On August 9, 2010 the camera on Lunar Reconnaissance Orbiter took some routine calibration images and captured the Earth from lunar orbit, showing the western hemisphere with relatively little cloud cover. The picture below is a tiny piece from that global image, cropped to show the United States. The details are pretty remarkable, considering the distance. You can explore the full global image in detail here.

Research results posted today [pdf] at the European Planetary Science Congress show that the methane in Mars’s atmosphere is seasonally variable and far more short-lived than predicted, disappearing in less than a year. Some process, therefore, must be both using it and replenishing it. On Earth, that’s almost always done by some form of life process. Key quote by one of the scientists, from the press release:
“Only small amounts of methane are present in the martian atmosphere, coming from very localised sources. We’ve looked at changes in concentrations of the gas and found that there are seasonal and also annual variations. The source of the methane could be geological activity or it could be biological we can’t tell at this point.”
The image below shows the three regions (in yellow) where the methane is concentrated.
Though NASA’s Inspector General has cleared [pdf] NASA administrator Charles Bolden of ethical violations in connection with his communications with the Marathon Oil corporation during discussions about awarding research money to a Marathon competitor, the IG also noted that Bolden’s actions were inappropriate. Key quote:
We concluded that Bolden’s contact with Marathon regarding OMEGA did not violate federal laws or regulations pertaining to conflicts of interest. However, we found that the contact was not consistent with the Ethics Pledge he, as an Administration appointee, had signed, and that it raised concerns about an appearance of a conflict of interest involving the NASA Administrator and a large oil company to which he had financial ties.
Keith Cowing and Frank Sietzen at SpaceRef report that NASA administrator Charles Bolden will soon be heading to Saudia Arabia, ostentively to continue NASA outreach to the Muslim world, with other less obvious motives pertaining to Israeli/Palestine peace negotiations. Key quote:
According to one of several sources knowledgeable on the subject “expect to see a wave of mid-level Administration appointees embarking on a round of carrot-and-stick sweetener overtures” to Saudi officials to entice them to join the Obama effort. For their part, the Saudi government wants the U.S. to exert greater pressure on Israel to stop construction of settlements in occupied territories that might someday be a key in a peace accord. In the meantime the Obama administration is trying to give the Saudis every incentive to craft a stronger relationship with the U.S.
An evening pause: Here’s another Rube Goldberg machine, this time created for a music video from the band OK Go.
Despite the program’s budget uncertainties, testing by NASA of the Orion capsule continues.
On Friday I drove up to Westfield, New Jersey, to give a public lecture to Amateur Astronomers, Inc. at Union County College in Cranford, New Jersey. On this, my second visit to this amateur astronomy club, my lecture topic was the story behind the Apollo 8 mission to the Moon, the subject of my first book, Genesis: the Story of Apollo 8.
I visit a lot of astronomy clubs, giving talks on space and its history, so it is not a light complement when I say that this particular club is one of the most active, organized, and enthusiastic astronomy clubs I have ever seen. This is not to say that other clubs are not active, organized, or enthusiastic, only that it seems to me that the members of Amateur Astronomers are particularly so.
This fact only makes the decision by Union County College to throw the club and its observatory off campus seem incredibly stupid. Fortunately, the club has managed to negotiate a two year postponement of their eviction. What will happen after that, however, remains unknown.
The Washington Post today includes an excellent article outlining quite succinctly the mess that’s resulted from the space war between the House, the Senate, and the administration over NASA’s manned program. Key quote:
In an effort to restore a NASA consensus and fund future human space travel, negotiators from the House and Senate have been meeting frequently in recent weeks. Participants say, however, that the sides are dug in and that stalemate is a real possibility.
As I have been saying for months, don’t expect anything good to come from Congress, even if they come up with a compromise. Obama and NASA under Bolden did a very bad job selling their ideas to Congress, and Congress returned the favor by rejecting those ideas and instead coming up with two different plans, both of which serve their own parochial interests rather than the nation’s. The result is a micromanaged mishmosh that won’t get anything done, while wasting huges sums of cash that the federal government does not have.

For the fifth time in two years Mars Reconnaissance Orbiter has gone into safe mode because of a computer reboot.
Here’s a good inside look, with pictures, at the preparations for the October 23 launch of the second Falcon 9 rocket.
An evening pause: As today is the day in which our Founding Fathers ratified the Constitution, I thought it might be worthwhile to allow Andrew Klavan the opportunity to give us his “A Young Person’s Guide to the United States Constitution.” To quote: We are going to have a little civics lesson, to make up for what you’ve been learning in school.
Microbes survive 553 days attached to the outside of the International Space Station as part of a scientific experiment.
Rather than address the many questions people have about climate research (questionable research, unclear data, corrupt scientists), the White House has come up with a much better approach: Change the name of “global warming” to “global climate disruption.” Now, doesn’t that explain everything?
An evening pause: Though this sequence of shots from a 1922 Kodak test of Kodachrome film (possibly the earliest in existence) is hardly the stuff of drama, it is fascinating nonetheless, as it gives as an honest glimpse into the culture of its time. As you watch the different women pose for the camera, ask yourself: Has anything changed?

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.
