Knife’s Edge trail on Mount Katahdin
An evening pause: How about some more hiking on the edge of the world? This is the Knife’s Edge trail on Mount Katahdin, Baxter State Park, Maine.
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

The federal government’s very expensive and probably unnecessary project to build a high speed railroad line between two cities in Wisconsin — using stimulus money — is having a significant influence on the elections there. Key quote:
With the U.S. economy in shambles and our national debt strangling the country, it doesn’t bode well for Feingold that he supported the wildly unpopular health-care bill, which [challenger] Johnson wants repealed, as well as last year’s big clunker, the stimulus bill. Feingold’s support for the unfunded and bottomless money pit of [high speed rail] doesn’t appear to be working for him either. If an entrenched insider like Feingold loses, it could have serious ramifications for the future of high-speed rail across the country. [emphasis mine]

Science discovers the obvious! The US Geological Survey has learned that if water looks and smells bad, you probably shouldn’t drink it.
The harsh environment of space, normally hostile to most materials, acts beneficially to cure certain epoxy resins. Key quote:
“You don’t have to take it up there in the shape that you eventually want,” said University of Sydney physicist Marcela Bilek, a co-author of the new study. “You can take something in a packaged form, all folded up, and then inflate it in space and have it cure into a mechanically solid structure.”

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.
“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.

Good news for science: UCLA has backed off from its plan to fire a politically incorrect professor, giving Dr. James Enstrom an eight month reprieve as it reviews his case.
Don’t bet the bank on this: In a preprint paper posted tonight on the astro-ph website, scientists predict the discovery of the first Earthlike extrasolar planet — using statistical analysis alone! Fun quote:
Using a bootstrap analysis of currently discovered exoplanets, we predict the discovery of the first Earth-like planet to be announced in the first half of 2011, with the likeliest date being early May 2011.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke
Back to the climate-theory drawing board: A paper published today in Nature Geoscience suggests that the ocean conveyor belt that brings warm water to the northern Atlantic is far more complex than the original theories proposed. These results strengthen earlier reports that also questioned the conveyor belt theory.
The number one injury reported by astronauts appears to be fingernail and hand injuries resulting from the use of spacesuit gloves. Key quote:
A previous study of astronaut injuries sustained during spacewalks had found that about 47 percent of 352 reported symptoms between 2002 and 2004 were hand related. More than half of these hand injuries were due to fingertips and nails making contact with the hard “thimbles” inside the glove fingertips. In several cases, sustained pressure on the fingertips during EVAs caused intense pain and led to the astronauts’ nails detaching from their nailbeds, a condition called fingernail delamination.
Using archival Hubble Space Telescope images astronomers have discovered 14 objects orbiting the Sun beyond Neptune. Key quote:
The newfound objects range from 25 to 60 miles across (40 to 100 kilometers), said the researchers.
This breath-taking image of Saturn and its rings was taken by Cassini on July 19, 2009 and posted on the Cassini image gallery on August 27, 2010.
All systems go! The project engineer of the Dawn mission has posted a very detailed update (as of August 30), describing the spacecraft’s status in its journey to the asteroid Vesta.
Good news for private space! Scaled Composites put WhiteKnightTwo back in the air today, only three weeks after one of its landing gears failed during a landing. You can read the test flight logs here.
Engineers are reviewing the life expectancy of the International Space Station, in light of the desire of politicians to keep it operating through the 2020s. Intriguing quote:
Airlines and airplane contractors commonly inspect aircraft for such fractures, but with the space station out of reach more than 200 miles up, engineers rely on complex models to predict their growth in orbit.
The space war over NASA continues. The Orlando Sentinel has an article today selling the merits of the Team Direct concept that would use most of the shuttle hardware to replace it.
An evening pause: The Westerner (1940). Gary Cooper is wonderful, but it is Walter Brennan as Judge Roy Bean who steals the show.
Paul Spudis at Air and Space magazine has some more thoughts about the origins of that natural bridge on the Moon that Lunar Reconnaissance Orbiter photographed recently.
An evening pause:. September 11, 2001. Nine years ago. We mustn’t forget. Such evil must be faced, and defeated.
The Sun is spotless again. By this stage in the ramp up to solar maximum, such things should no longer be happening.
There is a lobbying push among a lot of space activists to get the House NASA authorization bill changed so that more money is spent for commercial space. Unfortunately for these activists, reality is about to strike (almost certainly on November 2). Also see this story: Our debt is more than all the money in the world.
With a new Congress almost certainly dominated by individuals who want to shrink the size of government, I doubt anyone in the space industry is going to get much of what they want in the coming years.
More data from Kepler! In a paper [pdf] published today on the astro-ph website, scientists outline Kepler’s census of the variability of stars. Key quote from the abstract:
We have separated the sample in 129,000 dwarfs and 17,000 giants, and further sub-divided, the luminosity classes into temperature bins corresponding approximately to the spectral classes A, F, G, K, and M. G-dwarfs are found to be the most stable with < 20% being variable. The variability fraction increases to 30% for the K dwarfs, 40% for the M and F dwarfs, and 70% for the A-dwarfs. At the precision of Kepler, > 95% of K and G giants are variable.
The detection in June by two different amateur astronomers of an impact on Jupiter bodes well for asteroid/comet research. You can read the actual paper here. [pdf] Key quote from the abstract:
A systematic study of the impact rate and size of these bolides can enable an empirical determination of the flux of meteoroids in Jupiter with implications for the populations of small bodies in the outer Solar System and may allow a better quantification of the threat of impacting bodies to Earth. The serendipitous recording of this optical flash opens a new window in the observation of Jupiter with small telescopes.
Updated and bumped: John’s obituary can now be read here.
John Wilcox, the man most responsible for finding the connection between Kentucky’s Mammoth Cave and the Flint Ridge Cave system and thereby producing the world’s longest cave system, died today after a three week long illness. To quote Roger Brucker, co-author of The Longest Cave, Wilcox “was known for his systematic approach to exploration and laser-like focus on detailed mapping.” R.I.P.
Boeing, which is now building its own private space capsule, and Space Adventures, the company that flies tourists to space, are apparently teaming up. More details will be announced at a press conference is scheduled for next week.
The mapping of the atmospheres and surfaces of some extrasolar planets, even at distances of many light years, is now possible.
Set to launch before year’s end, construction of China’s next lunar probe, Chang’e 2, appears to be on schedule, at least according to Chinese news sources.
Two stories from the so-called “city of brotherly love”:
First, a woman whose son was murdered decided she needed to protect herself. She legally obtained a concealed carry permit and purchased a gun, only to have the police come to her home, arrest her, and confiscate it. Key quote:
“I thought they were coming to my door to tell me they had my son’s murderer,” [the woman] said. “But they were coming to take me and my gun, and now I’m defenseless.”
In the second story, it appears that Philadelphia police are making a policy to arrest security guards and confiscate their guns, even though the guns were lawfully obtained and legally permitted. At least nine different security guards have experienced this form of Philadelphia thuggery. Key quote from Lieutenant Fran Healy, special adviser to the police commissioner:
“Officers’ safety comes first, and not infringing on people’s rights comes second.”
By the way, Philadelphia is the same city that now wants to charge a $300 business license for anyone writing a blog, regardless of whether they are running a business or hobby, and thus effectively stifling free speech.
An evening pause: From Stephen Sondheim’s Pacific Overture, the song “Someone in a Tree,” from the 1976 Broadway production.
It’s the fragment, not the day
It’s the pebble, not the stream
It’s the ripple, not the sea
That is happening.
Not the building but the beam
Not the garden but the stone
Only cups of tea
And history
And someone in a tree.
