Does Mars’ atmosphere contain methane, and if so does this suggest life on Mars? The scientists debate the question.
An evening pause: From the Abbott and Costello film Buck Privates (1941).
To me, the word that best describes this is exuberance. Faced with war and threatened with destruction, the American nation responded with defiant humor.
A House subcommittee has proposed trimming the budget of the FAA’s commercial space office from the $15.2 million it received in 2010 and 2011 to $13 million for 2012.
This is good, to my mind. Cutting their budget will pull the teeth from their regulatory efforts. As the commercial space industry ramps up, the political pressure on this office to approve permits will increase, and if they are short of cash they will have no choice but to keep things simple and say yes.
Update: Thanks to Joe2 for noting my error: the budget numbers above have been corrected to millions, not billions.
NASA thinks it will cost $18 billion to complete and launch in 2017 one test flight of the Congressionally-designed Space Launch System, the program-formerly-called-Constellation.
This is madness. One flight, unmanned, in seven years? No sane customer would ever buy such a product, especially when there are now a number of cheaper competitors who will likely be flying manned in less time.
Note also that even if NASA’s figures are exaggerated, which I am sure some Senators and Congressmen will claim, I would bet that they are not that far off, based on the space agency’s fixed labor costs and past history.
The twin GRAIL gravity probes launched successfully on Saturday and are now on their way to the moon.
Updated and bumped: I wrote the following last year on September 11. Sadly, nothing has changed since then. President Obama is still trying to sell the idea that this day should be used as a day of service, something that misses the point so completely as to almost be despicable.
So, I think it is worth repeating what I wrote on September 11, 2010:
The President has asked us to consider today “a national day of service and remembrance”. Though the sentiment seems reasonable, I must respectively disagree.
September 11 should not be turned into a day to celebrate volunteerism or service or American charity. Though these values are profound, important, and an expression of much of what makes our nation great, they are not why we remember September 11.
We remember the evil acts commited on September 11, 2001 in order to remind us that there is evil in the world.
We remember these evil acts so that we will have the strength to fight that evil, with every fiber of our being.
We remember those who died in order to prevent future attacks and further deaths.
We remember so that no one can ever try to make believe these events did not happen.
We remember so that no one can spread the lie that the perpetrators were something other than what they were: Men who had decided to kill in the name of Islam, based on what they believed their religion taught them.
And finally, and most important, we remember the horrible events of September 11, 2001 so that those innocent murdered souls — whose only crime that day was going to work — will not have died in vain.
This is not good if true: SpaceX has admitted that in its December 2010 test flight of Falcon 9 there was a problem with its first stage.
During the August meeting, held at the Johnson Space Center in Houston, SpaceX told to the two advisory bodies that there had been an engine anomaly during the most recent Falcon 9 launch, according Charles Daniel, a shuttle and space station safety expert at Herndon, Va.-based Valador Inc., and a member of the ISS Advisory Committee. “There was no explanation or root cause analysis or corrective action for this particular anomaly,” Daniel said Sept. 9 during the public meeting. “This is a relatively troublesome statement not to recognize that a premature engine shutdown was a significant event.”
ATK and NASA to announce a new commercial space agreement on Tuesday.
This is almost certainly in connection to the successful third test firing of ATK’s solid rocket yesterday.
The Senate has approved a flat budget for the Department of Energy.
On Wednesday the Senate Appropriations Committee approved $4.843 billion for DOE’s Office of Science in 2012. That’s the same level as this year, and a slight bump over the $4.8 billion approved in July on a largely partisan vote by the House of Representatives covering the entire department. Although the funding is a far cry from the $5.416 billion that the Obama Administration had requested in February for the next fiscal year, which begins on 1 October, officials at the Office of Science’s 10 national labs say they’re not complaining. “Even staying flat when a lot of other programs are getting cut is relatively good news,” says Thom Mason, director of Oak Ridge National Laboratory in Tennessee. In budgets, “flat is the new good,” quips Eric Isaacs, director of Argonne National Laboratory in Illinois. [emphasis mine]
That a government official is now happy that the budget is flat is a good sign that we might finally be making some cultural progress in terms of bringing the federal budget under some control. In the past the very thought of no increase would have sent these people into spasms of outrage. Now they realize how pointless such a tantrum would be, and might actually do their budget negotiations harm.
Doesn’t this make you feel safer? TSA is now digging into personal medical records to deny Canadians entrance to the United States.
Oh my! Another poll shows the Republican leading in the New York special congressional election, now by an increased margin.
Also, the Democrat candidate admits he doesn’t even live in the district.
NASA’s Fermi Gamma-Ray Telescope today released an updated catalog of the last two years of its survey of the sky at high energy emissions. All told, there are 1873 objects in the catalog, more than half of which are supermassive black holes at the center of distant galaxies. You can see this all-sky map below the fold.
Many of the objects are quite familiar, such as the Crab Nebula, the remnant of a supernova that exploded a little less than a thousand years ago.
For decades, most astronomers regarded the Crab Nebula as the steadiest beacon at X-ray energies. But data from several orbiting instruments — including Fermi’s Gamma-ray Burst Monitor — now show unexpected variations. Astronomers have shown that since 2008, the nebula has faded by 7 percent at high energies, a reduction likely tied to the environment around its central neutron star.
Since 2007, Fermi and the Italian Space Agency’s AGILE satellite have detected several short-lived gamma-ray flares at energies hundreds of times higher than the nebula’s observed X-ray variations. In April, the satellites detected two of the most powerful yet recorded. To account for these “superflares,” scientists say that electrons near the pulsar must be accelerated to energies a thousand trillion times greater than that of visible light — and far beyond what can be achieved by the Large Hadron Collider near Geneva, Switzerland, now the most powerful particle accelerator on Earth.
What I, and many astronomers, find even most interesting about this catalog, however, is the large number of completely mysterious objects scattered across the sky, objects that emit powerful gamma rays but are not visible in any other wavelengths. All told, these unidentified objects comprise almost one third of the entire catalog.

Madness: The EPA is using taxpayer money to encourage environmentalist groups to sue the EPA.
Hmm: Newly released data links a Saudi family, now living safely in Saudi Arabia, with the 9/11 hijackers.
The space war heats up: Two senators have issued a statement lambasting the Obama Administration for its budget numbers for building the program-formerly-called-Constellation.
All of this is fantasy and foolishness. These senators might succeed in forcing NASA to spend money on the heavy-lift rocket that Congress has mandated, but there is no way the space agency will ever get enough funding or time to finish it. Even if the lower estimates are right, the cost is exorbitant, many times that of what the private companies have spent for their rockets and ships. And if construction does begin in earnest, it cannot be finished before the arrival of a new President in 2016 (at the latest), who, like all new Presidents, will have his own plans and will not want to build something started by the previous administration.
Much better to end this farce and save the money, especially considering the debt of federal government.
GRAIL launch delayed again until Saturday.
More Progress freighter crash investigation results: it appears there was something that blocked the fuel supply.
“The exposed production defect was accidental,” [the investigation] said, adding the reason may be qualified as an isolated case only after checking all available engines.
This suggests that the problem was an isolated error and that, once they have cleared the available engines, they can start flying relatively quickly.
ATK today successfully test fired the five segment solid rocket originally intended for the Ares 1 rocket. More here.
This solid rocket motor has value, but ATK’s hope that NASA will use it as part of the Congressionally designed Space Launch System, what I call the program-formerly-called-Constellation, is probably a false hope. They might get a few years of funding from Congress, but the whole thing will die stillborn when the funding runs out.
Better that they packaged the motor as part of a private launch system and tried to get some commercial business with it.
Regardless, the video is fun to watch. Check it out.
Today’s launch of the lunar gravity probe GRAIL has been scrubbed due to high winds and rescheduled for tomorrow.
Japan has successfully completed a two second test fire of the engine on its lost Venus probe Akatsuki.
A defunct seven-ton NASA climate satellite is about to fall to Earth.
The Upper Atmosphere Research Satellite, or UARS, is expected to come down in late September or early October, the space agency said today in an advisory. “Although the spacecraft will break into pieces during re-entry, not all of it will burn up in the atmosphere,” NASA said.
Virgin Galactic announced today that it will co-host an industry day at Spaceport America in New Mexico on October 18 in order to locate suppliers for its space tourism business.
“This is a fantastic opportunity for companies ranging from local New Mexico firms to national corporations to understand our unique needs for goods and services, including our requirements in building and servicing multiple commercial spaceships as the market further develops,” said Virgin Galactic’s President and CEO George Whitesides. “Our intention is to establish these relationships and emphasize our desire to hire locally as much as possible.”
A Dutch university has fired a noted social psychologist who has admitted his science research was based on faked data.
[Diederik] Stapel has worked at the university, located in southern Netherlands, since 2006. He is known as a prolific researcher and a successful fundraiser. His studies appeared to offer new insights into the workings of the human mind; for instance, a Science paper published in April showed that people are more likely to stereotype or discriminate in messy environments.
In the TV interview, [university rector Philip] Eijlander says he was first contacted on 27 August by “junior researchers” in Stapel’s lab who alleged that his conduct was fraudulent. Stapel immediately admitted that there was “something strange” in his papers, Eijlander says, and “yesterday, he told me that there are faked data.” The university has asked Willem Levelt, a psycholinguist and former president of the Royal Netherlands Academy of Arts and Sciences, to lead a panel investigating the extent of the alleged fraud. Eijlander says that all “tainted papers” will be retracted. [emphasis mine]
I purposely emphasis the publication of this faked research in the peer review journal Science to illustrate how this story once again demonstrates that just because a science paper is peer reviewed, that is absolutely no guarantee that it is either correct, or even legitimate. The field of science (with a small “s”) always requires everyone to exercise a strong sense of skepticism. Appeals to authority (“It was published in Science!”) should carry no weight.
The nearest supernova in almost a quarter century is now visible using binoculars.
The Left has fought the spread of genetically modified (GM) foods with every weapon in its arsenal. Leftists did this in the name of combating a long list of “potential risks” that never materialized. They have been permitted to overlook the fact that their assaults on GM food were not cost free. For instance, they have greatly delayed and in some places stopped cold the use of rice modified to increase vitamin A content. For the Left this is cause for celebration. In fact, widespread use of this “golden rice” would have prevented a half-million cases of child blindness a year. So the next time someone talks to you about the evils of genetically modified foods, remind him of the millions of poor children this crusade has condemned to a lifetime of blindness. How do folks prepared to allow millions to needlessly go blind still command the respect of any truly moral person?
And that’s only the start. Read the whole thing.
