & Noble, all ebook vendors, or direct from my ebook publisher, ebookit.

Texas responds to EPA’s effort to regulate CO2

11:07 pm

In a letter response to the EPA’s effort to regulate carbon dioxide emissions, Texas has essentially told the EPA to go to hell. Three key quotes from the letter:

In order to deter challenges to your plan for centralized control of industrialized development through the issuance of permits for greenhouse gases, you have called upon each state to declare its allegiance to the Environmental Protection Agency’s recently enacated greenhouse gas regulations — regulations that are plainly contrary to United State law. ….. To encourage acquiesence with your unsupported findings you threaten to usurp state enforcment authority and to federalize the permitting program of any state that fails to pledge their fealty to the Environmental Protection Agency (EPA) [emphasis mine]

The State of Texas does not believe the EPA’s “suggested” approach comports with the rule of law.

Texas will not facilitate EPA’s apparent attempt to thwart these established procedures and ignore the law.

Melting Ice on Mars?

4:17 pm

These Mars Reconnaissance Orbiter images show in increasing magnification a puzzling feature in the southeast part of a ice mound in Louth Crater on Mars. Located at 70 degrees north latitude, this is the farthest south that scientists have found permanent water ice. The close-up image suggests melting ice with the draining water running down hill to the south, though on Mars the low air pressure would cause any liquid water to evaporate instantly. Key quote:

These may be the crests of partially defrosted dark sand dunes or perhaps some other feature that we do not understand. This is the only area on Louth where these enigmatic ridges are found.

Second test of Ares solid rocket scheduled

1:14 pm

Alliant Techsystems (ATK) has scheduled the second test of the five segment solid rocket motor, planned for use on the Ares I rocket, for August 31. Fun quote:

When fired, the motor will produce a maximum thrust 3.6 million pounds, or 22 million horsepower [half the power of the first stage of the Saturn V rocket]. The cases [segments] have all previously flown on the space shuttle, collectively launching on 57 missions.

The disconnect between Israelis and elites

12:56 pm

This long and fascinating interview about the Israeli-Arab conflict is quite eye-opening. Key quote:

Most Israelis are here because they fled from Muslim and European countries. They don’t feel that either of those blocs have the right to lecture them about anything. Why should a country where your parents were expelled or killed have the right to tell you how to conduct yourself in a war against people who are trying to kill you today? This is something hardly any non-Israelis understand. They don’t understand how galling we find this.

Israelis are often accused of being arrogant, but they find it extremely arrogant for Europeans and Arabs to lecture them about morals, especially during a war. What has Israel ever done that is as brutal as what Europe did to the Jews, or what Arabs routinely do to even each other during armed conflicts?

The great disconnect

12:25 pm

The recent history of NASA illustrates a fundamental problem with how our political class thinks.

In 2004 George Bush announced that NASA would have a new goal, that of the exploration of the solar system. The shuttle would complete construction of the International Space Station and then be retired in 2010. NASA would meanwhile build a replacement for the shuttle, designed to return to the Moon and beyond, and have it flying by 2014.

Notice the gap? The shuttle retires in 2010, four years before its replacement is available. Notice also that the plan insisted that ISS would be finished, fully occupied, and in need of significant resupply and maintenance during this entire time, when neither the shuttle or its replacement would be on hand.

Yet, as obvious as this seems, no one at NASA, in the Bush administration, or in Congress, seemed to notice this gap. The Bush plan was implemented exactly as described, so that today we are about to be left with a space station in orbit and no way to reach it for at least four years. (That other countries can reach the station changes nothing: the United States has been left hanging, lacking a method for transporting its crews to its own space station.)

It was as if, among the political and elite class that runs the government, there was great disconnect between the fantasy of the intended plan and the reality of its implementation. » Read more

A ground-based telescope matches the Hubble Space Telescope-NOT

6:01 am

Correction.Regular reader James Fincannon emailed me to say that he thinks the image below is an artist’s impression. He is correct. I should have looked more closely at the press release. In reading the actual research paper [pdf] on the results it seems that the VLT did some very sophisticated spectroscopy, thereby measuring the uneven distribution of the velocity and density of the gas around the star. The image below was then created, based largely on Hubble images combined with the new data. In other words, this ground-based telescope did not match the abilities of a space-based telescope in any way. Had the Hubble images not existed the astronomers would have struggled to interpret their spectroscopic data.

Some important astronomy news: The European Southern Observatory’s Very Large Telescope (VLT) has released this spectacular image of supernova 1987a, the first and so far only supernova visible to the naked eye since the invention of the telescope.

SN1987a

This image is important for two reasons. First, The data shows that the supernova explosion was not symmetrical, with more material being thrown outward in some directions than in others. This fact confirms what astronomers in recent years have increasingly come to believe: Supernovae explosions are not simple spherical bursts, but chaotic events ripping stars apart in a lopsided manner.

Second, this image demonstrates that ground-based telescopes are becoming amazingly good at doing what the Hubble Space Telescope has done routinely for the past two decades. Five years ago, no telescope on the ground could have resolved the inner ring of supernova 1987a. Only Hubble in space had that capability. Now, VLT can do it, almost as well as Hubble. Though a space-based telescope can still beat any ground-based telescope, it is great news that the technology for ground-based telescopes has improved so much, especially since there presently are no plans to replace Hubble.

Tunnel and tombs in Mexico

1:11 am

Archeologists have uncovered a previously unknown tunnel and several chambers under the Temple of Quetzacoatl north of Mexico City. Key quote:

Experts say a tomb discovery would be significant because the social structure of Teotihuacan remains a mystery after nearly 100 years of archaeological exploration at the site, which is best known for the towering Pyramids of the Moon and the Sun. No depiction of a ruler, or the tomb of a monarch, has ever been found, setting the metropolis apart from other pre-Hispanic cultures that deified their rulers.
