Interstellar object Oumuamua tumbling chaotically

A new analysis of the data obtained when the interstellar object Oumuamua flew through the solar system in October 2016 suggests that it is tumbling in a chaotic manner, and that the surface is spotty.

Straight away, they discovered that ‘Oumuamua wasn’t spinning periodically like most of the small asteroids and bodies that we see in our solar system. Instead, it is tumbling, or spinning chaotically, and could have been for many billions of years.

While it is difficult to pinpoint the exact reason for this, it is thought that `Oumuamua impacted with another asteroid before it was fiercely thrown out of its system and into interstellar space. Dr Fraser explains: “Our modelling of this body suggests the tumbling will last for many billions of years to hundreds of billions of years before internal stresses cause it to rotate normally again.

To me, this data settles the question about whether Oumuamua is not an artificial structure. It is not. If it were, an impact that would have caused this kind of tumbling would have almost certainly destroyed it. Instead, it likely broke the original bolide up, producing many fragments, including Oumuamua and its elongated shape.

As for the object’s spottiness:

Dr Fraser explains: “Most of the surface reflects neutrally but one of its long faces has a large red region. This argues for broad compositional variations, which is unusual for such a small body.”

It is really a shame we couldn’t get a closer look before it sped away.

Back from the hunt

Gary looking out across the deseart during the javelina hunt

I got back from my javelina hunt earlier today, and am only now getting down to some business.

Sadly, we didn’t bag anything. In fact, based on the lack of gunfire for miles around, I suspect not many others did as well. It seemed the area we were hunting might have become a bit popular in the last two years, and the javelinas have moved on, or gotten smarter about hiding. No matter. I don’t give up easy. We shall try again next year, probably in a different more remote location.

Even so, the weekend was quite pleasant. Got to spend my time wandering about in some beautiful country. The image on the right shows my hunting partner (and mentor) Gary looking across one wash.

A good health check for Mars Reconnaissance Orbiter

Link here. The article outlines in good detail the spacecraft’s present condition, which is excellent despite being in space since 2005, as well as outlining the measures being taken to keep it operational into the 2020s.

This item is probably the biggest cause for concern:

For example, some HiRISE images taken in 2017 and early 2018 show slight blurring not seen earlier in the mission. The cause is under investigation. The percentage of full-resolution images with blurring peaked at 70 percent last October, at about the time when Mars was at the point in its orbit farthest from the Sun. The percentage has since declined to less than 20 percent. Even before the first blurred images were seen, observations with HiRISE commonly used a technique that covers more ground area at half the resolution. This still provides higher resolution than any other camera orbiting Mars — about 2 feet (60 centimeters) per pixel — and little blurring has appeared in the resulting images.

HiRISE is the spacecraft’s primary instrument, and its most valuable. If it goes, we will lose our best tool right now for looking in detail at the Martian surface.

Trump signs two-year budget deal

Big spending wins! The new two-year budget deal, which provides increased spending and eliminates the sequestration budget caps, has been signed into law by President Trump.

I know people might think me insane when I say this, but Trump’s comments upon signing the bill remind me of Ronald Reagan when he signed compromise bills with the Democrats that were not what he really wanted. Trump calls it a victory, but also said this:

“Without more Republicans in Congress, we were forced to increase spending on things we do not like or want in order to finally, after many years of depletion, take care of our Military,” he wrote. “Sadly, we needed some Dem votes for passage. Must elect more Republicans in 2018 Election!”

Trump continued to praise the bill as a victory, because of the big spending boost to the military. He criticized Democrats for “waste” in the bill. “Costs on non-military lines will never come down if we do not elect more Republicans in the 2018 Election, and beyond,” he said. “This Bill is a BIG VICTORY for our Military, but much waste in order to get Dem votes.”

Though I strongly think we have plenty of waste in the military as well, and that the Defense Department didn’t need any increases and could have been cut considerably, in many ways Trump’s comments here reflect reality. For the American public to get its federal government under control, that public is going to have to vote out the people who presently run it in an uncontrollable manner. And while there are many establishment Republicans to which this description applies, the vast majority of the legislators who are pushing out-of-control spending are Democrats.

San Francisco area #1 in nation for fleeing residents

Fleeing the communist state: The San Francisco area is now #1 in the nation in the number of residents fleeing for more hospitable regions.

Joint Venture Silicon Valley’s own study of the out-migration says workers are moving to Sacramento, Austin, and Portland due to a number of factors. But topping the list is the high cost of housing. “You can’t even contemplate getting into the housing market here,” Hancock said. “And I don’t mean just service workers, but highly skilled professionals. The tech elite are having a hard time affording reasonable housing in Silicon Valley. That makes it difficult for employers to recruit.”

The article however also cites the politics of the region.

Dabak cites crowding, crime and politics as the reasons for her own exodus. “We don’t like it here anymore. You know, we don’t like this sanctuary state status and just the politics,” she said. She plans to sell her home for about $1 million, buy a much larger place near Nashville for less than half that and retire closer to family and friends.

I am reminded of East Germany in the 1950s. Ruled by the Soviets and the communists they installed (whom today we might call radical leftists), it became the only western nation in the world that had a shrinking population, mostly because of the vast numbers of residents that were fleeing to West Germany, where they were free to make a living as they wished. In East Germany’s communist state they were poor and oppressed. In West Germany’s capitalist state they could be prosperous and free.

To solve this problem, Khrushchev built a wall between East and West Germany, to imprison his citizens. When they continued to flee, using the loophole that existed in Berlin (with half its territory controlled by the western Allies), he then built a wall through the middle of the city. It stopped the population loss, while making the residents of his communist bloc prisoners.

What will the leftist radicals who now run California do? As people flee their bankrupt state, will they then decide to build a wall to keep people in? I wonder.

Narwhals love glaciers!

New research tracking fifteen narwhals over four years has revealed that they like to hang out near glaciers that are stable and do not have many calving events.

To better understand what glacier features narwhals prefer, Laidre and her colleagues used data from 15 narwhals outfitted with recorders that tracked each animal’s movements over four years in the 1990s and 2000s in Greenland’s Melville Bay, where narwhals congregate in summer. They combined this data with information about glaciers in Melville Bay over the same time period.

The researchers examined how narwhals behaved at the glaciers and collected information about each glacier’s physical properties to create models of narwhal behavior and tease out the animals’ preferences. “Narwhals like slow-moving, big walls of ice where conditions are still and serene instead of a lot of runoff and disturbance,” Laidre said.

The researchers don’t know why the narwhals prefer these glaciers. They think the freshwater could shock small marine critters that are food for fish, which narwhals eat. Narwhals are also close relatives of beluga whales, which also seek out freshwater in summer to shed their skin, and it is possible there is something similar going on at the glacier front, Laidre said.

This is fascinating research. What is especially refreshing about it is that the press release makes no mention of global warming, a omission that is proper but increasingly rare in the politicized science community.

SSL lawsuit against Orbital ATK to move forward

A judge has ruled that a lawsuit brought by SSL against Orbital ATK, two companies competing for satellite servicing work, can go forward.

The case stems a December 2016 incident where NASA officials notified SSL that there had been unauthorized access to SSL documents related to a NASA “Tipping Point” technology development award on a server at the Langley Research Center. SSL had received that award earlier in the year to work on technologies related to in-space satellite servicing.

That unauthorized access was traced to an Orbital ATK employee, who was subsequently fired by the company. However, SSL said in its suit that as many as six Orbital ATK employees viewed the documents. SSL filed the suit in March 2017 seeking an injunction to prevent Orbital ATK from using any of those documents in its own projects, as well as “other and further relief the Court may deem just and appropriate.”

Both companies have satellite servicing missions planned. What I want is for both to succeed, to provide some competition in the field. Though I suspect this is doubtful, this lawsuit has the possibiliity of killing Orbital ATK’s effort.

New Horizons takes the most distant pictures from Earth ever taken

Kuiper Belt Object 2012 HE85

The New Horizons science team has released three images taken by the spacecraft from almost 3.8 billion miles from Earth, the most distant images ever taken.

The routine calibration frame of the “Wishing Well” galactic open star cluster, made by the Long Range Reconnaissance Imager (LORRI) on Dec. 5, was taken when New Horizons was 3.79 billion miles (6.12 billion kilometers, or 40.9 astronomical units) from Earth – making it, for a time, the farthest image ever made from Earth.

…LORRI broke its own record just two hours later with images of Kuiper Belt objects 2012 HZ84 and 2012 HE85 – further demonstrating how nothing stands still when you’re covering more than 700,000 miles (1.1 million kilometers) of space each day.

The images themselves are not spectacular to look at, though the two images of two different Kuiper Belt objects are the best ever taken of such objects, and certainly contain data that scientists will be able to use. The image on the right is one of these objects, 2012 HE85. For example, note how it does not appear to be round.

This exercise is in preparation for the January 1, 2019 fly-by of 2014 MU69, where the images will be sharp and detailed, and provide us a good look at such a distant object.

NASA approves 2020 launch window for first Dream Chaser flight

Capitalism in space: Sierra Nevada has gotten the okay from NASA to aim for a 2020 launch window for the first flight of its reusable Dream Chaser mini-shuttle.

SNC announced Feb. 7 that it had received “authority to proceed” on that mission using the company’s Dream Chaser vehicle. The mission will launch on a United Launch Alliance Atlas 5 rocket in late 2020. The mission is the first of six in the company’s Commercial Resupply Services (CRS) 2 contract it won in 2016 to transport cargo to and from the ISS. SNC received a CRS-2 contract along with current CRS providers Orbital ATK and SpaceX.

“While we won the contract a couple of years ago, the contract still needed to be validated by a task order,” said Mark Sirangelo, executive vice president of SNC’s Space Systems business area, in a Feb. 7 speech at the Federal Aviation Administration’s Commercial Space Transportation Conference here. That order, he said, is the “biggest step” to date on the program. That flight will be a “full scale, fully operational mission,” he said, even though it will represent the first orbital flight of the Dream Chaser. Orbital ATK and SpaceX, who developed their Cygnus and Dragon spacecraft, respectively, under earlier NASA Space Act Agreements, flew demonstration missions before starting their operational CRS cargo flights.

Do not be surprised if this flight does not launch on schedule. I fully expect that development will push it back into 2021, a delay that would not be unreasonable.

Tiangong-1 reentry now estimated between March 25 and April 17

China’s first space station, a test module called Tiangong-1, is now expected to reenter the atmosphere and crash to Earth sometime between March 25 and April 17.

The Tiangong-1 space lab was launched in 2011 to test docking technology and life support by hosting two crews, but loss of control over the spacecraft’s propulsion means it cannot be deorbited in a controlled manner.

The spacecraft’s orbit is decaying due to atmospheric drag and that process is accelerating as Tiangong-1 runs into denser concentrations of particles at lower altitudes.

The station will break-up during reentry, and most of it will burn up. However, some chunks will hit the ground. The article gives details about how they are tracking it in preparation for reentry.

Off hunting javelinas again

A javelina

Posting on Friday and over this weekend will be nil, as I am leaving tonight, Thursday, and will be in the back country with no phone or internet service on my second javelina hunt. If we bag something early we will be back early, but that can hardly be guaranteed.

For a description of my javelina hunt last February, go here.

Note that there will be an evening pause on Friday night, regardless.

Update: Due to technical issues, I am instead heading out tomorrow afternoon, so posting will resume for the morning hours.

Mars rover update: February 8, 2018

Summary: Curiosity remains on Vera Rubin Ridge, though it has begun moving toward the point where it will move down off the ridge. Opportunity remains in Perseverance Valley, though it has finally taken the north fork down.

Before providing today’s update, I have decided it is time to provide links to all previous updates, in chronological order. This will allow my new readers to catch up and have a better understanding of where each rover is, where each is heading, and what fascinating things they have seen in the past year and a half.

These updates began when I decided to figure out the overall context of Curiosity’s travels, which resulted in my March 2016 post, Pinpointing Curiosity’s location in Gale Crater. Then, when Curiosity started to travel through the fascinating and rough Murray Buttes terrain in the summer of 2016, I stated to post regular updates. To understand the press releases from NASA on the rover’s discoveries it is really necessary to understand the larger picture, which is what these updates provide. Soon, I added Opportunity to the updates, with the larger context of its recent travels along the rim of Endeavour Crater explained in my May 15, 2017 rover update.

Now to talk about the most recent news from both rovers!

Can you spot the racist xenophobic politician in this quiz?

Link here. Here’s the first question:

“Those who enter the country illegally and those who employ them disrespect the rule of law, and they are showing disregard for those who are following the law. We simply cannot allow people to pour into the United States undetected, undocumented (and) unchecked, and circumventing the line of people who are waiting patiently, diligently and lawfully to become immigrants in this country.”

A) Adolf Hitler
B) Donald Trump
C) Barack Obama

Answer: Then-Sen. Obama, news conference, 2005

The quiz continues, each time providing a quote that sounds remarkably like Trump or numerous conservative Republican politicians in discussing the problems of illegal immigration, with the answer instead being almost always Barack Obama or Bill Clinton.

The point here is not that Democratic politicians were once against illegal immigration. No, what this quiz illustrates is how completely insane the left has become since Trump became president. Their hatred of Trump has caused them to accuse him and Republicans of the most ridiculous slanders, based on nothing. Thus, this quiz illustrates how completely unqualified any Democratic politician is that spouts accusations of racism and xenophobia against Trump and the Republicans. Such politicians don’t know what they are talking about, have only a single goal of blocking any actions by Republicans, no matter how sensible, and cannot be trusted with legislative power.

The sad thing is that the voters who put such Democrats into power are not likely to change their votes, as they are as much consumed by a bigoted hatred of Trump and Republicans as the Democratic Party.

Update on Falcon Heavy core stage landing failure

Link here. According to Musk, the reason the core stage hit the water so fast is that some engines did not fire as intended.

He said engineers believed only one of three engines fired during a final burn designed to slow the rocket’s descent before touchdown. The stage only missed the boat by about the length of a football field, but the force of its water impact was enough to “take out” two engines on the nearby drone ship and spray it with debris.

This is proper engineering procedure. They flew a test, and learned something. They now need to figure out why it happened, and fix it.

Linux beats Windows and Apple for security

Another reason I use Linux: A survey of computer security experts confirms that they generally consider Linux superior to either the Windows or Apple operating systems when it comes to security.

Obviously, if you are used to Windows or Apple, making the switch seems daunting. It isn’t, as I know from experience, having been a Linux user now for almost a dozen years. And if you want to try out Linux, all you really need is a spare laptop or desktop, one or two years old, that you aren’t using any more, and to then follow the instructions provided here on Behind the Black by reader James Stephens for Getting and Installing Linux:

Put a flavor of Linux on that old computer, and begin playing with it. Before long you will find that you don’t need Microsoft or Apple anymore.

Obama ignored Russian treaty violations to give it U.S. uranium mining rights

The real Russian collusion: In testimony before Congress an FBI informant outlined today how the Obama administration gave Russian control of the company Uranium One, that owned 20% of the U.S. uranium mining rights, despite being given clear evidence that Russia was providing aid to Iran in violation of treaties.

Campbell [the informant] had provided the FBI with evidence of the criminal network and delivered the information to the FBI. which was monitoring his work as an informant and approving his transfer of bribery money to the Russians. Those transfers, which were made in bulk $50,000 sums and at times delivered in cash, occurred between senior executives of the American transportation company and the Russian executives connected to Rosatom. He had given the FBI irrefutable evidence showing how contracts obtained from the same Russian energy company Tenex, were based on contract bribery and other nefarious actions, he said.

Senior members of the FBI, Department of Treasury, Department of Energy and Department of Justice were also briefed on Campbell’s information and were apprised of the various facets pertaining to Russia’s acquisition of the Canadian company. In fact, Campbell had been told by his FBI handlers that his work had made it at least twice into President Obama’s classified presidential daily briefings.

…Despite the insurmountable evidence collected by Campbell, the Obama administration’s Committee on Foreign Investment in the United States approved Russia’s purchase of Uranium One in the fall of 2010.

The real question that his testimony apparently did not address (though earlier reporting had said it would) is the connection between then Secretary of State Hillary Clinton, who approved the Uranium One deal, her Clinton Foundation that received millions from the Russians at this time, and the $500,000 in speaking fees that Bill Clinton also got from the Russians then. Those fees sure look like a quid pro quo, but this testimony did not provide any evidence to show that.

New budget deal dumps budget caps

The swamp wins again! The new budget deal negotiated today between Senate leaders Mitch McConnell (R-Kentucky) and Chuck Schumer (D-New York) eliminates the sequestration budget caps that for the past half dozen or so years have put at least a few limits on government spending.

The deal removes sequestration budget caps for two years, increases defense spending and also boosts funding for domestic programs that were priorities for Democrats, such as opioid addiction programs. It also raises the debt ceiling until 2019.

It was unclear if the Senate deal will get enough support when it goes to the House.

According to this report, the deal will raise government spending by $300 billion over the next two years.

Even as the two parties make a lot of noise over the FBI scandal, their leaders move to keep the spigot of cash flowing to their buddies, and thus to themselves. And as they do so the federal debt grows, and grows, and grows. And we get closer and closer to outright bankruptcy and collapse.

Update: Trump has endorsed the deal.

“The Budget Agreement today is so important for our great Military,” he wrote on Twitter. “It ends the dangerous sequester and gives Secretary Mattis what he needs to keep America Great.”

“Dangerous sequester”? The sequestration rule has been the only thing that has kept any reins on budget spending for the past few years. In this matter Trump reveals his old liberal Democrat roots.

Mayor of bankrupt Stockton wants to hand out $6000 to every resident

California madness: The 26-year-old mayor of Stockton, California, which went bankrupt in 2012, wants to give every resident $6000 no questions asked.

Stockton is experimenting with a welfare program called “universal basic income,” which gives low-income residents $500 a month, no questions asked. The money is coming from a private grant. The California city, which went bankrupt in 2012, has recently made strides to become more economically viable, but is still struggling.

Mayor Tubbs, who was endorsed by Barack Obama, took office in January 2017. He is Stockton’s first black mayor, and its youngest-ever at age 26. “I feel that as mayor it’s my responsibility to do all I could to begin figuring out what’s the best way to make sure that folks in our community have a real economic floor,” Tubbs said.

Now we have an idea why the city went bankrupt. The money is coming from a private grant, but I guarantee it will not have the results the mayor expects.

New anti-Trump emails: Obama “wants to know everything we’re doing.”

Newly released emails between two anti-Trump FBI agents reveal that not only did they despise Trump, they had contempt for all Republicans and the “ignorant hillbillys” who voted for them, and most important, President Obama wanted “to know everything we’re doing.”

The timing of the texts reveal that Obama was not interested in any investigations of the Clintons, but in the work these agents were doing in trying to build a Russian collusion case against Trump.

More here.

Both links also provide video of Obama speaking just prior to this text’s date where he pointedly claims that he does “not talk to FBI Directors about pending investigations.”

Overall, the evidence here is building that these FBI officials, their superiors, and Obama himself, were conspiring to use the power of the government to attack a political opponent from the opposition party, a direct attack on our democracy.

Falcon Heavy reactions post launch

I could provide links to probably a hundred articles, but most simply say the same things, while generally being awed and excited. The handful below sum things up well, plus provide some additional details:

The first two stories provide a good overview of the excitement caused by the launch. The third story, about California’s tax on rocket launches, is really an op-ed opposing the tax. (I don’t expect that state’s leftist legislature to cancel it.) The third story also outlines what happened, but provides this significant quote from Musk, illustrating starkly how revolutionary this rocket is:

Musk said he personally inspected the landed boosters, adding that SpaceX could even reuse them if it wanted. Even after seeing the results of the launch, Musk said he was having difficulty comprehending the magnitude of the flight, saying it was surreal for him to see such success.

“It can launch things direct to Pluto and beyond. Don’t even need gravity assist or anything,” Musk said. “You can go back to the moon.”

He estimated the total SpaceX investment was over $500 million dollars to develop Falcon Heavy. Musk noted those funds were “all internal,” and not from taxpayers or fundraising.

In other words, the taxpayer now has available, at no development cost, the heavy-lift rocket that NASA has been trying and failing to build for tens of billions since 2004.

Finally, the last story isn’t really about Falcon Heavy, but about how SpaceX is in the driver’s seat in the prices it charges. The company is saving quite a lot by reusing its first stage boosters. For the first initial launches reusing these boosters they offered discounts to get customers to use them. Now they no longer have to, because their normal prices beat everyone else anyway. They can pocket the extra profits.

And all this has happened because of freedom, competition, and the vision of one man. Musk deserves all the accolades he is receiving today.
