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.

Law of unintended consequences strikes again. The new healthcare law has a provision, unrelated to healthcare, that involves a paperwork nightmare for small businesses.
A political note: my Congressman happens to be Steny Hoyer, who waxed poetic recently about taxes and the coming expiration of the Bush tax cuts. Hopefully, this man will free Hoyer from such concerns.

"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
The space war over NASA continues. The pushback from commercial space advocates and industry proponents seems to be having an effect. House aides have indicated that the House NASA authorization bill will not be voted on until September.
The Japanese space agency JAXA has put Hayabusa’s heat shield, outer capsule, and parachute on public display, to large crowds.
An evening pause: Not only does Eddi Reader probably have one of the most beautiful voices in the singing world today, she links that voice to some of the best Irish instrumentalists in the game. Watch her and her band bring down the house in this live performance of “Willie Stewart”.
The space war continues. Jeff Foust has two reports today on the political state of NASA’s budget. First, Congress has approved language that requires continuing funding of Constellation. Second, it looks like the House may vote on the new NASA authorization bill this week.
Glenn Reynolds of Instapundit today said the following (in recognizing Jeff Foust’s op-ed for Technology Review):
CONGRESS BLOWS IT: Commercial Spaceflight, We Have A Problem. Congress will always choose short-term pork over long-term development unless there’s strong Presidential leadership. But while the Obama space policy is good, the White House hasn’t provided the kind of legislative push it takes to make it work. Without strong leadership, a good policy will always lose out to pork.
Didn’t someone say this already? In fact, didn’t that someone say this more than once?
An evening pause: Yesterday we had a modern animation of a machine that made music. Tonight let’s watch a very different take on a vaguely similar idea, this time to produce comedy. This is a classic skit from Your Show of Shows, Sid Caesar’s variety show from early television. The four performers are, left to right, Sid Caesar, Imogene Coco, Carl Reiner, Howard Morris.
Two NASA probes, originally launched to study the Sun and having completed their mission, have had their orbits adjusted so that they can study the Moon instead.
Radar images from Lunar Reconnaissance Orbiter appear to show deposits of approximately 1.6 trillion pounds of water ice on the Moon.
The United Space Alliance, which runs shuttle operations for NASA at Cape Canaveral, has announced layoffs roughly 900 effective October 1. Key quote: “Local workforce officials expect that up to 8,000 KSC employees could lose jobs by the time the shuttle program ends.”
The space war continues. Congressman Frank Wolf (R-Va) of the House Appropriations committee says that there is little chance the NASA budget will be approved until January.
An evening pause: Though it might look real, the music machine in this short is animated, a creation of Animusic, a company dedicated to producing animated shorts set to music.
Solar sail engineers from around the world gathered in Brooklyn last week for the Second International Symposium on Solar Sailing. Ben Diedrich, fellow caver, solar sail expert, and the man behind wiki.solarsails.info, gave two papers. He also emailed me to say that “Japan’s contingent gave several talks – many of which compared analysis of deployment, flight, or steering with actual flight data” of Ikaros. A review of the program [pdf] revealed some fascinating uses for solar sails. I like this paper title the best: “Deflecting Apophis with a flotilla of solar sails.” [ed. Apophis is an asteroid with the potential of hitting the Earth.]
Update: Japanese scientists have now announced that they have been able to adjust Ikaros’s attitude using sunlight.
Another update: Ben Diedrich emailed me the link to read the actual proceedings from the conference. See pg 103 to read the paper on using solar sails to deflect Apophis.
An experiment flown in space for 10 days by the European Space Agency has found that three species of lichen can survive the hazards of outer space.
End of the world alert! Scientists have identified an almost half mile wide asteroid with a 1 in 1000 chance of hitting the Earth in 2182.
During a spacewalk at ISS yesterday, two Russian cosmonauts successfully replaced a broken camera and installed new wiring for the recently added Russian Dawn module. They also lost a washer and an “attachment fixture” used to fasten the wiring in place, both of which were spotted floating away.
The General Accountability Office has ruled that the Obama administration’s decision to require contractors to reserve money for the possible termination of the contract, thereby forcing them to cut back early on the Constellation program, was legal.
An evening pause: Here’s some modern music, Poker Face, performed not by its original singer, Lady GaGa, but by Molly Lewis, someone far more appealing.
A cave exacavation in East Timor has uncovered the bones of the largest rat species on record, weighing over 13 pounds and living approximately one to two thousand years ago. The dig also uncovered 11 previously unknown rat species.
James Fincannon of NASA took the two images of the Marius Hills lunar pit taken at different times by Lunar Reconnaissance Orbiter (which I posted here) and did an overlay so that the shadow produced by pit’s rim could be easily compared with the rim itself (see below). He then did some calculations based on the sun’s angle of light shining into the cave and came up with the following calculations:
I estimate it is 60 meters from rim to bottom. The floor is flat below the surface. The rocks on the flat surface below ground are in stark relief (hard shadows) compared to above ground due to the sun coming only at one angle while above ground the albedo/reflections makes for soft shadows at this high sun angle (65 deg elevation). I cannot tell if the black portion of the combo image is a slope or more flat floor. Need a different high sun angle or azimuth to fill that in. Still I like the general pattern of the rim matching the shadow on the floor, although the image I found originally has that edge of the cave rim in shadow for a large extent.
A 60 meter drop is about 200 feet deep. This result is reasonably close to the depth estimated by Japanese scientists, 88 meters or 288 feet, based on images of the same lunar pit taken by their Kaguya probe.
Knowing the approximate depth of the entrance pit raises the much more important question: How will future lunar explorers to get to the bottom of this pit? It is ironic » Read more
In its first six weeks of observation, the Kepler mission apparently found almost 150 planets similar in size to the Earth. The results, learned by accident because a talk given by one of the co-investigators was posted on the web, have not yet been officially announced because the project scientists feel a need for additional time to confirm them. Many of these so-called planets might turn out to be false positives, so some caution is in order.
On Saturday (July 24) the American Geophysical Union published a paper in Geophysical Research Letters, entitled “Northern Hemisphere winter snow anomalies: ENSO, NAO and the winter of 2009/10.” This paper attempted to explain the unusually cold 2009-2010 winter, with its record snow falls.
The conclusions of the paper were reasonable, noting that this past winter experienced both an El Nino event in the Pacific as well as a very negative (cold) North Atlantic Oscillation (NAO). To quote the paper’s conclusions: “In winters when an El Nino event and a negative NAO combine, analysis reveal that there are positive snow anomalies across the southern U.S. and northern Europe.”
The authors of the paper made no attempt to explain why these two climate events “combined” this past winter, which in the field of climate change is actually the essential question. What caused it? Moreover, did the deep and extended negative (cold) phase of the Arctic Oscillation (AO) contribute as well, and if so, why did the AO also go negative this winter? And finally, were all these climate events somehow related to the Sun’s unusally long and deep solar minimum?
That they didn’t answer these fundamental questions is not surprising. Climotogists have been struggling with them for decades, and to expect this quickly written paper focused on this one climate event — the cold winter of 2009-2010 — to answer them would be unreasonable. In fact, considering the state of our knowledge, it probably is impossible for any paper to answer these questions at this time.
What makes this particular paper really noteworthy, however, is a quote in its introductory paragraphs:
The wintry winter has encouraged deniers of global warming » Read more
An evening pause: In our modern “politically correct” society, many people object strenuously when I express my unwavering preference for the British-American culture that founded the United States. It seems that today’s polite society considers it judgmental and unfair to suggest our way of life is superior to others. Well, before you protest, please listen to this speech from the movie Gettysburg, in which Colonial Joshua Chamberlain explains why he decided to fight for the Union in the Civil War. To quote, “We are here for something new. This has not happened much in the history of the world. We are an army out to set other men free.” Then he adds this most important point: “Here we judge you by what you do, not by who your father was.”
That is our culture. That is what we as a society have always stood for. And it is these values that I wish to propagate to the stars, a desire for which I will make no apologizes.
