Russia to launch twice from Vostochny this year

8:51 am

Russian Deputy Prime Minister announced today that Russia will launch satellites from its new spaceport in Vostochny twice in 2017, first on November 28 and second on December 22.

On July 3, Rogozin said Russia would conduct five launches from the Vostochny space center in 2018. On July 11, Russia’s Roscosmos State Space Corporation head Igor Komarov said the agency was determined to launch up to five carrier rockets for its foreign clients from Vostochny every year starting in 2019.

It appears that the Russian leadership decided to accelerate the launch schedule and move two of those 2018 launches to November and December, 2017. They must be feeling the competitive pressure coming from SpaceX, which has essentially stolen almost their entire share of the commercial launch market.

Google Lunar X-Prize extends deadline

8:39 am

Capitalism in space: The Google Lunar X-Prize has announced that it has extended its contest deadline from the end of 2017 to the end of March 2018 for the finalists to complete their lunar rover mission and win the grand prize of $30 million.

They also announced several additional consolation prizes that all of the remaining five contestants can win should they achieve lunar orbit ($1.75 million) or successfully achieve a soft landing ($3 million), even if they are not the first to do it.

At least one team, Moon Express, will be helped enormously by the extra three months. This gives Rocket Lab just a little extra time to test its rocket before launching Moon Express’s rover to the Moon.

UC-Davis establishes rules to allow free speech

9:35 am

This could be a victory: A working group established by the administration of the University of California in Davis (UC-Davis) has recommended rules that will punish students who disrupt speakers and prevent them from speaking.

[T]he working group recommended the implementation of an “anti-disruption disciplinary rule” that would punish student who disrupt speakers, as was the case during Yiannopoulos’ visit to campus.“Although the determination of what constitutes disruption may be fact-specific and contextual in some cases and require the exercise of official discretion, the campus should clearly delineate disruptive behavior it deems presumptively unacceptable and provide clear notice to students engaging in such behavior that their conduct warrants a disciplinary response,” the working group explains.

Additionally, the report recommends regular “freedom of expression education events” to highlight the “values served by freedom of expression on a university campus.” Among such events, the working group suggests “interactive town halls and workshops” that would include discussion on the “theory of creative political expression to provide compelling examples of other, constructive and expressive options students have to respond to controversial speakers.”

This sounds good, but we will only find out if the administration means it when a conservative speaker decides to come to UC-Davis to speak. The article includes many comments from students who participated in the working group that opposed these recommendations and were hostile to allowing any dissenting voices on campus.

Ten planetary probes track a solar eruption through the solar system

9:02 am

The path of an October 2014 solar eruption was tracked by ten different spacecraft, including Curiosity on the surface of Mars, as its blast moved outward through the solar system.

The measurements give an indication of the speed and direction of travel of the CME [Coronal Mass Ejection], which spread out over an angle of at least 116 degrees to reach Venus Express and STEREO-A on the eastern flank, and the spacecraft at Mars and Comet 67P Churyumov–Gerasimenko on the western flank.

From an initial maximum of about 1000 kilometers per second (621 miles per second) estimated at the sun, a strong drop to 647 kilometers per second (402 miles per second) was measured by Mars Express three days later, falling further to 550 kilometers per second (342 miles per second) at Rosetta after five days. This was followed by a more gradual decrease to 450–500 kilometers per second (280-311 miles per second) at the distance of Saturn a month since the event.

The CME was first detected by solar observatories Proba-2, SOHO, Solar Dynamics Observatory, and STEREO-A.It was then tracked as it moved outward by Venus Express, Mars Express, MAVEN, Mars Odyssey, Curiosity, Rosetta, Cassini, and even New Horizons and Voyager 2.

On my last appearance on Coast to Coast, I was specifically asked if the probes to Venus, Mars, and other planets have the capability to track solar events. I knew that the Voyager spacecraft had equipment to do this, but was unsure about other planetary probes. This article answers that question.

More Russian launch delays

8:50 am

Three stories out of Russia today suggest that that country’s aerospace industry has not yet fixed all of its quality control problems.

The last two stories both refer to the launch of Germany’s Spektr-RG, which was originally supposed to launch in 2014. The most recent schedule said the astronomical observatory would be launched in September 2018. That they need an extra month in order to “integration and ground development of the Spektr-RG spacecraft” does not seem out of line. At the same time, that they do not provide any reasons for the delay raises questions.

Meanwhile, that the Proton rocket for the Amazonas-5 launch has not yet been shipped seems incredible. The September 9 launch date was announced on August 9. You would expect that by now Russian companies would know exactly how long it takes to get a rocket to the launchpad. This suggests another more fundamental problem with the rocket that they are not revealing.

I know I am being a bit harsh on the Russians here. A more positive spin (which also might be true) might be that they are finally getting a handle on their quality control issues, and the result is these few additional delays as they clean things up.

Radical left calls for more violence

11:31 pm

A wide range of leftist radical groups, most of which have been involved in the variety of violent attacks in the last year against conservatives, Republicans, and Trump supporters, are now calling for even more violence against anyone who opposes them.

Many of the same groups that have organized violent demonstrations in Berkeley, California and elsewhere are now calling for an aggressive response to the violence in Charlottesville. Far-left “anti-fascist” (or antifa) figures are advising agitators to do the job that police won’t: shutting down “fascists” and preventing them from organizing.

Radical left-wingers have for months justified violence as a way to fight back against “fascism” and “racism” — terms that they have applied not just to white nationalist fringe groups but to prominent figures on the right as well. “Charlottesville is just the beginning. If the alt-right can get away with murder there, none of us will be safe. We have to stand up to white supremacists, we have to shut down and chase out these bigots every time they try to organize, or else they will kill more people,” reads one poster created by anarchist group CrimethInc, a self-described “international network of aspiring revolutionaries.”

Read the whole article. If you have any doubts these are leftist groups, note that several condemn capitalism and democracy. Moreover, if you have read any history about the organizing tactics used by the Nazis in Germany, the Fascists in Italy, and the Communists in Russia and China, you will find the language and tactics here very familiar.

3D printing and how it will change what things look like

9:29 pm

Link here. The article not only outlines some of the newer developments in 3D printing, it gives a nice look at how that technology is literally going to change what the things it builds look like.

Simple shapes are popular in human designs because they’re easy. Easy to design, especially with CAD, and easy to manufacture in a world where manufacturing means taking a big block or sheet of something, and machining a shape out of it, or pouring metals into a mold.

But manufacturing is starting to undergo a revolutionary change as 3D printing moves toward commercially competitive speeds and costs. And where traditional manufacturing incentivizes the simplest shapes, additive manufacturing is at its fastest and cheapest when you use the least possible material for the job. That’s a really difficult way for a human to design – but fairly easy, as it turns out, for a computer. And super easy for a giant network of computers.

The result: a stronger object, less weight, and less cost.

North Korea appears to back down

6:27 pm

A news report today out of North Korea suggests that its leader, Kim Jong Un, has stepped back from a plan to test fire four missiles in the direction of Guam.

This could be related to China’s decision this week, under strong pressure from the Trump administration, to finally go along with UN sanctions and ban imports of iron, lead, and coal from North Korea.

A celebration of hate and ignorance

1:34 pm

The last few days have not been good ones for American free speech and freedom. Not only have we seen violence perpetrated to silence the free expression of dissent, we have seen an effort after the fact to use that violence as a club for destroying any opposition to the liberal and leftist dogma that dominates the American political and academic community.

The following links will provide a nice overview of how our cultural elites, especially on the left, have responded to this weekend’s terrible events in Charlottesville, Virginia, where one person was killed and almost twenty injured when a car rammed into a crowd of competing racist demonstrators.

That is how our elites responded, not with conciliatory remarks aimed at bringing people together, but with anger and hate, hate of Trump, hate of the Republican Party, hate of the NRA, hate of whites, hate for anyone that dared disagree with their leftist agenda. Then, when Trump issued a statement condemning all violence in the name of bigotry, the response was equally hateful:

The gentle storms of Saturn

10:03 am

Saturn's gentle storms

Cool image time! The Cassini image above, cropped and reduced slightly, shows a close-up view of Saturn’s cloud tops, taken during Cassini’s May 18, 2017 fly-by.

Clouds on Saturn take on the appearance of strokes from a cosmic brush thanks to the wavy way that fluids interact in Saturn’s atmosphere. Neighboring bands of clouds move at different speeds and directions depending on their latitudes. This generates turbulence where bands meet and leads to the wavy structure along the interfaces.

What I see is a much less turbulent storm pattern, when compared with Jupiter. This is not to say that the weather of Saturn is quiet or peaceful, for it certainly cannot be, considering the gas giant’s size and the depth of the atmosphere. Still, this image suggests that the turbulence is less violent here, possibly because Saturn is farther from the Sun and is hit with less solar energy, and because Saturn is smaller and thus produces less of its own internal energy.

Either way, it is beautiful and mysterious, in the way are all such images of alien places.

New research challenges theories on Earth formation

9:47 am

The uncertainty of science: New research about the Earth’s core contradicts the presently accepted theories about the Earth’s formation.

New geochemical research indicates that existing theories of the formation of the Earth may be mistaken. The results of experiments to show how zinc (Zn) relates to sulphur (S) under the conditions present at the time of the formation of the Earth more than 4 billion years ago, indicate that there is a substantial quantity of Zn in the Earth’s core, whereas previously there had been thought to be none. This implies that the building blocks of the Earth must be different to what has been supposed.

The research suggests that the Earth is made up of materials different than expected, which means that the materials from the solar system from which it formed are different than presently believed, which also means that present formation theories will need to be revised.

Rocket Lab looks to second test flight of Electron

9:23 am

Capitalism in space: Having completed its review of its first May test flight of its Electron rocket, Rocket Lab now looks to the second test flight.

The article gives a good overview of the results from the first test flight. It also has this tidbit:

The second of Rocket Lab’s three planned test flights is scheduled later this year. If that launch goes well, the company will likely delete the third demonstration mission, and the first commercial Electron flight could be ready for takeoff by the end of December, Beck said last week.

“We’ve got the next test flight rolling out out to the pad in about eight weeks’ time,” Beck said. “If it’s a really good clean flight, we’ll probably accelerate into commercial operations.”

If they follow this schedule, then the next flight will be in mid-October, and the Moon Express launch of its lunar rover will occur in mid-December, just in time to win the Google Lunar X-Prize.

SpaceX launch today

9:14 am

SpaceX is scheduled to resume launches at Kennedy, after a month of range upgrades by the Air Force. You can watch it live here, or here.

Launch is presently scheduled for 12:31 Eastern time to send a Dragon capsule to ISS. At the moment all looks good for an on-time launch.

The launch was a complete success, including a picture-perfect first stage landing at Kennedy.

Amazon refunding customers who bought fake eclipse glasses

9:43 am

Amazon is issuing refunds to any customers who bought fake eclipse glasses through the site.

It is essential for people who are going to view the eclipse to understand that as long as the Sun is even partially visible, even by a sliver, it can cause significant eye damage if viewed without proper protection. Make sure your eclipse glasses or filters are safe! And remember, only during the short 2 minute or so totality that will occur in the narrow strip across the country will it be safe to look at the Sun without protection. Even so, you must do so with great caution so that you don’t mistakenly view the Sun unprotected when it is partially exposed.

New Japanese private joint venture to enter smallsat rocket industry

9:35 am

Capitalism in space: A Japanese private joint venture has formed with the intent to compete in the new smallsat rocket industry.

The new company is led by President Shinichiro Ota, a former industry ministry bureaucrat and once the head of the Japan Patent Office. NGSRDP will initially be based at Canon Electronics’ headquarters, studying technologies and costs with the hope of starting commercial operations as early as this year.

The joint venture has set a price point of 1 billion yen ($9.1 million) or less per launch — an amount seen as competitive against overseas rivals. At present, plans call for a rocket smaller than the Epsilon rocket currently under development by the Japan Aerospace Exploration Agency, or JAXA, but larger than JAXA’s SS-520 minirocket.

The four companies had been discussing formation of a small rocket company for about three years. President Ota has said that the “time is ripe” for the joint venture. IHI Aerospace has played a key role in the development of Epsilon, while Canon Electronics has been involved in the SS-520 project.

I would say that this is a clear sign that the competition in the smallsat rocket industry is definitely heating up.

Note that the name of this new joint venture, New Generation Small Rocket Development Planning (NGSRDP), is quite horrible. I hope they come up with something better soon for marketing purposes.

Japanese launch scrubbed due to problem with rocket

9:29 am

Japan’s space agency JAXA scrubbed a Saturday launch of a GPS satellite because of a possible leak in the H2-A rocket’s helium pressurization system.

The Japanese have not released much information. However, the problem might be more serious than normal, because the rocket was still on the launchpad on Sunday, almost a day after the launch itself was scrubbed. Normally when a launch is scrubbed they move quickly to safe the rocket and get it back into the assembly building to assess the issue. That the rocket was not moved suggests they might be having a problem doing this.

Cassini’s last close look at Titan

9:44 am

Titan's magic lake district

The Cassini science team has released the last radar swath that the spacecraft will take of Titan, imaged on April 22.

You can see the full swath up close here. The image above is my crop of the section on the swath’s right portion, showing the shoreline of the hydrocarbon lake Ligeia Mare, where periodically an island has been seen by radar to intermittently appear and disappear.

No “island” feature was observed during this pass. Scientists continue to work on what the transient feature might have been, with waves and bubbles being two possibilities.

The fly-by also took the first, and last, depth measurement of 8 other lakes, finding that they all had the same depth, suggesting they are connected by an underground “water” table. In this case, it ain’t water, but liquid hydrocarbons like methane.

Virgin Orbit gets another launch contract

9:26 am

Capitalism in space: Virgin Orbit’s LauncherOne rocket has gained another launch contract, this time from an Italian smallsat company.

Italian small satellite builder Sitael has signed Virgin Orbit to send a technology demonstration satellite into low-Earth orbit next year. Sitael’s µHETsat, a demonstrator for a new electric propulsion system built with the European and Italian space agencies, will fly on LauncherOne “mid-next year,” Dan Hart, Virgin Orbit Chief Executive, told SpaceNews Aug. 11.

Virgin Orbit is preparing to begin commercial services with LauncherOne, its air-launched small satellite orbital vehicle, in 2018. Other customers for the launch system, which can carry 500 kilograms to LEO, include NASA, OneWeb, and Sky and Space Global.

This story further strengthens my prediction that LauncherOne (in development for 5 years) will fly in space long before SpaceShipTwo (in development for 13 years).

Unexpected big storm on Neptune

9:17 am

The uncertainty of science: Astronomers have spotted a new very big storm on Neptune, occurring unexpectedly near the plane’s equator.

A large, high-pressure vortex system deep within Neptune’s atmosphere is thought to drive the white storm clouds. As methane gases rise up in the vortex, they cool below the condensation temperature, forming clouds in the same way that water vapor does on Earth.

The location of the vortex caught astronomers by surprise, though. “Historically, bright clouds have occasionally been seen on Neptune, but usually at latitudes closer to the poles, around 10 to 60 degrees north or south” says de Pater. “Never before has a cloud been seen at, nor close to the equator, or anything so bright.”

Neptune is the windiest planet in the solar system, with observed equatorial wind speeds of up to 1,000 miles per hour (450 m/s). Since wind speeds vary drastically with latitude, a storm crossing more than 30° of latitude should quickly break apart. Something, such as an underlying vortex, must be holding it together. But a long-lasting vortex right at the equator would be hard to reconcile with our current understanding of the planet’s atmosphere.

I think any theory about Neptune’s weather should treated with a great deal of skepticism. I am sure the theories are based on what is known, but what is known is very little. Until we have been able to observe this gas giant up close and for decades, our understanding of its weather is going to be sketchy, at best.

Chinese engineers and astronomers fight over new telescope design

9:10 am

A dispute over the design of a new Chinese optical telescope has broken out between the astronomers who will use it and the engineers who will build it.

In April, an international committee convened by [Chinese Academy of Science’s] Center for Astronomical Mega-Science, which is responsible for the project, reviewed the competing designs and recommended the three-mirror option [the preference of astronomer Jiansheng Chen and China’s astronomers]. On 10 July, [Xiangqun Cui, the instrument’s chief engineer] organized her own review committee that picked the SYZ design as better. Cui’s panel “leaned toward one side,” Chen says. And one member says that the three-mirror design was not sufficiently presented, partly because no one from the Huazhong team was there. Cui and Su explain in their open letter that a member of their own group who knows it well introduced the Huazhong design. “Members were repeatedly reminded they could abstain from voting,” they write. One-third of the 21 committee members did abstain.

Meanwhile, to date, more than 130 young astronomers have signed an open letter to the astronomical community urging that the recommendations of the international panel be respected.

The fundamental disagreement, according to Chen, is “whether a large science project should be technically or scientifically oriented.” Cui and Su say the choice is between incorporating “rapidly developing new technologies” that ensure a long life for the facility, or “simply replicating a 10-meter telescope built 30 years ago.”

This spat reinforces the impression gained from the recent other story about China’s inability to find a manager for its newly built radio telescope. Its top-down management approach (where decisions are made by well-connected powerful bureaucrats at the top of the chain of command) produces office politics that generally does not lead to good technical decisions.

White nationalist protest in Virginia

11:33 pm

Racism goes all around: A demonstration of white nationalists gathered today at the University of Virginia, holding torches and shouting pro-white chants.

Sharing a photo of the torch-bearing march on Friday, Unite the Right organizer Jason Kessler wrote on Twitter, “Incredible moment for white people who’ve had it up to here & aren’t going to take it anymore. Tomorrow we #Unitethe Right #Charlottesville.”

Prominent white nationalist Richard Spencer, who led a similar march in Charlottesville in May, was also at the rally on Friday night.

You hate people merely because they are white, and what you will get is alliances forming to defend whites, focused entirely on their race. The result is that everyone becomes bigoted and racist.

It is important to remind everyone that no one has been a slave in the United states in more than 150 years, and discrimination solely because of race ended pretty much a half century ago. The nation, which is dominated by whites, elected a black president twice in the past decade. For minorities to hate whites today is absurd, and can only be founded on the basis of race hatred. For white leftists to do it is even more absurd, and is the epitome of self-hatred.

As always, the battle here is between those who treat each person as an individual, and those who can only see them as members of a group. The former believes in individual freedom and personal responsibility. The latter believes in bigotry and racism. I proudly rank myself in the former group. To which group do you belong?

A memo from Google advising employees on correct thought

10:33 pm

Link here. This memo clarifies for everyone what is expected of Google employees. I especially find this quote informative:

Please remember, as you no doubt read in the Employee Handbook, Google’s commitment to diversity is complete and unequivocal. Any variance from diversity is not permitted and will be dealt with immediately. It is only when all of us think exactly the same thoughts that we can achieve perfect diversity.

Of course, Google is also completely committed to the advancement of science and human knowledge. If history has taught us anything, it is that science can only flourish where the allowable topics of discussion are highly circumscribed. Approved subjects of conversation are posted throughout the campus, so please look before you speak.

I believe some of the problem lately has been a simple misunderstanding of my last memo. Unfortunately, I mistyped that Google “approves of free speech.” I meant to write that Google must “approve free speech.” I want all of our employees to feel perfectly free to express themselves however their political, moral, or religious beliefs impel them; provided of course that they receive prior written authorization.

Read it all. It really explains everything.

An article in New York magazine claims blonde hair is racism

8:32 pm

Want to see bigotry on display? Read this New York magazine article: Political Peroxide: Blonde privilege

Attributes associated with whiteness — light skin, narrow noses — have dominated American beauty ideals as long as there’s been such a thing. Which means that blondness has always been … charged: The ’50s gave us Doris Day, who once said that her only ambition ever had been to “be a housewife in a good marriage” (“Preordination had other plans”). To be blonde was to be a good American woman, pure of intention and heart — which implied also, of course, that to be a good American woman, pure of intention and heart, meant being blonde. Betty was blonde, Veronica was trouble. Ditto Sandy and Rizzo. Hitchcock liked to cast blondes because he said they made the best victims: “The color was virgin snow that shows up the bloody footprints.”

Fox News and Donald Trump have given blonde hair a new chapter: Now, blonde is the color of the right, for whom whiteness has become a hallmark. Over the past decade or so, as inclusiveness became the hallmark of Obama-era liberals, the left found feminist icons in Rachel Maddow, Samantha Power, and Michelle Obama, who make no apologies for their failure to fit traditional ideals. But #MAGA, Fox News America is a place where all the classic signifiers of privilege and wealth work on overdrive: country-club-issue blue blazers with brass buttons and khaki pants, and above all else, for women, that yellow-blonde, carefully tended hair — a dog whistle of whiteness, an unspoken declaration of values, a wink-wink to the power of racial privilege and to the 1980s vibe that pervades a movement led by a man who still believes in the guilt of the Central Park Five. During that Republican Preppy Handbook era, when Dynasty and Dallas were on TV, the type of conspicuous ostentation that would lead a real-estate developer to sheath his entire apartment in gold leaf was actually in vogue. Look at the movies: Jake’s girlfriend in Sixteen Candles with the lush swoop of thick, blonde locks that ended up stuck in a door (losing the boyfriend to a redhead of all things meant, literally, losing that luscious hair). Johnny, the villain of the Karate Kid films, had a decisive swoosh of blond hair that obscured his headband. We knew, the moment we saw that hair, that small, ethnic Daniel was up against more than another teenager, he was up against privilege itself. [emphasis mine]

Not only is this incredibly stupid, it reeks of hatred and bigotry. You have blond hair? You must associate with white supremacists. You choose to dye your hair blond? You must be a white supremacist!

Don’t be surprised when these leftwing progressive bigots take the next step and strongly suggest that we need a final solution to this problem of “whiteness,” that maybe we should round up all these evil whites so they can’t do society any harm anymore.

Mars rover update: August 11, 2017

12:34 pm

Summary: After a two week hiatus because the Sun was between the Earth and Mars and blocking communications, both rovers are once again on the move.

Curiosity

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

Curiosity panorama, Sol 1782

Vera Rubin Ridge close-up

Since my last update on July 12,, Curiosity spent most of the month waiting out the solar conjunction that placed the Sun between the Earth and Mars and blocked communications. In the past few days, however, the rover has begun to send down images again while resuming its journey up Mt. Sharp. The panorama above, reduced to show here, was taken by the rover’s left navigation camera, and shows the mountain, the ridge, and the route the rover will take to circle around the steepest sections to get up onto the ridge. To see the full resolution panorama click on the picture.

To the right is a full resolution section of the area in the white box. As you can see, the geology of the ridge is many-layered, with numerous vertical seams or cracks. In order to track the geological changes across these layers as the rover climbs, the science team is as expected taking a systematic approach.

Lately, one of our biggest science objectives is to conduct bedrock APXS measurements with every 5-meter climb in elevation. This allows us to systematically analyze geochemical changes in the Murray formation as we continue to climb Mount Sharp. Yesterday’s drive brought us 6 meters higher in elevation, so another touch and go for today it is!

Below is a cropped and reduced resolution image of the most recent orbital traverse image, dated sol 1754. The dotted line shows where I think the rover’s has traveled in the last 28 sols. I have also annotated what I think is the point of view of the panorama above.
