Part of the gas cloud being ripped apart by the supermassive black hole at the center of the Milky Way have already swung past the black hole.

3:54 pm

Part of a gas cloud, being ripped apart by the super massive black hole at the center of the Milky Way, has already swung past the black hole.

“The ionised gas at the head of the cloud is now stretched over more than 150 light-hours (about 160 billion kilometres) at the pericentre of the orbit around the black hole, with the closest approach being about 25 light-hours (or a bit more than 25 billion kilometres)”, explains Stefan Gillessen from MPE, who led the observing team. “The pericentre approach however is not a singular event but rather a process that will be stretching over a period of at least one year.”

The black hole, dubbed Sagittarius A* (pronounced A-star), is more than 4 billion times the mass of our Sun, but emits very little energy for its size. (Most super massive black holes emit energy as they swallow the mass around them.) Astronomers are hoping that they will see some action when it eats this cloud sometime next year.

The IRS now claims that the government official who willfully accessed confidential tax records illegally was not an IRS employee.

O goody: The IRS now claims that the government official who willfully accessed confidential tax records illegally was not an IRS employee.

How does this make anything better? Instead of an IRS official rummaging through confidential tax records for political purposes, they apparently let others in government do it directly.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

SpaceX has renegotiated its lease with the city of McGregor, Texas, in order to begin testing the Falcon Heavy rocket.

8:59 am

The competition heats up: SpaceX has renegotiated its lease with the city of McGregor, Texas, in order to begin testing the Falcon Heavy rocket.

What I found stunning about this article is this quote:

The Falcon Heavy will have commercial, civil and national security applications, Ra said, adding that customers will pay $81 million to $135 million per launch, depending on the weight of the payload and the rocket’s destination. That is about twice the price of a Falcon 9 launch.

These prices for the Falcon Heavy are actually comparable or cheaper than that charged by most other rocket companies for geosynchronous launches. If SpaceX succeeds in doing this — launching Falcon Heavy at these prices — they will certainly open deep space to private enterprise. And even if their prices end up being twice this, those prices will still be anywhere from one fourth to less than a tenth of what it will cost NASA to launch its SLS rocket.

Which should make us all wonder: Why is anyone in Congress still voting to fund SLS?

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

A survey shows that three quarters of all small businesses still plan to fire workers and cut hours in 2014 to avoid Obamacare, even though the Obama administration says it will not enforce the law unitl 2015.

A survey shows that three quarters of all small businesses still plan to fire workers and cut hours in 2014 to avoid Obamacare, even though the Obama administration says it will not enforce the law unitl 2015.

This makes sense. The law is still the law, even if the Obama administration won’t enforce it. If a business doesn’t cut the hours or the number of its workers to avoid the Obamacare mandates, but then does not provide those mandates, its employees can then sue the business and likely win.

The result: Expect the economy to tank next year as this turkey of a law takes hold and chokes the life out of American enterprise.

The Sun has a maximum and no one notices

10:43 am

On July 8 NOAA released its monthly update of the Sun’s sunspot cycle, covering the period of June 2013. As I do every month, this graph is posted below, with annotations to give it context.

After a brief period of renewed but weak activity during the last three months, the Sun’s sunspot production has once again plunged, dropping back to the levels generally seen for most of 2012.

As predicted by some solar scientists, the Sun seems to have produced a double-peaked maximum, though the second peak appears at this time to have been remarkably wimpy and brief. It is still possible, however, that this second peak is not over and that we might see another burst of renewed activity in the next month or so, based on the Sun’s past behavior during the ending stages of the previous solar maximum in 2001 and 2002. Nonetheless, from all appearances it looks like the Sun has shot its load and is in the process of winding down from a solar maximum peak that occurred back late 2011.

What is especially fascinating about this is that when that peak occurred in 2011, no one noticed!

“We have had an enormous amount of death threats.”

8:50 am

Modern civility: “We have had an enormous amount of death threats.”

I think this story sums up the entire George Zimmerman case. An ordinary citizen kills a black man in self-defense — clearly proven in court — and because of this he and his family are now under constant fear for their lives.

In other words, the violent, racist thugs in this case are all on the Trayvon Martin side of the coin.

SpaceX has successfully completed a full duration test firing of 9 upgraded Merlin engines.

8:33 am

The competition heats up: SpaceX has successfully completed a full duration test firing of 9 upgraded Merlin engines.

The full mission duration firing of the next generation Falcon 9 booster was completed on Sunday. The booster’s nine Merlin 1D engines fired for approximately three minutes, simulating what the booster may experience in flight before stage separation.

With this success, I suspect they are finally ready to begin their commercial launches. The first is presently scheduled for September 5.

Treasury admitted today that the IRS tax records of several political candidates and campaign donors were illegally disclosed to unnamed government officials.

8:43 pm

The law is such an inconvenient thing: The Obama Treasury Department admitted today that the IRS tax records of several political candidates and campaign donors were illegally disclosed to unnamed government officials.

[O]f the four instances in which tax records were improperly accessed, three cases were determined to be “inadvertent.” “In the fourth case, we presented evidence of a willful unauthorized access to the Department of Justice, but the case was declined for prosecution,” Mr. George wrote. Of the three cases that the inspector general called “inadvertent” disclosures, Mr. George said his office referred one to Justice with a recommendation that no prosecution be brought. He said Justice officials agreed with his office’s assessment. No reason was given for Justice’s rejections of prosecutions.

I wonder why the Obama Justice Department declined to prosecute that fourth case, which was “willful” and thus very illegal.

Doing the Grand Canyon Right

2:50 pm

The Tonto Plateau

The one thing about the Grand Canyon that attracts hikers is its intimidating nature. People feel challenged by its large size and depth, and want to prove to themselves that they can do it.

The irony of this to me is that it is that intimidating nature that generally causes most people the most problems. People worry about the climb out. They worry about the heat. They worry about the lack of water. And they worry about vastness around them.

All of these things — the climb, the heat, the lack of water, and the vastness — must be dealt with. Each has caused the death of many visitors. Each could kill you if you are not prepared. In fact, one or all of these factors are probably the primary causes behind all of the approximately 300 rescues that occur each year at the Grand Canyon.

Yet, none of these factors is actually the biggest obstacle for most people trying to climb in and out of the Canyon. Instead, it is the worry about these things that causes people the most difficulties.

The competition heats up: Orbital Sciences has issued an update on its Antares launch schedule, with the launch window for the Cygnus demonstration mission to ISS now set for September 14-19.

They announced this on July 10, but I am only now catching up. The launch could happen sooner, if there are delays to the launch of NASA’s LADEE moon probe. Right now the two launches are coordinated to have LADEE launch first.

The competition heats up: Sierra Nevada has completed its first tow tests of its Dream Chaser engineering test vehicle, now officially named “Eagle.”

These tests were merely to check out the craft’s landing systems, with it being pulled along the runway at 10 to 20 mph. Faster tests, followed by actual drop tests, are to follow.

The article has some great information about Dream Chaser itself.

At the rim 2

3:42 pm

We have returned from inside the Grand Canyon. We hiked out on Tuesday, doing the climb up in what is for us record time, arriving at the rim at 12:30 pm after 7 hours of hiking. We were down at Phantom Ranch for two full days and three nights, doing some really spectacular day hikes each day. I will post some further details, with pictures, once I get home.

We are still touring about here in northern Arizona and will be until Sunday. Right now I am sitting in the patio of the motel at Grand Canyon Caverns, about two hours west of the national park. This morning we drove down to the Colorado on the Hualapai Reservation, using the only road on the south rim that reaches the river. This weekend I will be participating in a long term cave dig project here at this somewhat famous commercial cave. The dig has been going on for years in cooperation with the cave’s owners. This will be the first time that I will contribute to the project.

At the rim

8:02 pm

The Grand Canyon from our motel room

After a 5.5 hour drive we arrived at the south rim of the Grand Canyon and checked into our hotel. You can see the view from the window on the right. Not very spectacular, but then, you don’t spend much time in a hotel room on trips like this.

Tomorrow we take the shuttle bus to the North Rim, where will spend another night in the lodge there. On Saturday, we hike down on North Bright Angel trail, and will stay in a cabin at Phantom Ranch for the next three nights, doing day hikes from the bottom of the canyon on Sunday and Monday. We will hike then up on Tuesday, coming up Bright Angel trail to the south rim, completing our first rim to rim hike. Once we check out of our hotel tomorrow, we will be out of contact with the internet until we return to the south rim. I hope the world doesn’t fall apart in the interim.

This will be Diane’s third trip to the bottom, and my fifth. I can’t express how happy I am to be back. This is truly one of the grandest spots on Earth.

The Russian investigation into the crash of their Proton rocket on Tuesday now includes a criminal prosecutor.

8:48 am

The Russian investigation into the crash of their Proton rocket on Tuesday now includes a criminal prosecutor.

“The investigative department of the Russian Investigative Committee at the Baikonur complex has opened a criminal case on this incident over evidence of a crime, put forward in the Russian Criminal Code Article 216 Part 1. The Baikonur prosecutor’s office is overseeing the investigation,” the statement said.

There is also another story from this news service claiming that the crash occurred because the rocket launched a half second early, confusing its computer systems.
