The second Falcon 9 rocket passes fuel test in anticipation of an October 23 launch.
New results from Lunar Reconnaissance Orbiter, including a new global topographic map.
From the caption: A lunar topographic map showing the Moon from the vantage point of the eastern limb. On the left side of the Moon seen in this view is part of the familiar part of the Moon observed from Earth (the eastern part of the nearside). In the middle left-most part of the globe is Mare Tranquillitatis (light blue) the site of the Apollo 11 landing, and above this an oval-appearing region (Mare Serenitatis; dark blue) the site of the Apollo 17 landing. Most of the dark blue areas are lunar maria, low lying regions composed of volcanic lava flows that formed after the heavily cratered lunar highlands (and are thus much less cratered).
The space war continues. Here is another article outlining the political state of war between the House, Senate, and administration over NASA’s future. Don’t expect anything good to come out of these political shenigans.
It appears that the Arctic icecap has reached its 2010 minimum. Though the icecap extent in the spring was the largest since 2002 (see image below), the melt was fast and the minimum appears to be the third lowest since 1979.
Does this mean the icecap is melting and will disappear shortly, as some politicians like to believe? Hardly. Though the data suggests a long term decline in ice extent, recent trends also show evidence that the icecap might be recovering. What will actually happen is still anyone’s guess.
Europe to the Moon! The U.S. may no longer have a coherent lunar exploration program, but Europe sees that water at the Moon’s south pole and wants it, awarding contracts today to begin the work of getting a lunar lander there.
Lost freedom, compounded! The artist who had first proposed the idea of “Everybody Draw Mohammad Day”, then backed off out of fear of attack, has now been forced to abandon her life and career and go into hiding.
It is just this kind of event that makes me wonder: Why would anyone consider Islam a “religion of peace?”
The U.S. is doing its own satellite maneuvers, placing for the first time a spacecraft into the Earth-Moon L1 and L2 points.
China is continuing the mysterious maneuvers of the two satellites that might have actually touched earlier this month. Key quote:
The maneuvers, which appear to involve rendezvous operations between the SJ-06F satellite and the more recently launched SJ-12 craft, could amount to practice for space station dockings or coordinated satellite observations from orbit. Few folks would have a problem with that. But they also could be aimed at developing the expertise for lurking near someone else’s satellte and eavesdropping, or even knocking that satellite out of commission in the event of a crisis. That’s the worrisome part.
A judge has overruled Andover Township in Ohio over its effort to squelch a Constitution Day rally by a Tea Party group, allowing the rally to go forward. Key quote:
“It’s very ironic that an effort to celebrate the Constitution results in a violation of the Constitution,” attorney Curt Hartman, part of the legal team representing the group, noted.
An evening pause: Though appearing somewhat hokey today, the original Star Trek is still one of the most intelligent television show ever produced, with decent writing that often expressed profound ideas. And it was about space exploration and the future! The clip below, from the episode Mirror, Mirror, illustrates all these things perfectly. And Kirk’s speech to the Spock from the alternative-universe expresses beautifully the significance of each individual’s responsibility to the world.
“One man cannot summon the future,” says the bearded Spock.
“But one man can change the present,” responds Kirk.
Freedom of speech alert! Ohio town forbids celebration of U.S. constitution in town square because of the “political affiliation” of the event’s organizers. Key quote:
Several residents of the small central Ohio town formed the Andover Tea Party in May 2010, and in that same month, they asked to use the square for a rally to commemorate Constitution Day, which celebrates the anniversary of the signing of the U.S. Constitution on September 17, 1787. But on July 19, a trustee informed one of the tea party organizers, Margaret Slingluff, that they would not be allowed to hold the event, which would have included singers performing patriotic songs and public policy-related speakers, in the square.
A court suit has already been filed.
Bumped, with update below
This Christian Science Monitor article gives a nice summary of the present state of war between the President, the House, and the Senate over NASA’s future.
All in all, things do not look good. With so much disagreement, whatever Congress and the President eventually agree to is going to be a mess, accomplishing little while spending gobs of money that the federal government simply no longer has. The result will almost certainly be a failed NASA program, an inability of the United States government to get astronauts into orbit, and an enormous waste of resources.
The one shining light in all this is that we still have a unrelenting need to get into space, not merely to supply the International Space Station but to also compete with other nations. It is my belief that this need — and the potential profits to be made from it — is going to compel private companies to build their own rockets and capsules for getting humans and cargo into space. And I think they will do it whether or not the federal government can get its act together.
Thus, though the U.S. might find itself a bystander in the space race for the next decade or so, in the end we will have a vibrant, competing aerospace industry, capable of dominating the exploration of the solar system for generations to come.
So buck up, space cadets. The near term future might be grim, but the long term possibilities remain endless.
Update: This announcement today from Boeing and Space Adventures illustrates my above point perfectly. For decades Boeing has been a lazy company, living off the government dole while doing little to capture market share in the competitive market. Now that the dole of government is possibly going away, however, the company at last appears to be coming alive. Instead of waiting for a deal with NASA, Boeing has been going ahead with its CST-100 manned capsule, figuring it can make money anyway by selling this product to both private and government customers.
There really is a light at the end of the tunnel: The 33 trapped miners might still be trapped, but all told they have so far received more than one thousand job offers.
How blind cave fish find food. Key quote:
“Vibration Attraction Behavior” (or VAB) is the ability of fish to swim toward the source of a water disturbance in darkness. Postdoctoral associate Masato Yoshizawa measured this behavioral response in both wild caught and laboratory raised cave and surface-dwelling fish using a vibrating rod at different frequencies as a stimulus. Most cavefish displayed VAB and would swim toward the vibrating rod and poke at it, while few surface fish did.
University of Arizona scientists have built a hydroponic lunar vegetable garden on Earth. More information here. Key quote:
The membrane-covered module can be collapsed to a four-foot-wide disk for interplanetary travel. It contains water-cooled sodium vapor lamps and long envelopes that would be loaded with seeds, ready to sprout hydroponically.
In a preprint paper [pdf] posted on the astro-ph website tonight, scientists have increased the odds, by one order of magnitude, that the asteroid Apophis will hit the Earth on April 13, 2036. Fortunately, these new odds remain low, at 1 chance in 4.5 million.
Freedom of speech alert: NJ Transit worker fired for burning pages of Koran.
NASA has now officially extended Boeing’s contract to operate the International Space Station through 2015.
Say goodbye to sunspots?
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.
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.”

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.
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.
