We won’t release our contributors because the adminstration will then harass them

Is this how a government in a free society functions? The Chamber of Commerce won’t release its contributors because they fear the administration will harass and threaten them. And they have experience to back that fear up. Key quote:

What this administration wants is a list of who the companies are who are contributors, and we saw last year . . .when we very publicly ran ads against the Patients Protections and Affordable Care Act . . . there was an attempt to try and find out who were the corporations that were contributing to that effort. When some of those corporate names were divulged, not by us, by others, what did they receive? They received protests, they received threats, they were intimidated, they were harassed, they had to hire additional security, they were recipients of a host of proxies leveled at those companies that had nothing to do with the purpose of those companies. So we know what the purpose here is. It’s to harass and intimidate. [emphasis mine]

That the White House and President Obama are right now willing to accuse their opponents of all manner of evils (taking money from foreign governments) without any evidence is further evidence that there are reasons to fear them.

APS responds to Harold Lewis’s resignation letter

The American Physical Society has responded to Harold Lewis’s resignation letter.

It appears from their response that they are feeling some pressure about their past position, which stated “The evidence is incontrovertible: Global warming is occurring.” Compare that with what they say now, in their response to Lewis:

APS continues to recognize that climate models are far from adequate, and the extent of global warming and climatic disruptions produced by sustained increases in atmospheric carbon loading remain uncertain.

How nice. A science organization recognizing the uncertainty of science!

Obama signs the NASA authorization bill

Obama signed the NASA authorization bill today.

Update and bumped: This Spaceflight Now article includes this quote from Senator Bill Nelson (D-Florida):

“What is in this bill is $11.5 billion over the next six years, anticipated, even though it’s a three-year authorization, for development and testing of a heavy lift rocket. Now if we can’t develop a new rocket for $11.5 billion, building on a lot of the technologies that were already developed in spending $9 billion (on the Constellation program’s Ares rockets), if we can’t do it for that, then we ought to question whether or not we can build a rocket.”

Based on NASA’s track record in trying to build a replacement to the shuttle, I remain very skeptical indeed whether NASA can build this rocket. I do hope, however, that my skepticism is proven wrong.

Note also that the funding for this authorization bill is as yet not appropriated. Plans to do so during the lame duck session of Congress after the elections remain fraught with problems.

Asteroids of note

At today’s press conference at the 42nd meeting of the AAS Division for Planetary Sciences, the topic was asteroids, including one which holds the possibility of hitting the Earth.

  • 65 Cybele has been found to have water ice and organic molecules on its surface, the second such asteroid so found. Key quote from the abstract:

    We conclude that 65 Cybele is covered by fine anhydrous silicate grains, with a small amount of water-ice and complex organic solids. This is similar to comets where non-equilibrium phases coexist, e.g. water-ice and anhydrous silicates; thus we conclude that this is a very primitive object.

    According to Humberto Campins of the University of Central Florida, this combination of water and organics could become hospitable to life should some form of energy be added, such as an impact to the asteroid.

  • The origin of the asteroid Phaethon, cause of the Geminids meteor shower, has been traced to the Pallas family of asteroids, a family created by the debris thrown out during a crater impact on the large asteroid Pallas. Campins also noted that this proves Phaethon is an asteroid and not a comet, a question that astronomers had been debating beforehand. Read the abstract here.
  • Asteroid 1999 RQ36, which has a 1 in a 1000 chance hitting the Earth in 2182 and is also the prime target of a proposed NASA sample return mission, has now been determined to be a member of the Polana family of asteroids. This makes 1999 RQ36 a very primitive asteroid from the very beginnings of the solar system. Moreover, this suggests that the Polana family could be the “most important” source of many near Earth asteroids. The abstract can be found here.

A Tea Party in Maryland

Last night I attended the most recent meeting of the Maryland Society of Patriots, a tea party group that was founded back in 2009. Attendance was pretty typical, with about fifty people filling the meeting room of the local library in Burtonsville, Maryland. As usual, Sam Hale, the founder of the group, had garnered a range of candidates to speak to us, including Eric Wargotz, the Republican candidate for the Senator, running against Barbara Mikulski (D-Maryland).

Eric Wargotz speaking at MSOP meeting

For Wargotz, the questions got a bit heated at one point, as one member of the audience wanted to know his commitment to defending the Constitution.

What makes this group significant is that the majority of its members come from very Democratic districts. Yet, not only has attendance been high at almost every meeting, the membership has including a wide range of ordinary people, most of whom have never done politicial activitism in their lives.

The basic ingredients of life might exist in Titan’s atmosphere

Big news! In a simulation of the upper atmosphere of Titan at about 600 miles altitude, scientists have discovered the basic ingredients of life are quickly synthesized when exposed to the kind of hard radiation found there. Key quote from the press release, issued today at the 42nd meeting of the AAS Division for Planetary Sciences:

The molecules discovered include the five nucleotide bases used by life on Earth (cytosine, adenine, thymine, guanine and uracil) and the two smallest amino acids, glycine and alanine.

For those who don’t remember their high school biology, these nucleotides are the building blocks of DNA.

The abstract of the scientist’s work can be found here.

What the scientists did was recreate the basic ingredients of Titan’s upper atmosphere, comprised of nitrogen, methane and carbon monoxide. Cassini data has shown that within this atmosphere are very large molecules, as yet unidentified.

The scientists then bathed their recreation in the kind of intense radiation expected at that altitude, and amazingly produced the complex organic molecules that are basic to life. Moreover, the experiment was the first to produce these complex molecules without the presence of water, something that scientists have previously thought was required. These results suggest that in addition to forming in the oceans, life could also form in the upper atmospheres of planets.

This result also suggests strongly that it is incredibly easy to produce the basic building blocks of life, almost anywhere in the universe where organic molecules are present.

White House arbitrarily gives healthcare law waivers to some companies

The law for some but not for others: Threatened with a firestorm of protest just prior to the election because a number of large corporations were going to drop millions from healthcare coverage because of the new Obamacare regulations, the White House today arbitrarily waived for one year those provisions for 30 large companies.

This action raises three obvious points:

  • If the healthcare law was so wonderful, why is the White House suspending its inception?
  • Why should these companies get a break, and not others? In fact, if I was the owner of a company that did not get a waiver, I would sue.
  • This once again proves false the claim by Obama that the law would force no one to lose their healthcare plan. To me, the words “You lie!” come quickly to mind.

Ed Morrissey at hotair.com makes some additional good points about this absurd situation.

Geert Wilder’s words make Muslims uncomfortable

How sad. The harsh words that Dutch politician Geert Wilder has for Islam (now facing prison for saying those words) is making Muslims in the Netherlands feel unsafe. Key quote:

“My family and I no longer feel safe in the Netherlands because Mr. Wilders is continually making hateful remarks about Islamic Dutch people,” said one complaint read out by the judge.

Gee. What about the more than 16,000 violent attacks committed by Islamic terrorists since September 11, 2001, leaving tens of thousands of people dead or maimed? How does this violence make these Dutch Muslims feel?

The October 2010 sunspot graph

Yesterday NOAA’s Space Weather Prediction Center published its October monthly graph, showing the sun’s developing sunspot cycle in comparison with the consensis prediction made by the solar science community in May 2009.

October Sunspot graph

Sunspot activity in September clearly jumped, though it still remains far below predictions. Prepare for the weakest solar maximum since the 1810s!

Note also that today the Sun is blank, with no sunspots, the first time this has happened since August. At that time I speculated that this might “be the last time the Sun will be blank for years as it continues to ramp up to its next solar maximum.” Obviously not. The question now is whether today will be the finale in blankness for this minimum.

Murder for the sake of climate idealogy

Bumped. Scroll down to see the update.

This video has been making the rounds on the web. Though I warn you that is somewhat graphic, it is essential that you watch it.

When I first saw this about a week ago, I didn’t quite know what to make of it. It was so vile and offensive I could not believe that it was legitimate. It obviously wants to pay some homage to Monty Python, but even Monty Python never went this far. How could anyone possibly think that killing small children in the name of environmentalism was in any way funny? And how could anyone ever believe that this video would persuade anyone to go along with the 1010 environmental campaign? If anything, the video does an excellent job of discrediting this organization and everyone involved with it.

Thus, despite what some bloggers were saying, I held back commenting, just to make sure the video was real and not a terrible prank meant to sabotage.

There is now no reason to hold back. Late last week, the 1010 organization itself issued an apology, admitting that this video was their handiwork. Before I continue, I think it is worthwhile for you to also read their apology, in all its venal glory. In many ways, it condemns them and their allies far more than the video did:

WISE telescope moves into final phase of mission

Having run out hydrogen coolant for its infrared cameras and with only a few more months of usable life, the Wide-Field Infrared Survey Explorer (WISE) has shifted its work from deep space astronomy to completing its last sweep of the solar system in a search for asteroids and comets.

Update: At a press conference going on right now at the 42nd meeting of the AAS Division for Planetary Sciences, WISE scientists note that the mission extension will continue for one month. If that month is successful, the mission will continue until the end of January 2011 in order to complete its solar system sweep. After this the spacecraft will be put in hibernation, available for future work.

Summary of solar system results so far:

  • 33,576 asteroids discovered of which 120 were Near Earth Asteroids.
  • 19 new comets.

The wind-blown dunes of Mars

The HiRise Camera on Mars Reconnaissance Orbiter has released some wonderful new pictures, showing what are called barchan dunes on Mars.

Barchans are crescent-shaped, with the horns of the crescents pointing downwind. One barchan is visible in the upper part of the image, with the Southeast (lower right) horns longer than the other. This trend, along with the position of the steep face of the dune on the South side, indicates that the predominant winds which formed the dunes came from the North.

There are a lot more great images on the websites above.

The layoffs at NASA

More layoffs yesterday at NASA, this time at the Marshall Space Flight Center. Also, this report gives a good overview of all the layoffs so far.

One question: The authorization bill that passed Congress on Wednesday night specifically required NASA to continue construction of a heavy-lift vehicle, quite similar in concept to Constellation. Why then is NASA management laying off all these Constellation workers? Granted, the authorization did not provide Constellation with as much money as previously budgeted, but the layoffs seem greater than necessary at this time, considering the budget differences. Also, the lack of a final budget from Congress might require these layoffs to occur temporarily, pending a new budget, but NASA is not making it clear that this is the case. Instead, they are letting a lot of people go without giving them any guidance about NASA’s future plans.

If the Obama administration was serious about fulfilling Congress’s legal requirement to build a heavy-lift vehicle (as deputy administration Lori Garver said they were on Thursday), I would have expected them to be more forthcoming to these NASA employees, if only to encourage them to remain available for rehiring, for at least a short time. That they have not is very telling.

Do not expect this heavy-lift vehicle to be built.

Watch out for those toxic paper clips!

The bureaucracy marches on! The Consumer Product Safety Commission wants the manufacturers of kids’ science kits to test the paper clips in those kits for lead and other toxic chemicals, even if the paper clips were purchased in an ordinary office supply store. Key quote

“It is crazy that the Hands-On Science Partnership needs to be concerned about doing lead tests on products purchased at an office supply store and then packaged into a science teaching kit for use with children,” Commissioner Nancy Nord wrote on her blog. “Even crazier is the fact that if a teacher buys the same paper clip at the same store and uses it for the same science teaching project, it’s okay.”

To me, this quote is even more disturbing:

Commissioners insist the regulations will not ban science kits and would be applied on a case-by-case basis. [emphasis mine]

In other words, the regulation will not be applied objectively, but subjective, at the whim of the regulators. Every product of every manufacturer will have to get the Commission’s approval before it can be sold.

If that isn’t a mandate for mischief, I don’t know what is.

The state of the Sun, September 30, 2010

Time to update the state of the Sun, as seen by satellite data (the last update was in July). The graph below, posted today by Physikalisch- Meteorologisches Observatorium Davos (PMOD), shows the variation in the Sun’s Total Solar Irradiance since 1978. I have added a blue horizontal line to show that even now, two years after the Sun reached the lowest point in its most recent solar minimum, it has still not brightened enough to equal the lowest point in the two previous minimums. (Note that if we included the minimum from 1976, the Sun would still be below that as well.)

solar cycle as of Sept 30, 2010

Once again, the evidence is building that the Sun might be heading towards the weakest maximum seen to two centuries. And when that happened, things got very cold on Earth.

This NASA bill is nothing more than pork

A sampling of headlines today, describing the passage last night in the House of the NASA authorization bill:

Unfortunately, none of these headlines are correct. All of them are examples of what I call “press release journalism”, where the press writes its stories based on what elected officials and public relations people tell them, rather than what’s in the bill itself.

Though the bill that passed last night does authorize significant additional funds for the subsidized development of new private rockets, it unfortunately does not send NASA on a “new path” or “new policy.”

First and foremost, the plan very specifically requires NASA to build a spacecraft and launch capability very similar to what was being built under Constellation. To quote:

It is the policy of the United States that NASA develop a Space Launch System as a follow-on to the Space Shuttle that can access cis-lunar space and the regions of space beyond low-Earth orbit in order to enable the United States to participate in global efforts to access and develop this increasingly strategic region.

This system is to have a launch capability of no less than 130 tons, which would exceed the Saturn V and is about what was planned for Ares V.

Also:

The Administrator shall continue the development of a multi-purpose crew vehicle to be available as soon as practicable, and no later than for use with the Space Launch System. The vehicle shall continue to advance development of the human safety features, designs, and systems in the Orion project.

This essentially means that Orion, as designed under Constellation, will go on.

Thus, the only real changes to Constellation the bill provides are less money, a faster timetable (finished by the end of 2016) and the freedom to pick a new name for the system, so as to not embarass the current administration with a Bush space rocket.

Of course, NASA has the freedom to redesign Constellation, but given the short time schedule and limited budgets, I wonder if that will be possible. (There are those who think this is a victory for the Direct approach, whereby the new launch system is almost entirely based on the shuttle system, but even that concept is probably not doable, given the money and time frame.)

Thus, has anything at NASA actually changed? I don’t think so. In the end, what we are going to get from this new plan is the same failures we’ve gotten from NASA in its repeated efforts over the last twenty-five years to build a shuttle follow-on. To quote a column I wrote for USAToday back in 2004:

  • The National Aerospace Plane was proposed by President Reagan in 1986 during his State of the Union address. This cutting-edge technology, Reagan proclaimed, would “by the end of the decade take off from Dulles Airport, accelerate up to 25 times the speed of sound, attaining low-Earth orbit, or fly to Tokyo within two hours.” After spending $1.7 billion, and building nothing, the program was canceled in 1992.
  • The X-33 was announced with much fanfare by Vice President Al Gore on July 4, 1996. The program was going to produce a single-stage-to-orbit reusable spacecraft. “This is the craft that can carry America’s dreams aloft and launch our nation into a sparkling new century,” Gore enthused. After five years and $1.2 billion, the X-33 was canceled when cracks were found in the spacecraft’s experimental fuel tanks.
  • During the same years as the X-33, NASA pursued the X-34, a smaller two-stage reusable rocket launched from a belly of a L-1011 jet, and the X-38, a reusable lifeboat for the International Space Station. After four years, more than $1 billion but little hardware production, both were scrubbed. [Note that the X-37 did come back to life under the auspices of the Air Force, who saw its value if NASA did not.]
  • In 2000, even as the previous projects were being put to the torch, NASA came up with another program, the Space Launch Initiative. For two years, the agency spent $800 million drawing blueprints for a plethora of proposed shuttle replacements. Nothing was built. In 2002, the Space Launch Initiative was scrapped like the rest.

In every case, NASA came up with plans that could not be built for the money available. Now, Congress has ordered NASA to build an updated Saturn V rocket, practically overnight and without sufficient funds. And it has asked this to be done by an administration that is uninterested in doing it, and has even shown a willingness to sabotage this project, when it can.

The result? I do expect NASA to spend all the money that Congress is giving them, passing it out to various aerospace companies, as it has done for the last few decades. Whether anything will get accomplished with all that spending, however, is very doubtful.

In other words, the bill passed last night is nothing more than the worst form of pork. At least with most pork projects, a new school or a better road system is built. Here, the taxpayer will spend a lot of money, and get very little for it.

The one glimmer of hope is the money authorized to subsidize the development of new private space rockets. Unfortunately, the bill requires NASA to strictly supervise the construction of these new rockets, to make sure they meet NASA’s safety standards and government rules. Such supervision cannot encourage the kind of innovation and creativity necessary to produce new rockets cheaply and efficiently.

Fortunately, the increasing demand for new and inexpensive launch services is going to counter this governmental interference. SpaceX’s amazing success with its Falcon rockets is evidence of this increased demand. So is the fact that Boeing has decided to dive into this market with its own manned spaceship. With increased demand comes increased profit, which — far more than government subsidizes — will pay for the new rockets.

Still, on the government side I suspect the end result of NASA’s new commercial development program will once again be a lot of money wasted. The new rockets will get built, but the American taxpayer is going to get screwed in the process.

Personally, if I had my druthers I would get the U.S. government entirely out of the civilian rocket building business. Let the private companies finance and build their rockets themselves (as SpaceX did with the Falcon 1), and when completed, let NASA then buy the services. The less say the government has in the design and construction of these rockets, the better.

Unfortunately, this fantasy is not going to happen. Instead, I expect the American space program to limp along for the next decade or so, dependent on the Russians (and eventually the Chinese) to get its astronauts to its own space station.

How sad.

First planet discovered that might harbor life!

Big news! Scientists have discovered the first rocky terrestrial planet orbiting its sun at a distance where life as we know it could form. The planet itself has a mass three to four times Earth, so no matter what, conditions on its surface would be very different than here. Nonetheless, this is a major discovery, and is only the first of many. Key quote:

The discovery suggests habitable planets must be common, with 10 to 20 per cent of red dwarfs and sun-like stars boasting them, the team says. That’s because Gliese 581 is one of just nine stars out to its distance that have been searched with high enough precision to reveal a planet in the habitable zone.

Hoyer says Americans are “conflicted”

At a press briefing today my congressman, Steny Hoyer, said that he thinks Americans are “conflicted”, have “a lot of angst and anxiousness”, and are “not sure” which party will move the country forward. Steny is partly right about the first two points, but quite wrong about the third, considering his party’s dismal poll numbers.

I also suspect that Steny has a lot of his own angst and anxiousness, considering the momentum his opponent, Charles Lollar, is building.

Only one step short of tyranny

Obama is asking the court for the right to assassinate American citizens, without due process, and in total secret. Key quote:

Both the Bush and Obama administrations have repeatedly insisted that their secret conduct is legal but nonetheless urge courts not to even rule on its legality. But what’s most notable here is that one of the arguments the Obama DOJ raises to demand dismissal of this lawsuit is “state secrets”: in other words, not only does the President have the right to sentence Americans to death with no due process or charges of any kind, but his decisions as to who will be killed and why he wants them dead are “state secrets,” and thus no court may adjudicate their legality. [emphasis in original]

The Bush administration was wrong when it tried to imprison an American citizen without trial. The Obama administration is even more wrong now to claim it has the right to kill an American citizen without trial. Such behavior is unconscionable.

A November wipe-out

This article suggests that the Republican victory in November is going to be far greater than any polls have indicated. Key quote:

Only about 160 of the Democrats’ 239 Congressional Districts are even remotely considered to be in play. But that playbook is badly out of date. The Republican message has raced far ahead of the GOP campaign and put a lot of new seats in play. We just have to work these districts to win them.

In fact, there are no polls to analyze in most of these 160 districts. Nobody considered them in play enough to poll them. We just don’t know how vulnerable these extra incumbents are. But, given the surprising vulnerability of the first eighty seats, we believe that a substantial number of these formerly invincible Congressmen can be ousted. [emphasis mine]

I strongly suspect that my home district, the 5th Congressional district of Maryland, is one of these 160 unknown districts. My congressman, House Majority Leader Steny Hoyer, is running against Republican Charles Lollar. For years this district has been considered safe for Steny. No more.

Lollar, a black conservative with Tea Party connections, has run an aggressive campaign, raised lots of money, and has been unafraid of taking the race into the hardcore Democratic areas near Washington. His signs are up everyone, only a week after clinching the nomination in the primary.

Come November 2, I think that the results from this district will be a stunning upset. I also think these results will only be one example among many others.

Full disclosure notice: In all my life, I had never given money to any political candidate. I considered such contributions a waste of my money. This year, however, I broke that string. Soon after the healthcare bill passed Congress (under Steny Hoyer’s leadership), I contributed $200 to Charles Lollar’s campaign. Not only do I believe this contribution will not be a waste of money, I think the fact that I did it is another indication that the results of this coming election will be very surprising.

The crumbling cliffs of Mars

Among the new images posted last week by the HiRise camera on Mars Reconnaissance Orbiter is a picture showing the layered and looping ridgelines within Galle Crater. A close-up of these ridgelines revealed the precarious nature of those crumbling cliff tops.

Below is a low resolution version of the image, with a high resolution cropped inset below that, showing a close-up of the most interesting looking area. In the inset you can see that the top of the cliff has separated away. It almost looks as if several large pieces are about to break off. You can also see that the top of the cliff to the north is made up of hanging rocks that appear to almost float in the air. They too look as if they are about to break off.

What makes this even more intriguing is that there are no boulder piles at the bottom of any cliff. All we can see on the valley floor is a pattern of polygonal fractures, possibly “due to ground ice, or regional tectonic stresses.” If large pieces of these ridge lines are breaking off periodically, as they surely appear to be doing, where has the debris gone?

A scientist’s ten commandments

Published today on the astro-ph website, this preprint by Ignacio Ferrín of the Center for Fundamental Physics at the University of the Andes, Merida, Venezuala, is probably the shortest paper I have ever seen. I think that Dr. Ferrin will forgive me if I reprint it here in its entirety:

1. Go to your laboratory or your instrument without any pre-conceived ideas. Just register what you saw faithfully.

2. Report promptly and scientifically. Check your numbers twice before submitting.

3. Forget about predictions. They are maybe wrong.

4. Do not try to conform or find agreement with others. You may be the first to be observing a new phenomenon and you may risk missing credit for the discovery.

5. Criticism must be scientific, respectful, constructive, positive, and unbiased. Otherwise it must be done privately.

6. If you want to be respected, respect others first. Do not use insulting or humiliating words when referring to others. It is not in accord with scientific ethics.

7. Do not cheat. Cheating in science is silly. When others repeat your experiment or observation, they will find that you were wrong.

8. If you do not know or have made a mistake, admit it immediately. You may say, “I do not know but I will find out.” or “I will correct it immediately.” No scientist knows the answer to everything. By admitting it you are being honest about your knowledge and your abilities.

9. Do not appropriate or ignore other people’s work or results. Always give credit to others, however small their contribution may have been. Do not do unto others what you would not like to be done unto you.

10. Do not stray from scientific ethics.

It seems that some scientists in the climate field (Phil Jones of East Anglia University and Michael Mann of Pennsylvania State University are two that come to mind immediately) would benefit by reading and following these rules.

Now it’s “global cooling”!

So now that the “global warming” narrative is beginning to fall flat (sorry John Holdren, but I refuse to play your game and call it “global climate disruption”), what do the elite apparachiks worldwide decide to do? They get together in a private meeting in Spain in June to discuss the future threat from global cooling.

What was that? Did I hear you right? Did you say “global cooling?”

Yup. Key quote from the meeting announcement:

The 58th Bilderberg Meeting will be held in Sitges, Spain 3 – 6 June 2010. The Conference will deal mainly with Financial Reform, Security, Cyber Technology, Energy, Pakistan, Afghanistan, World Food Problem, Global Cooling, Social Networking, Medical Science, EU-US relations. Approximately 130 participants will attend of whom about two-thirds come from Europe and the balance from North America. About one-third is from government and politics, and two-thirds are from finance, industry, labor, education, and communications. The meeting is private in order to encourage frank and open discussion. [emphasis mine]

If it’s not one thing, it’s another. The goal has never been to save the Earth, but to grab power. Now that the public is questioning the reality of the global warming meme, these blowhards have to come up with some other crisis they can use to maintain their positions of power and control. And if it isn’t getting hotter, maybe it’s getting cooler? Never mind the facts or the science, which remains confused and complex. All they want is some justification, no matter how unjustified, for telling everyone else how to live their lives.

One more thought: How much do you want to bet that a good majority of the participants (the full list) flew in on private jets?

James Delingpole of the Telegraph uncovered this little tidbit, and has some blunt but very true words to say about it.

Birthplace of the Sun?

In a preprint [pdf] posted today on the astro-ph website, astronomers outline the discovery of a star more like a twin of the Sun than any previously discovered. The star is located in the galactic star cluster M67, 3000 light years away. The similarity is so close that the scientists even speculate that the Sun itself might have formed in this same cluster, 4.5 billion years ago. Key quote from paper:

The similarity of the age and overall composition of the Sun with the corresponding data of M67, and in particular the agreement of the detailed chemical composition of the Sun with that of M67-1194, could suggest that the Sun has formed in this very cluster. According to the numerical simulations by Hurley et al. (2005) the cluster has lost more than 80% of its stars by tidal interaction with the Galaxy, in particular when passing the Galactic plane, and the Sun might be one of those. We note that the orbit of the cluster encloses, within its apocentre and pericentre, the solar orbit. However, the cluster has an orbit extending to much higher Galactic latitudes, presently it is close to its vertical apex at z = 0.41 kpc (Davenport & Sandquist 2010), while the Sun does not reach beyond z = 80 pc (Innanen, Patrick & Duley 1978). Thus, in order for this hypothesis of an M67 origin of the Sun to be valid, it must have been dispersed from the cluster into an orbit precisely in the plane of the Galactic disk, which seems improbable.

The last sentences above refer to the different orbital inclinations of the galactic orbits of both the Sun and M67. M67’s orbital inclination is far steeper. While M67 is presently about 1350 light years (410 parsecs) above the galactic plane, the Sun’s orbit never takes it more than 261 light years above the plane.

One more point of interest: M67 is a well known object to amateur astronomers, located in the constellation Cancer.

The moons of Saturn

The Cassini spacecraft orbiting Saturn continues to send back a wealth of data, and some gob-smacking wonderful images. Below are two of the more recent examples. The first is not a computer-generated graphic: it shows the small moon Helene (21 miles across) during a fly-by on March 3, 2010, with Saturn’s atmosphere providing the background. The second captures Saturn’s two largest moons, with the smaller Rhea crossing in front of the larger Titan.

First tests of beer in zero gravity

Who says space exploration is dead? Sometime in November researchers will conduct the first zero gravity tests of the world’s first beer to be certified for drinking in space. The tests will take place during suborbital flights of what is commonly known as the Vomit Comet. Key quote:

Sampling the beer during weightless parabolas, the flight researcher will record both qualitative data on beverage taste and drinkability and biometric data on body temperature, heart rate, and blood alcohol content.

Federal spending is out of control and NASA’s gonna get what it wants?

You think NASA’s going get money this year or next? Or ever? In one graph (see below), this article shows how completely out of control federal spending has become, beginning in 2007, with no end in sight. Key quote:

Until this skyrocketing spending growth is arrested and reversed, we suspect that government spending has become disconnected from the ability of any American household to support it.
