New data widens the margin of error in carbon dating
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
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
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.
More problems for James Webb Space Telescope?
The impending release of an independent NASA review of the state of the James Webb Space Telescope project suggests that the project is faced with additional issues.
NASA is in the process of evaluating the report from the Independent Review Board chaired by Tom Young to assess the status of the James Webb Space Telescope (JWST). Established in March, the Board was due to submit its report on May 31. NASA said today that the Board has completed its work and briefed NASA. The report will be released later this month after NASA determines the impact on cost and schedule.
Thomas Zurbuchen, NASA Associate Administrator for the Science Mission Directorate, created the Webb Independent Review Board (WIRB) on March 27, the same day he announced another delay in the telescope’s launch. WIRB held its first meeting the next week.
For many years, JWST appeared to be on track for launch in October 2018 after a 2011 restructuring that followed a series of earlier cost overruns and schedule delays. Congress capped the development cost (not operations) at $8 billion in law. Pursuant to the 2005 NASA Authorization Act, if a program exceeds 30 percent of its baseline estimated cost, NASA must notify Congress and no money may be spent on it after 18 months from the time of that notification unless Congress reauthorizes it.
The project will not die, Congress will simply extend it with lots more money. That is how big NASA projects really function, to take as long as possible so that they can continue their real goal of providing pork barrel jobs in congressional districts.
Democrats generally reject scientist candidates
In yesterday’s primary elections, scientists running as Democrats generally did poorly.
Science-minded candidates seeking seats in the next U.S. Congress took a drubbing from their Democratic opponents in yesterday’s raft of primary elections across the country.
Voters went to the polls Tuesday in eight states to choose nominees for the November elections. And none of the candidates who touted their scientific credentials—a list that includes volcanologist Jess Phoenix, technologist Brian Forde, pediatrician Mai Khanh Tran, and geophysicist Grant Kier—won their contested contests. In one California district, neuroscientist Hans Keirstead is trailing in a race that is still too close to call.
This article in the journal Science is fun to read in that it blatantly reveals that journal’s partisan Democratic Party leanings: the goal is to beat Republicans, and the hope was that scientists would do it. For the scientists however, it turns out that Democratic Party voters really don’t like science and the skeptical demands it requires.
Kind of reminds me of the secular liberal Jews who blindly vote Democratic, even as that party works to betray them.
Aerojet Rocketdyne completes first rocket engine for DARPA’s quick launch rocket
Aerojet Rocketdyne has completed assembly of the first rocket engine for DARPA’s quick launch rocket, Phantom Express, being built by Boeing.
[The engine] can fly for 55 missions with servicing only every 10. To speed up turnarounds, the engines will be installed in a hinged nacelle for better access and the entire spacecraft will use an operations procedure similar to those developed for aircraft.
The first AR-22 engines will be used for daily hot-fire tests at Rocketdyne’s Stennis Space Center facility in Mississippi to demonstrate that it can handle multi-mission conditions and that the fast turnarounds are both feasible and practical. In addition, Rocketdyne says that the test information will help spaceplane builder Boeing to improve the Phantom Express ground infrastructure.
Boeing and Aerojet Rocketdyne both have it very sweet. They have gotten DARPA to fund the development of their own low-cost reusable rocket, while other private companies have to go it alone.
Still, it appears that Boeing is leveraging its engineering experience from building the X-37B for the Air Force for this project. Whether the company can expand the rocket’s customer base beyond the Air Force remains unclear.
Northrop Grumman purchase of Orbital ATK approved
Capitalism in space: Northrop Grumman’s acquisition of Orbital ATK has been approved by the Federal Trade Commission.
With this purchase, the name Orbital ATK will recede into history. This division of Northrop Grumman will now be called Northrop Grumman Innovation Systems. Here at Behind the Black I will simple call it Northrop Grumman.
The FTC ruling carried with it one caveat:
As a condition for the approval of the merger, the company will have to supply solid rocket motors “on a non-discriminatory basis under specified circumstances,” the FTC ruled.
Ensuring competition in the solid rocket motors industry is a key issue for the Defense Department because only two manufacturers remain in the business, Orbital ATK and Aerojet Rocketdyne. The Air Force plans to acquire a new strategic intercontinental ballistic missile, the so-called Ground Based Strategic Deterrent, with Northrop Grumman and Boeing competing for the award. The intent was for both Orbital ATK and Aerojet to supply both prime contractors. The FTC decision requires Northrop Grumman to separate its solid rocket motors business with a firewall so it can continue to support Boeing.
It will be up to the Defense Department to ensure compliance with the firewall mandate.
It is unclear from the press report what this firewall accomplishes. It sounds like there was fear that Northrop Grumman would not have sold its solid rocket boosters to competitor Boeing, but I don’t see that happening. This acquisition was designed to put Northrop Grumman back in the rocket business just as that business is booming. Part of that business is selling solid rockets.
Either way, the company that David Thompson started in the early 1980s to challenge the big space companies, Orbital Sciences, has now completely vanished into one of those big space companies.
China offers big bucks to attract foreign science talent
Link here. In China’s recent push to build big science facilities, such as the giant radio telescope FAST, it has faced a shortage of qualified homegrown Chinese scientists to run those new facilities.
To solve this problem, China is now offering big bucks to any scientist, even foreigners, willing to move to China.
On 22 May, the Ministry of Science and Technology issued guidelines that encourage science ministries and commissions to consult foreign experts and attract non-Chinese to full-time positions within China. In a striking change, foreign scientists are now allowed to lead public research projects.
In the past decade, China has aimed to build up its scientific capacity by luring back some of the tens of thousands of Chinese scientists working abroad. The latest measures emphasize that non-Chinese talent is also welcome. Drafted in December 2017 but not previously made public, they are “a confirmation of things that have been going on for a while,” says Denis Simon, an expert on China’s science policy at Duke Kunshan University in China, a branch campus of the Durham, North Carolina–based Duke University.
Simon says foreign scientists are drawn by China’s increased spending on R&D, which is rising twice as fast as its economic growth. Increasingly ambitious big science projects, such as a massive particle accelerator now under study, are a lure as well, says Cao Cong, a science policy specialist at the University of Nottingham Ningbo in China, an affiliate of the U.K. university. The opportunity for foreign scientists to serve as principal investigators for publicly funded programs is a significant new incentive, says Liang Zheng, who studies science and technology policy at Tsinghua University in Beijing.
Of course, moving to a nation ruled under totalitarian communist rule has its drawbacks:
Relocating to China comes with challenges. Gibson teaches in English but needs Chinese language help handling administrative matters and grant applications. Restricted access to internet sites such as Google is also a hurdle. “My research and my teaching regularly rely on access to online resources and search platforms [that are] blocked in China, so this is an impediment to my work,” Gibson says. But he has found workarounds. China shut down many virtual private networks, which provide access to blocked overseas sites, but a few remain. “There’s a saying: ‘Everything in China is difficult, but nothing is impossible,’ which I think reflects the situation very accurately,” Gibson says.
I would also expect that any American who makes this move will face significant security problems with the U.S. government upon their return.
