Orbital ATK begins assembly of first orbital repair satellite

8:49 am

Capitalism in space: Orbital ATK has begun the assembly of Mission Extension Vehicle 1, (MEV-1), designed to attach itself to commercial satellites and extend their life.

Controlled by the company’s satellite operations team, the MEV 1 uses a reliable, low-risk docking system that attaches to existing features on a customer’s satellite. The MEV-1 provides life-extending services by taking over the orbit maintenance and attitude control functions of the client’s spacecraft. The vehicle has a 15 year design life with the ability to perform numerous dockings and repositionings during its life span.

They hope to launch before the end of 2018. Meanwhile, the legal battle between Orbital ATK’s effort to build this satellite repair mission and DARPA’s effort to subsidize SSL’s own satellite repair mission continues in Congress with the introduction of two amendments favoring Orbital ATK.

Cats are liquid — if they choose to be

8:37 am

Science marches on! A new study shows that cats can be liquid, if they choose to be.

Fardin noticed that these furry pets can adapt to the shape of the container they sit in—think of a cat in a vase—similarly to what fluids such as water do. So he used the principles of rheology, the branch of physics that deals with the deformation of matter, to calculate cats’ relaxation time, or the time it takes for them to take up the space of a vase or bathroom sink.

The conclusion? Cats can be either liquid or solid, depending on the circumstances, Fardin reported in the Rheology Bulletin in 2014…. A cat in a small box will behave like a fluid, filling up all the space, but a cat in a bathtub full of water will try to minimize its contact with it and behave very much like a solid.

Anyone who has ever owned a cat will be understand this research. It isn’t that cats can be liquid that is expected, it is that cats will do what they want. If they want to be liquid, no one is going to stop them.

Because of this ground-breaking research, the scientist has won this year’s Ig Nobel Physics Prize.

Cassini’s mission ends

8:30 am

Enceladus as seen by Cassini two days before mission end

After a seven year journey and thirteen years in orbit around Saturn, Cassini’s mission ended early this morning with a dive into Saturn’s atmosphere.

The image above, cropped to show here, is actually one from a short movie, showing Enceladus setting behind the horizon of Saturn. The images were taking two days ago, but provide a fitting image for the mission’s end.

Some of the best images from the dive, including Cassini’s last image, can be found here.

While most of the press will rightly wax eloquent about the magnificence of this mission, my focus remains on what will come next. We no longer have any way to observe what is happening on Saturn. We are blind. We should not be.

ESA buys the first Ariane 6 launches

7:22 pm

The European Space Agency (ESA) has purchased the first two Ariane 6 launches to place four of its Galileo GPS satellites in orbit in the 2020-21 timeframe.

This is not a big surprise, since ESA is mandated to use Arianespace’s rockets, and the space agency is the obvious candidate for making the first commitment to this new rocket’s use.

The press release does not mention the price that Arianespace is charging for these launches, but I suspect it isn’t anywhere near as cheap as they will have to charge to truly private and commercial customers. Essentially, I am willing to bet that this contract award is a bit of crony capitalism, designed to pass some extra cash from ESA to Arianespace.

North Korea fires another missile

7:10 pm

North Korea today test fired another missile, this time sending it over Japan and into the Pacific Ocean.

South Korea’s defense ministry said it probably traveled around 2,300 miles and reached a maximum altitude of 478 miles after being launched near Pyongyang’s airport.

It was the second aggressive test-flight over the territory of the close US ally in less than a month and it followed the sixth and most powerful nuclear test by North Korea to date on September 3.

New theory for formation of main asteroid belt

11:56 am

The uncertainty of science: Using computer models, astronomers have developed a new completely different theory to explain the existence of the asteroid belt between Mars and Jupiter.

The asteroid belt (sometimes referred to as the main asteroid belt) orbits between Mars and Jupiter. It consists of asteroids and minor planets forming a disk around the sun. It also serves as a sort of dividing line between the inner rocky planets and outer gas giants. Current theory suggests that the asteroid belt was once much more heavily populated, but the gravitational pull of Jupiter flung approximately 99 percent of its former material to other parts of the solar system or beyond. Astronomers also assumed that Jupiter’s gravity prevented the material in the belt from coalescing into larger planets. In this new effort, the researchers propose a completely different explanation of the asteroid belt’s origin—suggesting that the belt started out as an empty space and was subsequently filled by material flung from the inner and outer planets.

The new theory is interesting in that it really illustrates how little we really know about the formation of our solar system. The simple fact is that either one of these theories might be the answer, even though they propose completely opposite initial conditions. We simply do not have enough information about solar system formation in general to constrain our models and determine which of these theories is right.

Until scientists have been able to study hundreds, if not thousands, of solar systems up close, these models will be nothing more than interesting exercises in computer modeling.

Hubble spots a pitch-black exoplanet

9:44 am

Astronomers using the Hubble Space Telescope have determined that an exoplanet is practically pitch black, reflecting almost no light.

NASA’s Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet’s unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere.

The oddball exoplanet, called WASP-12b, is one of a class of so-called “hot Jupiters,” gigantic, gaseous planets that orbit very close to their host star and are heated to extreme temperatures. The planet’s atmosphere is so hot that most molecules are unable to survive on the blistering day side of the planet, where the temperature is 4,600 degrees Fahrenheit. Therefore, clouds probably cannot form to reflect light back into space. Instead, incoming light penetrates deep into the planet’s atmosphere where it is absorbed by hydrogen atoms and converted to heat energy.

Because the exoplanet is tidally locked, with one side always facing its sun and the other always in nightime, the nighttime face is estimated to be about 2,000 degrees cooler, and actually shows evidence of the existence of water vapor and clouds.

It is now bad to cheer for the USA in California

9:24 am

Link here. The story is about how the principal of a local high school sent an email to the families of all students telling them that they should reconsider chanting “USA!” at sports events, as such chants might offend some.

The school’s principal sent out an email to families, Wednesday and relayed the same message to students over the school’s PA system, clarifying any confusion.

She told students and parents that sometimes “We can communicate an unintended message.” She also said USA chanting is welcome, but it may be best to do it at what she says are appropriate times, like following the national anthem or the Pledge of Allegiance. School officials worry the chants could come across as intolerant and offensive to some.

You see, to these California officials, the United States is essentially an evil and racist nation whose only past achievement was to enslave minorities. To show pride in this country is to show pride in this vision, and they want to make sure their students all know this.

What a slander and lie. To me, this position not only illustrates the utter ignorance of these school officials, but their hatred of all things American. If I had a kid in this school I would now be homeschooling them.

How not to land a rocket

9:01 am

The SpaceX blooper reel! It shows some crash footage that had not been released earlier. Also, the captions almost certainly were written by Musk himself, and if not, reek of his sense of humor, and also reveal the humbleness that he and his company bring to this effort. If you can’t laugh at yourself, you will make it hard to spot the moment when you are making a major error.

Berkeley creates police state in anticipation of conservative speaker

6:55 pm

Free speech in fascist California: In order to prevent violence against a conservative speaker, the town of Berkeley is imposing very strict security controls for tomorrow’s event.

The key security measure that I think will make the most difference are these:

UC Berkeley’s Provost Paul Alivisatos sent a recent campus-wide message detailing security plans, saying no one wearing masks or carrying weapons of any sort will be allowed on campus.

Police will block off the building where Shapiro is scheduled to speak and several other buildings hours before the event starts. Anyone entering the secure zone to pick up tickets must present a photo I.D. Nearby parking lots will be closed.

Berkeley police chief Andrew Greenwood said police will make “very strong, rapid arrests” Thursday night if any protesters have weapons or wear masks.

You want to commit violence, you won’t be able to do it anonymously, as was allowed previously.

Though it is tragic that so much of the population of California hates dissent so much that they are willing to commit violence to squelch opposing points of view, it is progress that the local government and university administration are finally acting to defend the people’s right to speak freely.

First global map of the trace water on the Moon

11:31 am

Trace water on moon

Using data collected by an American instrument on India’s Chandrayaan-1 lunar orbiter scientists have produced the first global map showing the locations and quantities of trace water on the Moon.

The map above, reduced to post here, is the result. The green areas at high latitudes show the most evidence of water, but the amounts remain very tiny, and the evidence remains somewhat uncertain.

Regardless, this map indicates that the high latitudes of the Moon will likely be the most valuable real estate for future colonists.

Cassini on final approach to Saturn

11:12 am

Engineers have confirmed that Cassini is now on its final approach to Saturn, with a scheduled dive into the gas giant set for Friday, September 15.

The mission’s final calculations predict loss of contact with the Cassini spacecraft will take place on Sept. 15 at 7:55 a.m. EDT (4:55 a.m. PDT). Cassini will enter Saturn’s atmosphere approximately one minute earlier, at an altitude of about 1,190 miles (1,915 kilometers) above the planet’s estimated cloud tops (the altitude where the air pressure is 1-bar, equivalent to sea level on Earth). During its dive into the atmosphere, the spacecraft’s speed will be approximately 70,000 miles (113,000 kilometers) per hour. The final plunge will take place on the day side of Saturn, near local noon, with the spacecraft entering the atmosphere around 10 degrees north latitude.

We will get Cassini’s last images about 90 minutes after its death.

Wasserman Schultz’s IT guy Imran Awan funnelled data to illegal secret server

10:49 am

Imran Awan, Debbie Wasserman Schultz’s IT guy who is now charged with bank fraud, was initially banned when it was discovered that he was funnelling data and emails of numerous Democratic congressmen to a secret server and to Dropbox — against House rules — and then tried to hide this fact from investigators.

Now-indicted former congressional IT aide Imran Awan allegedly routed data from numerous House Democrats to a secret server. Police grew suspicious and requested a copy of the server early this year, but they were provided with an elaborate falsified image designed to hide the massive violations. The falsified image is what ultimately triggered their ban from the House network Feb. 2, according to a senior House official with direct knowledge of the investigation.

The secret server was connected to the House Democratic Caucus, an organization chaired by then-Rep. Xavier Becerra. Police informed Becerra that the server was the subject of an investigation and requested a copy of it. Authorities considered the false image they received to be interference in a criminal investigation, the senior official said.

Data was also backed up to Dropbox in huge quantities, the official said. Congressional offices are prohibited from using Dropbox, so an unofficial account was used, meaning Awan could have still had access to the data even though he was banned from the congressional network.

Awan had access to all emails and office computer files of 45 members of Congress who are listed below. Fear among members that Awan could release embarrassing information if they cooperated with prosecutors could explain why the Democrats have refused to acknowledge the cybersecurity breach publicly or criticize the suspects.

It appears that Awan might have been blackmailing these Democrats. There is also the strong possibility, though no direct evidence has as yet been found for this, that he and his co-workers were working for foreign powers in the Islamic world.

“Taking the red pill”

10:18 am

Link here. The article gives us a hint that the oppressive, thug-like, brownshirt behavior coming from many on the left is actually backfiring, and backfiring in a big way.

The term “taking the red pill” derives from the movie “The Matrix,” the trippy sci-fi classic. Morpheus, the resistance leader played by Laurence Fishburne offers Neo, the movie’s hero played by Keanu Reeves, a choice: He can take the blue pill and remain in the repressive artificial world known as the Matrix where “you wake up in your bed and believe whatever you want to believe.” Or he can take the red pill and tumble down the “rabbit hole” where he will come to realize that everything about his life was a lie.

The left’s intensifying war on free speech has produced a surge of red pill videos. Some take Owens’ in-your-face approach. Others are meandering, hipster confessionals delivered with the wordy earnestness of characters in a Duplass brothers movie.

Read it. It provides a lot of examples of former leftists suddenly realizing that they have little in common with the modern left.

Is this happening? I suspect it is, but it is doing so very far below the radar of the mainstream press and our bankrupt intelligentsia.

Trump administration shuts down NIH anti-gun research

10:07 am

The NIH has quietly shelved all funding for gun research, most of which had been instigated under the Obama administration as a propaganda tool to promote gun control.

The article from Science is remarkable — coming from a mainstream academic source — in that it provides a fair description of the perspective of the NRA and gun-owners.

Note: Reader Kirk noted my error in originally crediting this article to Nature, when it truth it was Science that published it. Post corrected. Sorry!

An oral history of the Cassini mission to Saturn

10:00 am

Link here. Those who have read my book on the building of the Hubble Space Telescope will recognize many of the same people and political maneuvers used to get the project off the ground and funded.

Note too that the idea of Cassini was first proposed in 1982, but it didn’t actually launch until 1997. Fifteen years. While today I think such a spacecraft could go from concept to launch much faster, this timeline gives us a guide on when the next Saturn orbiter might launch. At the earliest do not expect another mission to Saturn to launch before 2025.
