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.

Lecture by atheist/scientist Richard Dawkins canceled in Berkeley because he criticized Islam

10:41 am

Fascist Berkeley: A lecture at a Berkeley church for a local leftwing radio station by atheist and scientist Richard Dawkins was canceled when the station learned he had posted some tweets criticizing Islam.

Essentially, the left can’t tolerate any dissent of any kind, and will destroy itself and everyone else if we continue to allow it to grow and gain power.
