JPL has issued a press release “reality check” on the impact possibilities of asteroid 2011 AG5 in 2040.

“In September 2013, we have the opportunity to make additional observations of 2011 AG5 when it comes within 91 million miles (147 million kilometers) of Earth,” said Don Yeomans, manager of NASA’s Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif. “It will be an opportunity to observe this space rock and further refine its orbit. Because of the extreme rarity of an impact by a near-Earth asteroid of this size, I fully expect we will be able to significantly reduce or rule out entirely any impact probability for the foreseeable future.” Even better observations will be possible in late 2015.

In other words, we really will not know anything more about these possibilities until late next year.

ATK prepares for another test firing of its five-segment solid rocket motor.

ATK prepares for another test firing of its five-segment solid rocket motor.

The qualification campaign, led by rocket-builder ATK, will prove the solid-fueled motor is ready to help propel the Space Launch System from Earth on two test flights in 2017 and 2021.

Though obviously funded out of the Space Launch System program (SLS), there is no guarantee at this moment that ATK’s solid rocket will be used in these test flights. NASA has said that they are considering all options for picking the launch rocket.

In a sense, we are now seeing a side benefit produced by relying on independent and competing private companies to get into space. It has placed pressure on NASA and the companies building SLS to perform. Unlike in the past, when failure to produce a new rocket or spaceship meant that NASA would simply propose a new concept and start again, now failure will mean that someone else might get the work. The result: SLS might actually get built, for less money and faster.

Though I don’t see how NASA can possibly cut the costs down to compete with these private companies, their effort might succeed enough for Congress to keep the money spigots open until the rocket gets built.

Even as I say this I remain skeptical. Considering the federal budget situation, the politics of the upcoming election, and the strong possibility that private companies will successfully provide that launch capability at a tenth the cost, I expect that sometime in the next two or three years Congress will finally balk at SLS’s cost, and eliminate it.

The first industrial railgun has begun firing tests at the Naval Surface Warfare Center in Virginia.

The first industrial railgun has begun firing tests at the Naval Surface Warfare Center in Virginia. With video.

Following a series of low-energy test shots, evaluation of the launcher is now underway and will see tests conducted at 20 megajoules to 32 megajoules – one megajoule is equivalent to a 1-ton object being thrust at 100 mph (161 km/h). Test projectiles similar to those previously fired from [the] laboratory’s launcher will be fired at speeds of 4,500 to 5,600 mph (7,242 to 9,012 km/h) using electricity instead of chemical propellants.

These speeds are a only little less than one third escape velocity. Pump this technology up a bit and you could have a cheap way to get simple supplies, such as fuel, water, oxygen, into orbit. In fact, one company is even trying to do it.

The Zombie Mohammad judge defends his actions.

The Zombie Mohammad judge defends his actions.

On the first amendment:

Here’s the thing: It’s a right, it’s not a privilege, it’s a right. With rights come responsibilities. The more that people abuse our rights, the more likely that we’re going to lose them.

So in other words, it’s an abuse of free speech to criticize Mohammad, but perfectly okay to physically attack that person for that criticism.

This judge has got to go.

Astronomers have discovered a five hundred foot wide asteroid that has a 1 in 600 chance of hitting the Earth in 2040.

Astronomers have discovered a five hundred foot wide asteroid that has a 1 in 600 chance of hitting the Earth in 2040.

“2011 AG5 is the object which currently has the highest chance of impacting the Earth … in 2040. However, we have only observed it for about half an orbit, thus the confidence in these calculations is still not very high,” said Detlef Koschny of the European Space Agency’s Solar System Missions Division in Noordwijk, The Netherlands.

New evidence suggests that Stone Age hunters from Europe reached the New World ten thousand years before their Asian counterparts.

New evidence suggests that Stone Age hunters from Europe reached the New World ten thousand years before their Asian counterparts.

A remarkable series of several dozen European-style stone tools, dating back between 19,000 and 26,000 years, have been discovered at six locations along the US east coast. Three of the sites are on the Delmarva Peninsular in Maryland, discovered by archaeologist Dr Darrin Lowery of the University of Delaware. One is in Pennsylvania and another in Virginia. A sixth was discovered by scallop-dredging fishermen on the seabed 60 miles from the Virginian coast on what, in prehistoric times, would have been dry land. …

What’s more, chemical analysis carried out last year on a European-style stone knife found in Virginia back in 1971 revealed that it was made of French-originating flint.

None of this is really surprising. Once we humans became the creatures we are, it became second nature for us to spread out quickly across the globe. In the case of these first European settlers, however, they came in too small numbers, and were thus eventually overwhelmed by the later settlers coming from Asia.

The problems of making both wind and solar power practical sources of electrical power on the grid.

5:29 pm

The difficulties making both wind and solar power practical sources of electrical power on the grid.

According to the U.S. Department of Energy, when intermittent sources such as solar or wind reach about 20 percent of a region’s total energy production, balancing supply and demand becomes extremely challenging: rolling blackouts can sometimes become inevitable. The same problem exists elsewhere, notably in Germany, where a vast photovoltaic capacity has sprung up thanks to generous subsidies.

The article proposes several reasonable solutions for storing power for use when there are lulls in wind or sunlight. All, however, appear costly, and all appear to end up making fossil fuels themselves more cost effective. For example,

A pumped-hydro facility consists of two reservoirs with a substantial drop in height between them. When there is excess electricity to go around, electric pumps move water from the lower reservoir into the upper one, thereby storing energy in the form of gravitational potential energy. When wind and solar wane or simply cannot keep up with demand, operators let water flow down and through turbines, generating electricity. In compressed-air facilities, excess electricity pumps air into underground caverns, and it is later released at high pressure to turn turbines.

Pumped hydro has been used for decades to balance the load on large U.S. grids. About 2.5 percent of the electricity used by U.S. consumers has cycled through one of these plants. In Europe the amount is 4 percent and in Japan 10 percent.

Reading this, I immediately asked, why not use this technology now to help reduce the amount of fossil fuels you need to burn? Japan seems to have figured this out. Why not us?

The Astros remove a picture of a Colt revolver from their original baseball jerseys.

4:11 pm

Stupidity: The baseball Astros have been forced by league officials to remove the picture of a Colt revolver from their original baseball jerseys.

[Major League Baseball] gave the okay to the uniform, which the Astros will wear to kick off a season of throwbacks commemorating the 50th anniversary of the club. It nixed the pistol on the uniform in an era when guns are a sensitive issue, according to an Astros official.

Investigators have decided that it was sloppy bookkeeping rather than criminal activity that caused MF Global to illegally misuse and then lose more than a $1 billion of customer funds.

The fix is in: Investigators have decided that it was sloppy bookkeeping rather than criminal activity that caused MF Global to illegally misuse and then lose more than a $1 billion of customer funds.

Regulators and law enforcement officials have spoken to numerous former employees of MF Global since the firm’s demise and continue to review the hundreds of documents before they make their final conclusion. But one employee who hasn’t been interviewed by the criminal investigators is [former Democratic Governor and Senator Jon] Corzine. People close to the probe say they won’t likely depose him unless a criminal probe appears more likely.

How convenient. The man in charge, Corzine, who was also the “go-to” guy for the Obama administration on economic matters, is somehow not questioned.

A new poll show that Obamacare continues to be a major political problem for Obama.

9:37 am

Surprise, surprise! A new poll shows that Obamacare continues to be a major political problem for Obama, and Romney.

In the poll, Obama lags the two leading Republican rivals in the 12 states likely to determine the outcome of a close race in November:

  • Former Pennsylvania senator Rick Santorum tops Obama 50%-45% in the swing states. Nationwide, Santorum’s lead narrows to 49%-46%.
  • Former Massachusetts governor Mitt Romney edges Obama 48%-46% in the swing states. Nationwide, they are tied at 47% each.

Romney also has a health care problem: Among Republicans and Republican-leaning independents in the battleground states, 27% say they are less likely to support him because he signed a Massachusetts law that required residents to have coverage. Just 7% say it makes them more likely to back him.

At least Romney has made it clear he intends to repeal Obamacare, which should help him in the election should he overcome the Republican hostility to RomneyCare and become the Republican candidate. For Obama, however, there is no escape. Obamacare is his problem, and his alone, and he is likely going to go down in flames because of it more than anything else.

“Well, basically, we’re not looking to the Constitution on that aspect of it.”

6:06 pm

More video of that townhall meeting where Congresswoman Kathy Hochul (D-New York) was challenged by her constituents over Obama’s contraceptive mandate. Her answer:

Well, basically, we’re not looking to the Constitution on that aspect of it.

She essentially admits that when it comes to the Democratic Party and the Obama administration, policy will trump the Constitution every time.

At the end of the videotape, when she finds herself literally speechless and unable to respond intelligently to the questions being put to her, she says, “Clearly, more work needs to be done.” I agree. The work that needs to be done is to throw these thugs out of office.
