Did Stardust capture stardust?

Scientists now believe that the spacecraft Stardust captured seven particles from interstellar space during its seven year journey.

Inside the canister, a tennis racket-like sample collector tray captured the particles in silica aerogel as the spacecraft flew within 149 miles (about 240 kilometers) of a comet in January 2004. An opposite side of the tray holds interstellar dust particles captured by the spacecraft during its seven-year, three-billion-mile journey.

Scientists caution that additional tests must be done before they can say definitively that these are pieces of debris from interstellar space. But if they are, the particles could help explain the origin and evolution of interstellar dust. The particles are much more diverse in terms of chemical composition and structure than scientists expected. The smaller particles differ greatly from the larger ones and appear to have varying histories. Many of the larger particles have been described as having a fluffy structure, similar to a snowflake. [emphasis mine]

It appears that for these seven particles, the scientists conclude they are likely interstellar particles because of the speed in which they were traveling when captured as well as their make-up. Both suggest an origin outside the solar system.

However, we should be cautious about this. The data still remains tenuous and preliminary. More work obviously needs to be done to pin this down definitively. More information here.

New footage of the Falcon 9 soft spashdown

SpaceX has released new additional footage showing the controlled descent and soft spash down of the first stage of its Falcon 9 rocket during its July launch. I’ve posted it below.

As they note on their webpage, “Towards the end of the video, the camera operator attempted to zoom in and unfortunately lost sight of the stage and was unable to capture the tip over into the water.” Nonetheless, the controlled nature of the stage’s descent says that they succeeded, and need only try to do this over land to prove they can recover their first stage.

IRS lets contractors rummage through taxpayer data

Does this make you feel secure? An inspector general report found that the IRS allowed contractors access to personal taxpayer information without doing the required background checks required by IRS policy.

Contractors who have access to sensitive information, which also includes employee and law enforcement data, must undergo a background check if they’re with the IRS for more than six months.

But the inspector general’s audit found five contracts where contractors had not had any background checks out of the 28 total contracts reviewed. In one of those cases, a contractor working on printing and mailing tax forms was given a disk containing 1.4 million taxpayer names, Social Security numbers and other personal information. A separate contract, for couriers, had given a daily route to an ex-convict who served more than 20 years for arson, the report added. In another 12 cases, IRS staffers had started background checks for contractors, but contractors were allowed to start working before those investigations had concluded.

“It was the grossest incompetence.”

The IRS takes more than two years to issue a refund check because of its own stupidity.

This paragraph best sums up the entire idiocy:

Dinesen [representing the citizen] immediately contacted the collection division. He was told they had no record of the return. The identity theft unit was handling it, and the collection division’s computers weren’t capable of interfacing with the identity theft unit’s computers. “I asked if he could just call the identity theft unit to confirm the return had been filed. He said he couldn’t. His explanation for why not boiled down to, ‘We don’t do that,’” Dinesen said.

The agent agreed to suspend collection actions against Boka Gonzalez while Dinesen tried to resolve the case. “He also asked me to give him a call if I got any information from the identity theft unit. It seemed ridiculous to me that one part of the IRS would ask an outside person to keep him informed of what another part of the IRS was doing, but that was the level of dysfunction we were dealing with,” Dinesen said.

Read the whole story. It is horrifying. And remember, this is a case where the IRS was simply incompetent. Imagine the harm they could do if they wanted to do harm, or were ordered to do so by our political leaders. Thank God such things never happen!

The IRS stonewalls a judge

Working for the Democratic Party: Required by a judge to explain in detail in 30 days the destruction of its emails, the IRS has instead provided nothing more than shallow platitudes.

The author of the article above is very confident that, based on his past history, the judge will come down very hard on the IRS for its stonewalling. I pray that he is right.

Michael Mann’s court suit under attack

Good news: Groups from across the political spectrum are expressing their opposition to Michael Mann’s court suit against his critics.

On Monday, The Reporters Committee for the Freedom of the Press — along with 26 other groups including The Washington Post, Bloomberg and Fox News — filed an “amici curiae,” or “friend of the court,” brief with the D.C. Court of Appeals. An amici curiae is a brief submitted to a court to raise additional points of view to sway a court’s decision.

“While Mann essentially claims that he can silence critics because he is ‘right,’ the judicial system should not be the arbiter of either scientific truth or correct public policy,” the brief states, adding that “a participant in the ‘rough-and-tumble’ of public debate should not be able to use a lawsuit like this to silence his critics, regardless of whether one agrees with Mann or defendants.”

Just as Mark Steyn and Rand Simberg said it, I will say it also: Michael Mann is a fraud. He has no idea what it means to be a scientist, and should have been fired by his university after his climategate emails were uncovered. Instead, his university’s investigation was a whitewash and as much a fraud as Mann is.

Russia to build new satellite communications cluster

The competition heats up: The Putin government’s newly released draft plan for Russia’s space industry includes the development of a new communications satellite constellation.

In addition to encrypted mobile communications, the Ellips satellites will support air-traffic control and traditional fixed communications. Reflecting its dual (civilian and military) application, the Ellips project would be funded jointly by the Russian space agency, Roskosmos, and by the Russian Ministry of Defense at a price tag of 65.6 billion rubles to develop and deploy the constellation.

The article then goes on to detail at length the problems the Russian communications satellite industry has had for the past two decades, including their inability to build satellites that will last in orbit as long as their competitors.

Another look at why ULA’s CEO stepped down

Why did ULA’s CEO step down, and did SpaceX or the Atlas 5’s dependence on Russian engines play a part?

Very worthwhile reading, as it suggests that not only is the competition from SpaceX a major factor, so was ULA’s effort to monopolize the military launch industry as well as monopolize its access to the Russian engines, denying their use by Orbital Sciences.

And to this I say, thank god for competition. It always shakes things up in a good way.

Private lunar lander completes test landing

The competition heats up: One of the competitors in the Google Lunar X-Prize has successfully completed its first landing test, on Earth, of its lander.

The article does not really provide a lot of information about the test itself, spending most of its copy describing what the test was supposed to do. Still, they did complete it successfully, which means they will now revise, rebuild, and retest.

Worldview-3 in orbit

The competition heats up: Worldview-3, launched yesterday, has been successfully activated and can now provide commercial and private customers images of the Earth with resolution comparable to military intelligence satellites.

The sensor package on WorldView-3 will be able to image objects with a ground sample distance of 31 cm (12 in.). “So we can tell you if it’s a truck, SUV or a regular car,” says Kumar Navulur, director of next-generation products at DigitalGlobe. “If there’s a high contrast we can identify features of fine scale,” he adds, giving examples of markings in a parking lot or “a tomato plant in a backyard in Asia.”

Obviously, this has both good and bad possibilities. Nonetheless, its availability increases the value of the space-based industry.

Maps showing the territories of the Kurds and the Islamic State

Since I think it useful to have a rough geographical understanding of the situation, I have been digging around to find some maps that will outline the territories controlled by the both the Kurds and the Islamic State (also known as the Islamic State of Iraq and Syria [ISIS]), including the areas of dispute. This link provides the best selection I’ve found so far.

Based on these maps, I wonder when ISIS will start moving into next door Iran, as its western regions are adjacent to their present holdings.

The flight of gifted engineers from NASA

Rather than work in NASA, the best young engineers today are increasingly heading to get jobs at private companies like SpaceX and XCOR.

It is a long article, worth reading in its entirety, but this quote will give the essence:

As a NASA engineering co-op student at Johnson Space Center, Hoffman trained in various divisions of the federal space agency to sign on eventually as a civil servant. She graduated from college this year after receiving a generous offer from NASA, doubly prestigious considering the substantial reductions in force hitting Johnson Space Center in recent months. She did have every intention of joining that force — had actually accepted the offer, in fact — when she received an invitation to visit a friend at his new job with rising commercial launch company SpaceX.

Hoffman took him up on the offer, flying out to Los Angeles in the spring for a private tour. Driving up to the SpaceX headquarters, she was struck by how unassuming it was, how small compared to NASA, how plain on the outside and rather like a warehouse.

As she walked through the complex, she was also surprised to find open work areas where NASA would have had endless hallways, offices and desks. Hoffman described SpaceX as resembling a giant workshop, a hive of activity in which employees stood working on nitty-gritty mechanical and electrical engineering. Everything in the shop was bound for space or was related to space. No one sat around talking to friends in the morning, “another level from what you see at NASA,” she said. “They’re very purpose-driven. It looked like every project was getting the attention it deserved.”

Seeing SpaceX in production forced Hoffman to acknowledge NASA might not be the best fit for her. The tour reminded her of the many mentors who had gone into the commercial sector of the space industry in search of better pay and more say in the direction their employers take. She thought back to the attrition she saw firsthand at Johnson Space Center and how understaffed divisions struggled to maintain operations.

At NASA young engineers find that they spend a lot of time with bureaucracy, the pace is slow, their projects often get canceled or delayed, and the creative job satisfaction is poor. At private companies like SpaceX, things are getting built now. With that choice, no wonder the decision to go private is increasingly easy.

NASA headquarters staff votes to unionize.

NASA’s bureaucracy marches on: The staff at NASA headquarters today voted to unionize.

“This successful vote will allow us to work with management to improve working conditions for NASA support and administrative staff here at NASA headquarters, thereby improving operations, saving money, and retaining an engaged and professional workforce,” said Tifarah Thomas, a program specialist within NASA’s Office of the Chief Health & Medical Officer. Professional support specialists at NASA headquarters include budget analysts, policy analysts, administrative specialists, secretaries, and others.

NHPA currently represents nearly 200 engineers and scientists at NASA in Washington. The combined unit, including the professional support specialists who voted today for IFPTE representation, will now represent more than 500 workers at the headquarters of America’s space agency. IFPTE also represents engineers and scientists at NASA labs and research facilities from coast-to-coast.

Anyone with the slightest objectivity knows that the working conditions for federal employees in Washington is glorious, with pay about double what everyone else in the country makes and benefits far exceeding even the best private packages. In addition, the hours are great and just slightly longer than what my generation would have called bankers’ hours. Moreover, if I can be blunt, these engineers are mostly paper pushers. They are not the one’s designing and building anything that might fly in space. Their only reason to unionize now is because they see a threat to their cushy jobs with the advent of private space and are organizing to secure their unneeded positions.

It ain’t gravity holding this asteroid together

Astronomers have discovered that near Earth asteroid 1950DA is spinning so fast that gravity can’t hold it together. Instead, it is kept whole by cohesive forces called van der Waals forces, predicted but never detected before on an asteroid.

This is the coolest factoid from the article, however:

“We found that 1950 DA is rotating faster than the breakup limit for its density,” said Rozitis. “So if just gravity were holding this rubble pile together, as is generally assumed, it would fly apart. Therefore, interparticle cohesive forces must be holding it together.”

In fact, the rotation is so fast that at its equator, 1950 DA effectively experiences negative gravity. If an astronaut were to attempt to stand on this surface, he or she would fly off into space unless he or she were somehow anchored.

The important take away from this discovery is that it will be very easy to break this kind of asteroid up, turning a large and big threat into a collection of small but harmless rocks.

Iraqi Muslims celebrate persecution of Christians

The bigoted religion of peace: An Christian Iraqi refugee describes how the Muslims in Mosel celebrated the arrival of ISIS and the expulsion of Christians.

An Iraqi Christian who fled for his life from Mosul says that his Muslim neighbors welcomed the Islamic State of Syria and Iraq (ISIS) and told him “this land belongs to Islam.”

“We left Mosul because ISIS came to the city. The (Sunni) people of Mosul embraced ISIS, and drove the Christians out of the city,” the unnamed Christian refugee, who reportedly fled from Mosul to Lebanon, told Lebanese LBC/LDC TV in a July 30 interview translated by Middle East Media Research Institute (MEMRI).

And then there’s this: A mob of Muslims on the Temple Mount in Jerusalem force the closure of that site to Jews.

Watch the video below the fold and tell me who you think is bigoted and expressing hatred. As one of the Jews notes with humor near the beginnin of the video, “Look, three Jews, how many Arabs; they are calling to G-d, they are praying to G-d because of us, it’s wonderful. You see what we did?”

Things get more and more heated, beginning around 9:00, as they begin to approach the Temple Mount itself. Note that all these guys are doing is trying to take a tour of the site.

Another former SpaceX employee sues

SpaceX has been hit by its second lawsuit in a week from a former employee.

The lawsuit, filed in Los Angeles Superior Court, alleges that SpaceX supervisors impose schedules on their employees that make it impossible for them to take statutorily required rest periods every four hours or first or second meal breaks as required by California law.

I consider this suit a bigger threat to the company than the first. The first suit merely claimed that the company didn’t give its fired employees the 60 day warning as required by law. If they win, they will get some payments, but the company will be able to continue as before.

This second suit, if successfully, could force the company to change its aggressive culture, where employees are expected to work very hard, sometimes 60-80 hour weeks, to make things happen quickly. While those work hours might seem abusive to some, to most of the people working there it is what they want to do. A successful lawsuit here could force the company to literally stop them from working. The conditions then might be more relaxed, but the ability to make progress will be stymied, and the costs for making that progress will go up considerably.

ULA CEO steps down

Faced with stiff competition from SpaceX, United Launch Alliance (ULA) announced today a change in leadership.

United Launch Alliance has named a new president and chief executive to replace Michael Gass, who led the Atlas and Delta rocket company since its inception in 2006. Gass will be replaced effective immediately as president and CEO by Tory Bruno, an executive at Lockheed Martin Corp., which formed ULA in December 2006 in a 50-50 joint venture with Boeing Co., ULA said in a statement Tuesday. Gass is retiring at the end of the year, according to ULA.

Despite Gass’s planned retirement, the abrupt nature of his departure has everything to do with the competition from SpaceX, something that every single article about this change at ULA noted.

Giant Greek tomb discovered

Archeologists have uncovered the largest tomb ever discovered in Greece and think it is linked to the reign of Alexander the Great.

The tomb, dating to around 300 BC, may have held the body of one of Alexander’s generals or a member of his family. It was found beneath a huge burial mound near the ancient site of Amphipolis in northern Greece. Antonis Samaras, Greece’s prime minister, visited the dig on Tuesday and described the discovery as “clearly extremely significant”.

A broad, five-yard wide road led up to the tomb, the entrance of which was flanked by two carved sphinxes. It was encircled by a 500 yard long marble outer wall. Experts believe a 16ft tall lion sculpture previously discovered nearby once stood on top of the tomb.

The excavations began in 2012, and by this month hope to identify who actually was buried there.

The weather is finally changing on Titan

New Cassini images of Titan have spotted the appearance of clouds above the planet’s northern seas, suggesting the overdue onset of the summer storms that climate models have predicted.

For several years after Cassini’s 2004 arrival in the Saturn system, scientists frequently observed cloud activity near Titan’s south pole, which was experiencing late summer at the time. Clouds continued to be observed as spring came to Titan’s northern hemisphere. But since a huge storm swept across the icy moon’s low latitudes in late 2010, only a few small clouds have been observed anywhere on the icy moon. The lack of cloud activity has surprised researchers, as computer simulations of Titan’s atmospheric circulation predicted that clouds would increase in the north as summer approached, bringing increasingly warm temperatures to the atmosphere there.

“We’re eager to find out if the clouds’ appearance signals the beginning of summer weather patterns, or if it is an isolated occurrence,” said Elizabeth Turtle, a Cassini imaging team associate at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland. “Also, how are the clouds related to the seas? Did Cassini just happen catch them over the seas, or do they form there preferentially?”

Any conclusions drawn at this time about the seasonal weather patterns of Titan must be considered highly uncertain, since we only have been observing the planet for a period that only covers one very short portion of its very long 30 year-long year.

A blue flask of viruses

The story of the discovery of Ebola.

The next day—September 29—the package arrived: a cheap plastic thermos flask, shiny and blue. I settled down with Guido Van Der Groen—a shy, funny, fellow Belgian aged about thirty, a few years older than I—and René Delgadillo, a Bolivian postdoc student, to open it up on the lab bench. Nowadays it makes me wince just to think of it. Sure, we were wearing latex gloves—our boss insisted on gloves in the lab but we used no other precautions, no suits or masks of any kind.

We didn’t even imagine the risk we were taking. Indeed, shipping those blood samples in a simple thermos, without any kind of precautions, was an incredibly perilous act. Maybe the world was a simpler, more innocent place in those days, or maybe it was just a lot more reckless.

Unscrewing the thermos, we found a soup of half-melted ice: it was clear that subzero temperatures had not been constantly maintained. And the thermos itself had taken a few knocks, too. One of the test tubes was intact, but there were pieces of a broken tube—its lethal content now mixed up with the ice water—as well as a handwritten note, whose ink had partially bled away into the icy wet.

Read it all. The excerpt is from a book length memoir that looks to me to be a very worthwhile read.

The Milky Way’s most distant stars

Astronomers have discovered the two most distant stars of the Milky Way.

Both stars are red giants, aging suns that shine so brightly observers can see them from afar. One star is about 890,000 light-years from Earth in the constellation Pisces—33 times farther from the Milky Way’s center than we are and well beyond the edge of the galactic disk. The only other Milky Way member at a comparable distance is a small galaxy named Leo I, which orbits ours at a distance of 850,000 light-years. If the star in Pisces revolves on a circular path as fast as we do, it takes some eight billion years to complete a single orbit around the galaxy. That’s more than half the age of the universe.

The other newfound star is about 780,000 light-years distant in the constellation Gemini and more than a million light-years from the other star. For comparison, the previous record-breaking individual star was only about half a million light-years from Earth.

Both stars are so far outside the galaxy’s disk that it is quite possible that they are not part of the Milky Way at all.

NASA admits that it is struggling to meet the 2017 launch date for SLS

Delays in the construction of Orion’s European-built service module as well as cracks in the spacecraft’s heat shield are threatening the planned 2017 launch date for Orion’s first test flight, unmanned, beyond Earth orbit.

Note that this program, costing anywhere from $10 to $20 billion, is only building a handful of capsules for flying three or four test flights. Beyond that, there is no money.

I have predicted this before, and I will predict it again: SLS will never take any humans anywhere. The cost is too high, the bureaucracy too complex, and the schedule is too slow. It will vanish when the new private companies begin flying humans into space in the next three years.
