Baby volcanoes on Mars

Pitted cones on Mars

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.

Overview map

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.

New enrollment at Evergreen drops 50%

8:56 am

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.

Ariane 6 gets first commercial contract

8:38 am

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.

Faulty concrete at Vostochny launchpad caused by contractor

8:30 am

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.

India unveils spacesuit for Gaganyaam manned mission

8:24 am

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.

Solar observatory closed for unstated security reasons

10:38 am

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.

Science paper slams IAU planet definition

10:26 am

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.

Trump administration to shutter PLO office in DC

10:13 am

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.

More aerospace problems in Russia

9:31 am

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.

SpaceX successfully launches communications satellite

9:12 am

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.

Second Chinese company completes suborbital rocket test

5:48 pm

For the second time this week, a Chinese “private” company successfully completed a suborbital rocket test.

This time the launch was by OneSpace, which should not be confused with the other company, iSpace. As with iSpace, the rocket used was a solid rocket, which once again makes me think it is doing work for the Chinese military, and is therefore not as independent or as private as Americans normally consider private companies.

Moreover, the launch was filmed by one of China’s spy satellites, also suggesting the military’s interest in this rocket company’s development. You can see both a ground-based and that satellite’s view of the launch at the link.

Japan to launch space elevator experiment to ISS

5:40 pm

When Japan launches its unmanned freighter to ISS on September 10, it will carry a two-cubesat engineering test of some of the concepts required to build a space elevator.

In the experiment, which will be the first of its kind in space, two ultrasmall cubic satellites, or “cubesats,” will be released into space from the station. They will be connected by a steel cable, where a small container — acting like an elevator car — will move along the cable using its own motor. A camera attached to the satellites will record the movements of the container in space, according to the Japanese newspaper The Mainichi.

Each cubesat measures just under 4 inches (10 centimeters) on each side. The cubesats will be connected by a 33-foot-long (10 meters) steel cable for the “elevator car” to move along, according to the report.

I wonder if this experiment will also test some of the technology needed for generating electricity using a tether. Over the decades there have been a number of experimental attempts in space of this concept, all of which have failed for a variety of reasons, all unrelated to the concept itself.

Jupiter’s weird magnetic field

11:34 am

New data from Juno has revealed that Jupiter’s magnetic field acts like it has three poles, one at each pole and another near the equator.

If Earth’s magnetic field resembles that of a bar magnet, Jupiter’s field looks like someone took a bar magnet, bent it in half and splayed it at both ends. The field emerges in a broad swath across Jupiter’s northern hemisphere and re-enters the planet both around the south pole and in a concentrated spot just south of the equator, researchers report in the Sept. 6 Nature.

“We were baffled” at the finding, says study coauthor Kimberly Moore, a graduate student at Harvard University.

They think the multiple poles are a result of the complexity of Jupiter’s inner core, which likely does not have the same kind of organization as a rocky terrestrial planet.

India teams up with France to prep for its first manned mission

10:25 am

The new colonial movement: India has signed a cooperative deal with France to provide them help in preparing for its first manned mission in 2022, now dubbed Gaganyaan by India’s press.

Following the signing of agreements between the two parties on Thursday, the agencies “will be combining their expertise in the fields of space medicine, astronaut health monitoring, life support, radiation protection, space debris protection and personal hygiene systems.”

The announcement was made by CNES [France’s space agency] president Jean-Yves Le Gall during the inaugural of Bengaluru Space Expo-2018 where he was the chief guest. It is being organised by the Confederation of Indian Industry along with ISRO and Antrix, the agency’s commercial arm, from September 6 to 8.

The two countries will also work together on other space research.

Hayabusa-2 scientists release updated landing schedule

10:20 am

The science team for Hayabusa-2 has released an updated landing schedule.

Two of the landers developed by the Japanese space agency will be deployed together by Hayabusa 2 on Sept. 21, and another landing probe provided by German and French scientists is set for its descent to Ryugu on Oct. 3.

Those landing attempts will be preceded by a landing rehearsal using the Hayabusa 2 spacecraft to approach within 100 feet (30 meters) of Ryugu next week. The spacecraft is scheduled to reach its closest point to the asteroid Sept. 12, low enough to fire and test its laser range finder, a navigation sensor to be used on future touch-and-go maneuvers to snag a sample of Ryugu for return to Earth.

Below is the very busy planetary probe schedule through January:

  • Week of September 12: Hayabusa-2 will do dress rehearsal of its Ryugu landing
  • September 21: Two of Hayabusa-2’s three Minerva-II mini-landers will land on Ryugu
  • October 3: Another Hayabusa-2 mini-lander, MASCOT, will land on Ryugu
  • October 3: The Parker Solar Probe makes first fly-by of Venus
  • Late October: Hayabusa-2 itself will land and grab a sample of Ryugu
  • November 26: The U.S. lander InSight will land on Mars.
  • December 3: OSIRIS-REx will arrive at the asteroid Bennu.
  • December: Chang’e-4 will land on the Moon’s far side.
  • January 1: New Horizons will fly past the Kuiper Belt object Ultima Thule.

During this time period Curiosity will also make two more drill attempts, and then resume its climb up Mount Sharp.

TESS releases its first batch of exoplanet candidates

9:59 am

The science team for the U.S.’s exoplanet space telescope TESS this week released its first batch of exoplanet candidates.

TESS scientists released the list so that other astronomers could make an initial determination as to whether these candidates are planets. There are 73 objects in this first batch, including some planets previously known from ground-based searches, says George Ricker, the mission’s principal investigator at the Massachusetts Institute of Technology in Cambridge. Perhaps 5 to 20% of the objects on the list will turn out to be false alarms, he says. Others, if confirmed, will join the ranks of newly discovered exoplanets.

Researchers expect TESS to find as many as 10,000 large planets. But its main goal is to discover and measure the masses of at least 50 small worlds no more than four times the size of Earth.

Meanwhile, Kepler has resumed operations despite being almost out of fuel. The science team there is attempting to squeeze every last ounce of data it can before the spacecraft’s fuel runs out.

Russia begins construction of Angara launchpad at Vostochny

9:52 am

Russia has begun the construction of the first Angara launchpad at their new Vostochny spaceport.

According to earlier reports, the Angara launch pad is to be completed by December 31, 2022. Construction costs are estimated at nearly 39 billion rubles ($565 million).

Somehow it seems to me that this construction is too expensive and is taking too long. A launchpad is essentially a specialized building on the surface. I don’t see why it should be so difficult or expensive to do.

China launches ocean survey satellite

9:42 am

Locations of two of China's launchsites

China today launched the third satellite in a constellation of ocean-observing satellites, using its Long March 2C rocket.

Though this is the same rocket that dropped its upper stage near a Chinese town in June, the launch came from the Taiyuan launch site, not the Xichang launchsite used in June, so it is unclear if the upper stages fell near populated areas. I would expect so, however, since Taiyuan is located in the middle of China even closer to populated areas than Xichang, as shown on the map to the right.

If the launch went north from Taiyuan, then those upper stages probably landed in Mongolia. I wonder if China has worked out an agreement with that country about dropping toxic first stages onto its territory.

Regardless, in the 2018 launch standings, China now leads the U.S. 24-22. The leaders in the race, with the leading U.S. companies broken out, are as follows:

24 China
15 SpaceX
8 Russia
6 ULA
5 Europe

As mentioned previously, with every launch for the rest of the year China will set a new annual record for itself.

Update on the Parker Solar Probe

8:49 am

Link here. The press release notes that the spacecraft’s instruments are one by one being made operational without problem and that it has also successfully completed a second course adjustment.

The release also provided a link to a page which will shows the probe’s present location. This is useful, as it also shows the probe’s position in relation to the Sun, Venus, and the Earth.

Curiosity to drill twice more on Vera Rubin Ridge

3:45 pm

Before they will resume the journey up Mount Sharp the Curiosity science team now plans two more drilling attempts on Vera Rubin Ridge.

The rover has never encountered a place with so much variation in color and texture, according to Ashwin Vasavada, Curiosity’s project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California. JPL leads the Mars Science Laboratory mission that Curiosity is a part of.

“The ridge isn’t this monolithic thing — it has two distinct sections, each of which has a variety of colors,” Vasavada said. “Some are visible to the eye and even more show up when we look in near-infrared, just beyond what our eyes can see. Some seem related to how hard the rocks are.”

Part of this drilling campaign will also include gaining a better understanding better their improvised drilling technique.

More details about Chinese suborbital launch earlier this week

9:56 am

Link here. The article really only provides one new detail about the flight itself, that the rocket used solid rocket motors. This fact, plus the overall secrecy, suggest to me that the company, iSpace, is doing its work for the Chinese military.

The article at the link also provides a good overview of the entire Chinese “private” smallsat rocket industry.

China is still run from the top, so any “private” rocket company must have the approval and support of the government. What makes China different from Russia, also ruled from the top, is the Chinese government’s willingness to encourage competitive independent operations, something the Russians has not done. The result is that China’s rocket industry is not stagnating, but growing.

“Unsteady hand” drilled hole in Soyuz

9:34 am

According to reports in Russia today, Roscosmos head Dmitri Rogozin suggested earlier this week that an “unsteady hand” had made several attempts to drill a hole in the Soyuz capsule.

“There is another version that we are not ruling out; that this was done deliberately in space,” Russian news agency RIA Novosti quoted Rogozin saying.

He indicated there were “several attempts to use a drill” by an “unsteady hand,” scraping the metal areas surrounding the hole, according to RIA Novosti. “We can cut short the idea that this was a technological mistake made by some specialist or other,” he added.

The vision that immediately came to my mind was that of a drunk technician, unhappy about pay, bad living conditions, and corruption, stumbling into the capsule, drilling the hole. Later, after he sobered up he realized the disaster he had created for himself and tried to fix it secretly.

Then again, it is dangerous to take seriously anything Dmitri Rogozin says. He could be trying to spin the situation to his advantage.

Embedded below the fold, in two parts. The first segment covers two subjects in depth: First, the airleak on the Soyuz capsule on ISS and the consequences for Russia, and second, the controversy over the decision by the filmmakers of the movie First Man to leave out the scene where the astronauts planted the American flag on the Moon. With the second topic I outline my present thoughts about this in detail, something I think my readers might find edifying.

University censors student handing out “Jesus loves you” valentines

9:29 pm

Fascist academia: Northeast Wisconsin Technical College has blocked a student from handing out “Jesus loves you” valentines, calling her actions “disruptive.”

A Wisconsin student sued her school on Tuesday after the administration labeled her a “disruptive student” for handing out Valentine’s Day cards reading “Jesus loves you.” Northeast Wisconsin Technical College (NWTC) student Polly Olsen sued her school for what she termed an “unconstitutional” Public Assembly Policy, according to a lawsuit obtained by Campus Reform. “Ms. Olsen was not selling the Valentines, soliciting donations, or asking the recipients for anything. Everyone was free to decline them.”

NWTC restricts what it deems as “disruptive” free expression and free speech, as protected by the First Amendment, to a tiny box on campus that makes up less than one percent of the campus. Olsen described the school’s “free speech zone” as “about the size of two buses next to each other,” highlighting the fact that no one “congregates there, they just walk through,” something she suggested prohibited her from having meaningful conversations with others.

The school’s restrictive speech policy appears blatantly unconstitutional. At the minimum it is oppressive and unreasonable, preventing individuals from exercising their first amendment rights. I hope she wins, costing the school both money and reputation. It is not a place I’d send my kids.

New study: Forest cover has blossomed since 1980s

4:43 pm

The uncertainty of science: According to new research the world’s tree canopy has grown by almost a million square miles since 1982.

While the area of bare ground and short vegetation is diminishing, forest area is growing. As Ronald Bailey notes in Reason, “Forests in montane regions are expanding as climate warming enables trees to grow higher up on mountains.”

The greatest increase in tree canopy occurred in Europe, including European Russia, where it exploded by 35%. A close second was found in China, where tree canopy gained 34%. In the U.S., tree canopy increased by 15%.

This study confirms numerous other forest and agricultural research that has shown that increased carbon dioxide in the atmosphere encourages plant growth. Numerous other studies have also found that the Earth has been greening in the past century.

My review of the scientific literature on this subject also matches this finding, having found that if global warming is happening, research looking at what has actually happened generally show that increased CO2 and warming have tended to have beneficial effects, despite the endless doomsday predictions by global warming scientists of what might happen.

How I spent the past two days

4:01 pm

Black Canyon

I must apologize for the lack of posting the past two days. Diane and I have been up in northern Arizona staying at a friend’s cabin, hiking each day. The picture on the right shows Diane (right) and Jan Jantzer, whose house we have been staying, on today’s hike in Black Canyon, a canyon near Heber that is known by locals but is off the radar for most everyone else. Quite beautiful, especially because the recent rain has brought out the wildflowers. In addition, a forest fire about a dozen years ago cleared everything out, leaving behind a scattering of blackened tree trunks, many fallen logs, and open ground on which new growth has blossomed.

The canyon is also different in that it is wide and open, with sloping grassy walls interspersed with rocky cliffs. Most canyon hikes aim for high vertical walls and sculptured rock. Black Canyon instead was focused on the vegetation. As I said, very beautiful, and another example of why I left the crowded eastern United States for lovely Arizona.

I must add that the general news this week is so insane and filled with hatred that I needed a break.

Normal posting shall resume momentarily.
