Killing private space
The financial foolishness in Congress, by Republicans this time, continues. In making its budget recommendations for NASA, the report [pdf] of the House Appropriations Commerce, Justice, Science, and Related Agencies subcommittee also demands that NASA immediately choose one commercial company for its commercial space program. (Hat tip to Clark Lindsey for spotting this.)
The number of ways this action is counter-productive almost can’t be counted.

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.

More problems for Dark Matter
A new study by astronomers has found a vast structure of satellite galaxies and star clusters aligned perpendicular to the Milky Way and extending outward above and below the galaxy’s nucleus by as much as a million light years.
In their effort to understand exactly what surrounds our Galaxy, the scientists used a range of sources from twentieth century photographic plates to images from the robotic telescope of the Sloan Deep Sky Survey. Using all these data they assembled a picture that includes bright ‘classical’ satellite galaxies, more recently detected fainter satellites and the younger globular clusters.
“Once we had completed our analysis, a new picture of our cosmic neighbourhood emerged”, says Pawlowski. The astronomers found that all the different objects are distributed in a plane at right angles to the galactic disk. The newly-discovered structure is huge, extending from as close as 33,000 light years to as far away as one million light years from the centre of the Galaxy.
An animation illustrating this galactic distribution is posted below the fold. You can read the actual preprint paper here.
The problem with this polar alignment with the Milky Way’s core is that the theories for explaining the distribution of dark matter do not predict it.

To mine the asteroids, first build small cheap space telescopes.
To mine the asteroids, first build small cheap space telescopes.
The space telescope will be based on the same design Planetary Resources will eventually use for its asteroid-prospecting spacecraft: a 30-kilogram to 50-kilogram flier packed with imaging sensors and a laser-optical communication system the company is developing to avoid encumbering its spacecraft with large antennas. The company, which says it has about two dozen employees, will market these spacecraft as cheap but effective telescopes for both astronomical and Earth-observing applications. Sales would provide cash for the company’s core work on asteroid mining, Eric Anderson, co-founder and co-chairman of Planetary Resources, said.
The telescope slated for launch sometime in the next two years “would be something, let’s say, a university buys [for astronomical observations], or a commercial company that wants to monitor shipping traffic or something like that,” Anderson said in a phone interview. The cost for the telescope, which Planetary Resources is calling Arkyd-101, would be “millions of dollars, including launch.”
At the Planetary Resources press conference today, there was a lot of talk about the benefits and profits to be gained from mining the asteroids. However, this ain’t gonna happen for quite a few years. In the meantime, the company plans to make money building space telescopes which scientists and others can use, for a fee, to do research.
In other words, the government and astronomers dropped the ball on replacing the Hubble Space Telescope. Now, private enterprise is going to pick it up and run with it.

The video at the link is quite interesting to watch. Note however that the press information says nothing about whether the icecap was larger or smaller than expected, something that probably is not surprising. It will probably take decades of further work to get the true context of these results.

“The problem is we don’t know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books – mine included – because it looked clear-cut, but it hasn’t happened,” Lovelock said. “The climate is doing its usual tricks. There’s nothing much really happening yet. We were supposed to be halfway toward a frying world now,” he said.
“The world has not warmed up very much since the millennium. Twelve years is a reasonable time… it (the temperature) has stayed almost constant, whereas it should have been rising — carbon dioxide is rising, no question about that,” he added.
