Hayabusa-2 takes first photos of target asteroid Ryugu

8:34 am

On June 10 Hayabusa-2 took its first photos of Ryugu, the asteroid it will reach later this month.

The Sunday photos were taken when Hayabusa2 was about 930 miles (1,500 kilometers) from Ryugu. Last week, JAXA released a few ONC-T images taken on June 6, when the probe was 1,615 miles (2,600 km) from the space rock.

Hayabusa2, which launched in December 2014, is scheduled to arrive at Ryugu on or around June 27. At that time, the probe will begin orbiting the asteroid at an altitude of about 12 miles (20 km), JAXA officials have said.

Hayabusa2 will then start prepping for a series of complex, up-close studies of the space rock. If all goes according to plan, over the ensuing 12 months, the spacecraft will deploy three rovers and a lander on Ryugu’s surface, gouge out a small crater using an explosives-bearing impactor, and collect samples from the newly created crater.

The spacecraft will depart Ryugu in November or December 2019, and its collected samples will come back to Earth in a special return capsule in late 2020.

The image suggests that the asteroid is “not significantly elongated.”

June 8, 2018 Zimmerman/Pratt podcast

12:28 pm

The podcast for my June 8th appearance on Robert Pratt’s Pratt on Texas radio show is now available here.

The discussion was focused on statements by Senator Ted Cruz (R-Texas) in support of continued funding for ISS. For a guy who ran for President under the banner of destroying what he called the “Washington cartel,” his present position lobbying hard for big space projects seems quite hypocritical, and requires some analysis.

The mysterious dust surrounding Tabby’s Star

8:44 am

New studies of Tabby’s Star suggest that the dust clouds that cause it to fluctuate in brightness in apparently random ways are unusual and baffling in their own right.

[I]t appears that the dimming of Tabby’s star comes not from large objects such as swarms of asteroids, comets, or alien solar collectors, but from drifting bands of dust particles. But like any good mystery, it’s not quite that simple.

Each of the four dimming events observed in 2017 affected red and blue light differently, suggesting that they involved dust particles of different sizes. And the long-term brightness changes appear to be associated with much larger grains. “So the dust cloud is extremely complex,” Bodman says. “Each dip is a different kind of dust … What we’re seeing is different parts of the [dust] cloud as they pass in front of the star.”

A first guess, probably wrong, is that the four dimming events were caused by dust streams orbiting the star at different distances, each a different patchy ring around the star made up of slightly different materials.

And if you accept my guess as right, I also have bridge in Brooklyn I want to sell you. Real cheap too!

China cracks down on corrupt science

8:38 am

The Chinese government has instituted new policies aimed at shutting down corrupt practices in journal peer review and funding that have previously encouraged scientific misconduct.

The country’s most powerful bodies, the Chinese Communist Party and the State Council, introduced a raft of reforms on 30 May aimed at improving integrity across the research spectrum, from funding and job applications to peer-review and publications.

Under the new policy, the Ministry of Science and Technology (MOST) will be responsible for managing investigations and ruling on cases of scientific misconduct, a role previously performed by individual institutions. And for the first time, misconduct cases will be logged in a national database that is currently being designed by MOST.

Inclusion in the list could disqualify researchers from future funding or research positions, and might also affect their ability to get jobs outside academia. The Chinese Academy of Social Sciences will oversee the same process for social scientists. The policy also states that MOST will establish a blacklist of ‘poor quality’ scientific journals, including domestic and international titles. Scientists who publish in these journals will receive a warning, and those papers will not be considered in assessments for promotions, jobs and grants. A couple of such blacklists already exist, but rarely are they run formally by a government agency.

In recent years China has been the source of many examples of blatant scientific misconduct, from faking data in papers to getting them peer reviewed by non-existent reviewers. This policy change is aimed at stopping this misconduct, and is likely happening because much of China’s leadership comes from its space industry, which requires honesty in its work or the rockets will crash.

At the same time, the policy gives the government great power over all scientific work, and we all know what happens eventually when you give the government great power. While the goals here are laudable, and will likely in the near future produce positive results, the long term consequences will likely end up stifling independent research.

The history of the second amendment

10:31 pm

Link here. Anyone who wishes to avoid being willfully ignorant about the reasons and background to the second amendment and presently feels lacking in knowledge will find this essay immensely clarifying. Bottom line:

Again, both sides [in the debate over the ratification of the Constitution] not only agreed that the people had a right to be armed, both sides assumed the existence of an armed population as an essential element to preserving liberty. The framers quite clearly had adopted James Harrington’s political theory that the measure of liberty attained and retained was a direct function of an armed citizenry’s ability to claim and hold those rights from domestic and foreign enemies.

And from the conclusion:

English history made two things clear to the American revolutionaries: force of arms was the only effective check on government, and standing armies threatened liberty. Recognition of these premises meant that the force of arms necessary to check government had to be placed in the hands of citizens. The English theorists Blackstone and Harrington advocated these tenants. Because the public purpose of the right to keep arms was to check government, the right necessarily belonged to the individual and, as a matter of theory, was thought to be absolute in that it could not be abrogated by the prevailing rulers.

These views were adopted by the framers, both Federalists and Antifederalists. Neither group trusted government. Both believed the greatest danger to the new republic was tyrannical government and that the ultimate check on tyranny was an armed population. It is beyond dispute that the second amendment right was to serve the same public purpose as advocated by the English theorists. The check on all government, not simply the federal government, was the armed population, the militia. Government would not be accorded the power to create a select militia since such a body would become the government’s instrument. The whole of the population would comprise the militia. As the constitutional debates prove, the framers recognized that the common public purpose of preserving freedom would be served by protecting each individual’s right to arms, thus empowering the people to resist tyranny and preserve the republic. The intent was not to create a right for other governments, the individual states; it was to preserve the people’s right to a free state, just as it says. [emphasis in original]

Read it all. It puts this issue of gun rights into historical and accurate context. That there are Americans today that do not know these facts, and refuse to learn them, speaks very poorly of them. It also suggests their goal is not the prevention of violence but the oppression of others. Such a goal is directly threatened by these historical facts — describing the British and American search for liberty and freedom — which is why they do not wish them known, and often do whatever they can to suppress them.

Growing Martian dust storm forces Opportunity to suspend operations

4:37 pm

A growing Martian dust storm has forced the Opportunity science team to suspend science operations and to reconfigure the rover’s operations to increase its chances of surviving the storm.

In a matter of days, the storm had ballooned. It now spans more than 7 million square miles (18 million square kilometers) — an area greater than North America — and includes Opportunity’s current location at Perseverance Valley. More importantly, the swirling dust has raised the atmospheric opacity, or “tau,” in the valley in the past few days. This is comparable to an extremely smoggy day that blots out sunlight. The rover uses solar panels to provide power and to recharge its batteries.

Opportunity’s power levels had dropped significantly by Wednesday, June 6, requiring the rover to shift to minimal operations.

This isn’t Opportunity’s first time hunkering down in bad weather: in 2007, a much larger storm covered the planet. That led to two weeks of minimal operations, including several days with no contact from the rover to save power. The project’s management prepared for the possibility that Opportunity couldn’t balance low levels of power with its energy-intensive survival heaters, which protect its batteries from Mars’ extreme cold. It’s not unlike running a car in the winter so that the cold doesn’t sap its battery charge.There is a risk to the rover if the storm persists for too long and Opportunity gets too cold while waiting for the skies to clear.

In other words, there is a possibility that the rover might not make it through this period of low sunlight. Nonetheless, the rover did send four images down yesterday, though the four images are essentially dust filled, and are likely aimed at the far distance to help gauge the extent of the storm.

Woman sues NASA to keep possession of moon dust

4:24 pm

A Tennessee woman is proactively suing NASA in order to guarantee the agency will not try to steal a vial of moon dust that Neil Armstrong gave to her in the early 1970s.

Murray Cicco received the small glass vial full of gray moon dust in the early 1970s. The vial came with a note: “To Laura Ann Murray — Best of luck — Neil Armstron Apollo 11.” …Armstrong’s note and signature have been verified and testing has confirmed the contents in the vial he gifted her do include dust from the moon.

Decades after receiving the glass vial of moon dust, Murray Cicco is moving forward with her federal court case in Wichita, even though she lives in Tennessee. The reason for filing the case in Kansas goes back to a previous case in 2016 where a U.S. District Court judge in Wichita ruled in favor of a collector who bought a bag containing moon dust that was mistakenly placed in an online government auction. In that case, the bag was then sold at auction last year for $1.8 million.

While NASA hasn’t demanded Murray Cicco give up the vial of moon dust, Murray Cicco’s attorney has requested a jury trial in Wichita to stay ahead. “There is no law against private persons owning lunar material. Lunar material is not contraband. It is not illegal to own or possess,” the court document detailing the case says. “Therefore, she requests judgment declaring her the rightful and legal owner of the vial and its contents, and vesting title in her name.”

This is a very wise move on her part. NASA has for years made it clear that it thinks it owns all moon material brought back by the Apollo missions, and has had the arrogant policy of demanding the return of any moon dust or rocks that it discovered was in the possession of any private citizen, no matter how small, or how well documented the ownership. This court case acts to block such actions, before NASA can even think of them.

SpaceX outlines plans for major expansion at Kennedy

4:15 pm

Capitalism in space: According to plans outlined in a draft environmental statement, SpaceX is planning a major mission control and new rocket processing facility at the Kennedy Space Center.

It will be an operational monument to Elon Musk’s vision: a towering SpaceX launch control center, a 133,000-square-foot hangar and a rocket garden rising in the heart of Kennedy Space Center.

According to plans detailed in a draft environmental review published recently by KSC, SpaceX will undertake a major expansion of its facilities at the space center sometime in the not-too-distant future. The review says SpaceX is seeking more room and a bigger presence “in its pursuit of a complete local, efficient, and reusable launch vehicle program.” The expansion would enable SpaceX to store and refurbish large numbers of Falcon rocket boosters and nose cones at the operations center down the road from NASA’s Vehicle Assembly Building.

The most eye-opening detail in this environmental draft is a statement that this SpaceX facility will be designed to support an expectation of up to 63 launches per year. In the first decade of this century that’s about how many launches the entire world accomplished per year. SpaceX’s ambitions here however are not absurd. They instead hearken to the expected upcoming boom in the entire aerospace, mostly fueled by the lower launch costs that SpaceX forced on the launch industry. SpaceX might manage that many launches, but it will be only a part of the entire booming launch market.

Northrop Grumman’s first Pegasus launch delayed indefinitely

10:47 pm

The first launch of a Pegasus rocket following the completion of the sale of Orbital ATK to Northrop Grumman has been delayed indefinitely because of “off-nominal data” detected in the rocket.

The payload is a NASA climate research satellite dubbed ICON. The rocket and launch crew were on board the L1011 carrier plane on they way to the Pacific launch area for next week’s launch when they detected the issue and decided to return to California.

This is not the first problem with this particular Pegasus launch.

ICON’s launch has been delayed a year by a pair of concerns with its Pegasus launcher. Engineers wanted more time to inspect the Pegasus rocket motors after they were mishandled during shipment to Vandenberg, officials said. That pushed the launch back from June to December 2017, the next availability in the military-run range at Kwajalein.

Then managers decided to ground the mission to assess the reliability of bolt-cutters used to jettison the Pegasus rocket’s payload fairing and separate the satellite in orbit. Workers installed smaller bolts in the fairing and satellite separation mechanisms, a measure officials said will ensure the cutters do their jobs.

For Northrop Grumman this isn’t the best way to start its new rocket business, but better a delay than a failed launch.

More Earthlike exoplanets!

9:13 am

Astronomers using data from Kepler have discovered two stars, both with multiple orbiting Earth-sized planets. One has three planets all almost exactly the mass of Earth.

The first exoplanetary system is located in the star K2-239, characterized by these researchers as a red dwarf type M3V from observations made with the Gran Telescopio Canarias (GTC), at the Roque de los Muchachos Observatory (Garafía, La Palma). It is located in the constellation of the Sextant at 50 parsecs from the Sun (at about 160 light years). It has a compact system of at least three rocky planets of similar size to the Earth (1.1, 1.0 and 1.1 Earth radii) that orbit the star every 5.2, 7.8 and 10.1 days, respectively.

The other red dwarf star called K2-240 has two super-Earth-like planets about twice the size of our planet. Although the atmospheric temperature of red dwarf stars, around which these planets revolve, is 3,450 and 3,800 K respectively, almost half the temperature of our Sun, these researchers estimate that all planets discovered will have temperatures superficial tens of degrees higher than those of the planet Earth due to the strong radiation they receive in these close orbits to their stars.

Knowing more about the surface environments of these very Earthlike exoplanets, as hostile as they might be to life, would teach us a great deal about our own planet and its birth and evolution.

Curiosity finds methane fluctuates seasonally in Gale Crater

9:05 am

Seasonal methane on Mars

In its second significant science release yesterday (the first relating to the discovery of organics), the Curiosity science team revealed that they have found over almost three Martian years the amount of methane in the atmosphere appears to fluctuate seasonally. The graph on the right illustrates this change.

[The data] show methane rises from just above 0.2ppb in the northern hemisphere winter to a fraction over 0.6ppb in the summer. The team’s best explanation is that methane is seeping up from underground, perhaps from stored ices, and is then being released when surface soils are warmed.

The team cannot positively identify the origin of the methane, but the researchers think they can close down one particular mechanism for its production. This involves sunlight breaking up carbon-rich (organic) molecules that have fallen to the planet’s surface in meteorites.

The variation in ultraviolet light over the course of the seasons is not big enough to drive the scale of the change seen in the methane concentration, says Dr Webster. “We know the intensity of the Sun and this mechanism should produce only a 20% increase in methane during the summer, but we’re seeing it increase by a factor of three,” he explained.

The change could be caused by either a chemical or a biological process. At this time there is no way to determine which.

Germany to do partial gravity experiments using Zero-G airplane

8:53 am

In what might be the first human experiments in partial gravity, Germany has hired the Zero-G airplane for a series of flights testing how humans react in such conditions.

In the Partial G Campaign, the pilots fly three special parabolic shapes. So instead of zero-g or microgravity, one quarter, half and three quarters of Earth’s gravity will still be present. Passengers on board will therefore experience one quarter, half or three quarters of their own body weight – depending on the trajectory,” explains Stang.

The goal of these flights is to see what effect partial gravity has on human muscle control.

For humans to be able to move around and interact with their environment, they require finely tuned muscle movements, to walk around or ensure a secure footing, for instance. Under partial gravity, in particular, they must be able to effectively control their muscles via their neural pathways. If we are unable to do so, the risk of stumbling is dramatically increased. This applies to both humans on Earth and astronauts in space. However, partial gravity conditions appear to influence this neuromuscular control in challenging situations, increasing the astronaut’s risk of stumbling. Researchers at the University of Freiburg are investigating why this is so. The results are intended to reduce the risk to astronaut safety during missions to other planets, thereby resolving a fundamental safety issue in human physiological space exploration.

This is better than nothing, but it seems to me to be the least important thing to study in partial gravity. The Apollo astronauts clearly demonstrated that humans can adapt their muscle movements to partial gravity. What we must instead learn is whether partial gravity will eliminate bone loss, loss of cardio-vascular conditioning, spinal changes, balance problems, and the vision damage, all of which have been found to occur in weighlessness.

At the same time, it is probably impossible to study any of these latter issues during a short parabolic vomit comet flight. The Germans are doing what they can. Unfortunately, they might be the only ones doing anything in this area.

House passes tiny $15 billion budget cut

11:06 pm

The corruption runs deep: House today passed, by the tiniest of margins, a minuscule $15 billion budget cut designed to make believe they are being fiscally responsible after their passage of a two year budget deal that added $300 billion of additional spending to the already bankrupt federal budget.

They will break their arms patting themselves on the back about this bill, even though they also know there is almost no chance this bill will make it through the Senate.

In other words, this is failure theater. After passing the bloated budget deal the Republicans in Congress went home to discover that the voters meant it when they said they wanted the budget slashed. They are now trying to manufacture a lie that says they are trying to cut the budget. They are lying however. They have no intention of trimming the budget. In this matter they are as corrupt as the Democrats.

And they wonder why we got Trump.

New texts from former FBI officials reveal contempt for Congress and the law

12:09 pm

Newly released and unredacted texts from former FBI officials Peter Strzok and Lisa Page not only reveal an effort to stonewall Congress from doing its Constitutionally-mandated oversight, they reveal an utter contempt for the law.

The article focuses on their contempt of Congress, but it really reveals that these two FBI agents, who now appear to be quite typical of much of the FBI’s upper management, were aggressively promoting a cover-up of illegal FBI actions and defying Congress in the process.

About a week after Comey’s press conference, Strzok wrote to Page that he was “Worried about work.” He was worried about “How much we decide to release, the prospect of second guessing.” It’s one thing if the second-guessing came from DoJ’s inspector general, but Strzok wasn’t about to be overseen by lawmakers: “The IG doing that bugs me;” Strzok texted, “Congress doing so infuriates me.”

He was doubly worried because, that day, Chaffetz and House Judiciary Committee Chairman Bob Goodlatte had sent a criminal referral to the U.S. Attorney for the District of Columbia asking that Hillary Clinton be investigated, and perhaps prosecuted, for perjury. For Strzok, the referral was yet another reason to withhold information requested by Congress: “You read the referral yet?” Strzok asks Page. “We really want to drop the LHM [a summary of an investigation called a Letterhead Memorandum] and 302s [FBI interview notes] into that environment?”

Page called the requests from the Hill, “insulting” and Strzok declared “I just have no faith in Congress to respect our investigative information. The LHM and no more. Not even senior people’s 302, unless what we’d release via foia [the Freedom of Information Act].”

Even when the FBI was cornered into making documents available, they did their best to hobble efforts to read them. Here’s Peter Strzok texting Lisa Page on August 16, 2016, the day the FBI finally turned over a single heavily redacted copy of the 302 notes of Hillary Clinton’s FBI interview: “I’m strongly opposed to making any more copies for Congress. We limited on purpose, After careful consideration. If they let any particular committee get the copy, tough. Let them sort it out.” [emphasis mine]

Peter Strzok very eloquently sums up their attitude in one later text: “F them.”

Contempt for Congress is perfectly reasonable. I actually agree with them here. Refusing to obey the orders of elected officials, however, is an abuse of power, is illegal, and at a minimum should have gotten them fired, immediately. Instead, the FBI leadership (Comey, McCabe, Rosenstein, etc) worked with them to defy Congress.

As I said yesterday, these people should also go to jail. They not only broke their oaths to defend and obey the Constitution, they participated in a criminal cover-up, in this case acting to protect the Democratic Party’s candidate for President from criminal prosecution.

Curiosity finds evidence of complex carbon molecules

11:40 am

In a study released today, the Curiosity science team announced that earlier drill samples revealed evidence of complex organic carbon molecules, the possible remains of past life.

To unlock organic molecules from the samples, the oven baked them to temperatures of between 600°C and 860°C—the range where a known contaminant disappeared—and fed the resulting fumes to a mass spectrometer, which can identify molecules by weight. The team picked up a welter of closely related organic signals reflecting dozens or hundreds of types of small carbon molecules, probably short rings and strands called aromatics and aliphatics, respectively. Only a few of the organic molecules, sulfur-bearing carbon rings called thiophenes, were abundant enough to be detected directly, Eigenbrode says.

The mass patterns looked like those generated on Earth by kerogen, a goopy fossil fuel building block that is found in rocks such as oil shale—a result the team tested by baking and breaking organic molecules in identical instruments on Earth, at Goddard. Kerogen is sometimes found with sulfur, which helps preserve it across billions of years; the Curiosity scientists think the sulfur compounds in their samples also explain the longevity of the Mars compounds.

Earth’s kerogen was formed when geologic forces compressed the ancient remains of algae and similar critters. It’s impossible to say whether ancient life explains the martian organics, however. Carbon-rich meteorites contain kerogenlike compounds, and constantly rain down on Mars. Or reactions driven by Mars’s ancient volcanoes could have formed the compounds from primordial carbon dioxide. Monica Grady, a planetary scientist at The Open University in Milton Keynes, U.K., believes the compounds somehow formed on Mars because she thinks it’s highly unlikely that the rover dug into a site where an ancient meteorite fell. She also notes that the signal was found at the base of an ancient lake, a potential catchment for life’s remains. “I suspect it’s geological. I hope it’s biological,” she says.

It must be emphasized once again that they have not found evidence of past life. What they have found are the types of molecules that are often left behind by life, but can also form without the presence of life.

This result, from past drillholes in the Murray Formation, explains however why Curiosity headed back downhill to do its most recent drill test.

Curiosity has one last tool to help the team find out: nine small cups containing a solvent that frees organic compounds bonded in rock, eliminating the need to break them apart—and potentially destroy them—at high temperatures. In December 2016, rover scientists were finally prepared to use one of the cups, but just then the mechanism to extend the rover’s drill stopped working reliably. The rover began exploring an iron-rich ridge, leaving the mudstone behind. In April, after engineers found a way to fix the drill problem, the team made the rare call to go backward, driving back down the ridge to the mudstone to drill its first sample in a year and half. If the oven and mass spectrometer reveal signs of organics in the sample, the team is likely to use a cup. “It’s getting so close I can taste it,” says Ashwin Vasavada, Curiosity’s project scientist at the Jet Propulsion Laboratory in Pasadena, California.

The newest drillhole sample has now entered the mass spectrometer. Stay tuned!

Movie of Juno’s thirteenth fly-by of Jupiter

10:12 am

Cool image time. Mathematician and software programmer Gerald Eichstädt has released another movie using images from Juno’s thirteenth close fly-by of Jupiter.

I have embedded the movie below the fold. As he notes,

The movie covers two hours of this flyby in 125-fold time lapse, the time from 2018-05-24T04:41:00.000 to 2018-05-24T06:41:00.000. It is based on 27 of the JunoCam images taken during the flyby, and on spacecraft trajectory data provided via SPICE kernel files.

The view begins by looking down at the northern hemisphere, and gets to within 2,200 miles of the giant planet’s cloud tops.

Rigged poll claims Americans want NASA to do climate research

10:00 am

A new Pew Research Center poll, that is getting lots of play in the press today and claims that Americans want climate research to be NASA’s number one purpose, appears very rigged to me.

First their main conclusion:

NASA oversees a diverse portfolio of space-related missions, from sending robotic probes to explore distant planets to launching satellites that study Earth’s atmosphere and oceans.

When asked to rate the importance of nine of these missions, majorities of Americans say a top priority for NASA should be monitoring key parts of the Earth’s climate system (63%) or monitoring asteroids and other objects that could potentially collide with the Earth (62%).

Slightly fewer than half of Americans (47%) believe that conducting basic scientific research to increase knowledge and understanding of space should be a top priority, with 40% saying such research is an important but lower priority.

…Missions for human astronauts to explore Mars and return to the moon are among NASA’s most high-profile programs. The Trump administration has expressed strong support for these initiatives, saying that exploring the solar system should be NASA’s core mission, beginning with a return of astronauts to the moon.

However, compared with other NASA programs, fewer Americans say such space exploration should be a top priority. Just 18% and 13%, respectively, say that sending astronauts to Mars or back to the moon should be a top priority; 37% and 44%, respectively, express the view that these missions are not too important or that NASA shouldn’t undertake these missions. [emphasis mine]

You can download the full report here [pdf].

While it is very possible that the high numbers for NASA climate research and low numbers for a NASA mission to the Moon or Mars reflect a growing skepticism about NASA’s ability to do space work, the poll itself simply isn’t trustworthy. Buried deep in Pew’s press announcement (three webpages down) was a graph that showed that, while the sample population surveyed was distributed reasonably in most ways, the numbers Republicans and Democrats polled was very skewed, 981 Republicans to 1,483 Democrats.

This is absurd. Every recent election has shown that the nation is very evenly split between these two parties. If anything, the results of the 2010, 2012, 2014, and 2016 elections would suggest there are more Republicans than Democrats. To favor Democrats by one third is simply dishonest and inaccurate. Even if they claim that they are merely polling Americans, not voters, the split shouldn’t be weighed that much in favor of Democrats.

Moreover, the poll shows how this skew warps the results, as it also admits that 78 percent of the Democrats polled love NASA’s climate research, while only 44 percent of Republicans do. The poll did find that both Democrats and Republicans had no interest in NASA’s deep space exploration plans, but once again, the poll did not ask why. I strongly suspect that NASA’s inability to get SLS launched explains this. No one believes the agency will ever do it.

With climate research the agency has an easier job, and has done better, but even here many Republicans have strong doubts, and would rather give the job to someone else.

It seems to me that the time has come to completely ignore political polling operations like Pew. They really have only one goal, and that is to push the Democratic Party’s political agenda.

New data widens the margin of error in carbon dating

5:21 pm

The uncertainty of science: New data suggests that the accuracy of carbon-14 dating, used mostly in archaeology and research covering the last few thousand years, has a wider margin of error than previously thought.

By measuring the amount of carbon-14 in the annual growth rings of trees grown in southern Jordan, researchers have found some dating calculations on events in the Middle East – or, more accurately, the Levant – could be out by nearly 20 years.

That may not seem like a huge deal, but in situations where a decade or two of discrepancy counts, radiocarbon dating could be misrepresenting important details.

To me, it seems somewhat arrogant for any scientist to assume this dating could be more accurate than this, especially going back several thousand years and especially considering the number of factors described in the article that they have account for and make assumptions about.

Nonetheless, documenting this margin of error means that the arrogant scientists of the future will have to include it in their research, rather than making believe it doesn’t exist.

Juno mission extended

3:31 pm

NASA has extended the Juno mission through 2022 in order to complete its planned science.

NASA has approved an update to Juno’s science operations until July 2021. This provides for an additional 41 months in orbit around Jupiter and will enable Juno to achieve its primary science objectives.Juno is in 53-day orbits rather than 14-day orbits as initially planned because of a concern about valves on the spacecraft’s fuel system. This longer orbit means that it will take more time to collect the needed science data.

An independent panel of experts confirmed in April that Juno is on track to achieve its science objectives and is already returning spectacular results.The Juno spacecraft and all instruments are healthy and operating nominally.

NASA has now funded Juno through FY 2022. The end of prime operations is now expected in July 2021, with data analysis and mission close-out activities continuing into 2022.

I will admit that though Juno is clearly learning a great deal about Jupiter, such as this story about lightning there, its larger orbit makes it difficult to track the gas giant cloud structures as they evolve. This is unfortunate.

8 times FBI colluded with Democrats during election

11:15 am

Link here. The author carefully summarizes what we now know about the partnership between the upper management at the FBI and CIA with the campaign of Hillary Clinton.

The intelligence bureaucracies spied on the Donald Trump campaign: Foreign Intelligence Surveillance Act warrants were granted because of a Hillary Clinton-funded and unverified document, national-security letters were issued to allow warrantless spying, and the unprecedented but not-illegal-per-se unmasking of Trump officials’ conversations with non-U.S. persons was shockingly routine.

Yet the news of a CIA-connected human source operating as far back as April or May of 2016 is about more than just spying. It is the latest example in what now looks to be a long line of attempted setups by the Clinton team, many times aided and abetted by our intelligence bureaucracies.

These events should anger any red blooded American who believes in representative democracy and the importance of the rule of law.

He then details eight examples, all well documented, where the leadership at the FBI and CIA worked hand-in-glove with the Democratic Party to help throw the election to Hillary Clinton, and failing that worked to invalidate the election results by trying to manufacture evidence that would justify removing Trump from office.

A large number of people should face prison terms for this. And it appears that at least one, former FBI deputy director Andrew McCabe, fears this possibility greatly.
