Boeing is about to begin environmental tests on a new composite fuel tank for rockets.

12:52 pm

The competition heats up: Boeing is about to begin environmental tests on a new composite fuel tank for rockets.

Tanks made of composite materials have been a dream of space engineers for decades. Lockheed Martin tried to build them for the X-33, and their failure was essentially what killed that spacecraft. If Boeing is successful here and the composite tanks can then be put into a variety of launch rockets, the savings in weight will lower the cost of getting payloads to orbit significantly.

As the NASA lunar probe LADEE nears its planned end — where it will crash onto the Moon — the scientists running it admit that they have as yet been unable to solve its primary scientific question about levitating lunar dust.

As the NASA lunar probe LADEE nears its planned end — where it will crash onto the Moon — the scientists running it admit that they have as yet been unable to solve its primary scientific question about levitating lunar dust.

A major goal of the mission was to understand a bizarre glow on the Moon’s horizon, spotted by Apollo astronauts just before sunrise. “So far we haven’t come up with an explanation for that,” project scientist Rick Elphic, of NASA’s Ames Research Center in Moffett Field, California, said at a media briefing on 3 April. One leading idea is that the Sun’s ultraviolet rays cause lunar dust particles to become electrically charged. That dust then lofts upwards, forming a cloud that caught the light and the astronauts’ eyes.

LADEE carries an instrument that measures the impact of individual dust particles, as well as the collective signal from smaller particles. Lunar scientists had expected a certain amount of tiny dust to explain what the Apollo astronauts saw. But LADEE didn’t find it. “We did measure a signal that indicates that the amount of lofted dust has to be at least two orders of magnitude below the expectations that were based on the Apollo reports,” says Mihály Horányi, the instrument’s principal investigator, who is at the University of Colorado. Perhaps the dust lofting happens only occasionally, he suggests, and the astronauts were in just the right place at the right time to see it.

This remains an important question. Knowing what caused that horizon glow and knowing how often it occurs is essential knowledge for any future lunar base or research station.

Because of a $10 million shortfall in its astrophysics budget, NASA is weighing the fate of nine operating space telescopes.

10:00 pm

Because of a $10 million shortfall in its astrophysics budget, NASA is weighing the fate of nine operating space telescopes.

Six of the projects vying for extended funding are U.S.-based. Three are overseen by international space agencies and have U.S. partners.

The NASA missions are: the Fermi Gamma-ray Space Telescope; the Nuclear Spectroscopic Telescope Array X-ray observatory; the infrared Spitzer Space Telescope; the Swift Telescope, which tracks gamma-ray bursts; a proposed Kepler space telescope follow-on mission known as K2; and the Wide-field Infrared Survey Explorer, which was brought out of hibernation last year to help search for asteroids on a collision course with Earth.

Also in the running are two European Space Agency missions, XMM-Newton — an X-ray observatory — and Planck, which studied relic radiation from the Big Bang. Planck was decommissioned in October, but its data analysis program continues.

The final contender is Japan’s Suzaku X-ray telescope.

UrtheCast has released its first image of Earth, taken from one of its cameras on ISS.

UrtheCast has released its first image of Earth, taken from one of its cameras on ISS.

The UrtheCast (pronounced Earth-Cast) system, which was installed (not without trouble) on the International Space Station at the end of 2013, is composed of two cameras. The Theia “medium resolution” camera took this shot; the full picture has a resolution of 3200×8000, or about 25 megapixels. The high-resolution device, which will capture video, is still being calibrated.

Eventually UrtheCast plans to provide free, constant, near-real-time video of the globe from far above — that is, when it’s not being rented out to parties interested in a quick satellite snap of an area. Powerful cameras able to respond quickly to such requests are in high demand by everyone from law enforcement to disaster-relief coordinators.

A skydiver’s helmet cam captures a meteorite zipping past him as it falls.

2:11 pm

A skydiver’s helmet cam videotapes a meteorite zipping past him as it falls.

The incident happened back in the summer of 2012, when skydiver Anders Helstrup and other members of the Oslo Parachute Club took to the skies above Hedmark, Norway. Helstrup documented the jump with two cameras fixed to the front and back of his helmet. Helstrup tells NRK (the largest media outlet in Norway) that on the way down he felt “something” happen, but didn’t know what. It was only after landing and reviewing his camera footage that he discovered something shocking: a rock had fallen from the heavens and missed him by just a few yards.

Video below the fold. The news woman is annoying, but the footage is quite cool.

The terrible close-mindedness of the left.

The terrible close-mindedness of the left.

Watch the video below the fold. (The link above also transcribes much of the dialogue if you have trouble hearing it.) It is very disturbing. At the National Young Feminist Leadership Conference a female reporter merely wants to interview attendees, and she gets shunned for only one reason: They discover she is from a “conservative” organization.

The irony of this behavior is completely lost on the conference participants, which proclaimed its “inclusivity” and condemned any behavior that “makes folks feel uncomfortable, threatened, or demoralized.” Moreover, their behavior suggests they know deep down that their positions are indefensible, or else they would be glad to discuss them with their opponents.

Finally, this behavior is terrifying, as it suggests these individuals think their opponents are so evil that they will be willing to do almost anything to shut them up. With beliefs like this, from women being trained as future feminist leaders, the future for freedom in American does not bode well.

Watch how Chicago’s middle class has been destroyed by the radical leftwing Democratic Party during the past forty years.

10:00 am

Watch as a single graph illustrates how the policies of the radical leftwing Democratic Party during the past forty years has destroyed Chicago’s middle class.

Though the propaganda goal of this story is to push the Democratic Party’s new talking point of income equality, the graph does a better job of showing us the consequences of Democratic rule. Chicago has been run by Democrats forever, but only by radical leftwing Democrats since the 1970s, which is exactly when the middle class there started to flee.

A scientist whistleblower has found that publicly questioning bad science papers vs privately notifying the publisher significantly increases the chances of getting them retracted.

9:50 am

Surprise, surprise! A scientist whistleblower has found that publicly questioning bad science papers vs privately notifying the publisher significantly increases the chances of getting them retracted.

[Paul] Brookes ran the blog Science Fraud from July 2012 to January 2013, before closing it down in response to threats of legal action. For the PeerJ study, Brookes compared the outcomes of two sets of papers — 274 whose alleged data problems he chronicled on his blog, and 223 that he was e-mailed about but did not post before he shut the site down. Those private e-mails, he says, were also copied to the relevant journals, funding agencies and authors’ research institutions, so authorities would also have had the opportunity to review the allegations.

Of the 274 papers Brookes blogged about, 16 were retracted and 47 corrected by December 2013, he reports, meaning that action was taken in 23% of the cases. But of the 223 unpublicized papers, only two were retracted and five corrected — a rate of 3%.

As always, the more freedom and openness we have, the better. The only people who suffer in such a situation are the incompetent and dishonest ones.

Brian Binnie, the man who flew SpaceShipOne for Scaled Composites, has left that company for competitor XCOR.

It might simply be the man got a promotion, but it also might be that he knows the problems SpaceShipTwo is having and sees his chances of flying there going down. His willingness to work for XCOR instead could also be looked at as a kind of endorsement of that company’s chances of success.

NASA’s short statement, in connection to the Obama administration’s decision to suspend all non-ISS related activities with Russia, is almost entirely a demand for more funding for its commercial space program.

9:36 am

NASA’s short statement, in connection to the Obama administration’s decision to suspend all non-ISS related activities with Russia, is almost entirely a demand for more funding for its commercial space program.

To quote:

NASA is laser focused on a plan to return human spaceflight launches to American soil, and end our reliance on Russia to get into space. This has been a top priority of the Obama Administration’s for the past five years, and had our plan been fully funded, we would have returned American human spaceflight launches – and the jobs they support – back to the United States next year. With the reduced level of funding approved by Congress, we’re now looking at launching from U.S. soil in 2017. The choice here is between fully funding the plan to bring space launches back to America or continuing to send millions of dollars to the Russians. It’s that simple. The Obama Administration chooses to invest in America – and we are hopeful that Congress will do the same.

Though I agree with them about accelerating manned commercial space, I can’t help wondering if this suspension of activities was actually instigated to generate this lobbying effort. ISS comprises the bulk of the U.S.’s cooperative effort with Russia, and by exempting that from this suspension the Obama administration essentially exempts practically everything, making the suspension somewhat meaningless.

What the suspension does do, however, is highlight our fragile dependency on Russia, just as Congress begins debate on the 2015 budget.

Six Senators on Wednesday demanded the Air Force open up competition to more companies for launching its military satellites.

9:22 am

The competition heats up: Six senators on Wednesday demanded the Air Force open up competition to more companies for launching its military satellites.

U.S. senators on Wednesday urged the Air Force to allow more competition in the multibillion-dollar market for launching government satellites, citing rising costs and concerns about Russian-made engines that power some of the U.S. rockets.

Lawmakers said the Air Force’s budget plan for fiscal 2015 reduced opportunities for privately held Space Exploration Technologies (SpaceX) and others to gain a foothold in a program now dominated by the two biggest U.S. weapons makers, Lockheed Martin Corp and Boeing Co.

This demand also bodes badly in an indirect way for SLS. It indicates that these senators are beginning to notice the cost benefit of competition and of using the private market. Such a realization is going to eventually leak into their peanut brains about SLS, and that will not do that program any good, especially if the new commercial private companies like SpaceX continue to show success.

A Connecticut community college suspended a student because he dared question the Connecticut governor about his support of gun control.

Fascism: A Connecticut community college suspended a student because he dared question the Connecticut governor about his support of gun control.

The student, Nicholas Saucier, tried to get [Democratic Govenor Dannel] Malloy to answer questions about his support for gun control legislation, which has put Saucier’s ammunition manufacturing business in jeopardy. Saucier followed Malloy to his car after the governor finished speaking at a public forum at Asnuntuck Community College. The exchange took place in October of last year, and was captured on video.

Shortly thereafter, Saucier received notice from the administration that he was suspended on grounds that his “continued presence on campus would present a danger to the persons, property and/or academic process of the College.”

If you follow the link you can watch the video. It is very clear that this student behaved reasonably and without threat. I wonder if maybe the governor made a call to the dean of the college afterward which prompted their actions.

A new analysis of data from Messenger suggests that violent explosive volcanism occurred throughout much of Mercury’s history.

2:06 pm

A new analysis of data from Messenger suggests that violent explosive volcanism occurred throughout much of Mercury’s history.

What is interesting about this result is that previously it was believed that explosive volcanism didn’t happen at all on Mercury.

On Earth, volcanic explosions like the one that tore the lid off Mount St. Helens happen because our planet’s interior is rich in volatiles — water, carbon dioxide and other compounds with relatively low boiling points. As lava rises from the depths toward the surface, volatiles dissolved within it change phase from liquid to gas, expanding in the process. The pressure of that expansion can cause the crust above to burst like an overinflated balloon.

Mercury, however, was long thought to be bone dry when it comes to volatiles, and without volatiles there can’t be explosive volcanism. But that view started to change in 2008, after NASA’s MESSENGER spacecraft made its first flybys of Mercury. Those glimpses of the surface revealed deposits of pyroclastic ash — the telltale signs of volcanic explosions — peppering the planet’s surface. It was a clue that at some point in its history Mercury’s interior wasn’t as bereft of volatiles as had been assumed.

The new conclusions have not only found evidence of explosive volcanism, it found a wide range of ages for these deposits, indicating that the explosive volcanism took place across an extended period of time.

In a vague announcement with unclear ramifications, a NASA memo today suspended “all contact with Russian government officials,” though it exempted all activities in connection with ISS.

In a vague announcement with unclear ramifications, a NASA memo today suspended “all contact with Russian government officials,” though it exempted all activities in connection with ISS.

Given Russia’s ongoing violation of Ukraine¹s sovereignty and territorial integrity, until further notice, the U.S. Government has determined that all NASA contacts with Russian Government representatives are suspended, unless the activity has been specifically excepted. This suspension includes NASA travel to Russia and visits by Russian Government representatives to NASA facilities, bilateral meetings, email, and teleconferences or videoconferences. At the present time, only operational International Space Station activities have been excepted. In addition, multilateral meetings held outside of Russia that may include Russian participation are not precluded under the present guidance.

It appears they are suspending all NASA activities with Russia except ISS, which means that the most important and the bulk of the cooperative work will continue. However, it does mean that the Obama administration has decided to politicize NASA’s operations with Russia in a way that has not been done since the fall of the Soviet Union.

I will be doing a segment on John Batchelor tonight on this developing story.

Climate scientists think the first major El Niño since 1997-1998 is beginning to brew in the Pacific.

9:55 am

Climate scientists think the first major El Niño since 1997-1998 is beginning to brew in the Pacific.

The first sign of a brewing El Niño weather pattern came in January, as trade winds that normally blow from the east reversed course near Papua New Guinea. Barrelling back across the tropical Pacific Ocean, they began to push warm water towards South America. Now climate scientists and forecasters are on high alert.

A major El Niño event — a periodic warming of waters in the eastern equatorial Pacific — could boost temperatures and scramble weather worldwide. The most recent major event, in 1997–98, was linked to thousands of deaths and tens of billions of dollars in damage from droughts, fires and floods across several continents. Yet more than 15 years later, forecasting the timing and intensity of El Niño remains tricky, with incremental improvements in climate models threatened by the partial collapse of an ocean-monitoring system that delivers the data to feed those models.

Note the date of the last event, 1997-1998. This was also the last time the world’s global temperature saw an increase. At the time global warming scientists were saying that global warming would increase the number and severity of El Niño events, which in turn would raise havoc with the climate. Instead, we have gone more than a decade and a half without any significant El Niño event, and the global temperature rise has ceased.

Note also that the article focuses on the difficulty scientists have had in predicting El Niño. These are the same global warming scientists who are also certain they can predict the exact temperature rise for the next two hundred years.

Scientists from the joint European/Russian ExoMars rover mission have narrowed their candidate landing sites to four.

9:43 am

Scientists from the joint European/Russian ExoMars rover mission have narrowed their candidate landing sites to four.

Last week, 60 scientists met at ESA’s European Space Astronomy Centre near Madrid to discuss eight potential sites. On 27 March, they cast an informal vote, and four sites emerged as favourites: Mawrth Vallis, Oxia Planum, Hypanis Vallis and Oxia Palus. An expert working group tasked with recommending a final landing site will now consider the proposals, before announcing a formal shortlist of three or four sites in June. Following detailed studies of the shortlisted sites, the panel will make a single recommendation to ESA and Roscosmos in late 2016.

This is maybe the most risky mission to Mars in decades, as the landing design is coming from the Russians, who have not had a successful interplanetary mission since the era of the Soviet Union, and even then had a 100% failure rate for their missions to Mars. (On a more optimistic note, the European Mars Express mission used a Russian rocket to take off, making it the first Mars mission with Russians participation that actually succeeded.)

One of the factors that has made this mission more risky is the fact that the U.S. was once a participant and backed out very late in the game. The Russians are our replacement, and have had to scramble to catch up.

The German-built comet lander Philae has been successfully reactivated on Rosetta.

Philae will be ejected from the Rosetta mothership in November to latch itself onto the comet’s icy surface with harpoons and screws. The lander has its own suite of science instrumentation to take the first-ever photos and measurements from a comet’s surface. Engineers plan a four-week commissioning phase for Philae to check on its health and activate the lander’s 10 instruments.

The competition heats up: China’s new spaceport and the giant rocket it is being built for.

The combination of the planned rocket, called the Long March 5 — and its derivatives — matched with the Wenchang Launch Center, China’s new sprawling spaceport, underscores the country’s shifting space gears. It enables China’s space station ambitions, while also boosting the nation’s plans for interplanetary exploration, as well as accomplishing human treks to the moon.

Obama declares that “The debate about repealing Obamacare is over.”

Obama declares that “The debate about repealing Obamacare is over.”

Why does the left always want to shut down debate (“The science is settled!” “The debate is over.” “Deniers should be put in prison!”)?

Meanwhile, there is this story: Obamacare takes a life.

The story is heart-rending, and describes how the regulations imposed by Obamacare literally caused this man’s death. As his doctor said, “You can thank Mr. Obama for this.”

But the debates over! What business is it of this doctor or this dead man’s children to complain? The President has spoken. The discussion must now end!

NASA is looking to extend its commercial cargo contracts with SpaceX and Orbital Sciences until 2017.

8:44 am

NASA has extended its commercial cargo contracts with SpaceX and Orbital Sciences until 2017.

Since the notice says that “the modifications would be made ‘at no cost’ to the agency, and that they would be “executed one year at a time,” the extension is probably just designed to give the two companies sufficient time to launch all their cargo missions in the present contracts.

Nonetheless, the posting also said that other companies could compete for NASA’s business during this extension, which leaves the door open for more competition.

A complete list of the Obama administration’s Obamacare.delays.

9:36 am

A complete list of the Obama administration’s Obamacare.delays — so far.

As the article quite correctly notes, “Despite all the Obama administration’s talk about Republicans ‘obstructing’ the health-care law, federal officials and Obamacare administrators have done far more damage to Obamacare by delaying some of its most central provisions.”

Worse, the delays have also done significant damage to the rule of law, since under the law the Obama administration had no right to make these delays in the first place.
