New Shepard aced its landing test

8:36 pm

The competition heats up: According to an email sent out by Jeff Bezos, the recent New Shepard capsule landing test, with one parachute disabled, was a complete success.

Besides the three parachutes, New Shepard is slowed in its descent by a retrorocket that fires just before the capsule hits the ground. Bezos’ email also provided pictures of the “crushable ring” on the bottom of the capsule, which can help decelerate the craft if it hits the ground too fast (acting sort of like the bumper on a car). “Even with one chute out, the crushable barely crushed,” wrote Bezos, who is also founder and CEO of Amazon.com.

“When new, the crushable is about 5.5 inches [14 centimeters] high and can crush down to less than 1 inch [0.4 cm] high, providing a constant deceleration force as it crushes. After the mission, the crushable was still over 5 inches [12.7 cm] high along nearly the entire circumference of the ring,” Bezos wrote.

No word on when the next test flight will take place.

No 6207 A Study in Steel

6:01 pm

An evening pause: A fascinating and well-filmed documentary from 1935 describing how a British company then built locomotives. Note the lack of construction helmets, gloves, or safety glasses. Note also the number of workers involved. Today most of this work is automated, making it more precise and efficient. Then, however, they did not yet have such technology, and instead found ways to build very sophisticated machines using the skills of ordinary humans.

Hat tip Edward Thelen.

Half of TSA employees cited for misconduct

3:19 pm

Does this make you feel safer? Almost half of all TSA employees have been cited for misconduct, and the citations have increased by almost 30 percent since 2013.

Of the total allegations filed, 90.8 percent were against TSA officers, while 4.8 percent were filed against managers or administrators. Of the areas of misconduct, “Attendance & Leave” sees the highest number of offenders, while “Failure to Follow Instructions,” “Screening & Security,” “Neglect of Duty,” and “Disruptive Behavior” round out the top five.

It also appears that the TSA has been reducing the sanctions it has been giving out for this bad behavior.

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.

Satellite hit by space junk, still operational

2:00 pm

A private Earth-observation satellite, WorldView-2, was either hit by space junk or had some internal failure that produced “8 debris pieces” in its vicinity.

The Joint Space Operations Center, which is the Defense Department’s nerve center for space operations and tracks space objects from Vandenberg Air Force Base in California, tweeted July 19 that it had identified a debris-causing event related DigitalGlobe’s WorldView-2 satellite.

The amazing thing about this is that the satellite is still functional, and to prove it the company has already released an image produced after the event.

Nearby exoplanets have Earthlike atmospheres

10:58 am

Worlds without end: New data from Hubble suggests that two rocky exoplanets only 40 light years away have atmospheres more similar to Earth’s than to that of gas giants.

Specifically, they discovered that the exoplanets TRAPPIST-1b and TRAPPIST-1c, approximately 40 light-years away, are unlikely to have puffy, hydrogen-dominated atmospheres usually found on gaseous worlds. “The lack of a smothering hydrogen-helium envelope increases the chances for habitability on these planets,” said team member Nikole Lewis of the Space Telescope Science Institute (STScI) in Baltimore, Maryland. “If they had a significant hydrogen-helium envelope, there is no chance that either one of them could potentially support life because the dense atmosphere would act like a greenhouse.”

The actual make-up of these atmospheres remains unknown. Also, the central star, a red dwarf, is estimated to be about a half billion years old. Both the star’s make-up — red dwarfs are not as rich in elements as a G-type sun — and age do not provide much margin for the development of life.

Nonetheless, the new data increases again the likelihood that we will eventually find habitable worlds orbiting other stars, and we will find them in large numbers.

EPA’s gasoline efficiency tests are garbage

9:07 am

Our government in action: The tests the EPA uses to establish the fuel efficiency of cars are unreliable, and likely provide no valid information at all about the fuel efficiency of the cars tested.

The law requiring cars to meet these fuel efficiency tests was written in the 1970s, and specifically sets standards based on the technology then. Worse,

[T]he EPA doesn’t know exactly how its CAFE testing correlates with actual results, because it has never done a comprehensive study of real-world fuel economy. Nor does anyone else. The best available data comes from consumers who report it to the DOT—hardly a scientific sampling.

Other than that, everything is fine. Companies are forced to spend billions on this regulation, the costs of which they immediately pass on to consumers, all based on fantasy and a badly-written law. Gee, I’m sure glad we never tried this with healthcare!

Trump Treasury Secretary to be former Clinton donor and Goldman Sachs banker?

8:52 am

According to one Trump fund-raiser, should Donald Trump win the presidency he plans to nominate for his Treasury Secretary a former Clinton donor and Goldman Sachs banker.

[Steve] Mnuchin, who is a former donor to Hillary Clinton, spent 17 years with Goldman Sachs, where his father also had been a prominent executive. He later worked with investment groups affiliated with George Soros, including as chairman of controversial mortgage lender OneWest Bank Group (which would later be acquired by CIT Group). He also has spent time as both an art dealer and film producer.

Heh. I seem to remember how Ted Cruz was attacked because his wife worked for Goldman Sachs. Trump was going to save us from the big bankers!

I myself am not really bothered by this man’s connections with Goldman Sachs. What worries me is that Mnuchin previously supported Hillary Clinton and also has ties to the very leftwing money-man George Soros. Thus, this story once again underlines the need for voters to elect as many conservatives to Congress as possible, in order to limit the influence of Trump’s liberal friends.

International space efforts to double in next decade

8:14 am

The new colonial movement: According to a new industry analysis, the number of countries with active space efforts will double to almost fifty in the next decade.

By 2025, we estimate that the number of emerging space programs will increase to 47 countries around the world. This includes 23 newcomers who will have committed their first investment in space between 2016 and 2025. Over 130 satellites are forecast to be launched in the next 10 years, nearly double that of the last decade. The total value of these satellites should more than double at nearly $12 billion, versus more than $5 billion during 2006-2015.

The new efforts are not confined to the traditional space programs, but also include nations that will be purchasing services from others to build satellites for them.

A glacier on Mars

10:25 pm

A glacier on Mars

Cool image time! The image on the right, cropped and reduced in resolution, is a Mars Reconnaissance Orbiter picture taken on March 28, 2016 of a glacial flow coming down off of mountains in Mars’ northern mid-latitudes. The mountains are to the south and beyond the bottom right. The flow is to the northwest. The full image can be found here. As noted on the image site,

These flow-like structures were previously called “lobate debris aprons,” but the Shallow Radar (SHARAD) instrument on [Mars Reconnaissance Orbiter] has shown that they are actually debris-covered flows of ice, or glaciers. There is no evidence for present-day flow of these glaciers, so they appear to be remnants of past climates.

Need I say it? This is water, on Mars, and in abundance. Think that this might be good real estate when those first settlers arrive?

Trump will ask Congress to ease the firing of government workers

7:31 pm

Good if true: According to New Jersey governor Chris Christie, who is in charge of Donald Trump’s transition team, should he win the presidency he will ask Congress to pass laws making it easier from him to fire government workers.

Trump’s transition advisers fear that Obama may convert these appointees to civil servants, who have more job security than officials who have been politically appointed. This would allow officials to keep their jobs in a new, possibly Republican, administration, Christie said. “It’s called burrowing,” Christie said. “You take them from the political appointee side into the civil service side, in order to try to set up … roadblocks for your successor, kind of like when all the Clinton people took all the Ws off the keyboard when George Bush was coming into the White House.”

Originally these laws were passed to reduce the spoils system, whereby new presidents got to hand out lots of jobs to friends once elected. Now, these laws merely act to prevent elected officials from having any supervisory oversight over the employees they manage.

The article also noted that the Trump campaign is beginning to assemble a list of government workers they want to fire should they win. This is also encouraging, considering the overall incompetence we’ve seen in the federal government these past few years. (I would especially like to see the entire management of the National Park Service fired for the part they played in helping Obama during the government shutdown.) It is time for a purge. If Trump follows through with this, it will be a very positive thing.

Expect a lot of squealing however from the usual suspects in Washington. The key will be whether Trump will have the courage to follow through despite those squeals.

Franky Zapata demonstrating his Flyboard Air

6:01 pm

An evening pause: Hat tip t-dub, who wrote that the Flyboard Air “is a real product developed by Franky Zapata. It’s a jet powered board that reminds me of what the Green Goblin used in Spiderman. This video was done in Monaco during the Formula 1 race this year. His company is called Zapata Racing and he has developed a jet pack, water hover board, and those fire hose things people use over water which is a hydraulic Flyboard I believe. If they only had this stuff back in the 70’s when I was growing up.” T-dub also added, “The Flyboard can go up to 10,000 feet, fly at 98 MPH, and has a duration of almost ten minutes depending on use. They have also set a Guinness record with the device.”

My thought: Once again, life imitates art.

Health insurance rates in California to rise

1:46 pm

Finding out what’s in it: Health insurance rates on the Obamacare exchange in California will rise 13% next year.

Large increases on Obamacare exchanges have been par for the course throughout the country this year, which is not really a surprise for anyone who was willing to read more than one sentence of a plethora of predictions made by conservatives in 2010 before Obamacare was passed. They predicted then, as this article notes is now happening, that

Fewer people are signing up through the exchanges than anticipated, and they’re using more health care services than anticipated. That’s left insurers with fewer customers to share the overall cost.

Obviously, according to Obama and Clinton and the entire Democratic Party, the solution to this failed government health program is an even bigger government health program! Won’t that just be peachy-keen!

Japanese military satellite damaged during shipping

8:28 am

Japan’s troubled space effort suffered a bad setback when a Japanese military communications satellite was damaged in shipment to its launch site in French Guiana.

The launch of Japan’s first dedicated military communications satellite will be delayed by two years after a mishap with a blue tarpaulin damaged sensitive antennas during transportation to Europe’s Spaceport in French Guiana, two government sources told Reuters. The mishap has set back plans by Japan’s military to unify its fractured and overburdened communications network, and could hinder efforts to reinforce defenses in the East China Sea as Chinese military activity in the region escalates.

North Korea fires three more missiles

9:51 pm

Does this make you feel safer? North Korea fired three ballistic missiles early Tuesday,

North Korea fired three ballistic missiles early on Tuesday which flew between 500 and 600 kms (300 and 360 miles) into the sea off its east coast, South Korea’s military said, the latest in a series of provocative moves by the isolated country.

The U.S. military said it detected launches of what it believed were two Scud missiles and one Rodong, a home-grown missile based on Soviet-era Scud technology. North Korea has fired both types numerous times in recent years, an indication that unlike recent launches that were seen as efforts by the North to improve its missile capability, Tuesday’s were meant as a show of force.

I am sure the Obama administration is monitoring this closely!

BLM demands removal of police float from gay parade

5:27 pm

Bigots: Black Lives Matter is demanding the removal of a police float during a homosexual pride march in Vancouver.

BLM are making this demand for one reason: They are bigots, and to their bigoted view of life, all cops must be racists, even those who, with good will, want to get together to build a float and want to march in a gay pride parade.

I should add that in general, I find gay pride parades bigoted in their own way, as they also celebrate group rights rather than individual rights. All you have to do to understand what I mean is to imagine this being a White Pride or a Heterosexual Pride march, and you will immediately see what I mean. Such marches would be considered quite offensive. Yet, they really are no different than a gay pride march.

New rocket company raising investment capital

4:44 pm

The competition heats up: Two former employees of SpaceX and Blue Origin have teamed up to start their own rocket company, aimed at using 3D printing technology to build rockets “with zero human labor.”

The funding rounds are described in two documents filed in May and this month with the Securities and Exchange Commission. The first filing reports that $1.1 million in equity was sold to investors. The second filing serves as a new notice of $8.4 million in equity sold, out of a $9.6 million offering.

The filings indicate that Relativity Space is based in Seattle, but in response to an email inquiry, the company declined to say anything further about its location, its business plan or its investors. “We are entirely in stealth mode and will comment more when we are ready,” the company said.

New companies come and go, but the fact that the guys in charge of this come from these two companies, and have already raised significant investment capital, suggests attention should be paid.

Reused Dragon cargo capsule to ISS within a year

4:05 pm

The competition heats up: SpaceX hopes to launch a previously flown Dragon capsule to ISS sometime with the next year.

This fall, SpaceX plans to refly one of its landed Falcon 9 rockets for the first time — and a Dragon capsule should make history by launching on a repeat ISS resupply mission shortly thereafter, a NASA official and a SpaceX representative said during a postlaunch news conference Monday. “I think we’re looking at SpaceX-11,” said Joel Montalbano, NASA’s deputy manager of ISS utilization, referring to the 11th resupply mission the company will fly with Dragon and the Falcon 9. (Monday’s launch kicked off SpaceX-9.)

I had been wondering when SpaceX would try to reuse a Dragon, and had assumed the reason it hadn’t happened yet was partly because of NASA reluctance combined with the delays connected with the launch failure last year. Either way, it appears that NASA is now on board and that the company is beginning to gear up for that first reflight.

SpaceX seeks two more pads for returning 1st stages

3:58 pm

The competition heats up: SpaceX is asking for permission to establish two more landing pads so that it will have the capability of landing three first stages all within minutes of each other.

“SpaceX expects to fly Falcon Heavy for the first time later this year,” the company said in a statement responding to questions. “We are also seeking regulatory approval to build two additional landing pads at Cape Canaveral Air Force Station. We hope to recover all three Falcon Heavy rockets, though initially we may attempt drone ship landings” at sea.

This news suggests two things: 1. The first Falcon Heavy launch is definitely coming soon. 2. They are going to try to return all three 1st stages during that first launch.

100 Kepler exoplanet candidates confirmed

12:13 pm

Worlds without end: Astronomers have confirmed another 100 of Kepler’s more than 3,000 candidate exoplanets.

One of the most interesting set of planets discovered in this study is a system of four potentially rocky planets, between 20 and 50 percent larger than Earth, orbiting a star less than half the size and with less light output than the Sun. Their orbital periods range from five-and-a-half to 24 days, and two of them may experience radiation levels from their star comparable to those on Earth.

Despite their tight orbits—closer than Mercury’s orbit around the sun—the possibility that life could arise on a planet around such a star cannot be ruled out, according to Crossfield.

Because the host star of this as well as many of these other confirmed exoplanets are red dwarf stars, the possibility of life is reduced because the star and its system is likely to have a less rich mix of elements compared to our yellow G-type Sun.

New climate model works better, but doesn’t!

9:57 am

New climate model
Image from Junk Science. I indicated the pause

The uncertainty of science: Scientists have developed a new computer climate model that does a better job of predicting the actual climate, until you get to the pause in warming during the past 18 years. The graph on the right, from the paper, shows the model’s prediction compared to the raw data. The two line up perfectly, until around 1998, when the pause or hiatus in global warming began. From that point, the model fails.

I especially like this quote from the press release, made by one of the paper’s two authors:

“Most of the difference between the raw data and new estimates is found during the recent 18 years since 1998,” said Xie. “Because of the hiatus, the raw data underestimate the greenhouse warming.” [emphasis mine]

Note how he reverses things. For him, the raw data is wrong, as it underestimates their perfect model of human-caused greenhouse warming. In reality, it is their model that has failed, as it fails to predict the pause in warming, showing that it must be missing important factors that are influencing the climate. Or as physicist Richard Feynmann so cogently put it,

“It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.”

Note also that this research paper, released today, recognizes the pause, which shows again that the claims by some scientists that the pause did not exist have not been convincing to other climate scientists. This in turn once again illustrates the overall uncertainty of this field of science.

The rings of Saturn

The rings of Saturn

Cool image time! The picture on right, cropped by me to show here, was taken by Cassini on April 2, 2016. You can see the moons Dione (on left) and Epimetheus (on right) above the rings. The full image can be seen here.

I am sure there is a lot of important science contained within this image. I post it here however not because of any scientific reason but entirely because it is simply damn spectacular. More than a decade after Cassini arrived at Saturn, every new picture of the planet’s giant ring system still seems incredibly unbelievable.

The universe is an amazing place, isn’t it?

SpaceX chooses recovered first stage to reuse

4:31 pm

The competition heats up: SpaceX has chosen as the first Falcon 9 first stage to reuse the one that was the first to land successfully on a barge on April 8.

Though they have not announced the mission it will fly, I strongly suspect it will be one of the two SES communications satellites scheduled to launch in the fall. SES has already said they want to buy a launch using a re-used first stage, and the two SES satellites scheduled for the fall have some redundancy between them.

Getting and Installing Linux – Part 4

6:01 am

The Software Manager

by James Stephens

A computer is nothing more than a toy unless it has the tools you need to get your work done, and Linux has a great set of tools. Most distributions come loaded with the tools most people use every day, a full office suite, graphics and media packages and so on. If you want more, a world of software awaits at your fingertips via the Software Manager. Think of it as the app store for your distribution, with tens of thousands of official titles vetted and available for download, most free of charge. No longer are you left to the wilds of the Internet to find what you need.

Most Linux Software is functionally equivalent to that of Apple or Windows. Most open source titles are ported to all platforms including Linux. So if you use an open source title such as Audacity or VLC media player, just type its name into the Linux Software Manager search bar and you will find it. For propitiatory titles such as Photoshop just define what it does, image manipulation for example, and the Software Manager will suggest Linux equivalents like GIMP or KRITA. In addition Photoshop and some other Windows software run great on Linux using WINE – the Windows compatibility layer. More about that later.
