Vector Space Systems plans launches from Kennedy

The competition heats up: Vector Space Systems will this weekend erect a test version of its two-stage Vector-R rocket and launch platform for display at the Kennedy Space Center Visitor Center.

CEO Jim Cantrell also “will announce the intention of the company to use the launch facilities in the future,” according to Space Florida. The two-stage Vector-R — the “R” is short for Rapid — stands 42 feet tall and measures 42 inches around, and is designed to deliver micro-satellites weighing up to about 135 pounds to orbit. The rocket is expected to debut in 2018, flying up to six times. The company eventually envisions launching 100 or more times a year.

Much of this sounds like a bit of PR aimed at the public, not an actual flight plan. However, if they are prepping for an eventual launch at Kennedy there is also no reason they shouldn’t hype that fact beforehand.

More strike actions delay Ariane 5 again

Protests by local workers that have blocked roads has forced Arianespace to once again delay the Ariane 5 launch of two commercial satellites.

Local newspaper France Guyane reports that local electricians, hospital employees, farmers and transportation workers — including the drivers that transport the Ariane 5 rockets — are among those protesting working and living conditions in the South American town that’s home to Europe’s main launch center. Locals blocked roads around Kourou Monday and Tuesday, preventing Arianespace from transferring the rocket from the final assembly building at the spaceport to the launch zone. Evry, France-based Arianespace launches the Ariane 5, Soyuz and Vega rockets from the Guiana Space Center.

…Local employees of Endel, the French industrial maintenance company that trucks the Ariane 5 rockets for Arianespace, are striking to reopen wage negotiations. Those discussions began Monday night, but failed to reach an agreement, according to France Guyane. The paper reports that other members of the union UTG, as well as the French Democratic Confederation of Labor (CDTG) and Force Ouvrière unions, are also involved in various demonstrations.

The Guyanese Union of Road Transport (UGTR) is also protesting the use of foreign trucks from the European construction company Eiffage, France Guyane says. CNES in July awarded Eclair6, a consortium led by Eiffage, a $222.2 million contract 2016 to build the launch facility for the future Ariane 6 rocket. UGTR said it asked the spaceport not to bring in foreign trucks to do work that that its members could do with equally capable trucks of their own.

None of this is going to help Arianespace in its effort to compete in the modern very aggressive launch industry.

Rocket Lab raises $75 million

The competition heats up: Rocket Lab announced today that it has raised an additional $75 million in investment capital.

The new funding round is led by venture capital firm Data Collective, with contributions from another VC firm, Promus Ventures, and an undisclosed investor. Several prior investors, including Bessemer Venture Partners, Khosla Ventures and K1W1, also participated in the round.

Rocket Lab said the Series D round brings the total raised by the company to $148 million, and values the company at more than $1 billion. Rocket Lab announced a Series B round of unspecified size in 2015, and Peter Beck, the company’s chief executive, said the company did an unannounced Series C round in the interim involving only existing investors.

In an interview, Beck said the money will go towards increasing the production capacity for its Electron rocket, set to make its debut later this year. “This is really all about scaling,” he said. “The funding is all about producing the vehicle in much more significant numbers.”

They say they will make their first launch in the coming months, but remain vague about specific dates.

Republican healthcare bill faces defeat in House

It appears the Republican leadership lacks the votes in the House needed to pass its Obamacare replacement bill.

It appears that the Freedom Caucus in the House is generally holding firm, with more than 21 members agreeing that this is a bad bill, just as bad as Obamacare. Why vote for it, and make yourself a partner in this bad business? Consider for example this quote:

Rep. Rod Blum (R-Iowa), one of the few Freedom Caucus members who has a close relationship with GOP leadership, said Trump’s remarks in conference — and the building pressure — just “steels my resolve.”

“The way it stands right now, no,” he would not vote for the bill, Blum told POLITICO. “Not because of the Freedom Caucus, but because I’m a free-marketer and I’m a businessman. … And the present bill doesn’t give us a free market. I want health insurance premiums to come down. … This bill doesn’t give us a free market.”

The Republican leadership was able to successfully pass numerous full repeals of Obamacare when Obama was president and could veto them. Now that we have Trump, a president who will sign a repeal, they suddenly seem incapable of finding where they put those repeal bills. Very shameful.

Repeal the thing. Cleanly. This is what the American people want. They will thank you for it.

The changes seen by Rosetta on Comet 67P/C-G

A new study released today describes in detail the many changes seen by scientists in the data collected by Rosetta during its two years in close proximity to Comet 67P/C-G.

“We saw a massive cliff collapse and a large crack in the neck of the comet get bigger and bigger,” said El-Maarry. “And we discovered that boulders the size of a large truck could be moved across the comet’s surface a distance as long as one-and-a-half football fields.”

In the case of the boulder, Rosetta’s cameras observed a 282-million-pound (130-million-kilogram), 100-feet-wide (30-meter) space rock to have moved 150 yards (460 feet, or 140 meters) from its original position on the comet’s nucleus. The massive space rock probably moved as a result of several outburst events that were detected close to its original position.

The warming of 67P also caused the comet’s rotation rate to speed up. The comet’s increasing spin rate in the lead-up to perihelion is thought to be responsible for a 1,600-foot-long (500-meters) fracture spotted in August 2014 that runs through the comet’s neck. The fracture, which originally extended a bit longer than the Empire State Building is high, was found to have increased in width by about 100 feet (30 meters) by December 2014. Furthermore, in images taken in June 2016, a new 500- to 1,000-foot-long (150 to 300 meters) fracture was identified parallel to the original fracture.

“The large crack was in the ‘neck’ of the comet — a small central part that connects the two lobes,” said El-Maarry. “The crack was extending–indicating that the comet may split up one day.”

It is almost a shame that Rosetta did not see that break-up. The images would have been breath-taking, and the science learned priceless.

The rings of Saturn

The rings of Saturn up close

Cool image time! The image to the right, cropped to post here, is part of one of the closest and highest resolution images that Cassini has yet taken of Saturn’s rings. The image was taken in January during one of the spacecraft’s ring grazing orbits, and has a resolution of 2,300 feet per pixel. And yet, as noted by the Cassini science team, “Even at this level of detail, it is still not fine enough to resolve the individual particles that make up the ring.”

In prepping the image, all I did was crop it to show the closest rings. I purposely did not reduce its resolution, so that you can see that no individual particles are visible. The rings of Saturn are truly made up of billions of small objects, behaving in many ways like liquid floating in the gravity well of Saturn. If you don’t believe me, download the full image and zoom in on it as much as you like. All you will see are pixels.

The fundamental science question therefore is not how Saturn’s rings behave (though this is certainly important and quite fascinating) but why did those rings end up the way they are. No other planet has rings anything like Saturn’s in their density and make-up. Why? Are Saturn’s rings a normal process that only occurs for short times around planets, which is why only Saturn has these types of rings at present? Or is it a rare event, so rare that we happen to be very lucky to see such a thing at all?

Even more important, Saturn’s rings and their behavior are likely linked closely to the same phenomenon that describe the formation of planets around a star. The more we can learn about why these rings exist, the more we will learn about why planets exist, both here circling the Sun as well as around stars everywhere else.

Trump signs NASA authorization

President Trump today signed the NASA authorization bill, initially written and sponsored by Senator Ted Cruz.

The most significant aspect of this authorization is what is not in it. The bill outlines what Congress wants NASA to focus on, and makes literally no mention of any Earth science research at all. Essentially, it tasks NASA to focus on space exploration, and space exploration only.

In many ways this is merely a symbolic act, since it is the budget that really determines what NASA will do, and the budget that Trump put forth last week only cut NASA’s Earth science budget by 5%. Nonetheless, the authorization bill gives us a sense of where the politics are heading. I expect that by the time Congress gets done with NASA’s budget there will be more cuts to that Earth science budget.

SpaceX signs lease for Florida warehouse to refurbish 1st stages

The competition heats up: SpaceX has signed a five year lease for a Florida warehouse near Port Canaveral store and refurbish its recovered Falcon 9 and Falcon Heavy first stages.

This lease just firms up the reality that SpaceX is shifting from expendable first stages to a fleet of reusable first stage. Any rocket company that does not do the same is going to be left in the dust.

Ariane 5 launch delayed by labor strike

The launch of two communications satellites on an Ariane 5 was delayed today by a strike at Arianespace’s French Guiana spaceport.

A work stoppage at the Ariane 5 rocket’s launch base in South America prevented rollout of the booster to the launch pad Monday, pushing back the liftoff of two communications satellites for Brazil and South Korea until at least Wednesday.

The fully-assembled launcher was set to roll out of the final assembly building Monday morning for the 1.7-mile (2.7-kilometer) journey to the ELA-3 launch zone at the Guiana Space Center. Arianespace officials were aiming for a launch attempt Tuesday evening.

But the rollout did not happen due to a “social movement” at the spaceport, according to Arianespace. Officials blamed the postponement on a strike among a segment of the workforce at the Guiana Space Center, which is managed by CNES, the French space agency, with support from the European Space Agency and numerous European contractors.

The article suggests that this was not a sanctioned strike, based on the expiration of a contract. Instead it appears to have been a wildcat strike, created to apply the most pressure in order to blackmail the company into giving the strikers more money. If so, and if Arianespace agrees to terms, its labor relations in French Guiana are going to decline quickly.

Conservatives “violently threatened” at Lutheran college

Fascists: A survey of conservative students at St. Olaf College in Minnesota has found that many have been “violently threatened” because of their political beliefs, with most finding they do not have the ability to express their beliefs in public on campus.

On the night of the election, a student in the Pause threatened to beat up [College Republicans President Emily] Schaller, calling her a “f***ing moron.” Over the next couple of days, she overheard multiple students threaten to hurt the next conservative or Republican they saw. Vice President of St. Olaf College Republicans Kathryn Hinderaker ’19 had a similar experience.

“I think one of the hardest things was, the second day, I went into Buntrock and someone yelled from the bottom, ‘if you voted for Trump, you better be f***ing scared.’ Everyone clapped and applauded,” Hinderaker said. “Obviously, it didn’t feel super safe.”

This story is only a sample, but it illustrates the fascist and totalitarian culture of the left. I just wish that these conservatives had more courage. Had I been a student in that class where everyone applauded the idea of intimidating Trump voters I would have stood up and said, “Come on, show me how much you stand for liberty and freedom of speech and try and shut me up!”

The only proper response to a bully is to get in their face and tell them they are one. That always stops them in their tracks. Backing down to them in turn only emboldens them, and it certainly doesn’t make you safer.

College eliminates English and math placement tests

The coming dark age: A West Virginia community college has stopped giving English and math placement tests, while also eliminating any comparable remedial classes.

A careful read of the article suggests that this decision is a desperate attempt by the college to deal with its influx of unqualified students, as noted by this quote:

“We are still getting some students who literally cannot read above a third-grade level, and I have never learned how to help such students,”

The college still wants these students to attend (which is a cash cow for the college) but it finds itself struggling to find the right approach for teaching them. Since there is no right approach (these individuals should simply not be in college), the situation results in a poorer learning environment for everyone.

The layered mesas of Mars

The mesas of Uzboi Valles

Cool image time! The image above, reduced and cropped to post here, shows the layered deposits and complex erosion that has taken place in this area of Mars dubbed Uzboi Vallis. As noted at the Mars Reconnaissance Orbiter post,

Layered deposits in Uzboi Vallis sometimes occur in alcoves along the valley and/or below where tributaries enter it. These deposits may record deposition into a large lake that once filled Uzboi Vallis when it was temporarily dammed at its northern end by the rim of Holden Crater and before it was overtopped and breached allowing water to drain back out of the valley.

It is important when looking at these erosion patterns, including the strangely shaped rippled sand dunes scattered through the larger image, that wind possibly plays an even more important part in causing erosion on Mars than liquid water might have in the far past.

Either way, the terrain here has the same stark and fascinating beauty as that seen in the American southwest. If we can ever make it possible to live on Mars, this will definitely be a place to visit when on vacation.

Japan launches military satellite

Japan yesterday successfully launched a military surveillance satellite, dubbed the Information Gathering Satellite Radar 5 (IGS Radar-5).

Japan started the IGS program in 1998, presumably in response to North Korean missile tests around that time that sent missiles close to, or flying over, Japan.

In the years since, North Korea has repeatedly threatened to annihilate Japan (and South Korea and the United States), and continued to develop its nuclear-weapon and missile programs. The IGS satellites keep tabs on such efforts, help the Japanese government respond to natural disasters and perform several other functions, experts believe.

The first IGS craft lifted off in 2003. IGS Radar 5 is the 15th one in the program to take flight, though not all have made it to orbit. Two were lost to a launch failure in November 2003.

The terrorist protesters in North Dakota

Fascists: The protesters in North Dakota who had tried for the past year to prevent construction of an oil pipeline appeared to spend as much time threatening the families and children of police officers as they did protesting the pipeline.

While protesters were fueling worldwide outrage and fundraising over allegations of police brutality, an aggressive cohort of agitators was terrorizing the families of law-enforcement officers with threats of death, rape and arson. “There were threats made to us, mostly that they were going to come burn down our houses or rape us while our husbands were gone,” said Allison Engelstad, who’s married to Jon Engelstad, a sheriff’s deputy in Morton County, North Dakota.

She had good reason to fear that protesters knew where they lived. The North Dakota State and Local Intelligence Center compiled a 41-page document of social media posts with threats along with photos, names, addresses and contact information for officers involved with the protest. “Every one of these cops has familys [sic] … Make there [sic] family pay,” read one Facebook post.

A live video feed taken from a January protest on the Backwater Bridge includes the voice of an activist shouting, “We’re going to gang-rape,” “Watch your family,” and “We’re going to kill your daughters, your mothers, your fathers, your grandparents, even you!” [emphasis mine]

I think even more revealing is this tidbit from the article:

Figures released March 1 by law enforcement showed that 661 of the 709 arrests involved out-of-state protesters. Of those arrested, 227 had a total of 1,503 previous citations and charges, including domestic violence, child abuse, robbery, burglary, drug possession and driving under the influence.

This was not a grassroots campaign. This protest was staged, and its intent was hostile to America and to the people who live in it. Pay close attention to which politicians align themselves with this protest, because that will reveal to you what they really believe.

Want to watch a nuclear bomb go off? You can!

Engineers at Lawrence Livermore National Laboratory (LLNL) have obtained declassified films of many of the nuclear tests performed by the U.S. from 1945 to 1962 and are digitally scanning them and preserving them for posterity.

Conducted by LLNL weapon physicist Greg Spriggs and a team of film experts, archivists, and software developers, the project’s goal was to track down as many as possible of the ten-thousand 2,400 frames per second reels of film. This was because the cine film, and its immense historical and scientific value, was in danger of being lost for all time. The reels were mostly of acetate stock that was not stored under anything like ideal conditions and was slowly decaying or being attacked by fungus and microbes.

“You can smell vinegar when you open the cans, which is one of the byproducts of the decomposition process of these films,” says Spriggs. “We know that these films are on the brink of decomposing to the point where they’ll become useless. The data that we’re collecting now must be preserved in a digital form because no matter how well you treat the films, no matter how well you preserve or store them, they will decompose. They’re made out of organic material, and organic material decomposes. So this is it. We got to this project just in time to save the data.”

You can view a number of the films at the second link above. I have embedded below the fold just one, from Operation Teapot in 1955. This was a series of 14 tests in Nevada. In this particular video the explosion occurs in the air, and you can sense the incredible force of the explosion when the shock wave hits the ground and bounces back, producing the mushroom cloud. Not much would have survived that impact.

SpaceX successfully launches commercial satellite

The competition heats up: SpaceX tonight successfully launched Echostar 23.

This launch is almost four weeks after their last launch, which sent a Dragon capsule to ISS. Their goal this year has been to do one launch every two weeks, a goal they have not yet reached. The next launch, which will also place a commercial communications satellite into orbit, is tentatively set for March 27, and will also be the first launch that reuses a first stage. If they make that happen it will be first time they have hit the two week launch rate this year. They will then try to follow with another Dragon resupply mission, this time reusing a Dragon capsule for the first time.

Less evidence of dark matter in early universe

The uncertainty of science: Astronomers have discovered less evidence of dark matter surrounding galaxies in early universe.

Stars in the outer regions of some far-off galaxies move more slowly than stars closer to the center, indicating a lack of dark matter, astronomer Reinhard Genzel and colleagues report online March 15 in Nature. If confirmed, the result could lead astronomers to reconsider the role dark matter played in early galaxy evolution and might also offer clues to how nearby elliptical galaxies evolved.

In contrast with these distant galaxies, stars orbiting on the outskirts of the Milky Way and other nearby galaxies move too fast for their velocities to result only from the gravity of gas and stars closer to the galactic center. If visible galactic matter is embedded in a cloud of invisible dark matter, though, gravity from the invisible matter can explain the high stellar velocities. Using stars’ orbital velocities in nearby galaxies as a reference, astronomers expected that stars in galaxies farther away would behave similarly. “Turns out that is not the case,” says study coauthor Stijn Wuyts of the University of Bath in England.

In other words, scientists at this moment really have no idea what causes the faster rotation in the outskirts of modern nearby galaxies.

Titan’s fizzy oceans?

New research suggests that the hydrocarbon lakes of Titan might periodically fizz with nitrogen bubbles.

A recent NASA-funded study has shown how the hydrocarbon lakes and seas of Saturn’s moon Titan might occasionally erupt with dramatic patches of bubbles.

For the study, researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, simulated the frigid surface conditions on Titan, finding that significant amounts of nitrogen can be dissolved in the extremely cold liquid methane that rains from the skies and collects in rivers, lakes and seas. They demonstrated that slight changes in temperature, air pressure or composition can cause the nitrogen to rapidly separate out of solution, like the fizz that results when opening a bottle of carbonated soda.

These results might help explain the mysterious islands that seem to appear and disappear and then reappear in Titan’s lakes. Rather than islands, they might be patches of nitrogen bubbles.

Minneapolis: another American city destroyed by Democrats

Link here. Democrats will see this as a partisan attack. It really isn’t. It is instead another attempt to point out the stark fact that the leftwing policies put forth by the Democratic Party in the past half century have been routinely disastrous.

But by 1988, then-mayor Donald Fraser—a member of the DFLP—had grown troubled by the stark contrast he saw between the majority of his city and who were thriving economically, and a number of African-American neighborhoods where crime, teenage pregnancy, and welfare dependency were experiencing a growth spurt. Taking a page out of the same playbook other big city Democrat mayors were using, Fraser believed that the cure was redistribution of income. He decided to revamp the way in which social-welfare expenditures were allocated and believed, specifically, that federal and local agencies needed to focus more of their resources on the economic problems confronting unwed mothers (who were disproportionately black) and their children.



Fraser’s successors as mayors of Minneapolis—Sharon Sayles Belton (1994-2001), R.T. Rybak (2002-2013), and Betsy Hodges (2014-present)—have shared this same core belief in the importance of massive public expenditures on social-welfare programs and wealth-redistribution initiatives.

The result has been disastrous. As of 2015, the poverty rate in Minneapolis was 25.3%, nearly twice the 14% statewide rate for Minnesota and the 14.3% rate for the United States as a whole. In 2010, a study of 142 metro areas in Minnesota found that only 15 bore a heavier property-tax burden than Minneapolis, and that was before the city raised its property taxes by 4.7% in 2011.

More recently, Minneapolis property taxes increased by 3.4% in 2016, and by a crippling 5.5% in 2017.

 Notwithstanding the growth in revenues generated by these taxes, the government of Minneapolis has been incapable of balancing its budget. In 2015, for example, the Minneapolis Public Housing Authority’s budget included $84 million in federal subsidies and grants. In 2017, the Metropolitan Council—which describes itself as “the regional policy-making body, planning agency, and provider of essential services for the Twin Cities metropolitan region”—received $91 million in federal funding. That same year, the Minneapolis Public Schools operated with a budget deficit of nearly $17 million.



This pattern has repeated itself throughout the United States. For the past half century almost every urban area has been dominated politically by Democrats. In that same time period, those urban areas have seen a distinct worsening of their economic situation. Even as these American cities have imposed a higher and higher tax burden on their successful citizens, they have seen higher and higher deficits. At the same time, poverty and economic failure has increased.

The important thing to note here is that the policies of the Democratic Party are a failure. Since that party seems incapable of changing those policies, it is essential that voters stop voting for it, either to force a change within that party or to remove that party from any position of power. Those are our choices, if we wish to improve the future of the United States.

House leans to less regulation of commercial space

During a hearing on March 8 of the House subcommittee on space the representatives overall pushed for less regulation of commercial space activities.

The overall problem was once again dealing with the Outer Space Treaty:

At a March 8 hearing of the subcommittee, members and witnesses grappled with the issue of how the government should oversee emerging commercial space activities in order to comply with obligations to the Outer Space Treaty, including whether such oversight is, in fact, required. Such “authorization and continuing supervision,” as specified in Article 6 of the treaty, is handled today by various agencies for commercial communications and remote sensing satellites and for launch. It’s less clear who would regulate new activities, ranging from commercial lunar landers to satellite servicing efforts, creating uncertainty in industry about who, if anyone, could provide that authorization and continuing supervision.

An April 2016 report delivered to Congress by the White House’s Office of Science and Technology Policy, required by Section 108 of the Commercial Space Launch Competitiveness Act of 2015, recommended what it called a “mission authorization” approach for providing that oversight. This approach would be modeled on the payload reviews performed by the Federal Aviation Administration during the launch licensing process, including an interagency review of proposed missions. While the mission authorization concept had won support from many in industry, as well as the FAA and some members of Congress, a change of administrations and its approach to regulation has emboldened some who want to limit industry regulation.

“Unfortunately, the Obama administration issued a report last year that called for expansive regulations over all types of private space activities,” said Rep. Lamar Smith (R-Texas), chairman of the House Science Committee, at the hearing. He cited a “crisis of overregulation” in general as a reason to oppose the previous administration’s proposal.

The House members and the witnesses apparently rejected the regulatory proposals that had been put forth by the Obama administration, and were instead searching for ways to limit the amount of regulation required under the Outer Space Treaty.

I say, dump the treaty. Nothing in it helps the development of space by private individuals or companies. Everything in it encourages bureaucracy and the limitation of private property.

SpaceX wins another Air Force launch contract

The competition heats up: SpaceX has been awarded a $96.5 million contract to launch an Air Force GPS satellite.

This price is about $14 million more than the last SpaceX Air Force launch contract. That’s probably because SpaceX was trying to undercut ULA’s price by as little as possible so that they could increase their profit. Until there are others in the business who can compete with SpaceX’s prices, the company is sitting pretty in any competitive bidding situation. Their costs are less, so they can always beat everyone else’s prices, while maximizing their profits.

Ukraine-Canadian partnership to launch from Nova Scotia

The competition heats up: A new launch company based in Canada and using a Ukrainian-made rocket called the Cyclone-4M has chosen as its launch site a location in Nova Scotia.

The rocket appears to be a variation of the Ukrainian Tsiklon-4 rocket, and would make this company competitive and in fact more capable than India’s smaller PSLV rocket that recently put 100 smallsats into orbit.

Engineer invents teabag dunking machine

Rube Goldberg lives! I don’t know why, but an engineer has invented a machine that can dunk his teabag automatically.

The teabag is hooked onto a crank and kept in position with a piston-like mechanism so that it’s moved up and down over a strategically-placed mug of hot water. The crank is mounted to copper tubing and chained to a five sprocket cassette that in turn is chained to the shaded-pole motor. Dunking starts when a switch is flicked.
