How scientists are using the Kelly twins during Scott Kelly’s year-long mission to ISS to learn how weightlessness effects the human body

9:21 am

Link here. Scott Kelly launches today to the station to begin the flight.

The article’s headline and initial focus on how the Kellys’ privacy rights might interfere with the research seems inappropriate. It is as if the author and Nature wanted to spin the story to force the Kellys to reveal private medical data they would prefer to keep private.

The real story the article tells is that an incredible wealth of knowledge about microgravity will be gained by this flight, because the Kellys are both participating. And depending on what is learned when their entire genomes are sequenced, we might also be able to study that fully as well.

Air Force demanded too much in its SpaceX certification process

4:50 pm

In the heat of competition: A military review of the Air Force’s certification process of SpaceX has found that the Air Force has demanded far more changes from the company than were justified or proper.

The report, prepared by former Air Force Chief of Staff General Larry Welch, said the Air Force treated the process like a detailed design review, dictating changes in SpaceX’s Falcon 9 rocket and even the company’s organizational structure. That approach resulted in over 400 issues that needed to be resolved, which was “counterproductive” to a national policy aimed at encouraging competition in the sector.


In fact, the process was intended to show that SpaceX met overall requirements to launch military satellites, not carry out the more detailed review required for each launch on a case-by-case basis, he said.

The review also concluded that SpaceX was too resistent to any proposed changes.

SpaceX might have been too resistent, but this report confirms my suspiciion that the Air Force purposely created hoops for SpaceX to jump through because the Air Force really didn’t want to have to deal with SpaceX and wanted to make it too difficult for them to be approved.

Dark matter is even more of a mystery that expected

4:36 pm

The uncertainty of science: Using the Hubble and Chandra space telescopes astronomers have discovered that dark matter is not only invisible to direct observation, it is invisible to itself!

In this new research, Harvey and his team realized just how invisible this stuff is, even to itself. As two galactic clusters collide, the stars, gas and dark matter interact in different ways. The clouds of gas suffer drag, slow down and often stop, whereas the stars zip past one another, unless they collide — which is rare. On studying what happens to dark matter during these collisions, the researchers realized that, like stars, the colliding clouds of dark matter have little effect on one another.

Thought to be spread evenly throughout each cluster, it seems logical to assume that the clouds of dark matter would have a strong interaction — much like the colliding clouds of gas as the colliding dark matter particles should come into very close proximity. But rather than creating drag, the dark matter clouds slide through one another seamlessly.

I guarantee that this result is not definitive. The data here is on the very edge of reality, built on too many assumptions. We know that something undetected as yet is influencing the motions of galaxies, but what exactly it is remains completely unknown. These results only make the mystery more mysterious.

Stay tuned for photo tour of Vandenberg

4:23 pm

I am presently at Santa Barbara Airport waiting for my flight home to Tucson after spending the day at Vandenberg Air Force Base. After Steve and Jessica Tullino of the Vandenberg Section of the AIAA gave me a tour of the base, including a close look at one launchpad, I then was their speaker at their section’s luncheon meeting.

Anyway, I took a bunch of pictures and plan to post these sometime tonight or tomorrow. Stay tuned.

GAO denied access to Webb telescope workers by Northrop Grumman

11:04 pm

In a report as well as at House hearings today the GAO reported that Northrop Grumman has denied them one-on-one access to workers building the James Webb Space Telescope.

The interviews, part of a running series of GAO audits of the NASA flagship observatory, which is billions of dollars overbudget and years behind schedule, were intended to identify potential future trouble spots, according to a GAO official. But Northrop Grumman Aerospace, which along with NASA says the $9 billion project is back on track, cited concerns that the employees, 30 in all, would be intimidated by the process.

To give Northrop Grumman the benefit of the doubt, these interviews were a somewhat unusual request. Then again, if all was well why would they resist? Note too that the quote above says the cost of the telescope project is now $9 billion. That’s a billion increase since the last time I heard NASA discuss Webb. If the project was “back on track: as the agency and Northrop Grumman claim, than why has the budget suddenly increased by another billion?

NASA has decided to grab an asteroid rock rather than bag an asteroid

10:43 pm

Rather than try to bag an entire small asteroid with an unmanned probe and bring that back to Earth, NASA has decided to send an unmanned probe into orbit around an asteroid and use it to grab one of the asteroid’s boulders.

The $1.25 billion mission, which is planned to launch in December 2020, would send a robotic spacecraft for a rendezvous with an asteroid in 2022. After touching down on the asteroid’s surface, the spacecraft would snatch a boulder several meters across. The spacecraft would then orbit the asteroid for up to 400 days, testing out an idea for defending Earth from a catastrophic asteroid impact: using the spacecraft’s own gravitational field to subtly alter the asteroid’s orbit. Next, the spacecraft would bring the snatched rock back to Earth’s vicinity in 2025. Finally, as part of preparations for a possible mission to Mars, astronauts would visit and examine the rock for some 25 days, using the planned Orion spacecraft to make the trip.

From both a science perspective as well as a manned space perspective, the unmanned part of this plan is a very good idea. Whether it will get funded depends upon Congress, since its roots go back to President Obama’s April 2010 commitment to send astronauts to an asteroid by 2025. Such a commitment was never really realistic, so it has devolved to capturing a rock and sending astronauts to visit it, thus meeting Obama’s commitment in a Potemkin Village sort of way.

Much better to bring the rock back to Earth orbit where it can be captured and brought to ISS by any number of vehicles and studied there. Whether Congress will fund this in the manner proposed in order to help Obama meet his commitment however remains very doubtful.

A drastic drop in complaints immediately after San Diego outfitted its police with body cameras

4:54 pm

Surprise, surprise! Immediately after San Diego outfitted its police force with 600 body camera the number of complaints plunged.

The report, which took one full year into account, found that complaints against police have fallen 40.5 percent and use of “personal body” force by officers has been reduced by 46.5 percent. Use of pepper spray has decreased by 30.5 percent.

Two benefits can be seen immediately. First, the police are being harassed less from false complaints. Second, and more important, the police are finding ways to settle most disputes without the use of force, which means they are abusing their authority less.

These statistics do confirm what many on both the right and the left have begun to believe in recent years, that the police have been almost certainly using force against citizens inappropriately too often. In San Diego at least the cameras are serving to stem this misuse of authority.

College punishes students for sexist chanting at party, even those not there

1:40 pm

Fascists: The University of Mary Washington has punished its entire rugby team of 46 because 8 attended a party where some had participated in “sexist chanting.”

The microaggression unfolded last November at a house party near the Fredericksburg, Virginia, campus, according to Jezebel’s Erin Gloria Ryan. Some students, likely drunk, sang a demeaning song about raping corpses and “wiggling it” inside whores—inappropriate stuff, to be sure, though not really targeted at a specific entity in a threatening way. The chant apparently has its origins in rowdy “pub” songs. It’s a curious tradition, though not one intended to inspire actual malice, it seems.

But someone at the party recorded the chant; eventually, UMW’s Feminists United on Campus found out about it and made sure university administrators were informed. This led to an investigation, and eventually, the end of the rugby team. The location of the party was said to be a “rugby house”—even though only two members of the team actually lived there—and so the entire team had to pay the price.

First of all, the chanting, as ugly as it might have been, is perfectly legal under the first amendment. Not only was it merely speech, it took place off campus in a private residence, where the college has limited jurisdiction.

Second, what kind of justice is it for the college to punish all the members of the rugby team when only a few even attended the party? Even if it had to right to do so (which I question), punishing innocent third parties is beyond Stalinistic.

Survey shows Obamacare reduced worker hours

9:59 am

Finding out what’s in it: A survey of businesses has found that employers have reduced employee work hours significantly to avoid Obamacare.

A new survey by the Society of Human Resource Management released Tuesday found about 14 percent of businesses have reduced part-time hours and another 6 percent plan to do so. Employers are reducing hours to avoid Obamacare’s employer mandate, which requires companies to provide health insurance to all workers that work 30 or more hours a week. In addition, 5 percent of companies already reduced or plan to reduce the total number of employees.

Believe me, this is only the start. Essentially, Obamacare makes it difficult if not impossible to make a profit.

Republicans criticize Obama administration for program attacking legal businesses

9:45 am

Fascists: At House hearings yesterday Republican congressmen attacked the FDIC for creating a program that encouraged banks to cease any dealings with businesses the Obama administration happened to dislike.

Rep. Sean Duffy (R-Wis.) called on a top banking regulator to fire top employees or step down himself after certain businesses saw their accounts shuttered as part of a government program known as “Operation Choke Point.” Banking regulators have since walked back guidance that was interpreted by some as calling for banks to halt operations with entire types of businesses, but GOP lawmakers say regulators that pushed that notion still need to be held accountable. “I fear that activists at the Department of Justice and [Federal Deposit Insurance Corporation] are abusing their power and authority,” said Duffy. “They’re weaponizing government to meet their ideological beliefs.”

Martin Gruenberg, chairman of the Federal Deposit Insurance Corporation, told lawmakers Tuesday that bank examiners had misinterpreted regulatory guidance to suggest that entire categories of businesses should be barred from traditional banking services. He said earlier guidance outlining high-risk areas had been “misunderstood,” leading examiners to believe that banks should not be providing services to certain types of businesses, like payday lenders and firearms dealers. [emphasis mine]

The FDIC simply decided that certain legal businesses, specifically businesses liberals in the Obama administration were strongly hostile to, should be barred from access to banks. They weren’t illegal. They simply were disliked by liberals. The result was that many of these businesses were forced to shut down.

This quote best illustrates who was and continues to be willing to use the power of government to attack legal businesses they happen to dislike:

But Duffy accused Gruenberg of “slow walking” the matter, having failed to punish FDIC employees that pushed banks to cut services with certain industries. He went so far as to suggest that if Gruenberg did not punish those employees, he should step down as chief regulator. “I don’t think you want to hold them accountable,” said Duffy. “If you can’t go after the problem in the FDIC…you have no place as the chairman.”

For their part, Democrats largely defended the FDIC as attempting to properly implement policy and protect the banking sector.

So, the Democrats think it’s a good idea. Interestingly, Democrats took an almost identical position in regards to the IRS harassment of conservatives. To me, it seems kind of fascist. But who am I to say?
