ISEE-3 fires its thrusters for the first time since 1987.

The private team resurrecting the 1970s space probe ISEE-3 successfully fired its thrusters for the first time since 1987.

It took several attempts and days to perform the roll maneuver because ISEE-3 was not responding to test commands. But this time, controllers got in touch. They increased the roll rate from 19.16 revolutions per minute to 19.76 RPM, putting it within mission specifications for trajectory corrections.

The spacecraft is now prepped for the big burn that will change its trajectory.

Two exoplanets disappear

The uncertainty of science: Two exoplanets orbiting Gliese 581, both thought to be in the habitable zone, have now been proven to not even exist.

“We’ve proven that some of the controversial signals from Gliese 581 don’t come from two proposed Goldilocks planets, but instead are coming from activity within the star itself masquerading as planets,” lead study author Paul Robertson, an astronomer at Pennsylvania State University in University Park, told Space.com.

This result should serve as a strong reminder: Though it is likely that many if not most of the so far discovered exoplanets are real, it is also likely that many will turn out to be false positives. We won’t have solid real knowledge about them until we can actually get a close look at them, which will require far better telescopes in space, and maybe even interstellar missions to them.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Telescope teamwork produces spectacular galaxy image

M106

Combining images from a host of space and ground-based telescopes, astronomers have created a spectacular image of the galaxy M106.

This galactic fireworks display is taking place in NGC 4258 (also known as M106), a spiral galaxy like the Milky Way. This galaxy is famous, however, for something that our Galaxy doesn’t have – two extra spiral arms that glow in X-ray, optical, and radio light. These features, or anomalous arms, are not aligned with the plane of the galaxy, but instead intersect with it.

The anomalous arms are seen in this new composite image of NGC 4258, where X-rays from NASA’s Chandra X-ray Observatory are blue, radio data from the NSF’s Karl Jansky Very Large Array are purple, optical data from NASA’s Hubble Space Telescope are yellow and blue, and infrared data from NASA’s Spitzer Space Telescope are red.

A new study of these anomalous arms made with Spitzer shows that shock waves, similar to sonic booms from supersonic planes, are heating large amounts of gas – equivalent to about 10 million Suns. What is generating these shock waves? Radio data shows that the supermassive black hole at the center of NGC 4258 is producing powerful jets of high-energy particles. Researchers thinkthat these jets strike the disk of the galaxy and generate shock waves. These shock waves, in turn, heat some of the gas – composed mainly of hydrogen molecules – to thousands of degrees.

The astronomers also used the Herschel Space Observatory to confirm the data from Spitzer.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount.

Newly discovered dinosaur tracks

A cluster of dinosaur tracks discovered recently in Alaska has revealed to paleontologists a wealth of new information about their behavior.

The thousands of impressions, created on a 180-meter-long portion of near-coastal flood plain, today pepper a steep mountainside. Most of the tracks, made somewhere between 69 million and 72 million years ago, were left by hadrosaurs, commonly known as duck-billed dinosaurs (the crested creatures in this artist’s representation).

The consistent and excellent preservation of tracks suggests all the footprints were created within a short time period. Varying in width from 8 to 64 centimeters, the footprints cluster within four distinct size ranges, which researchers suggest represent specific age groups within a multigenerational herd. About 84% of the tracks were made by adult and near-adult hadrosaurs and 13% by young presumed to be less than 1 year old. A mere 3% of the tracks represent juvenile hadrosaurs, a rarity that strongly suggests the young of this species experienced a rapid growth spurt and therefore spent only a short time at this vulnerable size, the researchers report online this week in Geology.

Gigantic underground trampoline about to open

Want to have some fun? An amusement park in Northern Wales is about to open a gigantic underground trampoline ride to the public..

Battle Below is located deep within a 100 ft (30.5 m) deep and 60 ft (18.3 m) wide disused mine. The new site features three large trampolines stretching across the cave-like mine walls and are positioned at varying heights. The trampolines are linked together by 60 ft (18.3 m) slides and a spiraling staircase. Adding to the atmosphere, multi-colored LED lights have been installed throughout the mine, which project onto the walls of the cavern.

It took over a kilometer of nett and 4,500 man hours to complete the underground trampolines, which can accommodate 100 bouncing visitors at a time. Patrons are required to wear protective gear, including overalls and a helmet before gaining access to the site via an old mining train. They’re also encouraged to bounce as high as they dare, potentially reaching a maximum height of 80 ft (24 m).

Bounce Below opens on July 4, with tickets starting from ÂŁ15 (about US$25) per person.

NASA and Boeing finalize contract to build the SLS rocket

NASA and Boeing today signed a $2.8 billion contract for Boeing to build the core stage of the SLS rocket

Scheduled for its initial test flight in 2017, the SLS is designed to be flexible and evolvable to meet a variety of crew and cargo mission needs. The initial flight-test configuration will provide a 77-ton capacity, and the final evolved two-stage configuration will provide a lift capability of more than 143 tons.

It would be nice for the U.S. to have this heavy-lift rocket, but I fully expect the funds to run out immediately after it makes its inaugural flight, despite the wonderful pork it provides to so many Congressional districts. It just costs too much per launch.

Russia abandons Sea Launch

Running from competition: The Russian space agency Roskosmos has decided not to spend the money necessary to buy Sea Launch and make it part of its consolidated United Rocket and Space Corporation (URSC).

Part of the reason the Russians are abandoning Sea Launch is that the rocket the ocean-going platform uses is the Ukrainian-built Zenit rocket, and Russia wants URSC to a wholly Russian operation. Rather than partner with Ukraine for profit, they will let the business die.

SpaceX’s Falcon Heavy rocket gets a customer

The competition heats up: The commercial satellite company Inmarsat has booked SpaceX’s Falcon Heavy rocket for one firm launch and two additional options.

The firm contract is for the launch, scheduled perhaps aggressively for late 2016, of a satellite being built for both Inmarsat and Arabsat of Riyadh, Saudi Arabia. Arabsat will use the satellite for conventional telecommunications services for its wholly owned Hellas-Sat fleet operator of Greece. The Inmarsat payload uses S-band to provide mobile communications in Europe as part of a satellite-terrestrial broadband network, which is a new business line for Inmarsat.

Inmarsat’s launch contract is for a rocket that has not even yet been tested once, which tells us something about the faith they have in SpaceX. While I would be shocked if they didn’t have an option to pull out should there be significant delays or problems in launching Falcon Heavy, that they are willing to commit to it now is a convincing endorsement of SpaceX.

FIRE sues to end university speech codes

Pushback: The Foundation for Individual Rights in Education (FIRE) today filed lawsuits against the speech codes at four universities.

Read the article. The specific examples are quite oppressive. For example:

At Citrus College in California, student Vincenzo Sinapi-Riddle is challenging three unconstitutional policies, including a free speech zone that the school already agreed to abolish after a 2003 lawsuit. Not only did Citrus College reinstitute its “Free Speech Area,” comprising a miniscule 1.37% of campus, but it also requires student organizations to undergo a two-week approval process for any expressive activity.

More fraud in peer-reviewed science

The science journal Nature today announced the retraction of two controversial stem cell papers.

The two papers reporting the stimulus-triggered acquisition of pluripotency (STAP) phenomenon appeared online on 29 January. Questions about the papers arose almost immediately, leading to an investigation by RIKEN, the headquarters of the network of the nationally funded laboratories that is based in Wako near Tokyo. Investigators documented several instances of fabrication and falsification in the papers and concluded that some of these constituted research misconduct on the part of [Haruko] Obokata [the lead author].

Japanese media recently reported that authors had agreed to retract the papers but were discussing the wording of the notice. In the note that appeared today, the authors point to errors previously identified by RIKEN investigations in supplementary documents. They also identify additional errors in both papers, including mix-ups in images, mislabeling, faulty descriptions, and “inexplicable discrepancies in genetic background and transgene insertion sites between the donor mice and the reported” STAP cells. [emphasis mine]

The list of errors now documented sound astonishing. In fact, I can’t see how any serious review by any competent specialist in this field could have missed them all, which suggests that for this research at least the peer-review process is mostly a sham. In fact, in the article Nature admits that its

OCO-2 in orbit

Second time’s the charm: A Delta 2 rocket successfully launched the Orbiting Carbon Observatory 2 (OCO-2) into orbit on Wednesday, five years after the first OCO was lost at launch when its Taurus XL rocket fell into the ocean.

The Earth-observing satellite is designed to globally track the amount of carbon dioxide in the atmosphere.

I have to note that if the science of climate change was so “settled,” as President Barack Obama keeps insisting, why did we then spend half a billion dollars on this satellite? Wouldn’t it make more sense to drop the research and focus entirely on saving the planet?

Another lawsuit presses the IRS

A third lawsuit against the IRS, this one by True the Vote, will demand answers at a hearing on July 11 about those lost emails.

This lawsuit is in addition to the Z-Street and the Judicial Watch suits. Thus, we now have three different judges in three different courts pushing back at the IRS coverup, with hearings scheduled for July 10 and July 11.

As I said, things should get very hot for the IRS and the Obama administration come mid-July.

True the Vote sues Mississippi over voter fraud in Republican primary

True the Vote, the organization harassed by the IRS and the Obama administration for investigating fraud at the polls, has sued the Mississippi Secretary of State over alleged voter fraud in last week’s Republican primary.

Though I found some of Cochran’s campaign efforts quite disgusting, I was not offended that blacks came out to vote for him. As long as their vote is legal, that is their right. However, the allegations of fraud that have been swirling around this election suggest that maybe a closer look is warranted.

Hubble to search for Kuiper Belt targets for New Horizons

After completing a preliminary search for potential Kuiper Belt objects which the Pluto probe New Horizons might visit, scientists have decided to use the space telescope for a deeper more complete search.

As a first step, Hubble found two KBOs drifting against the starry background. They may or may not be the ideal target for New Horizons. Nevertheless, the observation is proof of concept that Hubble can go forward with an approved deeper KBO search, covering an area of sky roughly the angular size of the full Moon. The exceedingly challenging observation amounted to finding something no bigger than Manhattan Island, and charcoal black, located 4 billion miles away.

Free paid vacations for House lawmakers

Who says they’re conservatives? The House Ethics committee, run by Republicans, has quietly eliminated the requirement that elected officials list any privately sponsored travel they receive in their annual financial-disclosure forms.

The move, made behind closed doors and without a public announcement by the House Ethics Committee, reverses more than three decades of precedent. Gifts of free travel to lawmakers have appeared on the yearly financial form dating back its creation in the late 1970s, after the Watergate scandal. National Journal uncovered the deleted disclosure requirement when analyzing the most recent batch of yearly filings. “This is such an obvious effort to avoid accountability,” said Melanie Sloan, executive director of the watchdog group Citizens for Responsibility and Ethics in Washington. “There’s no legitimate reason. There’s no good reason for it.”

Once again more evidence that we the voters must replace as many of these crooks, from both parties, as we can.

A streamlined Arianespace to build Ariane 6?

The competition heats up: The merged Airbus/Safran rocket division has surprised the European Space Agency with a proposed new design for Ariane 6.

The Airbus-Safran proposal, if carried to its logical end, would mean a single company building Ariane vehicles, with fewer subcontractors and much less government oversight. It would likely mean the end of the CNES launcher division as industry takes more control of Ariane design and operations.

In other words, the contractors who build the rockets for ESA want more power over that construction. They want less government oversight, and more ownership of the rocket they build.

Sounds like what’s happening in the U.S., doesn’t it? Giving ownership to the rocket builders means they not only have more flexibility and thus can be more efficient, it makes it easier for them to innovate in both construction and sales.

The sad and dishonest state of economic research

A survey of professional academic economists finds that a large percentage are quite willing to cheat or fake data to get the results they want.

From the paper’s abstract:

This study reports the results of a survey of professional, mostly academic economists about their research norms and scientific misbehavior. Behavior such as data fabrication or plagiarism are (almost) unanimously rejected and admitted by less than 4% of participants. Research practices that are often considered “questionable,” e.g., strategic behavior while analyzing results or in the publication process, are rejected by at least 60%. Despite their low justifiability, these behaviors are widespread. Ninety-four percent report having engaged in at least one unaccepted research practice. [emphasis mine]

That less than 4% engage in “data fabrication or plagiarism” might seem low, but it is a terrible statistic. Worse, the other results make me think that the many of the 96% who said they didn’t do this were lying. 40% admit to doing what they agree are “questionable” research practices, while 94% admit to committing “at least one unaccepted research practice.”

In other words, almost none of these academic economists can be trusted in the slightest. As the paper notes, “these behaviors are widespread.”

Hippos in South America?

A wild herd of hippopotamuses that once belonged to a Colombian drug lord are now spreading across the countryside and no one knows what to do with them.

Situated halfway between the city of Medellin and Bogota, the Colombian capital, Hacienda Napoles was the vast ranch owned by the drugs baron Pablo Escobar. In the early 1980s, after Escobar had become rich but before he had started the campaign of assassinations and bombings that was to almost tear Colombia apart, he built himself a zoo.

He smuggled in elephants, giraffes and other exotic animals, among them four hippos – three females and one male. And with a typically grand gesture, he allowed the public to wander freely around the zoo. Buses filled with schoolchildren passed under a replica of the propeller plane that carried Escobar’s first US-bound shipments of cocaine. While Don Pablo masterminded the operations of the Medellin Cartel from his villa on the hill, the locals gazed at the strange animals and even stranger concrete dinosaurs that Escobar built for his son.

When Hacienda Napoles was confiscated in the early 1990s, Escobar’s menagerie was dispersed to zoos around the country. But not the hippos. For about two decades, they have wallowed in their soupy lake, watching the 20sq km (8 sq mile) park around them become neglected and overgrown – and then transformed back into a zoo and theme park, complete with water slides. All the while, the hippos themselves thrived, and multiplied.

The hippos also escaped from the zoo, and because the environmental conditions in Colombia are ideal for these invasive hippos, they are prospering wherever they go.

Rosetta measures its comet

As Rosetta approaches Comet 67P/Churyumov-Gerisimenko, it has measured the amount of water evaporating of the comet as it slowly comes to life as it approaches the Sun.

ESA’s Rosetta spacecraft has found that comet 67P/Churyumov–Gerasimenko is releasing the equivalent of two small glasses of water into space every second, even at a cold 583 million kilometres from the Sun. The first observations of water vapour streaming from the comet were made by the Microwave Instrument for Rosetta Orbiter, or MIRO, on 6 June, when the spacecraft was about 350 000 kilometres from the comet. Since the initial detection, water vapour has been found every time MIRO has been pointed towards the comet.

That rate of evaporation will increase with time.

Hobby Lobby wins

The Supreme Court today struck down the Obamacare contraceptive mandate imposed by the Obama administration on all businesses.

Despite the opinions of many on the left, some of whom have even threatened to burn Hobby Lobby to the ground for making this challenge, this is a victory for religious liberty. Since when in this country did the government get the right to force religious people of any religion into doing things that directly violate their religious beliefs? This rules clearly says the government does not yet have that right.

No one who supports freedom, however, should rest easy. The decision was 5-4, and with a Democratic Party today quite willing to put restrictions on free speech, we must be prepared for more assaults on freedom.

Another launch success for India

The competition heats up: Using its Polar Satellite Launch Vehicle rocket (PSLV) India successfully launched a French Earth-observation satellite on Monday.

The PSLV continues to be a very reliable commercial rocket for India’s government. That this launch was also witnessed by India’s new prime minister Narendri Modi — who also endorsed his country’s space effort in a public tweet — suggests that India’s space effort has a very bright future.
