First chemical results from Rosetta

9:24 am

Spectroscopy from Rosetta has identified the make-up of a single dust grain captured by the spacecraft.

For the convenience of communications the science team had dubbed this single grain “Boris.”

[T]hese first results show that among the grain’s components are magnesium and sodium. Since 95 percent of the known observed minerals in comets resemble olivine and pyroxenes – containing a lot of magnesium – the detection of this element is not a big surprise. But, finding sodium in the dust grain, in a refractory mineral phase, has sparked our interest considerably.

The coma and tails of other comets are already known to contain sodium; it was observed in the dust samples returned from Comet Wild 2 by NASA’s Stardust mission, and a prominent example was also the sodium tail of Comet Hale-Bopp that flew past the Sun in April 1997 and which could be seen in the night sky for many weeks. However, by contrast, neither sodium nor magnesium were observed in Comet 67P/C-G dust grains before sampling the inner coma dust. But our dust grain Boris has showed off with clear sodium and magnesium mass peaks in the secondary ion mass spectra that we obtained.

Their next goal is to identify where on the surface of Comet 67P/C-G this sodium came from.

Avalanches on an asteroid

9:12 am

A new analysis predicts that when the asteroid Apophis flies past the Earth in 2029, the close fly-by will cause avalanches on the asteroid.

If asteroids pass close to Earth, they begin to experience the effects of our planet’s gravity. Just like the moon pushes and pulls the oceans, creating the tides, asteroids are susceptible to tidal forces from our planet. To judge what effect this will have on Apophis, scientists need to know what it’s made of. Their best guess is based on photos taken by a Japanese spacecraft named Hayabusa, which took detailed pictures of an Apophis-sized asteroid named Itokawa. Those images revealed that the asteroid wasn’t a solid mass of rock spinning through space, but rather a giant clump of debris held together loosely by gravity. “You look at the [Hayabusa] pictures and you’re like, ‘Uh, that’s a pile of rocks, dude.’ It’s very likely that Apophis is similar,” says astrophysicist Derek Richardson of the University of Maryland, College Park.

To show that Earth’s gravity could cause some of these rocks to tumble, Richardson and his colleagues developed a computer model that allowed them to place virtual sand piles across the surface of a model asteroid with roughly the same dimensions as Apophis. By factoring in the gravity from the asteroid, the tidal force from Earth, centrifugal force caused by the asteroid’s rotation, inertial forces, and other effects, the team was able to predict how the particles on the surface of the asteroid would behave on approach. The results confirm that Earth’s tidal forces would be strong enough to cause tiny avalanches on the asteroid, the team reported online ahead of print in Icarus.

Need I note that there are a lot of uncertainties here? Because they are using what is known about a different asteroid, all of their assumptions about Apophis’s properties in their computer model could be very wrong.

Still, this is interesting, because it does demonstrate that an asteroid could be significantly disturbed simply by flying past a planet.

LADEE impact site located

8:47 am

Lunar Reconnaissance Orbiter has spotted the impact crater formed when engineers sent the probe LADEE crashing into the lunar surface in April 2014.

Compared with asteroid and meteoroid impacts on the moon, LADEE was actually traveling pretty slow, ‘only’ 3,800 miles per hour (1,700 meters per second). That combined with the relatively low mass and density of the spacecraft, a fairly neat crater of only 10 feet (3 meters) across was created. The crater barely registered in LROC’s image resolution, making it a very difficult task to identify the fresh man-made divot.

Doctors flee Obamacare

6:40 pm

Finding out what’s in it: Because of low reimbursements, complex paperwork and regulations, and requirement that doctors treat patients even if they don’t pay for treatment, almost a quarter of a million doctors have opted out of Obamacare.

Remember, it was the Democratic Party and Barack Obama that gave us Obamacare, and only them. They got no help from anyone else, and actually were not interested in anyone else’s advice. They knew better, and the result has been this disaster. Remember this on election day.

Yael Ahn – Chopsticks

6:01 pm

An evening pause: When I was 9 to 11 going to day camp each summer, I had to listen to kids playing this song every day, continually, on the camp piano. I grew to hate it.

This version, however, is absolutely worth listening to and watching, as Ahn adds some percussion, using of all things, chopsticks!

Hat tip to Edward Thelen.

Antares launch failure

3:35 pm

Immediately after lifting off from the launchpad this evening, Orbital Sciences’ Antares rocket exploded, falling back onto the launchpad.

We will have to wait for more details, but regardless this is bad news for Orbital Sciences. The bidding for the second round of cargo contracts to ISS is about to begin, and they will have competition from Sierra Nevada’s Dream Chaser. This accident will hurt them.

I’ve embedded footage of the launch failure below. The damage to the launchpad itself could be the worst aspect of this, as it will cost Orbital Sciences a great deal of money and time to get the pad rebuilt.

Obamacare forces actors’ union to drop older members from healthplan

1:46 pm

Finding out what’s in it: Actors’ Equity Association, the union for stage actors, is dumping its older members from its health insurance plan because of the rising costs of Obamacare.

I guarantee to you that more than 80 percent of the members of this union voted for Obama and support Democratic policies blindly. Now those policies are blind-siding them cruelly, as this quote from the article demonstrates:

“They keep saying there’s a comparable Obamacare option, but there’s not,” one actor said. “I won’t be able to afford to go to [my doctor] anymore.”

Will these liberal actors change their votes? I am pessimistic. From the late seventies to the mid-nineties I worked in the movie industry, and during that time I observed a strong hostility and close-mindedness among this community for any political ideas not labeled “Democratic.” They are the most partisan people I have ever met, and will probably carry that partisanship to their graves — which is likely to happen sooner now that Obamacare is there to “help” them.

The Grand Tetons used as the Obama adminstration’s private playground

12:46 pm

The law is for the little people: Obama administration officials, including Vice-President Joe Biden, have been routinely using a closed lodge in Grand Teton National Park for their personal and family vacations.

Vice President Biden and several top White House officials have vacationed with their families at the same log cabin in Grand Teton National Park. Located on Jackson Lake, the rustic getaway is the perfect escape from the fast-paced Washington grind. The cabin also happens to be owned by the federal government, and was banned 20-some years ago by the National Park Service for anything other than “official use.”

This abuse is really not restricted to just elected officials. Park officials also often take advantage of their positions of power to use park facilities for their own pleasure that they ban the public from using.

Obamacare website easy to hack

10:02 am

It appears the wrong people can find out what’s in it: The Obamacare website, which has cost taxpayers hundreds of millions if not a billion dollars (depending on who you ask), turns out to be very easy to hack.

The website requires those enrolling for ObamaCare to supply their first and last name, home address, social security number and paying information — including credit card data. Lamar Smith, chair of the committee looking after the security of the website, said there had been hearings on the “lack of security” around the website. He told Fox News: “What we”ve discovered is that it seems to be easy to be hacked, the security is not secure.

It appears the site was hacked on July 8 but the hack wasn’t discovered until August 25. That gave the hackers almost two months to rummage through the personal files of Americans. How nice.

NASA treats Congress like a doormat, again

9:34 am

Stupid: More than a month after publicly awarding commercial crew contracts to SpaceX and Boeing, NASA has yet to brief Congress on the reasons for its decision.

“To date, the Committee has not been briefed on the source selection, nor has it received the source selection statement, despite the fact that the offerors have been briefed, details were released to the press, the [Government Accountability Office] is now involved; and NASA has decided to proceed with the contracts,” Reps. Lamar Smith (R-Texas) and Steven Palazzo (R-Miss.) wrote in a letter to NASA Administrator Charles Bolden dated Oct. 21. Smith and Palazzo chair the House Science Committee and House Science space subcommittee, respectively.

“We hope that NASA will not expect taxpayers to blindly fund billion-dollar programs absent any information related to the procurement or contract,” wrote Smith and Palazzo, who are ardent supporters of the Space Launch System, major contractual details of which were only finalized this year and have not yet been made public.

These elected officials are not NASA’s allies when it comes to commercial space, so giving them too much information is probably dangerous. At the same time, the choice of Boeing was certainly done to ease their concerns, and keeping them out of the loop is only going to turn them against the commercial space contracts. It serves no purpose. NASA should instead be trying to show them why picking SpaceX and Boeing made sense, and how these two multi-billion dollar contracts will bring many jobs to their districts.

If NASA doesn’t do this basic political massaging, these guys are simply going to try to cut commercial space out when it comes time to negotiate the budget, as they have already tried to do several times in the past.

But then, when it comes to politics this behavior by the Obama administration is par for the course. They might have the right idea, farming out space exploration to the private sector, but their political implementation has often left much to be desired.

Third launch for China in a week

9:17 am

The competition heats up: China today launched its third spacecraft in a week with the launch Monday of a military satellite.

Monday’s mission was the third Chinese space launch in a week, coming after the Oct. 20 liftoff of the Chinese military’s Yaogan 22 reconnaissance satellite and the Oct. 23 launch of a demonstrator probe on a looping flight around the moon and back to Earth to verify technologies for use on a planned mission to retrieve and return lunar samples. Overall, the launch of Shijian 11-08 marked the ninth Chinese space launch of 2014.

Largest sunspot in a quarter century spews flares

8:31 pm

The largest sunspot seen in about a quarter century produced another powerful X-class flare today, the sixth in less than a week.

This was the sixth X-class solar flare from NOAA 2192, a record for the number of X-class flares generated by a single group so far this solar cycle. It was also the fourth X-class flare since last Friday, continuing a period of intense flaring activity. This sunspot group has grown again a bit, and maintains its magnetic complexity. A degradation of the HF radio-communication was observed over South-America, the Caribbean, and West-Africa.

The last sentence is referring to some radio communications blackouts that have occurred in these areas because of the flares. For more information about the sunspot itself, go here.

And in case you hadn’t noticed, as predicted by many doomsday fear-mongers in the science community, our technological civilization was destroyed by these flares and we are now all dead.

Vulnerable Senate Democrats are all Obama rubber-stamps

4:03 pm

A vote for Obama: Every single one of the most vulnerable Democrats running for the Senate voted with Obama more than 96 percent of the time.

As senior writer Shawn Zeller writes in this week’s CQ Weekly cover story, Democrats … have been distancing themselves from Obama on the campaign trail not in votes on the Senate floor — whether it be Mark Udall of Colorado, Mark Pryor of Arkansas or Mary L. Landrieu of Louisiana: “Udall disagreed just once, on a Pennsylvania state judge’s nomination to a federal district court. Pryor parted with Obama three times, and Landrieu four, but only one of those votes was on a policy matter. In July, Landrieu voted against Obama’s request for $2.7 billion to deal with the surge of Latin American children entering the U.S. illegally.” Indeed, all of the most vulnerable Democrats voted with President Obama at least 96 percent of the time on the 120 votes on which Obama has urged a “yes” or “no” vote.

There are many take-aways you could get from this story, but I want to emphasis one: These Democratic candidates are all liars and consider the voters stupid. By claiming in their campaigns and debates that they are independent of Obama they are telling us that they think you are too stupid to see through their lies and will vote for them anyway.

Bottom line: a vote for a Democrat this election is a vote for the policies that Barack Obama has foisted on this country the past six years. Is that what we really want?

Note: Sorry for the lack of posts today, but up until now I have honestly not seen anything in the news that I consider worth posting.

Obamacare causes AIDS drug prices to skyrocket

9:56 pm

Finding out what’s in it: Because Obamacare has forced AIDS patients off their old health plans, their cost for drugs has skyrocketed.

I wonder how many of these patients, most of whom are gay and thus mostly liberal and supporters of the Democratic Party, will continue to vote Democratic. I wonder if they will finally begin to connect the dots, and realize that their loyalty to the Democratic Party might literally be killing them.

Kid makes interception and scores and is punished

10:14 am

Sick world: An 8-year-old boy took an interception in for a touchdown in a kid’s football game and his team is fined and his coach is suspended.

CBS 46 reports the Lawrenceville Black Knights were winning against their opponents, 32-0, in the fourth quarter. Burrell then intercepted a pass and went through with the touchdown, failing to comply with the league’s mercy rule. That six-point score caused the Georgia-based team to surpass the 33-point rule, which earned the coach a week-long suspension and the team a $500 fine.

Burrell’s mothers, Brooke Burdett, told CBS 46 that she and her son were “beyond excited” at first, before learning of the fine. “He had no idea” Burdett said. “This is his first year. This was his first touchdown. He is an 8-year-old boy making a pick-six.”

Heaven forbid we have an 8-year-old boy achieve something cool, get thrilled about it, and think he can do great things in the future. Noooooooo, we have to squelch that sense of worth and achievement so that the failures in life won’t have hurt feelings.

These idiotic parents and the people who run this league obviously don’t remember what it is like to play kids’ sports. Boys aren’t crushed by these kinds of defeats. Instead, most boys use the experience to figure out how they can win the next time. By denying them this lesson in life you act to cripple them.

The IRS steals property and cash

6:27 pm

Theft by government: The IRS admits to seizing hundreds of thousands of dollars of private assets, without any proof of illegal activity, merely because there is a law that lets them do it.

Using a law designed to catch drug traffickers, racketeers and terrorists by tracking their cash, the government has gone after run-of-the-mill business owners and wage earners without so much as an allegation that they have committed serious crimes. The government can take the money without ever filing a criminal complaint, and the owners are left to prove they are innocent. Many give up and settle the case for a portion of their money. “They’re going after people who are really not criminals,” said David Smith, a former federal prosecutor who is now a forfeiture expert and lawyer in Virginia. “They’re middle-class citizens who have never had any trouble with the law.”

The article describes several specific cases, all of which are beyond egregious and are in fact entirely unconstitutional. The Bill of Rights is very clear about this: The federal government cannot take private property without just compensation.

ISS data lowers radiation risk for humans in space

7:28 pm

Good news: Data collected on ISS for the past decade now suggests that the human body does a better job of shielding its internal organs from space radiation than previously believed.

For an astronaut working inside the space station, the overestimate was about 15 percent — a fairly close correlation given that the station’s exterior shell provides much of the protection needed.

But for astronauts working outside the station, the radiation absorption measured was substantially less than what had been registered by the personal dosimeters worn by astronauts. “Measurements of a personal dosimeter dramatically overstate the exposure of an astronaut, in the worst case by a factor of three,” according to a summary of the results by a Euro-Russian team. “[I]n an outside exposure the self-shielding of the human body is very effective. … [T]he effective dose equivalent is less than 30 percent higher than in an inside exposure.”

In other words, humans could fly 30 percent longer in space with the present shielding and suffer far less exposure than expected. Though this data is for operations in low Earth orbit, it still provides a strong counter to the bad news recently released about the high amounts of dangerous radiation expected in interplanetary space due to the Sun’s recent low sunspot activity. Even if radiation levels are higher, the human body is more resilient than expected. Interplanetary space travel is still possible.

Lawsuit could delay Cygnus cargo flight in April

7:20 pm

A lawsuit between Orbital Sciences and one of its subcontractors threatens to delay the planned April launch of Antares/Cygnus to ISS.

The lawsuit, filed Oct. 21 with the U.S. District Court for the Eastern District of Virginia, centers around a roughly $2 million contract Orbital Sciences awarded in 2013 to defendants Integrated Systems and Machinery of Smithtown, New York, and its owner, Kevin Huber. The contract called for Huber’s company to build new gimbals and cylinders for the hydraulic system used by the slow-moving, truck-like Transporter Erector vehicle that hauls Orbital’s Antares cargo rocket and Cygnus space freighter out of their Wallops Island, Virginia, hangar and raises them vertical at their Mid-Atlantic Regional Spaceport launch pad over a kilometer away.

Orbital’s third cargo run to the ISS — which at press time was still slated to launch Oct. 27 — can proceed without the withheld hardware. However, Orbital is obligated under an agreement with the Mid-Atlantic Regional Spaceport’s host state to upgrade the Transporter Erector before launching its fourth contracted cargo run, the debut of a bigger, heavier Cygnus cargo tug.

I don’t really expect this dispute to delay the April launch. What we have here is a case of hardball negotiations, with the subcontractor using the situation to try to squeeze more money out of Orbital Sciences. In the end they will come to an agreement and the upgrade will be installed.

Falcon 9 first stage to land on floating platform

7:11 pm

The competition heats up: During an event at MIT on Friday Elon Musk revealed that SpaceX will to try to land first stage of the next Falcon 9 launch on a floating platform.

“We actually have a huge platform that’s being constructed in a shipyard in Louisiana right now,” Musk said in the interview, which was webcast live. He described the platform as about 90 meters long by 50 meters wide. “We’re going to try and land on that on the next flight.”

If the stage successfully lands on the platform, Musk said, it could potentially fly again. He put the odds of success at no greater than 50 percent for this particular attempt, but was more optimistic about the company’s chances of landing on the platform on a future mission. “There’s at least a dozen launches that will occur over the next 12 months,” Musk said. “I think it’s quite likely — probably 80 to 90 percent likely — that one of those flights will be able to land and refly.”

Based on everything this company has promised and later actually delivered, I would be willing to bet that they will do exactly as Musk says, and that sometime in the next year they will successfully recover the first stage of their rocket, an achievement that will shake the entire launch industry to its foundations.

Democrats demand the right to regulate internet speech

5:26 pm

Fascists: The Democrats on the Federal Election Commission on Friday called for the heavy regulation of speech on the internet.

In a surprise move late Friday, a key Democrat on the Federal Election Commission called for burdensome new rules on Internet-based campaigning, prompting the Republican chairman to warn that the Left wants to regulate conservative political sites and even news outlets like the Drudge Report.

Democratic FEC Vice Chair Ann M. Ravel announced plans to begin the process to win regulations on Internet-based campaigns and videos, currently free from most of the FEC’s rules. “A reexamination of the commission’s approach to the internet and other emerging technologies is long over due,” she said.

And if you vote for these thugs, you identify yourself as someone supporting fascism.
