China to attempt to grow potatoes on Moon

9:22 am

China’s Chang’e-4 lunar rover/lander, set to launch in 2018, will include a small experiment that will attempt to grow potatoes from seeds.

Note that I have just realized that I have been confusing Chang’e-5 with Chang’e-4. Chang’e-5 is a sample return mission that they hope to launch this year. It does not include a rover. Chang’e-4 is a lander/rover mission that is planned for 2018.

Boeing cuts management, streamlines its operations

9:14 am

Capitalism in space: In an effort to better compete, Boeing is eliminating a layer of management and cutting 50 jobs in its defense and aerospace division.

The changes split management into smaller units so they can make faster decisions in their specific fields. This includes separating their space and missile division from other activities. This quote however says it all about the accelerating competition in the space business.

The changes are designed to speed decision-making, [defense division head Leanne Caret] said in an interview. “Everything is moving faster,” she said of the competitive environment for defense contractors.

Design questions might delay construction of China’s first big optical telescope

9:03 am

A disagreement over the design of what China hopes would be, for a short while, the world’s largest optical telescope might delay that telescope’s construction.

On one side is an established engineering team, led by a veteran optics expert responsible for the nation’s largest existing telescope, that is eager to push ahead with an ambitious design. On the other are astronomers reveling in a grassroots priority-setting exercise—unprecedented for China—who have doubts about the ambitious design and favor something simpler.

Now, a panel of international experts has reviewed the designs and come out squarely in favor of the simpler proposal, according to a copy of the review obtained by Science. But the conclusion has not ended what one Chinese astronomer calls “an epic battle” between the high-ranking engineers accustomed to top-down control over projects and the nascent grassroots movement.

The telescope would have a mirror diameter of 12-meters, topping the 10.4 meter Gran Telescopio Canarias in the Canary Islands. To get it built in time to be the largest, they need to approve the construction plan by 2018.

The story is interesting in that is highlights the technical problems that exist for these large telescopes, most of which have had serious engineering issues that have limited their scientific output. The disagreement here is caused by an effort by some Chinese scientists to avoid these problems by using a simpler design.

Russians successfully launch Progress to ISS

8:43 am

A Russian Soyuz rocket successfully launched a Progress freighter to ISS early today.

That’s the second Russian launch in less than a week, after a very long pause caused by the discovery of corruption in one of their major engine factories. Though the Russians presently only have two launches scheduled for July, and none scheduled for August, I suspect that this will change in their effort to clear their launch backlog.

KFC pays to put chicken sandwich on four day World View shakedown flight

5:41 pm

Capitalism in space: A publicity stunt by Kentucky Fried Chicken to sell a new chicken sandwich will help pay for the the first long shakedown of World View’s Stratollite balloon.

For World View Enterprises, the flight is expected to serve as a four-day shakedown cruise for its “Stratollite” system, which could eventually send military and commercial imaging payloads to the edge of the atmosphere for months at a time. “When KFC first brought this to us, we had a good chuckle,” World View CEO Jane Poynter told reporters during a teleconference today. But then the Arizona-based company realized there could be a serious point behind the project. “If you can fly a chicken sandwich to the edge of space … you can fly really just about anything,” Poynter said.

Besides, the payment that KFC is providing for the publicity will cover the cost of the test flight, including the expense of beaming down live HD video from a height of 60,000 to 75,000 feet, Poynter said.

Neither she nor KFC brand communications director George Felix would say precisely how much the fast-food chain is paying, but Felix said “we’re fully confident that this is going to be worth every penny.” For reference, NASA has paid World View as much as $440,000 for balloon test flights.

What is interesting to me is how World View appears to have significantly backed off its effort to sell and fly tourists on a balloon.

When World View was founded in 2013, the company’s main objective was to provide hours-long tours to the stratosphere in a pressurized Voyager capsule for $75,000 a ticket. Since then, World View has pivoted to the Stratollite concept, but it still intends to fly people someday. “We’re actually making huge progress,” Poynter said.

Poynter is no longer giving out a timetable for the start of Voyager tours, but she said two more Stratollite missions are scheduled for this summer. MacCallum, who is Poynter’s husband, said a full-scale mass simulator for the Voyager capsule is due to be flown by the end of the year.

All in all, the suborbital space tourism business appears, at least for now, to be fading, overwhelmed by the new and growing orbital launch industry.

Worm grows 2 heads on ISS

5:29 pm

The uncertainty of science: For reasons that are not yet understood, a flatworm fragment flown to ISS in a microgravity experiment regenerated with two heads.

But the most dramatic difference was a type of regeneration observed in one of the 15 worm fragments sent to the ISS. That worm returned to the scientists with two heads (one on each end of its body), a type of regeneration so rare as to be practically unheard of — “normal flatworms in water never do this,” Levin told Live Science. When the researchers snipped both heads off back on Earth, the middle portion regenerated into a two-headed worm again.

“And these differences persist well over a year after return to Earth!” Levin said. “Those could have been caused by loss of the geomagnetic field, loss of gravity, and the stress of takeoff and landing — all components of any space-travel experience for living systems going to space in the future,” he said.

The flatworms that flew in space showed other significant differences from the control group that stayed on Earth, further suggesting that for flatworms at least the environment of weightlessness causes more problems that were expected.

More news from fascist Evergreen State College

10:43 am

The mob riots at Evergreen State College in Washington state have unveiled a number of new facts about that publicly funded leftwing indoctrination mill:

The source of the documents in the first link said this, “I feel compelled to come forward with evidence that the school has allowed student groups (at best) or domestic terrorists (at worse) to indoctrinate freshman into their extremist ideology,” The article also gives a sense about the distribution of these documents and the violent, fascist, leftwing, and anti-American philosophy they promote across many campuses.

From the second article is this tidbit: “Evergreen employees have not given a single dollar to a Republican congressional candidate since 2012.” Since the administration of Evergreen has also been very supportive of the leftist mob that threatened anyone who disagreed with them with violence, the political donations give a nice sense of where the Democratic Party is going.

Finally, one more story today about this fascist university: Evergreen State professor: ‘I have no way of knowing whether it’s safe for me to return’

Durning a recent appearance on Tucker Carlson’s Tonight on Fox News, Professor Bret Weinstien claims that “the college has never acknowledged the danger they put us in,” and that, as a result, “I have no way of knowing whether it’s safe for me to return.”

“Their assurances that it is safe don’t mean anything,” Weinstein said, adding: “Not that they’ve offered them.”

Weinstein noted that he had received “tremendous support” from outside Evergreen State, and “quite a bit of support, privately,” from within the school. Publicly, however, “only one other professor” at Evergreen has come forward to support Weinstein.

But other than that, it’s a great place to send your kids to be educated.

Update: One more story from Evergreen: Students accuse Weinstein of hiding behind Jewishness

What a cesspool of bigotry.

A dust-off broom for Mars

9:22 am

Romanian engineers have developed a small plasma jet capable of blowing Martian dust from solar panels and other equipment that can be used by future missions.

The “plasma broom” solution developed by Ticoş and colleagues uses bursts of plasma jet produced by a simple plasma accelerator. When a large current is passed through two electrode plates separated by a field of rarefied gas, the voltage difference between the two electrodes ionizes the gas, creating the plasma. In the broom, this is done with a coaxial gun – the two metal electrodes are arranged as an inner rod within a hollow cylindrical shell. The discharge current flowing through the central rod electrode produces a magnetic field, which, together with the electric field, exerts a Lorentz force on the ionized gas that expels it. “The trick is that you need a quite high current in order to produce a reasonable magnetic field and this can be achieved more conveniently in a pulsed operation,” Ticoş explains. “For a fraction of a second (100 µs) the current is very high (several kiloamps) and the force pushing the plasma is quite strong.” During a pulse, the plasma is expelled at a very high speed – several kilometres per second – and so can simply blow dust away from an area two to four times bigger than the diameter of the jet.

An advantage of the plasma broom is that it uses low-pressure CO2 as the gas between the electrodes. This is particularly ideal for operation on Mars as the atmospheric pressure there is 150 times lower than on Earth and the atmosphere is 96% CO2. This means the gun will be able to function in “open” Martian atmosphere without the need for a pump or gas bottle. Ticoş and colleagues have also considered the energy required for the cleaner to function on Mars. This depends on the voltage the gun operates at and can vary between a few hundred to a few thousand Joules per pulse. “We did an energy budget estimate taking into account the solar irradiance on Mars,” says Ticoş, “and it appears perfectly feasible to fire a few shots even on a daily basis for cleaning the solar panels, which will boost considerably the energy production rate.”

Essentially, they are using ion engine concepts to create a can of dust-off, using the Martian atmosphere itself as the can.

How NIMH policy effects research

8:24 am

The uncertainty of science: A policy change in how the National Institute of Mental Health (NIMH) awards grants during the Obama administration has had a profound influence on the research of mental-health in the United States.

An analysis by Nature suggests that the number of clinical trials funded by the NIMH dropped by 45% between 2009 and 2015. This coincides with the agency’s launch, in 2011, of the Research Domain Criteria (RDoC) — a framework for research on the mechanisms of mental illness. The NIMH’s roll-out of RDoC included asking researchers to focus more on the biological bases of behaviour — such as brain circuitry and genetics — than on the broader symptoms that clinicians typically use to define and classify mental illness.

The NIMH’s embrace of fundamental research has infuriated many clinical researchers, who see it as an attempt to invalidate their methods — and say that there is scant evidence to support the idea that using RDoC will lead to greater insight or better treatments for mental illness. Many of these researchers also note that NIMH funding for clinical trials has declined steadily over the past decade, adding to the perception that the agency now favours research that uses the RDoC framework.

Read the article. I have no idea if the change in NIMH policy is a good or bad thing. What disturbs me however is the federal government’s overall top-down control over mental-health research. Rather than obtain funding from many different sources — which would allow for the greatest flexibility and the most creativity — this research field appears to depend almost entirely on NIMH grants. Thus, the particular preferences of that agency dictates the nature of the research, whether or not its preferences are right.

House committee passes new commercial space bill

5:09 pm

Last week the House Science committee passed a new commercial space bill designed to streamline the licensing system that presently exists for getting private space missions certified as required under the Outer Space Treaty.

The bill reforms the existing licensing system for commercial remote sensing satellites, streamlining a process that many companies in that sector said results in lengthy delays. It also establishes a “certification” process for commercial spaceflight not otherwise licensed today in order to eliminate any regulatory uncertainty and ensure compliance with the Outer Space Treaty.

“The goal of this bill is not to regulate space broadly,” [Committee chairman Lamar Smith (R-Texas)] said in a statement at the markup. “Instead, the bill takes a commonsense approach by establishing a legal foundation upon which U.S. industry can flourish.”

I am in the process of reviewing the proposed law, and hope to write something detailed about it in the next few days. I should say here that in general this law seems to be trying to address the same issues relating to the Outer Space Treaty that have been discussed during the Senate hearings organized recently by Senator Ted Cruz (R-Texas). And while to me the resulting bill seems generally good, it still leaves hanging the Outer Space Treaty’s fundamental problems relating to property rights.

Sunspot update for May 2017

10:32 am

Last week NOAA posted its monthly update of the solar cycle, covering sunspot activity for May. Unfortunately, there appeared to be a problem with their posting software. Though the date of the image changed, the graph itself was not updated. I contacted NOAA, and Ann Newman, IT Specialist at NOAA’s
Space Weather Prediction Center, took a look and quickly fixed the problem.

The corrected graph is posted below, with annotations, as I have done now every month since 2010.

May 2017 Solar Cycle graph

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.

The decline in sunspot activity resumed in May, putting the trend back below the 2007 low prediction. Overall, the trend continues to suggest that this very weak solar maximum will end much earlier than predicted, and will make it an unprecedented short but weak cycle. As the Sun is at this moment blank, and has been for several days, I expect that June will end up with low numbers as well, continuing this trend.

As I have repeatedly said now monthly for six years, if history is any guide, the Sun’s low activity should correspond with cooler temperatures here on Earth. Why this happens is not yet understood, though there are theories.

What ISRO charges for a launch

12:40 am

Capitalism in space: This article, outlining the overall expenditures and earnings of India’s space agency, ISRO included this tidbit about the price it charges for launches:

Several companies like SpaceX’s Falcon 9, Russia’s Proton ULA, and Arianespace are big names in the space but ISRO’s Antrix provides competitive rates for commercial launches. ISRO, that has now become a specialist in launching satellites, cost a third of SpaceX launches. The low rates are probably because of ISRO’s location while its Indian engineers earn a fraction of the salaries that engineers would command in foreign countries. [emphasis mine]

If India does charge in the range of $20 to $30 million per launch they are in a strong position to compete with SpaceX, even after it reduces its prices because of the use of used first stages.

Luxembourg revises space law to address Outer Space Treaty

8:11 pm

Luxembourg has revised its proposed new space law in order to try to address the property right concerns posed by the Outer Space Treaty.

The legislation is patterned on the U.S. Commercial Space Launch Competitiveness Act of 2015, which includes provisions that grant U.S. companies the rights to resources they extract from asteroids or other celestial bodies. One difference, Schneider said, will be that while the U.S. law requires companies to be based in the country, Luxembourg’s protections would cover companies regardless of their location. “We don’t really care where the money comes from,” he said.

The bill also creates a system for the authorization and continuing supervision of commercial space activities that are regulated by the country. The lack of similar policy in the United States for “non-traditional” commercial space activities like asteroid mining — required, many argue, in order to comply with Article 6 of the Outer Space Treaty — has been an issue debated in the last few years.

…Luxembourg is also in the process of creating a national space agency, Schneider said. The country is a member of the European Space Agency but has not previously had its own national agency. However, he said the agency will be structured differently than those in other countries. “This space agency will not be a copy of NASA or ESA, but it will be a space agency whose only focus on the commercial use of space resources,” he said. It will be set up a public-private partnership between the government and private funds.

I would say that the competition in space is definitely now heating up. These actions by Luxembourg might not solve the legal problems with the Outer Space Treaty, but they will certainly up the pressure on the world’s space-faring nations to face the issue.

At the rim

8:00 pm

at the rim

On a lark, last week I called Xanterra, the vendor that runs the hotels on the south rim of the Grand Canyon, to see if they had any rooms available anytime during the summer. Diane and I wanted to do a day hike down the Hermit Trail, and to do it we needed to stay at a hotel the night before and the night after.

To my surprise, they had a rim view room available in Bright Angel Lodge, for tonight and tomorrow. The picture on the right is taken from our room, right after we arrived earlier today. I am right now sitting at that window, watching the sun set on the canyon buttes even as I type. Yowza!

I will post more tonight, and some tomorrow night as well. I will also do my podcast with John Batchelor tomorrow, live, from this room. Most cool, I must say.

T Rex fossils suggest it was covered with scales, not feathers

9:04 am

The uncertainty of science: The only known fossils of a T Rex’s skin suggest that the dinosaur was covered with scales, not feathers as recent research has theorized.

[I]f these large tyrannosaurs had any feathers at all, says the team, their fluff would have been limited to their backs—the only body part for which they were lacking fossil impressions. Because their earlier cousins did have feathers, it’s likely that the large tyrannosaurs lost them somewhere along the way, the team suggests.

Astronomers confirm that comet caused Wow! signal, not aliens

9:01 am

Astronomers have confirmed that the Wow! signal, thought to be the most promising detection by SETI of alien life, was actually caused by a comet.

Last year, a group of researchers from the Center of Planetary Science proposed a new hypothesis that argued a comet might be the culprit. The frequency could be caused by the hydrogen cloud they carry, and the fact that they move accounts for why it seemingly disappeared. Two comets, named 266/P Christensen and P/2008 Y2 (Gibbs), happened to be transiting through that region of space when the Wow! signal was detected, but they weren’t discovered until after 2006.

To test the hypothesis, the team made 200 radio spectrum observations between November 2016 and February 2017. Sure enough, 266/P Christensen was found to emit radio waves at a frequency of 1,420 MHz, and to double check, the researchers moved their radio telescope by one degree. As expected, the signal vanished, and only returned when the telescope was trained back on the comet.

This story demonstrates once again why, in science, it is very dangerous to jump to any conclusions. The data we receive is a mystery. We must keep an open mind to solve that mystery.

China reveals landing site for Chang’e-5 lander/rover

8:56 am

China has chosen the landing site for its Chang’e-5 lander/rover and sample return mission, planned to launch later this year.

Liu Jizhong, director of China Lunar Exploration and Space Engineering Center of China National Space Administration (CNSA), for the first time disclosed the probe landing site, an isolated volcanic formation located in the northwest part of the Moon’s near side.

They also said their focus will be the Moon’s south pole, where there is evidence of the possible presence of water ice.

Russia lowers its Proton launch plans for 2017

8:52 am

Though they are about to resume Proton launches, Russia today revealed that they only intend to launch the rocket five times in 2017, not seven as announced earlier.

Russia plans five Proton-M carrier rocket launches this year, including three commercial launches, Khrunichev Space Center CEO Andrei Kalinovsky told TASS on Wednesday. “Our plans for this year also additionally include four Proton-M carrier rocket launches. These are two commercial launches with Amazonas 5 and AsiaSat 9 satellites, and also two federal launches,” the chief executive said.

Even more interesting, the article notes that Russia only has contracts to launch 15 commercial satellites through 2023. That’s a launch rate of only about 2.5 to 3 commercial Proton launches per year, a rate that seems much less than in the past. Moreover, while they say they haven’t lost any customers in the past year, it also appears they haven’t gotten any either.

Climate scientists increasingly show no warming in peer review papers

10:19 pm

The uncertainty of science: Climate scientists are increasingly publishing papers that show no clear temperature global trend.

Last year there were at least 60 peer-reviewed papers published in scientific journals demonstrating that Today’s Warming Isn’t Global, Unprecedented, Or Remarkable.

.
Just within the last 5 months, 58 more papers and 80 new graphs have been published that continue to undermine the popularized conception of a slowly cooling Earth temperature history followed by a dramatic hockey-stick-shaped uptick, or an especially unusual global-scale warming during modern times.
.
Yes, some regions of the Earth have been warming in recent decades or at some point in the last 100 years. Some regions have been cooling for decades at a time. And many regions have shown no significant net changes or trends in either direction relative to the last few hundred to thousands of years.
.
Succinctly, then, scientists publishing in peer-reviewed journals have increasingly affirmed that there is nothing historically unprecedented or remarkable about today’s climate when viewed in the context of long-term natural variability. [emphasis in original]

At the link are 80 graphs from the most recent papers. Take a look. If you are convinced that the climate is warming than you must come up with an explanation for this data. Or you can put your fingers in your ears, cover your eyes, and chant “La-la-la-la-la-la-la-la-la-la-la-la-la-la-la-la!” as loud as you can so that you don’t have to deal with it.

China to ramp up manned missions to build space station

5:10 pm

In order to build its space station, beginning in 2019, China will increase its manned mission rate, completing four missions in five years.

This is still a somewhat glacial pace, compared to other nations. It will seem even slower based on what I expect will start happening once a number of competitive private American rockets begin hauling tourists into space.

The article notes one additional tidbit about China’s station. They plan to run 3 to 6 month long missions there.

Jupiter gets two more moons

4:51 pm

Astronomers using ground-based telescopes have identified two more moon circling Jupiter, bringing its total now to 69.

Both of these discoveries, as with the vast majority of Jupiter’s moons, occupy retrograde orbits, with inclinations greater than 90°, meaning that they move in directions opposite that of the planet’s spin. These distant, irregular orbits imply that these bodies formed elsewhere in the outer solar system and were captured while passing by early in the planet’s history.

A number of the moons recently discovered have since been lost because their orbits were too poorly constrained. However, some of these lost moons have also be recovered.

Air Force awards SpaceX contract to launch next X-37B mission

4:47 pm

Capitalism in space: The Air Force has awarded SpaceX the contract to launch the next X-37B mission, presently scheduled to launch in August.

The contract amount was not announced, but it certainly is going to be less than ULA charged for its own launches of the X-37B. Also, this launch is scheduled only two months hence, which means SpaceX has to somehow wedge it into its already crowded schedule.

Imans in UK refuse to say prayers for terrorists

4:24 pm

It is about time: More than 130 Muslim religious leaders in the United Kingdom are refusing to perform funeral rites for the terrorists who attacked people this past Saturday on London Bridge.

The decision by the Muslim leaders was seen as an “unprecedented” move because the funeral ritual is typically performed on a deceased Muslim no matter the person’s past actions. The group of religious leaders have urged others to join them in declining to pray for the dead killers.

“We, as Muslim imams and religious leaders, condemn the recent terror attacks in Manchester and London in the strongest terms possible,” the Muslim leaders said in a statement. “Coming from a range of backgrounds, and from across the U.K.; feeling the pain the rest of the nation feels, we have come together to express our shock and utter disgust at these cold-blooded murders. We are deeply hurt that a spate of terror attacks have been committed in our country once more by murderers who seek to gain religious legitimacy for their actions. We seek to clarify that their reprehensible actions have neither legitimacy nor our sympathy.”

So, does this mean they had no problems with performing rites for the terrorists of earlier attacks, such as at Westminster earlier this year and the July 7 attacks several years ago? Meh.

I must say that though this is the right response on their part, I am not very impressed. For more that two decades the Islamic community in the west has sat on its hands, making believe they have nothing to do with Islamic terrorism, or quietly supporting it by non-action. They are suddenly realizing now that people are losing patience with them, and that their safe havens in the west are now increasingly threatened. Most politicians might still be mouthing platitudes of “We have to all get along,” but the public is increasingly angry and demanding action, even if it means kicking every Islamic practitioner back to the Middle East.

Thus, though I do not like attacking people with such broad strokes, I can understand why it is happening. And the Muslim community has no one to blame but themselves.

The atomic rocket that never was

11:19 am

Link here. The article is filled with overstatements and even a few outright errors, such as in the second paragraph when it makes the false assertion that SLS will be “the largest booster ever built.” (The Saturn 5 was more powerful. So was the Soviet Union’s Energia.)

Furthermore, the key to understanding how minor and inconsequencial Project Orion was is to note the total amount of money spent: only $10.5 million. This was merely a design study, something that NASA did (and still does) routinely, most of which never get beyond power-point presentations. Project Orion was similar, never reaching project stage. If it had been done today it would have also been nothing more than a power point presentation.

I also remember when this whole concept got cancelled and was revealed. No one took it seriously, since everyone understood that the technology available in the 1960s was simply not ready for such a project.

Nonetheless, it is interesting reading, especially since the technology today is significantly advanced. We might actually be approaching a time where this concept can finally move to design and construction.

Fascism at Emerson College

9:22 am

Link here. This includes threats of violence, blacklisting, and bad grades for conservative students. One student has left the school after one year because of the harassment.

The worse aspect of this however is that most of the ill-treatment is coming from students. While the administration simply looks the other way, these future leaders of our society harass, oppress, and attack a dissenting minority, merely because of their opinions.

Even so, the very fact that the administration seems to care so little about reigning in this fascist behavior should be a reason for parents and college-bound students to consider attending a different college. As the student who is fleeing the school noted in the second link above:

She’s said she feels disappointed with [Emerson President Lee] Pelton’s response to her situation and a lack of serious consequences for the students involved. “When it comes to the bigger picture, is the school responding well? No. Not really. They don’t feel the need to stand up for us, because they aren’t too many of us,” she said.
