Anti-vaccine campaigns are threatening the return of measles

8:09 pm

The coming dark age: The ignorant and mindless campaigns against vaccination is making it more likely that the U.S. will see a return of major measles epidemics.

Researchers Nathan Lo and Dr. Peter Hotez were motivated to conduct the study after seeing data showing growing vaccine hesitancy and use of non-medical exemptions—largely due to lies and misinformation about the safety of vaccines and the threat of devastating diseases, such as measles. Currently, about two percent of kids aged two to 11 have a non-medical vaccine exemption.

Measles, in particular, requires vigilant vaccination. The highly infectious virus can linger in the air for hours after a cough or sneeze. Those sickened develop high fevers, rashes, inflamed eyes, and cold-like stuffy nose and cough. But people can spread the infection days before those symptoms appear. About 30 percent develop complications, such as pneumonia, brain swelling, and blindness.

To thwart infections, a population must have between 90- and 95-percent vaccine coverage to maintain herd immunity. Many communities and counties in the US are already on the brink of dipping below that range and thereby losing their protection from a case of measles going, well, viral. And there’s room for those vaccination rates to continue to slip. Presently, 18 states allow for personal belief exemptions, and all but two states allow for religious or philosophical exemptions.

They of course propose forcing people to get their kids vaccinated. I say, if you have kids, you have the responsibility to get informed and get them vaccinated, instead of taking advice from uneducated television stars who know nothing about science and doctors who have had their licenses revoked.

Commercial lunar mission gives launch contract to ULA

5:56 pm

Capitalism in space: Astrobotic, a private company planning to put a lander on the Moon by 2019, has awarded its launch contract to ULA.

This initial Peregrine lunar lander will fly 77 pounds (35 kilograms) of customer payloads from six nations either above or below the spacecraft’s deck, depending on specific needs. The autonomous landing will use cameras, guidance computing and five Aerojet Rocketdyne-made hypergolic engines to set the lander down on four shock-absorbing legs.

It will stand 6 feet tall (1.8 meters) and have a diameter of 8 feet (2.5 meters).Subsequent missions envision scaling up to payload masses of 585 pounds (265 kilograms). Markets range from scientific instruments to placing mementos on the Moon.

This company had been competing for the Google Lunar X-Prize, but pulled out of the competition when it realized it couldn’t launch by the end of 2018. It continued development, however, and apparently has gathered enough customers to pay for its launch in 2019.

TDRS-M launch moved to August 20

5:47 pm

NASA has decided to delay the launch of its TDRS-M satellite until August 20.

This simplifies their launch schedule, as it allows SpaceX to launch as planned on August 12 and thus not interfere with an August 17 Russian spacewalk that is releasing two satellites from ISS. It will also give them plenty of time to replace the antenna that was damaged during launch prep, in an incident which they still have not described in any detail.

Repeal of Obamacare fails in Senate

2:07 pm

Not surprisingly, a clean not-quite-full repeal of Obamacare failed today in the Senate, 45 to 54.

As expected, every Democrat voted to endorse their failed law. They were aided by seven fake Republicans who should all be challenged in primaries. These were Susan Collins of Maine, Dean Heller of Nevada, Shelly Moore Capito of West Virginia, Lisa Murkowski of Alaska, Lamar Alexander of Tennessee, John McCain of Arizona, and Rob Portman of Ohio.

A lot of pundits are going to claim that this failure to repeal is a betrayal of the Republican Party. I actually don’t see it as that. Had Mitch McConnell not allowed this vote I might have agreed, but he did allow it, thus forcing those from both parties who support Obamacare to go on record. We now know who those people are.

The real problem is that too many people in the U.S. no longer believe in freedom, instead want a government hand out, and have thus elected legislators (from both parties) who are only too happy to give it to them in exchange for power and wealth. If we are going to get rid of this bad law, as well as many other bad leftwing government policies, we need to vote these specific people out of office.

Computer simulations prove that we can geoengineer the climate!

9:34 am

What could possibly go wrong? Global warming scientists have discovered, using computer simulations, that combining several different geoengineering techniques, what they call a “cocktail,” will save the planet and do no harm.

The team—which includes Carnegie’s Ken Caldeira, Long Cao and Lei Duan of Zhejiang University, and Govindasamy Bala of the Indian Institute of Science—used models to simulate what would happen if sunlight were scattered by particles at the same time as the cirrus clouds were thinned. They wanted to understand how effective this combined set of tools would be at reversing climate change, both globally and regionally. “As far as I know, this is the first study to try to model using two different geoengineering approaches simultaneously to try to improve the overall fit of the technology,” Caldeira explained.

The good news is that their simulations showed that if both methods are deployed in concert, it would decrease warming to pre-industrial levels, as desired, and on a global level rainfall would also stay at pre-industrial levels. But the bad news is that while global average climate was largely restored, substantial differences remained locally, with some areas getting much wetter and other areas getting much drier.

And if you believe that this simulation captures what will really happen should global warming scientists dump vast amounts of light-reflecting particles in the upper atmosphere while also adding chemicals to thin cirrus clouds, I have a bridge in Brooklyn I want to sell you. We don’t even really know if the climate is warming as these political activists (they are not really scientists) claim. We don’t really understand how the climate actually works. We don’t even understand fully how the Sun really fluctuates, and it is without doubt the climate’s most important influence. And these guys claim they now know what will happen if we play god with the atmosphere? Give me a break.

The damage and repair of TDRS-M creates complicated scheduling problems

9:10 am

Because of the launch delay caused by the accident that damaged the antenna of NASA’s TDRS-M communication satellite, requiring its replacement, the agency is now faced with a cascading series of scheduling problems.

They are now aiming for an August 10 launch of TDRS-M on a ULA Atlas 5. This will then force a delay in the August 12 launch of a Dragon capsule to ISS to August 14, which can’t be delayed past August 16 because of a scheduled Russian spacewalk on ISS that must happen on August 17 because it involves the release of two satellites. Making things even more complicated is Dragon’s cargo, which includes mice for a rodent experiment. If it doesn’t occur before August 16, the mice will then have to be replaced with fresh mice, causing further delays.

There is then even the chance that these scheduling problems might impact SpaceX’s scheduled August 28’s launch of the X-37B, as well as ULA’s scheduled August 31 launch of surveillance satellite.

One additional tidbit: This Dragon will be the last unused cargo capsule. All future SpaceX cargo missions will use previously flown capsules.

I should add that these scheduling issues illustrate starkly the growing need for more launch sites. There is money to be made here, fulfilling this need.

Interorbital’s first test rocket, Neptune 1, is almost ready for flight

8:56 am

Capitalism in space: Interorbital, a smallsat rocket company building what they hope will be the world’s smallest and cheapest rocket, have announced that their first test rocket, Neptune 1 Guidance Test Vehicle (N1 GTV), is nearing completion.

During the test flight, the rocket will simulate an orbital launch trajectory by using the main rocket engine’s throttling capability to vary the thrust-to-weight ratio, thus simulating the actual conditions that will be experienced during an orbital launch. After the rocket passes through the transonic phase and Max Q, the engine will gradually throttle down, slowing the rocket until it begins to hover. At this point, the rocket engine will be shut down and the rocket will be allowed to fall. At a safe altitude, a parachute will be deployed for vehicle and payload recovery.

They then plan to follow this with an orbital test flight. No dates however for any of these test flights have as yet been announced.

Astronomers find unexpected comets in outer reaches of solar system

11:49 am

Using data from the WISE space telescope, astronomers have found that there are more comets lurking in the far reaches of the solar system than they had predicted.

Scientists found that there are about seven times more long-period comets measuring at least 0.6 miles (1 kilometer) across than had been predicted previously. They also found that long-period comets are on average up to twice as large as “Jupiter family comets,” whose orbits are shaped by Jupiter’s gravity and have periods of less than 20 years. Researchers also observed that in eight months, three to five times as many long-period comets passed by the Sun than had been predicted.

These are comets whose orbits never allow them to come close to the inner solar system, which allows them to remain puffy and large.

The endless bands of Saturn

9:39 am

Cool image time. One of the images released by the Cassini science team this week when it announced the first results from the spacecraft’s weekly dives between Saturn and its innermost rings was a short video made from 137 images taken on its first dive on April 26, 2017.

It is absolutely worthwhile to view this video. It begins at Saturn’s north pole, looking down into what appears to be a bottomless vortex, and continues south to almost the equator. Along the way the movie captures what seems to be innumerable horizontal bands across the gas giant’s surface. Not only are do we see the major bands that have been observed from Earth for centuries, there are bands within bands, and bands within those bands. Like a fractal it appears that the deeper you go, the more horizontal jet streams you see.

Like Juno at Jupiter, the mysteries of a gas giant like Saturn is overwhelming. This is a big and very active planet. We understand almost nothing about its weather systems, its atmosphere, and its interior. And this glimpse by Cassini is only that, a mere glimpse. When Cassini’s mission ends in September, it will leave us a treasure trove of knowledge. It will also leave us a much larger library of unanswered questions, all of which will remain unanswered until we can return, decades hence, with new probes..

Tupperware in space!

9:20 am

Capitalism in space: Tupperware and NASA have partnered to provide space-grown gardens an artificial material for roots to grow and be watered.

First flown to the ISS in 2014, the Vegetable Production System, (aka the “Veggie” facility), is an experiment for growing plants in zero gravity in a plastic greenhouse. It consists of a collapsible plastic tent with a controllable atmosphere lit by red, blue, and green LED lamps to promote growth. Since dirt and space travel don’t mix, the seeds are embedded in rooting “pillows” that take the place of soil to retain water and give the roots somewhere to grow.

The problem is that the pillows don’t hold onto water very well, so the hydroponic system keeps drying out unless it’s tended regularly. Given how much it costs to keep an astronaut on the station, time spent watering the lettuce is about as economical as hiring a brain surgeon to mow the lawn, so a team led by Howard Levine at the Kennedy Space Center is working on some upgrades for the system.

One key example is the semi-hydroponic Passive Orbital Nutrient Delivery System (PONDS) being produced by Tupperware. With over 75 years of experience working with food-grade plastics as well as injection molding and other plastic manufacturing processes, Tupperware is producing a new disposable pillow made of plastic mesh that uses capillary forces and unusual geometries to replace gravity and hold water in like a zero gravity sponge while permitting root formation.

In other words, rather than design and built the pillows itself, as it would have in the past, NASA has hired Tupperware to build them. I am willing to bet this is saving NASA both time and money.

New Horizons team spots stellar eclipse by 2014 MU69

9:14 am

In an effort to learn as much as possible about New Horizons’ next target, Kuiper belt object 2014 MU69, the science team has successfully observed on July 17 a 0.2-second-long eclipse of a star by that object.

This was the third occultation by 2014 MU69 that the science team attempted to catch. With the first, on the ground, they saw nothing. The second, using the flying observatory SOFIA, was more successful, as was the third attempt last week.

Though they haven’t yet released their findings, they say the data from the last two observations has allowed them to determine the rough shape and size of 2014 MU69. This is crucial information needed for planning the observations of it during New Horizons January 1, 2019 fly-by.

Another space company partners with Luxembourg

9:03 am

Capitalism in space: Luxembourg has formed a new business partnership with Magna Parva, a United Kingdom company, to develop in-space manufacturing technology.

Within the framework of this MoU, the developments and research to take place in Luxembourg are related to the project for in-space manufacturing of composite beams equipped with antennas. Kleos Space will collaborate with EmTroniX, a Luxembourg-based company specialized in electronics development, as well as with the Luxembourg Institute of Science and Technology (LIST) on this subject. The Government will support the development of the in-space manufacturing technology by providing funding through the Luxembourg space program (LuxIMPULSE).

I suspect the manufacturing will be some form of 3D printing. However, it is unclear to me where in space this manufacturing will take place. Will it occur on ISS or the Chinese space station expected to launch in a few years? Or is Luxembourg planning some new venture that either includes some privately built station (Bigelow?) or an unmanned robot in orbit?

Either way, Luxembourg is once again investing its tax revenue in what it thinks will be profitable endeavors in space, and that venture capitalism is continuing to attract companies to that nation.

Brooks and Dunn – Only in America

6:01 pm

An evening pause: In honor of what happened today, 48 years ago, when three American astronauts safely landed home on Earth, after walking on the Moon. From the chorus:

Only in America
Dreamin’ in red white and blue
Only in America
Where we dream as big as we want to
We all get a chance
Everybody gets to dance

It will be the American ideas of freedom, individual achievement, and capitalism that will make the settlement of the solar system possible. Other nations will participate, but it will still be these ideas that fuel the journey.

Hat tip Jim Mallamace.

California iman calls for genocide against all Jews

4:06 pm

Can’t we all just get along? The Friday sermon of a California iman called for the killing of all Jews because Israel had the nerve to put up metal detectors at the entrances to the Temple Mount in Jerusalem.

And why did Israel do this? Because three Arabs murdered two Israeli policemen in cold blood at the site.

The bottom line here is that the Islamic world wants to kill Jews, and will find any excuse to do it, even excuses as silly as an Israel effort to prevent further violence. Listen to this guy’s sermon at the link. He makes it very clear that this is a Muslim requirement — from the Koran — to kill Jews. And Israel should negotiate with these fanatics?

I want to also point out that this iman was making his speech in California, a place that increasingly fashions itself a haven for fascists and the power-hungry. Note also these details about the mosque from which he made this speech:

The Islamic Center of Davis in Northern California is located about 15 miles from the state’s capital, Sacramento. It has, in the past, hosted events featuring Waleed Idris al-Menessey, who has also called for Muslims to kill Jews and impose Sharia law on non-Muslims law worldwide. Al-Meneesey’s Minneapolis-based Islamic center has produced five recruits for the Islamic State terrorist organization. On its online resources page, the Islamic Center of Davis links to several known Muslim Brotherhood front groups, such as the Council on American-Islamic Relations (CAIR), the Islamic Society of North America (ISNA), and the Muslim Students Association (MSA).

If I, a Jew, lived in Sacramento I would not feel safe.

Facebook moves to protect Islam from criticism

12:02 pm

Even while Facebook and Twitter allow violent threats to be posted against critics of Islam, the sites are moving to censor and block posts by those critics.

What happened on that day was that Facebook and Twitter began to censor Jihad Watch as “hate speech,” in accordance with the assurances they had given to the European Union.

Facebook, immediately after concluding an agreement with the European Union, began moving aggressively against foes of jihad terror and mass Muslim migration in the West. Nina Rosenwald, the president and founder of the conservative think tank Gatestone Institute, on June 2, 2016 recorded Facebook’s haste to implement the new speech regulations: “On Tuesday, the European Union (EU) announced a new online speech code to be enforced by four major tech companies, including Facebook and YouTube. On Wednesday, Facebook deleted the account of Ingrid Carlqvist, Gatestone’s Swedish expert.”

Carlqvist’s crime, according to Rosenwald, was to take note of real crimes by Muslim migrants: “Ingrid had posted our latest video to her Facebook feed—called ‘Sweden’s Migrant Rape Epidemic.” In that video, said Rosenwald, “Ingrid calmly lays out the facts and statistics, all of which are meticulously researched.” Rosenwald added that the video was adapted from a “research paper that Gatestone published last year. The video has gone viral—racking up more than 80,000 views in its first two days. But the EU is quite candid: it is applying a political lens to their censorship…. ”

This is just one example. The article gives others, including examples where death threats against Islam’s critics are allowed to remain online.

Just one of many reasons I will have nothing to do with Facebook or Twitter.

First results from Cassini’s dives between Saturn and its rings

11:35 am

The first results from Cassini’s weekly dives between Saturn and its innermost rings have now been released.

The big surprise so far is the lack of a tilt to Saturn’s magnetic field.

Based on data collected by Cassini’s magnetometer instrument, Saturn’s magnetic field appears to be surprisingly well-aligned with the planet’s rotation axis. The tilt is much smaller than 0.06 degrees — which is the lower limit the spacecraft’s magnetometer data placed on the value prior to the start of the Grand Finale.

This observation is at odds with scientists’ theoretical understanding of how magnetic fields are generated. Planetary magnetic fields are understood to require some degree of tilt to sustain currents flowing through the liquid metal deep inside the planets (in Saturn’s case, thought to be liquid metallic hydrogen). With no tilt, the currents would eventually subside and the field would disappear.

Any tilt to the magnetic field would make the daily wobble of the planet’s deep interior observable, thus revealing the true length of Saturn’s day, which has so far proven elusive.

They also have gotten lots of much better images of the planet’s cloud tops.

Fake “Star Wars” science paper accepted/published by four journals

10:16 am

Peer-review science at its best! A fake science paper, loaded with quotes and references to the Star Wars movies, has been published or accepted for publication by four medical journals.

A neurology expert has revealed they were able to convince a trio of medical journals to publish their Star Wars-themed ‘fake’ manuscript, despite it being packed full of references to George Lucas’ iconic series. The author, who writes online under the name Neuroskeptic, said their paper titled ‘Mitochondria: Structure, Function and Clinical Relevance’ was poorly written and ‘an absurd mess of factual errors, plagiarism and movie quotes’.

‘I wanted to test whether ‘predatory’ journals would publish an obviously absurd paper,’ the hoax’s author wrote for Discover Magazine. ‘So I created a spoof manuscript about “midi-chlorians” – the fictional entities which live inside cells and give Jedi their powers in Star Wars. I filled it with other references to the galaxy far, far away, and submitted it to nine journals under the names of Dr Lucas McGeorge and Dr Annette Kin.’

The name of the authors given in the fake piece are thinly-veiled references to Lucas – Star Wars’ creator – and Anakin Skywalker. Neuroskeptic went on in their blog post to explain the paper was picked up by four different journals – the American Journal of Medical and Biological Research, the International Journal of Molecular Biology: Open Access, the Austin Journal of Pharmacology and Therapeutics, and American Research Journal of Biosciences. The AJMBR did not publish the paper but did request a $360 fee in order to do so.

That this keeps happening suggests that much of what is published in peer-review journals is equally bad, and should never see the light of day. The bad work gets published because the journals make their money by charging the scientists to publish things, and the scientists need to get in print to justify their cushy jobs in academia. Sadly, no one seems to care whether they can teach.

R.I.P. U.R. Rao

10:01 am

U.R. Rao, the man who led the design and construction of India’s first satellite in 1975, has passed away at 85.

After graduation from Madras University and post-graduation from Banaras Hindu University, Rao went to the US in the early 1960s to work in the faculty of MIT (Massachusetts Institute of Technology) at Cambridge in Maryland and as an Assistant Professor at University of Texas in Dallas.

On returning to India in 1966, Rao joined PRL in Ahmedabad as professor under the guidance of Vikram Sarabhai, architect of the Indian space science, and shifted to Bengaluru to work as a space scientist at ISRO’s satellite centre in 1972. “Under Rao’s guidance, the first Indian satellite ‘Aryabhata’ was built in 1975 to use space technology for the country’s socio-economic development. On its success, about 20 satellites were developed and launched for various space applications spanning communications, remote sensing and weather under his supervision,” an official said.

He subsequently became head of ISRO from 1984 to 1994, when they developed their first rocket, the ASLV, which became today’s PSLV, as well as began their development of the GSLV.

NASA and Lockheed Martin to build simulated interplanetary spaceship, on the ground

9:53 am

Yawn. NASA and Lockheed Martin have partnered to re-purpose a leftover shuttle cargo module into a ground-based simulated interplanetary spaceship.

Lockheed Martin announced it will refurbish the Donatello multi-purpose logistics module (MLPM), transforming from it from its original, unrealized role as a supply conveyor for the International Space Station to a test and training model of a living area for astronauts working beyond Earth orbit. The work is being done under a public-private partnership between the aerospace corporation and NASA. “We are excited to work with NASA to repurpose a historic piece of flight hardware,” said Bill Pratt, Lockheed Martin’s program manager for the deep space habitat contract, in a statement.

…Over an 18-month period, Lockheed Martin will build upon its deep space habitat concept it developed during the first phase of NASA’s Next Space Technologies for Exploration Partnerships, or NextSTEP, program by using virtual and augmented reality prototyping in an effort to reduce costs and schedule, as well as identify and address issues while early in the design process. The results, to be shared with the space agency, will help to further understanding of the systems, standards and interfaces needed to make living in deep space possible.

This is nice, but it is essentially make-work for Lockheed Martin and a waste of money. At this stage of our engineering knowledge, we need to fly our interplanetary spaceship prototypes. Building them on the ground can only provide a limited amount of new knowledge, much of which has already been learned from numerous very similar past ground-based experiments.

For example, why isn’t NASA and Lockheed Martin also partnering with SpaceX, contracting to fly Donatello on the Falcon Heavy? That makes a lot more sense, and would not cost a lot of additional money. In fact, it might be quite cheap, since SpaceX needs customers willing to gamble on its new heavy-lift rocket.

Schedule for commercial manned flights solidifies

5:54 pm

Capitlism in space: It appears that the schedule for the first unmanned and manned test flights of the commercial capsules being built by SpaceX and Boeing is getting more certain.

The latest SpaceX schedule calls for an uncrewed test flight in February 2018, followed by a crewed test flight in June 2018. Boeing’s schedule anticipates an uncrewed test flight in June 2018 and a crewed test flight in August 2018.

While this sounds encouraging, the story contradicts a Boeing report last week that suggested their first manned flight would be delayed into the fourth quarter of 2018. Both stories however pin the first unmanned demo flight for June 2018, which now seems to be a firm date.

California community colleges consider eliminating algebra requirement

1:32 pm

The coming dark age: Because algebra is hard for many minority students, the California community college system is considering eliminating their algebra requirement.

“The second thing I’d say is yes, this is a civil rights issue, but this is also something that plagues all Americans — particularly low-income Americans,” [said Eloy Ortiz Oakley, chancellor of the California community college system.] If you think about all the underemployed or unemployed Americans in this country who cannot connect to a job in this economy — which is unforgiving of those students who don’t have a credential — the biggest barrier for them is this algebra requirement. It’s what has kept them from achieving a credential.”

Hey, Chancellor Oakley, you know that you are implying that blacks and minorities are not capable of understanding algebra.

Meanwhile I, as a conservative, instead think that if we demand them to do better, they will do better.

So who’s the racist?

NYC law bans pet sitting without license

1:23 pm

You get the government you deserve: The New York City health department has been fining pet sitters and trying to block online services that link pets to sitters because the city law bans pet sitting without a kennel license as well as bans issuing that license to private homes.

Health Department rules ban anyone from taking money to care for an animal outside a licensed kennel — and the department has warned a popular pet-sitting app that its users are breaking the law.

“The laws are antiquated,” said Chad Bacon, 29, a dog sitter in Greenpoint, Brooklyn, with the app Rover. “If you’re qualified and able to provide a service, I don’t think you should be penalized.”

I must admit that I have very little sympathy for these pet sitters. New Yorkers have been voting for a big intrusive city government for more than a century. This is what they wished for. This is what they get. Nonetheless, while it might make sense for the local government to place limits on the number of pets allowed in a private home in a crowded place like New York, for it to ban anyone from earning any money for taking care of someone else’s pets is a clear abuse of power.

Is the Arctic icecap now larger than in 1971?

11:37 am

This story compares a 1971 National Geographic map of the Arctic Ocean and its icecap with modern satellite data, and finds that the icecap is actually significantly larger now.

Take a look. Then come back to read my analysis.

Back? Okay. First, we are presently in the midst of summer in the Arctic, so the icecap shown on the modern map should shrink somewhat this year. Second, it is not clear what time of year the National Geographic map portrays. Is it maximum ice during the winter? Or they average for the year?

These questions however avoid the bigger point here, which is that there doesn’t really appear to be any significant change overall to the Arctic icecap in the past half century. The icecap had seen some major shrinkage during the first decade of the 21st century, but in recent years it has begun recovering. So much for the many past predictions by global warming activists that the Arctic will be ice free in summer because of global warming, by 2008, 2014, or 2018.
