Republican wins special election in black/Hispanic district in Texas

Is this significant? A Republican today won a special election for a Texas state senate seat in a predominately black and Hispanic district that was won by Hillary Clinton by 12% and hasn’t been held by a Republican for more than a hundred years.

It is dangerous to extrapolate the results from a single state legislative district to the wider nation. Nonetheless, for a Republican to win such a seat in a district whose two biggest demographics are Hispanic and black suggests we might yet see a historic shift this coming election. If the Democrats can no longer depend on these voters, they will find it difficult to win any national elections.

Vulcan found?

Scientists have found a super-earth orbiting 40 Eridani-A, a star located sixteen light years away and proposed by Gene Roddenberry in 1991 as the home star for his race of logical Vulcans.

It turns out the letter authors’ prediction was right — a world really does orbit the primary star of the three-star 40 Eridani system. (Whether it’s home to a logic-based alien society, though, is anyone’s guess!)

The world is a super-Earth, the most common type of planet in the galaxy (though a type that’s missing from our solar system). At twice Earth’s radius and eight to nine times its mass, 40 Eridani b sits on the line that divides rocky super-Earths from gaseous ones. The planet orbits its star every 42 days, putting just inside the system’s habitable zone — in other words, where it’s nice and hot. At 16 light-years away, it’s the closest super-Earth known and therefore a good potential target for followup observations.

The discovery was made by a survey taking place using a relatively small telescope right here in the Tucson area, on top of Mount Lemmon. Most cool!

Instrument on GRACE-FO fails

The U.S/German science two-satellite constellation, launched in May, has not gathered any science data since July because one instrument on one satellite has shut down.

It appears the problem is related to an electrical problem. The article provides little information, though they say they will switch to a back up system later this month. I wonder why this has taken so long.

The article at the link calls this “a glitch.” That is a lie and bad journalism. Any failure that shuts down a spacecraft for months and requires the use of a back up is a major failure, not a mere “glitch.” I wish news organizations would stop using that word, as it only exists to help minimize the seriousness of a problem.

Air Force estimates Space Force cost at $13 billion for first 5 years

Pork! Air Force has now released its first estimate for establishing a Space Force, with an estimated cost of $13 billion for first five years.

A copy of the Air Force memo was obtained Monday by The Associated Press. The memo says the first-year cost of a Space Force would be $3.3 billion, and the cost over five years would be an estimated $12.9 billion.

As I have said, this is nothing more than pork. At this stage all that needs to happen is a reorganization that would put all space activities in a single office in the Air Force. This is also what the Air Force has wanted to do. Creating a whole new military branch at this time is overkill, and will merely result in too much bureaucracy, for only one reason, to spend money.

Kenya creates space agency

The new colonial movement: Kenya today announced the official establishment of its own space agency, the Kenya Space Agency Board (KSAB).

KSAB was established by President Uhuru Kenyatta through a March 2017 gazette notice and will be headed by the Kenya Defence Forces’ Major General (Rtd) James Aruasa.

The array of KSAB’s responsibilities include co-ordinating space-related activities, recommending national space policies and establishing centres of excellence in space science.

It appears to me that there a power struggle is going on in Kenya over space, with the wrong people winning. A university team recently built the nation’s first cubesat, getting it launched as a secondary payload. This space board however seems entirely run by the government and its military. I fear that this turf war is going to squelch any future Kenyan space development.

Curiosity fails again to drill into Vera Rubin Ridge

For the third time Curiosity has failed to drill into the rock on top of Vera Rubin Ridge.

Last night we learned that our drill attempt on “Inverness” was not successful, reaching only 4 mm into the rock.

The only successful drill attempt on the ridge occurred when they moved down off the top of the ridge to a slightly lower geological layer.

They are moving Curiosity to another candidate drill site on the ridge, where they will try again. While they imply in their reports that it is solely the hardness of the ground that is stopping them, I still wonder if the improvised drill technique, using the robot arm to push down rather than the drill’s jammed feed mechanism, is partly to blame. I would think that they have placed limits on how hard the arm can push to protect it.

A Trip Through Victorian Paris, France

An evening pause: This footage was taken from 1896 to 1900 in Paris, and has been cleaned up and shown here at the correct speed with sound added to match the visuals. What you will see:

0:08 – Notre-Dame Cathedral (1896)
0:58 – Alma Bridge (1900)
1:37 – Avenue des Champs-Élysées (1899)
2:33 – Place de la Concorde (1897)
3:24 – Passing of a fire brigade (1897)
3:58 – Tuileries Garden (1896)
4:48 – Moving walkway at the Paris Exposition (1900)
5:24 – The Eiffel Tower from the Rives de la Seine à Paris (1897)

What strikes me is the dignified behavior and dress of the people. We are of course mostly looking at Paris’s high class streets, but nonetheless there is something in the culture that requires them to behave as civilized as they can.

Trump unclassifies FISA warrants, interviews; orders release of unredacted FBI text messages

Trump has today unclassified both the FISA Carter Page application and the FBI interviews connected with that application. He also ordered the release, unredacted, of all FBI text messages of James Comey, Andrew McCabe, Peter Strzok, Lisa Page, and Bruce Ohr.

This information I think is going to demonstrate that the certain people at the FBI have been running an anti-Trump/pro-Democratic Party operation, concocting a false claim of Russian-Trump collusion in order to remove a duly elected President. Moreover, comparing the previously released redacted text messages with the unredacted messages is almost certainly going to reveal that someone at the FBI has acting to obstruct the investigation.

I wonder if anyone will ask the question “Who?”

I should also point out that Trump himself could have read these documents whenever he wanted. He doesn’t need to declassify them to see them, and form judgements from them. Moreover, the redactions only apply to the public, not to Trump. He could have seen this anytime, and acted immediately, if he had chosen.

Instead, he chose to wait and wait, and then release this now, at a moment when all eyes are aimed at the fake scandal being perpetrated by the Democrats against his Supreme Court nominee.

Cryo-volcanism had less influence on shaping Ceres than predicted

The uncertainty of science: A careful analysis of the Dawn data has found that though cryo-volcanism has occurred repeatedly on Ceres, it had less influence on the dwarf planet’s surface than previous models had predicted.

At the same time, the data also suggests that Ceres has been more active throughout its history than predicted. They found about 22 domes that are apparently past cryo-volcanoes that have flattened out.

“Given how small Ceres is, and how quickly it cooled off after its formation, it would be exciting to identify only one or two possible cryovolcanoes on the surface. To identify a large population of features that may be cryovolcanoes would suggest a long history of volcanism extending up to nearly the present day, which is tremendously exciting,” said Sizemore. “Ceres is a little world that ought to be ‘dead,’ but these new results suggest it might not be. Seeing so much potential evidence for cryovolcanism on Ceres also lends more weight to discussions of cryovolcanic processes on larger icy moons in the outer solar system, where it’s likely more vigorous.”

Statement about closure of solar observatory

AURA, the university consortium that operates the closed Sunspot Solar Observatory in New Mexico, issued a statement today about that closure.

AURA has been cooperating with an on-going law enforcement investigation of criminal activity that occurred at Sacramento Peak. During this time, we became concerned that a suspect in the investigation potentially posed a threat to the safety of local staff and residents. For this reason, AURA temporarily vacated the facility and ceased science activities at this location.

The decision to vacate was based on the logistical challenges associated with protecting personnel at such a remote location, and the need for expeditious response to the potential threat. AURA determined that moving the small number of on-site staff and residents off the mountain was the most prudent and effective action to ensure their safety.

In light of recent developments in the investigation, we have determined there is no risk to staff, and Sunspot Solar Observatory is transitioning back to regular operations as of September 17th. Given the significant amount of publicity the temporary closure has generated, and the consequent expectation of an unusual number of visitors to the site, we are temporarily engaging a security service while the facility returns to a normal working environment.

We recognize that the lack of communications while the facility was vacated was concerning and frustrating for some. However, our desire to provide additional information had to be balanced against the risk that, if spread at the time, the news would alert the suspect and impede the law enforcement investigation. That was a risk we could not take.

This news release, while still very vague about the criminal investigation, implies that there was a dangerous criminal suspect on the mountain that federal officials were pursuing, and they evacuated to protect their employees.

This explanation still leaves serious questions. Why for example were local police kept in the dark about this investigation? It makes no sense not to include them, unless they might be a target of the investigation, something that in this case does not appear to be true.

Also, if there was a criminal on the mountain, secrecy is not really an effective way to catch him. It might make sense, but they have not provided us any information that would explain this.

Multiple launches today

Two launches today:

  • ULA’s last Delta 2 rocket launches ICESat-2 icecap tracking satellite for NASA
  • Indian’s PSLV rocket launches two British satellites

More details about ICESat-2 can be found here.

The PSLV launch raises India’s 2018 launch total to 4, tying Japan. The leaders in the 2018 launch standings:

24 China
16 SpaceX
8 Russia
7 ULA
5 Europe (Arianespace)

The U.S. and China are once again tied at 24 each.

Russians considering spacewalk as part of airleak investigation

The Russians are now considering having their astronauts on ISS do a spacewalk to inspect the outside of the Soyuz capsule for evidence of sealant work at the location of the drill hole that caused the airleak.

If the spacewalk is attempted, the cosmonauts would have to get to the Habitation Module, peel off soft thermal layers blanketing the spacecraft and then cut through the meteoroid shielding bordering this section of the spacecraft at a distance of around 1.5 centimeters from its pressurized hull.

To access the area of the hole on the exterior of the Soyuz, Russian officials are developing a spacewalk scenario relying on the available Strela boom, GStM. The telescopic device can be used to carry a cosmonaut secured to a special anchor at the end of the boom to a location aboard the station otherwise inaccessible to spacewalkers due to lack of railings.

The spacewalk would take place sometime in November or December. The goal is to help confirm that the sealant work was done on the ground, as well as help pinpoint when.

Soyuz capsule was drilled after it was fully assembled

The investigation into the drillhole leak in the Soyuz capsule docked to ISS has revealed that it had to have been done after the capsule was fully assembled.

“During the analysis of those images, traces of drilling were found on the anti-meteorite shield,” the source said, adding that “the top of the drill came through the pressure hull and hit the non-gastight outer shell.”

According to another industry source, the non-gastight anti-meteorite protection is installed right before the spacecraft is taken to the final assembly workshop. “When Soyuz MS-09 has just arrived to the final assembly workshop, it was photographed in details. No hole and no signs of drilling… were found. The spacecraft was drilled later, when it was fully assembled,” the source said. He added that the anti-meteorite shield was also photographed before being installed, and no traces on it were found as well.

The source suggested that the spacecraft could be damaged either during the very last stage of works or during its 90-day stay in the checkout stand, adding that it was highly unlikely that the damage occurred during the transportation to the Baikonur space center in Kazakhstan or at the launch facility.

This narrowing of the time frame for the drilling will increase the chances that the Russians will be able to identify who did.

Republican Congress boosts NIH spending, rejecting Trump proposed cuts

Failure theater: The Republicans in Congress have given the NIH a significant boost in spending, rejecting both Trump’s proposed cuts and reorganization proposals.

Congress has approved a $2 billion raise, to $39.1 billion, for the National Institutes of Health (NIH) in a 2019 spending bill approved by House of Representatives and Senate negotiators last night.

As expected, the 5% boost matches the Senate’s proposed spending level and surpasses a $1.25 billion increase in a draft bill passed by the House. President Donald Trump’s administration had requested $34.8 billion for the fiscal year that begins 1 October. This is the fourth year in a row that NIH has received a substantial increase, after more than a decade of flat budgets.

Trump had also proposed shifting three Health & Human Service agencies into NIH. Congress ignored this.

This illustrates the bankrupt nature of the Republicans in Congress. Don’t believe them when they argue they want to limit government. They are lying. They pass tax cuts to make you happy and vote for them, then turn around and pour money we don’t have at their Washington friends.

This also illustrates the bankrupt nature of the American voter. We gobble up tax cuts, either ignore or celebrate Congress’s out-of-control spending, and then vote for the elected officials who do this.

SpaceX to name on Monday its first customer for BFR flight around Moon

Capitalism in space: In a tweet SpaceX announced that it will name on Monday its first customer for flight around Moon, using its Big Falcon Rocket rather than the Falcon Heavy as previously announced.

There will be a lot of speculation over the next few days, but we must remember that the BFR is years away from launch, so nothing here is either set in concrete, nor even likely to happen.

Luxembourg formally establishes space agency

The new colonial movement: Luxembourg this week formally established its space agency, along with a fund to back new commercial space companies.

Unlike traditional national space agencies, which support spacecraft missions and scientific research, the Luxembourg Space Agency will focus primarily on building up the country’s space industry as well as supporting education and workforce development.

Schneider noted that Luxembourg’s recent efforts, most notably the SpaceResources.lu project to attract companies working in the nascent space resources field, had led to 20 countries establishing a presence in the country. “All this is why it’s so important to me to launch today this Luxembourg Space Agency in order to professionalize our approach to this new community,” he said.

Serres said that the agency will work with a wide range of other organizations, both within the government and the private sector, to meet the agency’s goals. “The agency will be well-equipped to support industry in their daily challenges, and it leads to the most favorable environment for this sector to continue to grow,” he said, describing its four “strategic lines” as expertise, innovation, skills and funding.

That last item will include a new fund for supporting space companies. Schneider announced that the space agency will work with other government agencies and the private sector to establish the Luxembourg Space Fund, valued at 100 million euros ($116 million). The fund, according to a government statement, will “provide equity funding for new space companies with ground-breaking ideas and technology.”

Only part of the new fund will involve government money. “It will be a public-private partnership, where the government will take a share of 30 to 40 percent,” Schneider said.

The agency’s entire work force will be about 12 people, since its focus will be attracting private space companies to come to Luxembourg.

NASA & Roscosmos heads to meet

After their teleconference to discuss the status of Russia’s investigation into the airleak on ISS, the heads of NASA and Roscosmos agreed to their first face-to-face meeting on October 10 at the Baikonur spaceport in Kazakhstan.

Part of the reason for the teleconference and this announcement to try to stem the wild rumors about the leak, including the accusation that it was done by an American astronaut.

I also expect them to discuss how they can jointly lobby the American Congress to fund the Gateway boondoggle, formerly (F)LOP-G.

Cassini’s last view of Titan

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.

Oblique view of lunar crater

Wallach Crater

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.

More suborbital private rockets in the news

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.

Dress rehearsal of Hayabusa-2’s landing scrapped

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.

HP to mass produce large 3D metal printers

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.

Astronomers use radio emissions from distant galaxy to observe asteroid

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.

Is mercury release cause of New Mexico solar observatory shutdown?

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 resets listening plan for Opportunity

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.

Orion test vehicle completes last parachute test

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.
