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.

September 4, 2018 Zimmerman/Batchelor podcast

9:59 pm

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.

Saturn’s polar hexagonal vortex might tower high above clouds

3:35 pm

The uncertainty of science: A long term analysis of data from the probe Cassini suggests that Saturn’s north polar hexagonal vortex might tower many miles high above the planet’s clouds.

A new long-term study has now spotted the first glimpses of a northern polar vortex forming high in the atmosphere as Saturn’s northern hemisphere approached summertime. This warm vortex sits hundreds of kilometres above the clouds, in a layer of atmosphere known as the stratosphere, and reveals an unexpected surprise. “The edges of this newly-found vortex appear to be hexagonal, precisely matching a famous and bizarre hexagonal cloud pattern we see deeper down in Saturn’s atmosphere,” says Leigh Fletcher of the University of Leicester, UK, lead author of the new study.

“While we did expect to see a vortex of some kind at Saturn’s north pole as it grew warmer, its shape is really surprising. Either a hexagon has spawned spontaneously and identically at two different altitudes, one lower in the clouds and one high in the stratosphere, or the hexagon is in fact a towering structure spanning a vertical range of several hundred kilometres.”

There are many uncertainties here. For one thing, we have not yet even observed Saturn from up close through a complete year. We might be seeing random weather events having nothing to do with the gas giants overall planetary weather patterns.

Roscosmos re-inspecting all Progress/Soyuz capsules

9:48 am

The Russians are going to give all Progress and Soyuz capsules being prepared for launch a new inspection following the discovery that the airleak on the Soyuz docked with ISS had been caused by a technician on the ground prior to launch and covered up.

The consequences to Russia’s space industry because of this incident are going to be difficult to measure. It surely signals that they have still not got a handle on their quality control problems. In fact, it provides further proof that the technical work coming out of Russia is shoddy, sloppy, and filled with many forms of corruption, all circumstances that should give pause to anyone thinking of flying a product or themselves on a Russian-made product.

Worse, the centralized government-run space industry created by Putin is exactly the wrong thing for fixing these problems. Russia does not have a competitive and free aerospace industry. Everything is run by the government and based on the ability to wield political power rather the ability to demonstrate skill and quality in how you do your job.

With only five launches expected in 2019, Russia’s space program is sinking to the level of a third world country. This airleak disaster will only help it sink further.

One last note: I predicted this kind of disaster back in 2013, when the consolidation of Russia’s aerospace industry was announced by the Putin government. My prediction was not very difficult, nor especially brilliant, since disasters like this always occur from government-run top-down socialist/communist systems. One only has to be patient. It is only a matter of time before the system fails, and fails badly.

ISS airleak an accidental drill hole on ground

5:21 pm

The airleak last week on ISS in the orbital module of a Soyuz capsule was not caused by a micrometeorite but by an accidental drill hole made by a technician on the ground who then, rather than reporting it, sealed it and covered it up..

“The hole was made on the ground. The person responsible for the act of negligence has been identified,” the source told the news agency.

Another source said a worker apparently accidentally drilled the hole, but instead of reporting it, simply sealed it. The sealant held for at least the two months the Soyuz spacecraft spent in orbit, before finally drying up and being pushed out of the hole by air pressure.

According to a Moskovsky Komsomolets report, the hole was located near the toilet and covered by decorative fabric. The Russian crew members used an epoxy-based sealant with metallic additives to plug both the hole and a fracture in the outer hull of the Soyuz located behind it, the newspaper said.

Well, if anything is going to put an end to the resistance to using privately built American manned capsule, this should do it. This is also going to do a great deal of harm to the Russian desire to sell tourist seats on their Soyuz.

Sunspot update for August 2018: The slide to minimum

12:28 pm

As it does the first Sunday of each month, yesterday NOAA posted its monthly update of the solar cycle, covering sunspot activity for August 2018. And as I do every month, I am posting it below, annotated to give it some context.

The Sun in August had a slight uptick in sunspot activity, but not a very significant one. As such, the slide to solar minimum continues. Right now the lack of sunspot activity in 2018 is heading to match or even exceed 2007, the year in which the previous solar minimum began.

August 2018 sunspot activity

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

If you look at the original graph at NOAA, you will see that we are getting very close to the right edge of the graph. I expect that sometime in the next few months NOAA will update the graph, a necessary act that will in one sense be a shame, as they have been adding monthly updates to this graph since the beginning of the last solar minimum. This has allowed everyone to see a standard visual, month to month, for comparing solar activity. It has also allowed me to annotate the graph properly to show how the 2007 and 2009 predictions held up against actual activity. Once the graph changes it will be more difficult to do this.

Anyway, it is very clear we are entering solar minimum, and that the solar cycle we are now completing will be both a short and weak cycle. What happens next is really the big question. Will the Sun sunspot activity recover? Or will we enter the first grand minimum since the 1600s? Either way, for solar scientists the coming years are going to be very exciting.

Posted on interstate 10 going from Tucson to Phoenix, on the way to the wooded northern forests of Arizona, where Diane and I will spend a couple of days visiting friends at their upstate cabin/home.

A glider sets new altitude record

9:22 am

The Perlan-2 glider yesterday set a new altitude record, reaching an altitude of more than fourteen miles.

Then on September 2, Perlan pilots Jim Payne and Tim Gardner strapped themselves in and rode the glider to an altitude of 76,000 ft (23,000 m), setting a new flight record. This is higher than Lockheed Martin’s jet-powered U2 spy plane flown by the CIA, which reached 73,700 ft (22,475 m), and places it amongst a handful of manned aircraft to sustain flight at such as altitude.

Implied but unstated in the article at the link is the military value of this technology, once combined with drone technology.

UAE names the two finalists for its first manned flight on Soyuz

9:15 am

The new colonial movement: The leader of Dubai yesterday named the UAE’s the two astronaut finalists, one of which will fly on a Soyuz to ISS sometime next year.

The ruler of Dubai has announced the names of two astronauts from the United Arab Emirates who will be heading to the International Space Station, a first for the Gulf nation. Sheikh Mohammed bin Rashid Al Maktoum, who also serves as the UAE’s vice president and prime minister, made the announcement on Monday on Twitter.

Sheikh Mohammed named the astronauts as Hazza al-Mansouri and Sultan al-Nayadi. Their missions are scheduled for next year.

No biographical information about these two men has yet been released, but I am willing to bet that some UAE politics played a part in their selection. This is not to say that they are unqualified (because both men were cleared to fly by the Russians) but to note the realities that always lurk within any government run space program.

Leftist thugs take over British college

8:10 pm

Evergreen, with a British accent: A leftist cabal of antifa brownshirts has taken over King’s College London, with the administration there bowing to their demands that have shut down any dissent on campus.

The college now faces a scourge unprecedented in the U.K.: rampant violence against visiting speakers on campus. The violence is perpetrated by a small but organized coalition of radical leftist students. Rather than punish those students, the administration has opted to extend free-speech restrictions to the student groups targeted by the unrest. In the aftermath of Antifa’s disruption, the college enacted punitive restrictions on all of the upcoming activities of the Libertarian Society. The college even cancelled a scheduled talk about free speech with Dr. Adam Perkins, one of its own professors.

The administration is being held hostage by intolerant leftist students who dictate which ideas should be restricted through the threat of violence. Speakers associated with the far left are therefore given a free pass when invited onto campus, while conservative, libertarian, and pro-Israel groups are frequently forced to alter their events in order to allay extensive complaints from the agitators. Restrictions forced upon student events by the administration include the imposition of an extra speaker to create debate, a limit on the number of attendees, and, of course, the authoritarian Safe Space policy. The message these restrictions send is that “controversial” ideas, rather than autonomous individuals, drive violence on campus.

Read it all. It will appall you. I hope this college goes bankrupt. I would certainly not send my kids there.

SpaceX’s Big Falcon Rocket and the colonization of Mars

7:49 pm

Link here. Lots of details about what SpaceX wants to do, as well as the company’s request for help in areas it is weak.

Below the fold is the youtube video from the Mars Society conference last week which forms the basis of the article at the link.

I only have one comment at this time: I worry that SpaceX is developing a rocket, the BFR, that has no marketable value, at this time. They succeeded with the Falcon 9 and the Falcon Heavy because they could market them and make money from them. The commercial space industry needed these rockets that could fly at lower cost, and that has paved the way for SpaceX’s success.

There are real questions whether a similar market exists for BFR. To paraphrase a line from the movie Field of Dreams, it is possible that if they build it the customers will come, but few businesses succeed with that market strategy.

Director of Neil Armstrong movie responds to flag critics

9:41 am

The director of the movie about Neil Armstrong, First Man, has issued a statement about criticism the movie is getting for not showing a scene of Armstrong and Aldrin planting the American flag on the Moon.

Below is Damien Chazelle’s statement in its entirety:

In “First Man” I show the American flag standing on the lunar surface, but the flag being physically planted into the surface is one of several moments of the Apollo 11 lunar EVA that I chose not to focus upon. To address the question of whether this was a political statement, the answer is no. My goal with this movie was to share with audiences the unseen, unknown aspects of America’s mission to the moon — particularly Neil Armstrong’s personal saga and what he may have been thinking and feeling during those famous few hours.

I wanted the primary focus in that scene to be on Neil’s solitary moments on the moon — his point of view as he first exited the LEM, his time spent at Little West Crater, the memories that may have crossed his mind during his lunar EVA. This was a feat beyond imagination; it was truly a giant leap for mankind. This film is about one of the most extraordinary accomplishments not only in American history, but in human history. My hope is that by digging under the surface and humanizing the icon, we can better understand just how difficult, audacious and heroic this moment really was. [emphasis mine]

That he did show the American flag on the Moon is encouraging to me, and makes me think that the criticisms about this issue being leveled at the film, including mine, are possibly unfair.

At the same time, I have witnessed too often the desire of Hollywood to denigrate the United States, so I remain suspicious. Getting eyes on the film to get another perspective would I think be very helpful. I might myself have to view it to give my own perspective.

Russian official predicts only 10 launches for 2019-2020

9:24 am

How the mighty have fallen: A Russian official yesterday predicted that they will only do a total of 10 launches for the two year period from 2019 to 2020.

“Five launches are envisaged for 2019. Five launches of manned and resupply ships, and also of a nodal module are planned for 2020,” the vice-premier said at a meeting held at the Energia Rocket and Space Corporation on the problems of piloted cosmonautics in the process of fulfilling long-term space exploration programs. [emphasis mine]

The highlighted words reveal a second tidbit, namely that they apparently will not be launching the Nauka module to ISS in 2019, as previously announced.

In a related story, a Russian space official also confirmed that they will definitely cease flying American astronauts on Soyuz in April 2019, as per the NASA-Russian contract.

The second story does not mention the Soyuz flight seats that Boeing owns, obtained as part of the settlement of the Sea Launch partnership. I wonder about their status. Are the Russians going to block them? I also suspect that this second story might be a negotiating effort by the Russian government to press NASA into buying more flights, something NASA has so far not done.

Either way, the first story essentially places Russian in the bottom echelon of space-launch nations, ranking comparable to what India and Japan have been doing in recent years. Both these countries however expect to up their numbers, which makes Russia’s space future look even more dismal.

For the entire history of space, beginning with Sputnik, the Soviet Union/Russia had consistently dominated the world in annual launches. For them to have fallen so far tells us much about the failed socialist and centralized policies of the Putin government. They do not work. They never work. In fact, they cannot work.

Will someone please tell this fact to both the American Democratic Party, and the many people who continue to vote for its new socialist agenda?

Some debate at NASA over Opportunity

8:58 am

This story yesterday had the following interesting paragraph:

Members of Opportunity’s engineering team recommended a different plan, the person close to the mission says. Their idea was to actively try to communicate with Opportunity until the end of January 2019 — the end of the seasonal cleaning period. After that, they suggested passive listening until the end of 2019. But these recommendations were ignored by management in order to save money, this person says, meaning the agency could be risking abandoning a still-functioning rover. The Opportunity team reportedly didn’t receive formal notice of the plan until “minutes before JPL published its press release,” according to The Atlantic.

It appears that some on the science team do not feel that the present plan to listen closely for only 45 days, through mid-October, is sufficient, as it will likely require a dust devil to clear Opportunity’s solar panels, and dust devil season will not begin until November.

However, it is very likely wrong to blame the resistance by NASA management to this plan solely to a desire to save money. There are other considerations, such as tying up the Deep Space Network for this one rover when, as I noted yesterday, the October to January time period will be a very very very busy time for that network, with many important new planetary probe events. Seven different spacecraft will either be landing or doing fly-bys on four different solar system targets during that time. Tying the network up to listen for Opportunity will likely not work.

It seems to me that Opportunity should be recovered, if possible, but it also must receive a lower priority during this time period. After New Horizons’ January 1st fly-by of Ultima Thule it might be possible to devote more time then to listening, but I can see the logic, at least in this context, for reducing the listening time from October to January.

Hat tip Kirk Hilliard.
