The repairs to the cracks in the first Orion capsule have withstood static stress tests.
I’m so glad: The repairs to the cracks in the first Orion capsule have withstood static stress tests.
In addition to the various loads it sustained, the Orion crew module also was pressurized to simulate the effect of the vacuum in space. This simulation allowed engineers to confirm it would hold its pressurization in a vacuum and verify repairs made to superficial cracks in the vehicle’s rear bulkhead caused by previous pressure testing in November.
The November test revealed insufficient margin in an area of the bulkhead that was unable to withstand the stress of pressurization. Armed with data from that test, engineers were able to reinforce the design to ensure structural integrity and validate the fix during this week’s test. [emphasis mine]
I love how this NASA press release describes the cracking of the capsule bulkhead during the November testing, indicated in bold. “Insufficient margin”, eh?
Normally I am very forgiving when things fail during engineering tests, but for the bulkhead of this capsule to crack during these tests was actually pretty shameful, considering the decades of engineering work previously done in the building of space capsules and submarines. Things can certainly go wrong when you build something new, but I don’t see anything particularly revolutionary about Orion’s design. Lots of things might fail, but making sure the bulkhead could withstand the normal and well known stresses of spaceflight should not have been one of those things. The bulkhead failure suggests to me some sloppy engineering work took place in Orion’s initial design.

The predictions of seventy-three climate models are compared to real data and not one comes even close to reality.
The predictions of seventy-three climate models are compared to real data and not one comes even close to reality.
Remember: computer modeling is not science research. It does not tell us anything about the actual climate. It is instead theoretical work useful for trying to understand what the data actual is telling us.
Computer modeling, however, is totally useless if it doesn’t successfully mimic that actual data. Since all of these climate models fail to do this, they very clearly show that they do not understand the climate itself, and are not valid theories to explain its processes. If the scientists who created them were honest about these results, they would immediately go back to the drawing board and rewrite these models.
I unfortunately have serious doubts they will do this.

I especially like this one:
A Hispanic student group at Northwestern University instructed members of the campus community to forgo eating tacos and drinking tequila on Cinco de Mayo, so as not to offend Mexican culture. But Mexican students, who indeed wanted to spend their holiday eating tacos and drinking tequila, took offense at the assumed offense. The Hispanic student group ended up with huevo on its face.

A message to moderate Muslims.
A message to moderate Muslims.
What we need is a Muslim backlash, and we need it now. You may be a moderate, peaceful Muslim, but there’s nothing moderate or peaceful about your religion, and you know it.
The bigots who preach in your mosques, who take sustenance from your religion, are hiding behind you. And your silence is helping them to do it. If your mosque is letting anyone preach hatred and violence on its premises, you have a duty to call the police. And the police have a duty to take off their politically correct-tinted glasses to go into that mosque, without removing their shoes, and arrest that person. Anything less than this, and you’re on the wrong side.
As always, Pat Condell puts it bluntly but honestly. If Islam is being hijacked by radicals, as so many politically correct people claim, than the religion can easily be saved if the reasonable people within stand up to them. If they don’t, however, they tell us that the religion isn’t being hijacked. It is radical, and violent, and should be shunned and opposed by all reasonable people worldwide.

The technology is quite primitive, requires many hours of training, and can only move the helicopter up, down, left, or right. Nonetheless, it is one step closer to magic.

A new report from Social Security has raised its predicted unfunded liabilities over the next 75 years by one trillion dollars.
The day of reckoning looms: A new report from Social Security has raised its predicted unfunded liabilities over the next 75 years by one trillion dollars, for a total of $9.6 trillion.
According to the report, “Through the end of 2087, the combined funds [OASI and DI] have a present-value unfunded obligation of $9.6 trillion.” That is “$1.0 trillion more than the measured level of $8.6 trillion a year ago,” states the report, in reference to the data available for 2011. That $9.6 trillion shortfall equals approximately $83,894 per household based on the Census Bureau’s latest estimate that there are 114,430,000 households in the country.
The report also looks farther into the future and saw the shortfall rise to $23 trillion.

The Sun makes the scientists look good — for now!
NOAA today released its monthly update of the Sun’s sunspot cycle, covering the period of May 2013. As I have done every month for the past three years, I have posted this latest graph, with annotations to give it context, below the fold.
For the third month in a row, the Sun has shown increased sunspot activity. Though the total activity continues to remain well below all predictions, it appears that the Sun is going to produce a double-peaked maximum, as predicted by some solar scientists back in March. Be aware however that this prediction isn’t based on any real understanding of the physical processes that produce sunspots but is instead based on the fact that the Sun has sometimes done this in the past. If you asked these scientists why the Sun sometimes produces a double-peaked maximum they will wave their arms about but will really not be able to tell you.
Stratolaunch officially announced today that Orbital Sciences will build the system’s second stage rocket.
The competition heats up: Stratolaunch officially announced today that Orbital Sciences will build the system’s second stage rocket.
The rocket that Orbital will build for Stratolaunch will launch from the air, the first stage being a giant airplane which will carry that rocket aloft, much like Virgin Galactic’s WhiteKnightTwo and Orbital’s Pegasus rocket. Clark Lindsey at the same website also notes that the efforts of SpaceX (and to my mind Stratolaunch) to make the first stage reusable will likely revolutionize the rocket industry.

In related news, it appears that the IRS not only targeted conservative organizations which applied for tax exempt status, the tax agency also targeted the donors to those organizations.

Russia’s Proton rocket successfully launched a commercial satellite today.
The competition heats up: Russia’s Proton rocket today successfully launched another commercial communications satellite.
The troublesome Briz-M upper stage still has to get the satellite to its proper orbit, so stay tuned. Nonetheless, this launch, only a few weeks after their last commercial Proton launch, suggests they were serious about launching nine more commercial launches this year.
Meanwhile, we wait for SpaceX’s first commercial launch by the Falcon 9 rocket. Their launch manifest still claims there will be three such launches before the next Falcon 9/Dragon mission to ISS later this year, but two of those launches were supposed to have occurred already. The non-occurrence of the March MDA/Cassiope launch out of Vandenberg is especially puzzling, as there are few scheduling conflicts at that rarely used spaceport.
The Falcon 9 delays at this point are beginning to be worrisome, and suggest the skepticism of some about SpaceX’s ability to compete might have merit. SpaceX has got to launch a commercial satellite soon in order to quell those doubts.

In celebration of its tenth year in orbit, scientists running the Mars Express mission have released global mineral maps of Mars.
In celebration of its tenth year in orbit, scientists running the Mars Express mission have released global mineral maps of Mars. With video.
The unique atlas comprises a series of maps showing the distribution of minerals formed in water, by volcanic activity, and by weathering to create the dust that makes Mars red. They create a global context for the dominant geological processes that sculpted the planet we see today.
Take a look at the video. It is fascinating to see where these minerals concentrate.
