An evening pause: Normally I post things unrelated to space in my evening pauses, but this video describing the history of the development of the cameras that film rocket launches is too good to not post. Besides, every rocket launch is entertaining to watch, even those that fail.

The Cassini science team today released a mosaic of the last images Cassini took of Titan before it crashed into Saturn’s atmosphere four days layer.
The mosaic shows Titan’s north polar region, and shows seas, lakes, and spotty clouds. The lack of clouds is a puzzle to scientists, as they had expected the north polar region to be cloud-covered at this time as summer arrived there, as had been seen at the south pole.
During Titan’s southern summer, Cassini observed cloud activity over the south pole.
However, typical of observations taken during northern spring and summer, the view here reveals only a few small clouds. They appear as bright features just below the center of the mosaic, including a few above Ligeia Mare. “We expected more symmetry between the southern and northern summer,” said Elizabeth (“Zibi”) Turtle of the Johns Hopkins Applied Physics Lab and the Cassini Imaging Science Subsystem (ISS) team that captured the image. “In fact, atmospheric models predicted summer clouds over the northern latitudes several years ago. So, the fact that they still hadn’t appeared before the end of the mission is telling us something interesting about Titan’s methane cycle and weather.”
The truth is we haven’t the slightest idea whether the clouds over the south pole during its previous summer were normal or an aberration. We have barely seen a full year of seasons at Saturn and Titan. To confidently extrapolate any pattern from this slim data is silly.

Cool image time! The Lunar Reconnaissance Orbiter (LRO) science team this week released an image showing Wallach Crater as seen from the side. The image on the right is a section of that image and has been reduced to show here. The full image of 3.5-mile-wide crater and its surrounding terrain can be explored at the link. From the link:
Wallach crater (4.89°N, 32.27°E) formed within a thin layer of black basaltic lava flows that overlie much brighter anorthositic material. Think of a white cake with chocolate icing. When the asteroid (or comet) impacted this “iced cake”, ejecta from deeper portions (white cake, or rather brighter anorthosite) was thrown out onto the icing (darker basalt) resulting in intermediate tones where the two materials mixed.
The dark streaks seen inside the crater are blocks of the icing (basalt) breaking off and creeping down slope. The fact that the deepest material lands on top of the shallowest material (known as inverted stratigraphy) was first described by Gene Shoemaker from his pioneering observations at Meteor Crater, Arizona. This effect simplifies sampling the local geology in three dimensions. As an astronaut traverses towards the rim of a crater, the rocks underfoot come from deeper and deeper within the crater. The rocks at the rim are from the deepest portions of the crater!
It is especially interesting to use the viewer at the link to see the surrounding terrain, which includes two other craters that are far less distinct.
Two news stories today about two different suborbital rockets built by private companies:
The first story outlines the results from the August 25 test flight of SARGE.
The rocket reached an altitude of approximately 28 km. Launch and recovery took place at Spaceport America on August 25th, 2018. The rocket carried nine payloads. The flight demonstrated the SARGE system’s reusability when the vehicle was recovered with damage only to sacrificial components. The test also demonstrated the capability of the autonomous control system and validated the preflight vehicle integration process.
They have designed SARGE to fly up to 200 times, and then plan to sell it to the military which will use it as a target in its own tests.
The second story describes a suborbital launch yesterday at Spaceport America. This suborbital rocket carried three NASA experiments, the most interesting of which was the first test of a heat shield designed to open like an umbrella.
Made out of thickly woven and highly heat-resistant carbon fibers, supported by semi-rigid ribs, the ADEPT system fits into existing vehicle launch systems, but expands when separated from the rocket into a configuration that allows it to perform its mission.
The ADEPT model tested Wednesday spread to 30 inches in diameter after separation. Venkatapathy said a diameter of 75 to 80 feet would be required to deliver a crew of seven or so human explorers safely onto the surface of Mars, which has a lower gravity pull than Earth.
He said a thicker carbon weave and different dimensions would be needed to deliver scientific equipment to the surface of Venus, a planet with a gravity pull nearly as great as Earth’s, making approaches hotter and faster.
Even if neither of these companies ever scale up to orbital rockets, they signal the change in how NASA does things. In the past NASA built its own suborbital rockets. Now, they are using privately-built rockets, which allows for competition and more innovation.
This is basically the same transition NASA is undergoing in its commercial manned program, going from being the sole builder and designer of spacecraft, enforced by a government-imposed monopoly, to merely a customer buying spacecraft from many private builders. It is a transition that can only generate good results in the future.
The dress rehearsal of Hayabusa-2’s eventual landing on the asteroid Ryugu was cut short yesterday when the spacecraft found it could not get a reliable distance reading of the surface once it descended to 600 meters.
The problem was apparently due to the pitch black surface of the carbon-rich asteroid that made laser distance measurements difficult. JAXA says the Hayabusa 2 is in good condition, and the agency is considering changing landing procedures such as adjusting the configuration of measuring devices.
Despite the suspension, the altitude of 600 meters the explorer has descended to the asteroid is the closest ever recorded. JAXA had planned to bring down the probe to 30 meters and make detailed observations of a landing spot.
Just to clarify, this was a height record for Hayabusa-2 only.
The replicators are coming! HP has announced that it plans to mass produce a large 3D metal printer that can be used by large industrial manufacturers.
Each Metal Jet production machine will cost less than US$400,000, and will give you a maximum build volume of 430 x 320 x 200 mm (16.9 x 12.6 x 7.9 inches).
HP is timetabling the Metal Jet roadmap in stages. Right now, it’s already operational in two pilot programs. Metal injection molding specialist Parmatech is using it to produce medical equipment like surgical scissors and endoscopic surgical jaws, and GKN Powder Metallurgy is producing parts for automotive and industrial giants like Volkswagen and Wilo.
In 2019, HP will start up a production service, which will allow manufacturers to upload 3D design files and have them printed out in industrial quantities by Parmatech and GKN. The printers themselves will begin shipping in 2020, with “broad availability in 2021.” Desktop Metal, for its part, has pushed back availability of its production machines from this year to 2019.
HP is not the first to do this, but this appears to be the largest-scale production attempt.
The wonders of science: Astronomers have successfully used the faint radio emissions from very distant galaxy to roughly determine the shape and size of a nearby asteroid.
In an unusual observation, astronomers used the National Science Foundation’s Very Long Baseline Array (VLBA) to study the effects on radio waves coming from a distant radio galaxy when an asteroid in our Solar System passed in front of the galaxy. The observation allowed them to measure the size of the asteroid, gain new information about its shape, and greatly improve the accuracy with which its orbital path can be calculated.
When the asteroid passed in front of the galaxy, radio waves coming from the galaxy were slightly bent around the asteroid’s edge, in a process called diffraction. As these waves interacted with each other, they produced a circular pattern of stronger and weaker waves, similar to the patterns of bright and dark circles produced in terrestrial laboratory experiments with light waves. “By analyzing the patterns of the diffracted radio waves during this event, we were able to learn much about the asteroid, including its size and precise position, and to get some valuable clues about its shape,” said Jorma Harju, of the University of Helsinki in Finland.
The amount of information is not great, and there is an enormous amount of uncertainty in the data. Nonetheless, this is an amazing and fascinating observation.
Story here. From the link:
The issue may be related to Mercury (the metal, not the planet). On a tip from a science journalist friend who covers telescopes and who has been there, I verified the observatory uses a vat of liquid mercury as a float bearing for the giant solar telescope. According to an internal NSO/NMSU document, that bearing is “high-risk” during maintenance. If there was a major mercury spill, it might explain why the Feds are there, with FBI providing security. The amount of Mercury is said to be in the “tens of gallons” range, which is next to impossible to come by in the commercial market these days, and if it were weaponized, it would make a very nasty dirty bomb. Perhaps there’s some security issue with the mercury on-site.
This is third hand, so it should be taken with a great deal of skepticism.
NASA has rearranged its listening plans for the rover Opportunity so that it will extend into the dust devil season beginning in November.
The science team is also sending a command three times a week to elicit a beep if the rover happens to be awake, and will soon be expanding the commanding to include “sweep and beeps” to address a possible complexity with certain conditions within the mission clock fault. These will continue through January of 2019.
The dust storm on Mars continues its decay with atmospheric opacity (tau) over the rover site continuing to decrease. Once the tau has fallen below an estimated measurement of 1.5 twice – with one week apart between measurements – a period of 45 days will begin representing the best time for us to hear from the rover.
This also represents the best time to attempt active commanding during a specific mission clock fault condition. Back during the attempted recovery of the Spirit rover, a technical issue required the team to actively command the rover to communicate. Opportunity has no such issue; if we hear from it, it will likely be from listening passively as we have been, and as we will continue to do through January.
We will also actively attempt to command the rover to communicate during the 45-day listening period to cover the clock fault condition. After that, we will report to NASA on our efforts.
In other words, the final 45 day listening period will not officially begin until the Martian atmosphere has cleared more, rather than begin about now and thus end about the middle of November, before the dust devil season begins.
The reasons they want to listen through the dust devil season is that they believe it likely that the rover’s solar panels have been covered with dust, and will need a nearby dust devil to blow this away. This might sound unlikely, but it has happened several times with both Spirit and Opportunity during both of their spectacularly extended missions.
NASA today successfully completed the last parachute test using an Orion test vehicle.
Two quotes tell us all we need to know:
“Orion is our new human exploration spacecraft, and this is a spacecraft that will take people farther in space than we’ve ever gone before,” said [Orion project manager Mark Kirasich].
…This parachute test is the last one for Orion after a decade of development, Kirasich said.
NASA is once again lying about Orion’s capabilities. It will not “take people farther in space than we’ve ever gone before.” It will be able to take humans to the Moon, which is somewhere Americans have been (just in case Kirasich has forgotten.) Beyond that it is totally insufficient for interplanetary flight. It will, on its own, never take anyone anywhere beyond that, and even if it does go beyond lunar orbit, it will do so merely as the return capsule that is part of a much larger vessel.
Secondly, that it took ten years to complete the parachute system for this capsule is truly a joke. The Dragon cargo capsule was built by SpaceX in less than four years. Its manned version could have launched after only two years of work had NASA bureaucrats and Congressional cheapness not gotten in the way. Boeing’s Starliner parachute system was also built in about half that time, and would have been finished sooner had not NASA bureaucrats demanded extra tests, for reasons that have never been made clear.
NASA says it will be launching the first Orion mission to the Moon in 2022, followed by the first Gateway mission in 2024. I am predicting that while the first date might be met (only seven years behind schedule), the second will not. Do not expect the first module to head for the Moon for at least a decade.

Scientists have identified a molecule produced by the body during fasting that then acts to delay aging.
In this study, the research team explores the link between calorie restriction (eating less or fasting) and delaying aging, which is unknown and has been poorly studied. The findings are published in the journal Molecular Cell.
The researchers identified an important, small molecule that is produced during fasting or calorie restriction conditions. The molecule, β-Hydroxybutyrate, is one type of a ketone body, or a water-soluble molecule that contains a ketone group and is produced by the liver from fatty acids during periods of low food intake, carbohydrate restrictive diets, starvation and prolonged intense exercise.
“We found this compound, β-Hydroxybutyrate, can delay vascular aging,” Zou said. “That’s actually providing a chemical link between calorie restriction and fasting and the anti-aging effect. This compound can delay vascular aging through endothelial cells, which line the interior surface of blood vessels and lymphatic vessels. It can prevent one type of cell aging called senescence, or cellular aging.”
Senescent cells can no longer multiple and divide. The researchers found β-Hydroxybutyrate can promote cell division and prevent these cells from becoming old. Because this molecule is produced during calorie restriction or fasting, when people overeat or become obese this molecule is possibly suppressed, which would accelerate aging.
It appears that there is still a lot of work to create an artificially produced version of this molecule, but to know it exists is a significant discovery. For the body to produce it requires you to fast for at least 24 hours.
They’re coming for you next: The level of hatred and insanity coming from the partisan left has in the past two years steadily moved from mere vicious hyperbole to increasing violence. The upcoming midterm elections is now fueling this increase in violence, as seen by these stories from yesterday:
The first two stories were generated mostly by Twitter threats, a sewer of such vicious evil. They might not result in violence, but such leftist threats on Twitter are definitely becoming more common. And interestingly, even as Twitter is shutting down conservative speech it seems to have little problem with death threats against conservatives.
The third story however is more worrisome. It is part of a pattern where the insane over-the-top statements by Democratic Party elected officials is fueling a hatred among those who are less than stable themselves, resulting in acts of violence. Nor is this the only story recently where an unstable person attacked something or someone because they were perceived as conservative.
And the craziness on the left shows no signs of letting up, as indicated by the decision of leftist Las Vegas professor to shoot himself in the arm “in protest of President Donald Trump.” Though I have no evidence to support this theory, it appears to me from the story that he might have planned on suicide, but chickened out.
I am very worried that in the next two months we will see at least one attack against Republicans similar to the attempted mass murder last year of Republican congressmen at a charity baseball practice. In fact, I fear that such violence is almost certain.
Capitalism in space: Blue Origin has now delayed the first manned flights on its New Shepard suborbital spacecraft into 2019.
They had said they would be doing manned test flights before the end of 2018, but these flights have not happened, and now they admit that they will be delayed until 2019.
Overall, the lack of test flights in 2018 is somewhat puzzling. They have a spacecraft that is built on a design that previously flew multiple times. Why should the second craft have problems causing such delays?
NASA has released an updated plan for building FLOP-G, now officially dubbed “The Gateway.”
The article provides a bunch of NASA’s typical powerpoint slides, detailing when they want to do what, with the first Gateway module launched in 2022 and the first manned mission to it in 2024.
None of this will happen as they wish, however, because NASA can’t build anything on schedule or on time. Also, there is this key detail, mentioned merely as an aside in the article: “A commitment of funding for the gateway project is still forthcoming.”
Congress has not yet funded this. Unfortunately, I expect them to do so, but I also expect that none of the funds will ever be sufficient, and that the project will drag on and on, for years on end, with little accomplished, at least by NASA.
The plan as outlined does incorporate the use of commercial vendors to supply cargo. In the end, I expect this component to be the only thing ready and able to fly, when needed.
The blacklist lives! New research has confirmed that the bulk of American universities are dominated by liberal and Democratic professors, with many having zero conservatives or Republicans in their facility.
The political registration of full-time, Ph.D.-holding professors in top-tier liberal arts colleges is overwhelmingly Democratic. Indeed, faculty political affiliations at 39 percent of the colleges in my sample are Republican free—having zero Republicans. The political registration in most of the remaining 61 percent, with a few important exceptions, is slightly more than zero percent but nevertheless absurdly skewed against Republican affiliation and in favor of Democratic affiliation. Thus, 78.2 percent of the academic departments in my sample have either zero Republicans, or so few as to make no difference.
My sample of 8,688 tenure track, Ph.D.–holding professors from fifty-one of the sixty-six top ranked liberal arts colleges in the U.S. News 2017 report consists of 5,197, or 59.8 percent, who are registered either Republican or Democrat. The mean Democratic-to-Republican ratio (D:R) across the sample is 10.4:1, but because of an anomaly in the definition of what constitutes a liberal arts college in the U.S. News survey, I include two military colleges, West Point and Annapolis.1 If these are excluded, the D:R ratio is a whopping 12.7:1.
Political homogeneity is problematic because it biases research and teaching and reduces academic credibility.
Just to make it clear, the ratio of Democrat to Republican averages 13 to 1, if you exclude the two military colleges. This can only be occurring if the facility at American colleges is making a conscious effort to exclude conservatives or Republicans. Or to put it more bluntly, to blacklist anyone who dares express a dissenting view.
The article has some good information however about the handful of universities that do have diversity of thought in the facility.
The two military colleges in my sample, West Point and Annapolis, have D:R ratios of 1.3:1 and 2.3:1. Although it is debatable whether military colleges are liberal arts colleges, U.S. News’s inclusion of them in the liberal arts category is fortuitous because they offer evidence that when colleges provide supportive environments, intellectual diversity is achievable. There are other exceptions, such as Claremont McKenna, which adopted a viewpoint diversity strategy early in its history, and Kenyon, which is one of a few of the top-ranked liberal arts colleges located in a predominantly Republican state and which did not become coed until 1969.
Thomas Aquinas and St. John’s, another college with above average Republican representation, have emphasized interdisciplinary teaching and downplayed the publish or perish imperative, which [other researchers] have argued contributes to left-oriented groupthink.
These are the colleges every parent and teenager should consider as the place to go. Everywhere else is crap, and should be avoided like the plague.
It is definitely worth reading the entire article, which also includes breakdowns by disciplines, and finds the blacklisting to be especially egregious in the humanities.

On this day, September 11th, it is worthwhile taking this glimpse at what the American dream stood for, and still stands for — gentle love and allowing each person to follow their dreams to do wonderful things — versus those other extremist ideologies that brook no dissent and have killed thousands, on this day as well as before and after.
Most people are very aware of Mars’ giant volcanoes. This week the science team for Mars Reconnaissance Orbiter (MRO) decided to highlight instead a location on Mars filled with relatively tiny volcanoes. The image on the right is only one small section from the full image, and shows some of these pitted cones, as well the strange nearby badlands. From their caption:
The origins of these pitted mounds or cratered cones are uncertain. They could be the result of the interaction of lava and water, or perhaps formed from the eruption of hot mud originating from beneath the surface.
These features are very interesting to scientists who study Mars, especially to those involved in the ExoMars Trace Gas Orbiter mission. If these mounds are indeed mud–related, they may be one of the long sought after sources for transient methane on Mars.
The age of these pitted cones is not known. They might be still active, or have sat on Mars unchanged for eons.
As always, context is crucial for gaining a better understanding of what we are looking at. The map on the right shows that these particular cones, indicated by the white cross, are located in an area of those plains dubbed Chryse Planitia, part of the vast northern plains of Mars, an area where some scientists think an intermittent ocean might have once existed. As you can see, this is also the region that took most of the apparent drainage running off the slopes of the planet’s giant volcanoes.
Nor are these cones unique in this region. MRO has taken a good scattering of images at this general location (41 degrees north, 332 degrees east), and throughout the surrounding terrain are many more of these pitted cones.
If these cones are a source of the transient methane on Mars, then the Trace Gas Orbiter should eventually see a concentration of methane above them. This would not prove them to be the source, but it would make them a much more intriguing target for a later rover mission.
Couldn’t happen to a nicer college: The enrollment in the freshman class at Evergreen State College is down 50% since to the college’s takeover by leftist thugs two years ago.
This fall, we expect less than 300 freshmen to attend Evergreen, a fifty percent drop from two years ago. It is the only four year institution in the state of Washington that has seen a decrease in applications, and is currently publicly funded for 4200 students, far greater than this year’s anticipated total attending class of 2800.
This decline at Evergreen is in contrast to an increase in enrollment at competing Washington state colleges. And expect things to become worse for Evergreen, since it has taken no actions to change its leftist indoctrination bent, as noted by one professor at the college:
Advocacy and activism rather than the pursuit of truth and knowledge is being promoted as a way of recruiting desperately needed new students (In 2011 Evergreen changed its official mission statement to read: “Evergreen supports and benefits from a local and global commitment to social justice”). Bringing in new faculty or guest speakers with conservative or centrist political perspectives is considered risky and out of the question at the moment. Fear and self-censorship is pervasive among Evergreen faculty, especially under the existing budget crisis. An “independent” External Review Panel exonerated the president and administrators while blaming Evergreen’s woes on Bret Weinstein and ‘alt-right’ agitators prompted one journalist to ask, “Who Will the Evergreen Mob Target Next?”
The best thing that could happen would be for this college, as well as many others, to shut down. They no longer teach, but act instead as leftist and Democratic Party propaganda machines.
Capitalism in space? Arianespace yesterday signed its first commercial contract for its new rocket, Ariane 6.
The Sept. 10 contract is Arianespace’s first with a commercial satellite operator for Ariane 6, and brings to eight the number of Ariane 6 missions on the company’s manifest, assuming none of the Eutelsat satellites are dual-manifested on the same rocket.
Eutelsat executives have suggested for years that the company was willing to be first in line to embrace Ariane 6, including most recently in June 2017 when the company signed a three-launch agreement for Ariane 5 missions.
Eutelsat spokesperson Marie-Sophie Ecuer told SpaceNews by email that the multi-launch agreement came with “attractive terms” that are “fully aligned with our objective to significantly reduce launch cost,” but declined to say if the company received a discount. To woo customers, SpaceX offered discounts of around $10 million to launch on the first Falcon 9 rockets to use previously flown first-stage boosters.
I question the private nature of this deal, in that Eutelsat is a European company with many legal ties to the European Union. Since all reports I’ve seen suggest that Ariane 6 is not going to be as cheap as SpaceX’s rockets, I wonder if some political pressure has been applied to Eutelsat to sign this contract.
Overall, it increasingly appears to me that Ariane 6 will not get much business outside of Europe because of its cost. Much like Russia, Europe is giving up on its commercial international market share, mainly because it can’t or won’t compete with the newer American companies.
The faulty and spongy concrete that the Russians have discovered at the Vostochny Soyuz launchpad was caused when the contractor hurried the job as well as improperly laid the concrete.
“It was a mistake by the contractor Spetsstroi. The process of concrete laying was violated due to rush work,” the source said. “Spetsstroi laid the concrete in winter time in utterly unsuitable conditions and used drying fans.” The source said the cavities in concrete were identified more than a year and “continued to be eliminated by the public corporation itself until the contract with Adonis was concluded.
Part of the blame here falls not to the contractor but to Putin. He demanded that Roscosmos complete a launch at Vostochny in 2016, and to do so all the contractors at Vostochny had to scramble to get the job done. Apparently, this particular contractor was forced to cut corners improperly.
The new colonial movement: India’s space agency ISRO this week unveiled the spacesuit it is designing for the Gaganyaam manned mission scheduled for 2022.
The new space-suit mentioned above has been developed by ISRO at its Vikram Sarabhai Space Centre over the last two years. ISRO showcased the space suit for the Gaganyaan crew at the Bengaluru Space Expo for the first time ever. As per reports, ISRO has developed two of such space suits to date and will also develop a third one prior to the testing of the manned mission in 2022. The space suit comes with a capacity of one oxygen cylinder that claims to hold enough oxygen for 60 minutes.
This suit is not being built for spacewalks, but as a backup should the spacecraft itself develop a leak.
The National Solar Observatory facility at Sacramento Peak in New Mexico, managed by a consortium of universities, has been shut down temporarily for unstated security reasons.
The Sunspot Observatory is temporarily closed due to a security issue at the facility that’s located 17 miles south of Cloudcroft in the Sacramento Mountains Friday, an Association of Universities for Research in Astronomy (AURA) spokeswoman Shari Lifson said.
“The Association of Universities for Research in Astronomy who manages the facility is addressing a security issue at this time,” Lifson said. “We have decided to vacate the facility at this time as precautionary measure. It was our decision to evacuate the facility.”
She said she cannot comment on the specifics of the security issue.
This is a very strange story, especially because of the lack of information being released. What could have happened that required them to evacuate? And why can’t they release more details?
I can’t deny that my first thought was aliens, but this is a laughable and ridiculous idea. The facility merely looks up at the Sun, and is also a somewhat minor research facility. More likely they have had a serious employee problem, and are trying to take steps to prevent anyone from getting hurt.
Worlds without end! A paper published August 29 in the science journal Icarus has hurled serious criticisms of the definition of planets imposed on the world by International Astronomical Union in 2006 that also robbed Pluto of planetary status.
“The IAU’s definition was erroneous since the literature review showed that clearing orbit is not a standard that is used for distinguishing asteroids from planets, as the IAU claimed when crafting the 2006 definition of planets,” said Dr. Kirby Runyon, from the Johns Hopkins University Applied Physics Laboratory. “We showed that this is a false historical claim. It is therefore fallacious to apply the same reasoning to Pluto.”
According to the team, the definition of a planet should be based on its intrinsic properties, rather than ones that can change, such as the dynamics of a planet’s orbit. “Dynamics are not constant, they are constantly changing. So, they are not the fundamental description of a body, they are just the occupation of a body at a current era,” Dr. Metzger said. “We recommend classifying a planet based on if it is large enough that its gravity allows it to become spherical in shape.”
I must also note that the IAU’s definition had ignored the recommendations of its own committee on coming up with a new planetary definition and was voted on at the very end of a conference when almost everyone had left.
In other words, the IAU’s actions in 2006 were purely political, were bad science, and should be dumped as quickly as possible. And now the scientists are saying this, in peer-reviewed papers.
As part of its hard-nosed approach to PLO intransigence, the Trump administration has decided to shut down the Palestinian offices in DC.
National security adviser John Bolton is expected to announced Monday that the U.S. will shutter the Palestine Liberation Organization’s (PLO) office in Washington, D.C., The Wall Street Journal reported. “The Trump administration will not keep the office open when the Palestinians refuse to start direct and meaningful negotiations with Israel,” Bolton is expected to say, according to a draft of his speech reviewed by The Wall Street Journal.
This is on top of cutting off all U.S. funding to the PLO.
Though I like this decision, as it ends U.S. support for these terrorist organizations, I doubt it will do anything to change PLO policy. The petty dictators who are in charge of Palestinian affairs, the PLO and Hamas, require the selling of hatred of Jews and Israel to survive. Everything else they have done has bankrupted the lives of the people living in the West Bank and Gaza. The second they change their tune, the people there might suddenly realize how bad their leadership is, and could very well string them up, much as the Italians did to Mussolini at the end of World War II.
Two stories out of Russia today suggest that the serious quality control problems plaguing its aerospace industry have not been brought under control.
According to the second article the launch delay is because a Russian satellite manufacturer is behind schedule and might not deliver needed parts for the satellite’s assembly in time. I suspect the delay might also be related to the first article, as this satellite will launch on the brand new launchpad where they have discovered the cavities below ground.
That these cavities were not pinpointed during construction is very troublesome. One of the reasons SpaceX’s Boca Chica launchsite in Texas is taking as long as it is getting built is that the company had to make sure the soft beach property was structurally sound for rocket launches. That the Russians missed this speaks poorly again of their quality control.
Delays are common in the rocket industry, but in the context of Russia’s other space-related problems, the delay suggests a wider problem.
Capitalism in space: SpaceX last night successfully launched a communications satellite as well as recovered the Falcon 9 first stage.
The biggest news here is how routine the landings of the first stage have become, getting its first mention eight paragraphs into the article above, with its landing described almost as an aside. This was a new Block 5 first stage, and it will likely fly again within a relatively short period of time.
The leaders in the 2018 launch race:
24 China
16 SpaceX
8 Russia
6 ULA
5 Arianespace (Europe)
China still leads the U.S. in the national rankings, 24 to 23.
I should have posted this earlier, but I am acting as a quickly scheduled emergency guest for Coast to Coast with Connie Willis tonight, from 10 to 11 pm (Pacific). Should be fun.
