The words of NASA’s chief: “NASA is not going to the Moon with a human as a primary project probably in my lifetime.”

He’s right. Instead, others will do it. And the ones who do it from the United States, privately financed for profit, will do it quickly, efficiently, and often, three things NASA has not been able to do at all since the 1960s.

Doctors driven to bankruptcy

Doctors driven to bankruptcy.

What is amazing about this article about the recent spike in doctors filing for bankruptcy is how it somehow never mentions Obamacare at all. The closest the author comes is a mention of “changing regulations.” How informative!

If the author was a good journalist, which he isn’t, it should have been self evident that the advent and effects of Obamacare has to be included in this story, if only to give it the proper context.

New data from Curiosity has further confirmed that the atmosphere of Mars was once much thicker, and that the remaining atmosphere is still dynamic.

New data from Curiosity has further confirmed that the atmosphere of Mars was once much thicker, and that the remaining atmosphere is still dynamic.

The two most interesting bits of data is that the temperature has been steadily climbing in Gale Crater, and that the humidity has shown significant shifts, depending on the rover’s location as it has traveled through the crater.

NASA has indicated that the first manned launch using a commercial space carrier has slipped by a year.

NASA has now indicated that the first manned launch using a commercial space carrier has slipped by a year.

The reasons are as yet unclear, though it is suspected that the main cause is the decision by the Obama administration to cut the funds of this program under sequestration. As Clark Lindsey notes, however, there is no reason that some of these private companies won’t go forward and fly other passengers on their spaceships, ahead of the NASA flights. Specifically, SpaceX and its Dragon capsule should easily be ready to go well ahead of 2017, and will likely be earning enough cash from its commercial launches to pay for development even if the NASA subsidies get delayed.

The coming Obamacare chaos

10:13 am

The coming Obamacare chaos.

The article is a very detailed summary of the many problems caused by Obamacare, from increased unemployment to loss of healthcare insurance to higher premiums to higher debt. Everyone should read it. However, the most important question is laid out in the very first paragraph:

The biggest political problem faced by so-called “liberals” and so-called “progressives” in President Obama’s second term is how to prevent voters from holding them politically responsible as the public comes to realize how badly they were lied to during the first Obama term to win passage of Obamacare.

It is going to be the number one priority of all Democratic politicians and their allies in the mainstream press to somehow find a way to blame Republicans for Obamacare. The question will be whether they will succeed.

The location of the volcanoes on Titan are not where scientists had expected them to be.

The uncertainty of science: The location of the volcanoes on Titan are not where scientists had expected them to be.

As Io moves closer to Jupiter, the planet’s powerful gravity pulls hard on the moon, deforming it. This force decreases as Io retreats, and the moon bounces back. This cycle of flexing creates friction in Io’s interior, which in turn generates enormous amounts of volcano-driving tidal heat. Common sense suggests that Io’s volcanoes would be located above the spots with the most dramatic internal heating. But Hamilton and his colleagues found that the volcanoes are significantly farther to the east than expected.

Many of the news headlines, including the article above, have trumpeted how the volcanoes on Io are in the wrong place. (See also this article.) Not. The theories were wrong, not the volcanoes. Nature does what it wants to do. It is our job to figure out why.

Using Hubble astronomers have confirmed that it was a yellow supergiant star that was the progenitor for the nearest supernovae in decades that occurred in 2011.

Using Hubble astronomers have confirmed that it was a yellow supergiant star that was the progenitor for the nearest supernovae in decades, that occurred in 2011 in the Whirlpool Galaxy.

The uncertainty of science: As I noted in 2011 when the yellow supergiant was first detected in pre-explosion images. no theory at that time had ever proposed this kind of star as a supernova progenitor. The discovery has thus required the theorists to come up with new theories.

The scientists who attempted to re-invent Michael Mann’s hockey stick global warming graph and were caught fudging their data have admitted their data is worthless

12:17 am

The scientists who attempted to re-invent Michael Mann’s hockey stick global warming graph and were caught fudging their data have essentially admitted that their data is worthless.

This is what they say in a FAQ they have added to their paper:

Q: What do paleotemperature reconstructions show about the temperature of the last 100 years?

A: Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the 20th century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used. Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions. [emphasis mine]

They are basically admitting that the data used to create the temperature rise of their hockey stick during the past 100 years is unreliable and therefore useless for scientific purposes. Which raises the question: Why did they publish it in the first place? See especially this analysis of this paper and the press’s reaction to it by climate scientists Roger Pielke.

North Korea says it has authorized plans for nuclear strikes against the United States.

2:59 pm

Bad: North Korea says it has authorized plans for a nuclear strike against the United States.

But, while Pyongyang has successfully carried out test nuclear detonations, most experts think it is not yet capable of mounting a device on a ballistic missile capable of striking US bases or territory. Mounting tension in the region could however trigger incidents on the tense and heavily-militarised border between North and South Korea. There was no immediate American reaction to the North’s latest statement, but US Defense Secretary Chuck Hagel said Pyongyang represented a “real and clear danger” to the United States and to its allies South Korea and Japan. [emphasis mine]

Right now North Korea almost certainly cannot hit the U.S. with an ICBM. However, South Korea and Japan are very very very exposed.

“The SLS program should be canceled now to free up approximately $10 billion programmed for this decade.”

“The SLS program should be canceled now to free up approximately $10 billion programmed for this decade.”

I’m both glad and not surprised that some heavy hitters are beginning to say this. As I noted last year, as the commercial space program begins to show success the politics will increasingly favor it over the very expensive and not very productive NASA-built Space Launch System.

Be prepared for SLS to steadily lose political support in the coming years.

The Alpha Magnetic Spectrometer on ISS has detected a surplus of positrons, anti-matter electrons, that physicists believe are caused by the existence of dark matter.

The Alpha Magnetic Spectrometer on ISS has detected a surplus of positrons, anti-matter electrons, that physicists believe are caused by the existence of dark matter.

The lead scientist of the experiment also emphasized that dark matter is not the only possible explanation, and that “The detailed interpretation of our data probably will have many theories.”
