New smallsat company plans 200 satellite constellation

8:45 am

The competition heats up: A new smallsat satellite company, Sky and Space Global, is planning to launch a 200 nanosat communications constellation for less than $160 million.

More important, they have funded and built the first three, which they will launch in 2017:

The company, located in the U.K., Israel and Australia, has fully funded the first three satellites to precede an initial constellation of 200 nanosatellites. Coined the “Three Diamonds,” the nanosatellites are scheduled to launch as a rideshare aboard a Polar Satellite Launch Vehicle (PSLV) from the Indian Space Research Organization (ISRO) in the second quarter of 2017.

The pilot satellites are to determine the final characteristics of Sky and Space Global’s operational satellites, which are scheduled to begin launching in 2018 via Virgin Galactic’s LauncherOne. Sky and Space Global’s goal is to field a constellation that will eventually become global for low cost telecommunications services such as voice, instant messaging and data forwarding.

What this story illustrates is that the smallsat market is about to become a reality, and in doing so it will shake up the entire geosynchronous communications satellite industry, much as SpaceX has shook up the launch industry. As I’ve noted earlier, these new smallsats suggest that the space industry is splitting, with unmanned Earth-orbit satellites going small and manned capabilities staying large.

ULA interns launch record-breaking model rocket

4:49 pm

The competition heats up: A team of ULA interns, working in their spare time, have successfully launched the largest model rocket every built.

On Sunday (July 24), ULA launched the 50-foot-tall (15.24 meters) Future Heavy rocket out of Fort Carson Army Post, breaking the record for “the largest sport rocket launched anywhere in the world,” according to a statement from ULA. The Future Heavy is also notable because it was built entirely by company interns and their mentors. “We like [our interns] to have a very realistic experience,” ULA President and CEO Tory Bruno told Space.com at the Space Symposium meeting in Colorado Springs, Colorado, last April.

Calling it a “model rocket” really isn’t fair. The thing is big, and really ranks up there with many of the suborbital rockets NASA used to routinely fly out of Wallops Island. That ULA has provided support for this effort again suggests that the leadership of Bruno is reshaping the company into a much more innovative and competitive company.

The Sun is blank again

2:01 pm

More signs that we are easing down to solar minimum: After a period of two weeks of sunspots, the Sun has once again gone blank.

It takes the Sun’s about four weeks to rotate and complete one “day”. What has essentially happened is that right now one face of the Sun is blank while the other face has sunspots. For two weeks, from the last week in June to the first week in July, the blank face was turned towards the Earth. Then the face with sunspots rotated into view for two weeks, and now the blank face has rotated back to face us.

Though new sunspots can always form on either face, I expect this blank stretch to last a few days, at least.

Ceres lacks large craters

10:59 am

The uncertainty of science: Using data from Dawn, scientists have found that the solar system’s largest asteroid, Ceres (also called a dwarf planet by confused scientists), has a mysterious lack of large craters.

Marchi and colleagues modeled collisions of other bodies with Ceres since the dwarf planet formed, and predicted the number of large craters that should have been present on its surface. These models predicted Ceres should have up to 10 to 15 craters larger than 250 miles (400 kilometers) in diameter, and at least 40 craters larger than 60 miles (100 kilometers) wide. However, Dawn has shown that Ceres has only 16 craters larger than 60 miles, and none larger than 175 miles (280 kilometers) across.

They postulate two theories to explain the lack. First, Ceres might have formed far out beyond Neptune, though this theory is not favored because some models still say that even here Ceres should have large craters. Second,

One reason for the lack of large craters could be related the interior structure of Ceres. There is evidence from Dawn that the upper layers of Ceres contain ice. Because ice is less dense than rock, the topography could “relax,” or smooth out, more quickly if ice or another lower-density material, such as salt, dominates the subsurface composition. Recent analysis of the center of Ceres’ Occator Crater suggests that the salts found there could be remnants of a frozen ocean under the surface, and that liquid water could have been present in Ceres’ interior.

Past hydrothermal activity, which may have influenced the salts rising to the surface at Occator, could also have something to do with the erasure of craters. If Ceres had widespread cryovolcanic activity in the past — the eruption of volatiles such as water — these cryogenic materials also could have flowed across the surface, possibly burying pre-existing large craters. Smaller impacts would have then created new craters on the resurfaced area.

This theory doesn’t really work that well either, because it fails to explain why only the big craters got erased.

Two different kinds of boos

9:52 am

The American election process can be messy and entertaining, frightening and exhilarating, confusing and educational. In the past week we have had one great example of this during the nominating conventions of our two main political parties. In both cases, the convention-going party attendees have broken out in loud boos, loudly attacking people on the podium for their positions. Such behavior is not what you would expect from the modern conventions, which for several decades have been nothing more than staged propaganda events designed to sell their candidates to the American public. One doesn’t usually boo during such staged events.

First we had at the Republican convention the response to Ted Cruz’s speech, where when he refused to endorse Donald Trump he was almost literally driven from the stage by boos from the audience.

Then, yesterday we had Bernie Sanders supporters overwhelm the Democratic convention with boos, first during an appearance of former Democratic chairwoman Debbie Wasserman Schultz and then during the convention’s opening prayer.

It is important to understand the difference between these boos, as they are a strong marker of what will happen in November. In the case of the Republicans, the booing was in support of the Republican candidate, hostile to the implied opposition to Donald Trump by Ted Cruz. In the case of the Democrats, the booing was in opposition to the Democrat candidate, hostile to Hillary Clinton’s nomination and the perception that the Democratic Party stole the nomination from Bernie Sanders.

I have always believed that Hillary Clinton was the worst presidential candidate I have seen in my lifetime. It seems to me that this difference illustrates this fact once again. Sadly for me, the Republicans have wasted this opportunity and picked a liberal Democrat as their candidate, losing the best opportunity since 1980 to put an honest and principled conservative into office.

All I can do now is hope that Donald Trump will surprise me and be far more conservative than I expect, when he becomes President in January.

Hackers devise method to take over wireless keyboards/mouses

9:21 am

Your modern wireless computer is not safe: Hackers have devised an attack that is capable of not only recording the keystrokes and mouse actions of wireless devices, it can also take over the computer, and it can do it from hundreds of feet away.

On Tuesday Bastille’s research team revealed a new set of wireless keyboard attacks they’re calling Keysniffer. The technique, which they’re planning to detail at the Defcon hacker conference in two weeks, allows any hacker with a $12 radio device to intercept the connection between any of eight wireless keyboards and a computer from 250 feet away. What’s more, it gives the hacker the ability to both type keystrokes on the victim machine and silently record the target’s typing.

The keyboards’ vulnerability, according to Bastille’s chief research officer Ivan O’Sullivan, comes from the fact that they all transmit keystrokes entirely without encryption. The manufacturers’ only plan against attackers spoofing or eavesdropping on their devices’ communications is to depend on the obscurity of the radio protocols used. “We were stunned,” says O’Sullivan. “We had no expectation that in 2016 these companies would be selling keyboards with no encryption.”

In other words, if you use a wireless keyboard or mouse, your system is very vulnerable and exposed.

I find this story amusing in a sense, since my friends constantly make fun of me for not upgrading to these devises. I however see no reason to spend money on a new keyboard when the old wired one I have works fine. Now I have good reason, when I do upgrade, to avoid the wireless route.

Swedish engineer test flies human-carrying drone

9:09 am

A Swedish engineer, in his garage, has built a flying vehicle using drones and gasoline engines.

You have to see the thing to understand how insanely simple, crazy, and cool this is. For example, the whole thing is essentially nothing more than a seat surrounded by eight drones, their spinning propellers rotating only about two feet from the passenger.

But it appears to work, though the design is without doubt not quite finalized. I have embedded a video of one of his test flights below the fold. This was fortunately an unmanned flight, because about three minutes in the vehicle goes out of control and crashes.

India faces $1 billion in damages for space contract cancellation

8:52 am

An arbitration court at the Hague yesterday ruled that India faces $1 billion in damages because of its unilateral cancellation in 2011 of a satellite deal between itself and a private company.

More info here. Essentially the ruling says that India had made a legal commitment when it signed the contract, and by unilaterally cancelled it they did harm to the private company’s shareholders.

This case illustrates that, despite India’s successes in space, it is still running a government space program, with all the flaws that come with it. Paying off these damages will likely put a serious crimp in the country’s space effort in the next few years.

Rosetta says goodbye to Philae

8:35 am

The Rosetta science team has decided to shut off tomorrow the communications equipment the spacecraft uses in its continuing attempts to re-establish communications with its Philae lander.

Switching off the ESS is part of the preparations for Rosetta’s end of mission. By the end of July 2016, the spacecraft will be some 520 million km from the Sun, and will start facing a significant loss of power – about 4W per day. In order to continue scientific operations over the next two months and to maximise their return, it became necessary to start reducing the power consumed by the non-essential payload components on board.

Though until now they have never stopped trying to contact Philae, they have heard nothing since July 2015. Moreover, the recent close sweeps down to the comet’s surface have failed so far to locate the lander. Unless they are holding back the lander’s discovery for a big splash press conference, it appears that we will never known exactly where the lander touched down.

That is, we will never know. Someday, many decades in the future, some asteroid/comet mining operation will show up and find it. I hope at that time they will carefully pack it up and bring it back for humans to admire as a testament to our human ability to push the unknown. Even better, I hope they put it in the “History of Space” museum, located not on Earth but on Mars, built to educate the children of the colonists who are making possible the expansion of humanity out to the stars.

Democrats add space language to platform

9:05 am

The Democrats have added language to their party platform that expresses support for NASA and continuing its funding.

It’s only a single paragraph filled with the typical blather we see in both parties’ platforms: We support it! It’s great! It’s for the children!. The last line however gives a sense of where they’d like to focus their funding:

We will strengthen support for NASA and work in partnership with the international scientific community to launch new missions to space.

Not surprisingly, if compelled to support space the Democrats see it mostly as a vehicle for increased international cooperation.

Despite my cynical analysis above, the fact that both parties feel compelled right now to express positions supporting the exploration of space is a sign indicating where the political winds are blowing. The excitement created by SpaceX’s low prices and successful vertical first stage landings has even reached into the thick skulls of politicians from both parties. Rather than mouth the Democratic half-century-old mantra that “We should solve our problems here on Earth before spending it in space” (first pushed hard by Ted Kennedy in a speech the night before Apollo 11 was launched to the Moon), Democrats have not only apparently concluded that this won’t sell anymore, they now feel it necessary to express support for space funding.

Now, if only we can convince them to stop wasting it on SLS we might actually build a thriving and competitive space industry, capable of doing it all.

Another da Vinci discovery

8:52 am

A historian doing a detailed study of Leonardo da Vinci’s research on the nature of friction has discovered his first notes on the subject, where da Vinci outlined the laws of friction two hundred years before they were finally documented by a French scientist.

“The sketches and text show Leonardo understood the fundamentals of friction in 1493,” says Hutchings. “He knew that the force of friction acting between two sliding surfaces is proportional to the load pressing the surfaces together and that friction is independent of the apparent area of contact between the two surfaces. These are the ‘laws of friction’ that we nowadays usually credit to a French scientist, Guillaume Amontons, working 200 years later.”

It is an unfortunate thing that da Vinci lived and worked in Italy. Though this was where the Renaissance blossomed, it is also the place where some scientists at the time were persecuted for being too honest about their research. To protect himself da Vinci confined his scientific genius to his private diaries, written in a backwards script he created so that no one could easily understand what he wrote. Thus, while his brilliance as a painter was recognized in his lifetime and after, the discoveries he had made about engineering and science were lost for literally centuries.

I wonder if there are individuals, especially in the climate field, who are now experimenting with similar techniques to hide their work.

Curiosity’s way forward

11:17 pm

Panorama with balanced rock

As Curiosity moves up into the foothills of Mount Sharp the terrain is getting increasingly interesting. The image above is a panorama I have created from three Left Navigation Camera images posted here on Sunday evening. It shows what I think will be the general direction mission scientists wish to send Curiosity. (Note that the top of the leftmost mesa is not as flat as shown, as its top was cut off in the original image.)

Below is a Mars Reconnaissance Orbiter image showing Curiosity’s present position from above. I have annotated it to show the general view as shown in the above image. I have also marked on both the location of the balanced rock first photographed on July 7.

A good summary of the Wikileaks DNC emails

10:09 am

Link here. This Reddit post essential lists several dozen links to specific DNC emails at the Wikileaks site, all illustrating some pretty unsavory behavior by Democratic Party officials and politicians as well as a number of so-called journalists.

Many of these stories are simply the ordinary dirty business of politics, laid bare to see. Others though reveal the significant levels of corruption that permeate the Democratic Party, levels I think that far worse than anything one could find among the Republicans, bad as that party’s leadership happens to be.

Above all, the emails that document the close teamwork between the press and the Democratic Party are probably the most important. It is not that this is surprising. The emails merely prove it beyond a shadow of doubt. MSNBC and its head Phil Griffin especially are revealed to be nothing more than Democratic operatives, working closely with the DNC to push its agenda.

More speculations about Trump’s cabinet

8:43 pm

This article gives a nice overview of the people who it appears are being considered for positions in a Trump presidency, should he win.

Unfortunately, it does not give a lot of background about the people mentioned. Many, like Chris Christie, Jeff Sessions, Rudy Giuliani, and Newt Gingrich, are well known. Others, like businessman Donald McGahn, are unknown. Some, like Senator Bob Corker, suggested as potential Secretary of State, would be a disaster, based on his past history of getting the Iran deal approved.
Some. like Harold Hamm and Steve Mnuchin, have been described here at BtB at the links behind their names, Hamm positively and Mnuchin negatively..

There is more at the link. Read it all. This list is a start. It will require vetting to get a sense of what we can expect from a Trump administration.

Note that there is a reason I am so focused on Trump and not Clinton. Trump remains an unknown, who might be worth voting for if it appears his plans as President are reasonable, something that might still be possible, despite all the negative reports I’ve given him. Moreover, there is a chance that Trump can be positively influenced. Learning as much about him as possible increases that possibility.

Clinton however is not an unknown. She is corrupt, a liar, and an avowed socialist who believes strongly in increasing the size and power of the federal government, as does the entire political party that supports her. To deny any of this is to live with your head in the sand. She thus needs no vetting.

Getting and Installing Linux – Part 5

6:01 am

Running Windows programs on Linux:

An overview of WINE and Virtual Machine

by James Stephens

In addition to all the software available for Linux, Linux also possesses the ability to run Windows software using either WINE or in a virtual machine. This can be valuable in many ways, from running legacy software to running Windows and Linux on the same machine at the same time.

WINE is the open source implementation of CrossOver, which Apple users may already be familiar. It is essentially a translator: WINE sits between a Windows application and the Linux system, presenting what appears to be a Windows system to an application and generating Linux instructions for processing. It’s not a perfect solution, but it’s pretty good. It’s fast and efficient, requiring little more resources then the application itself, making it suitable for older machines. When properly configured, Windows applications install as if in Windows and run on Linux like any other application. The backward compatibility of WINE is actually better then that of Windows itself. So if you have beloved but outdated software you can run it again with WINE. In my case that is a Windows 3.1 controlled audio mixing console. A lot of people like to play the old Windows 95 games. For more information including a list of compatible Windows software and performance assessments go to www.winehq.org

New smallsat rocket company plans first launch in 2018

4:59 pm

The competition heats up: Vector Space Systems now plans its first test flights of its Vector 1 will begin in 2017 with the first orbital flights in 2018.

[Chief executive Jim Cantrell] said he expects to do three or four orbital launches in 2018, increasing to 12 in 2019. “We’re going to call them test launches,” he said of the planned 2018 launches, “but we have a number of people who want to buy those launches already.”

Cantrell said Vector Space Systems has signed up one customer, and is in negotiations with a second customer, both of whom he declined to name. Both customers, he said, are planning satellite constellations. “Between those two, we will have sold close to 30 launches,” he said, with those launches spread out over several years.

Vector 1 is being designed to launch very small satellites weighing generally less than 100 pounds.

Trump considers funding super-PACs to defeat Cruz and Kasich in later elections

4:48 pm

Update on the November Democratic primary: Donald Trump is considering creating two super-pacs expressly focused at destroying the political careers of Ohio Governor John Kasich and Texas Senator Ted Cruz.

During an event in Cleveland on Friday, Trump hinted at the prospect of funding an outside group against Cruz in the future.“Maybe I’ll set up a super-PAC if he decides to run,” Trump said of Cruz. Turning to his running mate Mike Pence he asked rhetorically, “Are you allowed to set up a super-PAC…if you are the president, to fight someone?”

The source close to Trump’s thinking indicated that Trump would consider forming the super-PAC whether or not he wins the presidential election in November.

This sure doesn’t sound like the actions of a Republican and conservative looking for allies within his party. Instead, it sounds like a Democrat who, having gotten the Republican nomination for President, can now stop pretending and begin the process of using his position to destroy the conservative movement in the United States in order to make it easier to impose liberal policies.

Trump’s supporters keep screaming that Cruz should have endorsed Trump for party unity. Well, the same applies to Trump — to bring the party together — only more so, since he has the nomination for president and as such is the de facto leader of the party. Moreover, while Cruz’s speech could have been more carefully worded, it nonetheless laid out the arguments for voting against Hillary Clinton and supporting all Republicans nationwide, even Trump (though unstated). Trump however is clearly doing the exact opposite, considering the investment of millions of his own money to actively work to defeat two of the party’s more conservative Republicans.

But hey, Trump can win! Who cares what he stands for!

Black Lives Matter rejects good will gesture by police

10:36 am

Hateful bigots: The Oakland Black Lives Matter group bluntly rejected an offer from the city police department for a joint barbecue to foster communications.

[T]he police were met with flat-out rejection by a spokesperson who referred to law enforcement as “pigs.”

“A BBQ is definitely not going to stop this blockade,” Karissa Lewis, a self-described “radical black farmer from East Oakland,” told local Fox affiliate KTVU. “And as a radical-black farmer from East Oakland, I eat pigs, I don’t eat with them,” she said.

But hey, this is the new standard for today’s politics: slander your opponent and foster ill will between people. It’s what we want!

Humana abandoning Obamacare

6:45 pm

Finding out what’s in it. Humana, one of the nation’s largest heathcare companies, has decided to leave almost half of its Obamacare markets next year.

Humana, one of the nation’s top health insurers, is pulling out of ObamaCare plans in all but a handful of states after a year of nearly $1 billion in losses. The company plans to exit nearly half of its Obamacare markets next year, the company announced during an earnings report Thursday. It will take part in “no more” than 11 state marketplaces, down from 19 states this year, the company said. [emphasis mine]

Remember, it was the insurance companies that lobbied the hardest for Obamacare, figuring they would clean up once the government forced everyone to buy their product. In looking at the numbers above, $1 billion in loses in one year alone, it sure seems that strategy has backfired big time on the insurance companies.

Then again, how could they have possibly known this would happen? No one anticipated this at all, except for those evil tea partiers and those racist conservatives. And who listens to them?

Cruz’s speech at the convention

11:12 am

My first reaction to Ted Cruz’s exhortation that Republican’s vote their conscience in his speech at the Republican Convention last night was distress, as I expected the response to be mostly hostile (which it was) and unnecessary, as to my mind he could have gone there and simply said that “When Donald Trump becomes the next president I will be ready and waiting in the Senate to work with him to make sure the Constitution is defended and the federal government is brought under control.” Worded in this way, Cruz would not have been endorsing Trump, but he also would have not made himself an enemy of a significant percentage of the Republican voting bloc.

However, these two articles have changed my mind:

Cruz did the right thing. As noted at the first link,

If you’re voting for Donald Trump because you think he’s the lesser of two evils; because you think Hillary is clearly worse; because you reject leftism and know Hillary will foist leftism on us and only suspect Trump might . . . then you and I are cool. I respect that position. It’s not my position — but if it’s yours, I respect it, and I respect you.

But if you’re going to knock Ted Cruz for standing up against a man who bullied his family, I don’t respect you. I don’t want you here. Feel free to leave. It may make this place smaller, but it will make it better.

The second link also noted the unhealthy nature of today’s politics, where somehow one is not allowed to take a stand on conscience because of politics. Well to hell with that. There are things worth dying for, and one’s family is surely one of them.

Trump considers fracking businessman for Energy Secretary

10:11 am

Good news if true: Reuters today reported that presidential candidate Donald Trump is considering nominating Oklahoma businessman Harold Hamm as energy secretary if he wins the election.

In addition to considering Hamm, who has also functioned as Trump’s informal energy adviser in recent months, the article also noted this:

Trump, who has yet to make any announcements about his prospective cabinet, has already surrounded himself with strong advocates of traditional energy sources like oil, gas, and coal and has promised to gut environmental regulations to boost drilling and mining if elected. He tapped U.S. Congressman Kevin Cramer of North Dakota, a climate skeptic and drilling advocate, to help draw up his campaign energy platform, and picked Indiana Governor Mike Pence, also a climate skeptic, as his running mate.

Both moves cheered the energy industry but alarmed environmental activists who say a Trump presidency would set back years of progress on issues like pollution and climate change. “Given that Hamm’s as close as we’ve got to a fracker-in-chief in this country, it would be an apropos pick for a president who thinks global warming is a hoax manufactured by the Chinese,” said leading environmental activist Bill McKibben.

I keep saying it: Should Trump win, the best way we can guarantee that he favors conservative values is if he is surrounded by conservatives. These moves suggest that that Trump is agreeable to this, though there is also possibly a bit of some crony capitalism going on here as well. While these guys will likely advocate for less environmental regulations, I also doubt that they will work to eliminate the gobs of corporate welfare the federal government presently hands out.

ULA chief says Congress deal clears path to Vulcan

9:52 am

The competition heats up: The CEO of ULA, Tory Bruno, said in an industry publication interview today that the Congressional deal that allows the company to buy 22 more Russian engines for its Atlas 5 clears the way for their eventual transition to the Vulcan rocket and an end to dependence on those Russian engines.

The article is worth a careful read, as it also provides a very detailed look at ULA’s future plans for its Atlas 5, Delta 4 Heavy, and Vulcan rockets. This paragraph was especially interesting:

The next major milestone is determining what engine will replace the [Russian] RD-180. Washington-based Blue Origin is developing the BE-4, a privately funded Liquid Oxygen (Lox) and Liquefied Natural Gas (LNG) engine capable of 550,000 pounds of thrust (lbf); and California-based Aerojet Rocketdyne is creating the AR1, a government-supported Lox/Kerosene (RP-1) engine capable of 500,000lbf. Either replacement will require two engines to match the power of the RD-180. Blue Origin claims its engine, already four years into development, will be flight qualified by 2017, while Aerojet Rocketdyne, having started its development later, says the AR1 will be flight qualified by 2019. Bruno said ULA would make its decision soon.

“Sometime close to the end of the year we are going to down-select, and then move into our Critical Design Review (CDR) and start manufacturing the rocket,” he said.

I strongly suspect they want to go with Blue Origin’s engine, because it is more powerful, farther along in development, and almost certainly less expensive. The question will be whether pressure from Congress, which favors Aerojet Rocketdyne’s engine for pork barrel reasons (Congress is funding it), will force ULA to go with it instead.

Flyboard Air company purchased

9:41 am

The company that designed the Flyboard Air jet hoverboard, featured here only two days ago in the Evening Pause, has been purchased by Implant Sciences, a company whose primary focus until now was explosive detection technology for the Homeland Security.

Implant Sciences is currently looking into the possibility of selling its explosives detection business, and the purchase of Zapata is subject to shareholder approval. Overall though, it seems pretty confident that the move could lead to big things. “We are beyond excited to have visionaries like Franky Zapata and his team on board and we are thrilled to allow for shareholders to benefit from the many breakthrough products he has already invented and the new innovations he will be unveiling in coming months and years.” said Implant Sciences president Robert Liscouski.
