Aerosmith – Livin’ On The Edge
An evening pause: Good music, but this video reveals a great deal about the future in how it portrays an adolescent view of the present. Even more important, the view is very typical of modern culture.
Another American expresses his anger
The rage builds: “So I’d like to ask the Fed, is it that you just hate the working class here in America and thus like to torment them or are you truly that stuck up your own asses that you just cannot see the light?”
Read it all. I don’t agree with his perspective entirely, but I do agree that the elite of this country are increasingly ignoring the wishes of the general public, for their own gain and to the detriment of everyone else. If they don’t stop this behavior soon, they are going to find this rage coming back to bite them, and that bite is going to hurt everyone very badly.

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, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also 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

Russia abandons super-rocket designed to compete with SLS
The competition heats up: Russia has decided to abandon an expensive attempt to build an SLS-like super-rocket and will instead focus on incremental development of its smaller but less costly Angara rocket.
Facing significant budgetary pressures, the Russian space agency, Roscosmos, has indefinitely postponed its ambitious effort to develop a super-heavy rocket to rival NASA’s next-generation Space Launch System, SLS. Instead, Russia will focus on radical upgrades of its brand-new but smaller Angara-5 rocket which had its inaugural flight in Dec. 2014, the agency’s Scientific and Technical Council, NTS, decided on Thursday, Mar. 12.
For Russia’s space industry, it appears that these budgetary pressures have been a blessing in disguise. Rather than waste billions on an inefficient rocket for which there is no commercial demand — as NASA is doing with SLS (under orders from a wasteful Congress) — they will instead work on further upgrades of Angara, much like SpaceX has done with its Falcon family of rockets. This will cost far less, is very efficient, and provides them a better chance to compete for commercial launches that can help pay for it all. And best of all, it offers them the least costly path to future interplanetary missions, which means they might actually be able to make those missions happen. To quote the article again:
By switching upper stages of the existing Angara from kerosene to the more potent hydrogen fuel, engineers might be able to boost the rocket’s payload from current 25 tons to 35 tons for missions to the low Earth orbit. According to Roscosmos, Angara-A5V could be used for piloted missions to the vicinity of the Moon and to its surface.
In a sense, the race is now on between Angara-A5V and Falcon Heavy. It shall be quite exciting to watch this competition unfold between big government and private enterprise over the next few decades.

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.

Magnetic field science satellites launched
An Atlas 5 rocket successfully launched four NASA research satellites Thursday night designed to study the behavior of the Earth and Sun’s magnetic fields at high resolution.
The quartet of observatories is being placed into an oblong orbit stretching tens of thousands of miles into the magnetosphere — nearly halfway to the moon at one point. They will fly in pyramid formation, between 6 miles and 250 miles apart, to provide 3-D views of magnetic reconnection on the smallest of scales.
Magnetic reconnection is what happens when magnetic fields like those around Earth and the sun come together, break apart, then come together again, releasing vast energy. This repeated process drives the aurora, as well as solar storms that can disrupt communications and power on Earth. Data from this two-year mission should help scientists better understand so-called space weather.

The neck of Comet 67P/C-G in color
Rosetta’s high resolution camera has taken a color image of Comet 67P/C-G’s narrow neck, the area where the most plume activity has taken place.
When seen with the human eye, comet 67P/Churyumov-Gerasimenko is grey – all over. With its color filters Rosetta’s scientific imaging system OSIRIS, however, can discern tiny differences in reflectivity. To this effect, scientists from the OSIRIS team image the same region on the comet’s surface using different color filters. If, for example, the region appears especially bright in one of these images, it reflects light of this wavelength especially well.
“Even though the color variations on 67P’s surface are minute, they can give us important clues”, says OSIRIS Principal Investigator Holger Sierks from the Max Planck Institute for Solar System Research (MPS) in Germany. In a recent analysis performed by the OSIRIS team, the Hapi region clearly stands out from the rest of the comet: while most parts of 67P display a slightly reddish reflectivity spectrum as is common for cometary nuclei and other primitive bodies, the reflection of red light is somewhat lower in this region.
They as yet do not know exactly why the smooth area at the neck has a very slight blueish tinge, though they suspect it is because of the presence of a higher percentage of frozen water.

Yutu reveals a complex lunar geology
The uncertainty of science: The Chinese lunar rover Yutu has uncovered a much more complicated geology history than previously predicted at its landing site on the moon.
Those data paint a detailed portrait of the Chang’e 3 landing site, which sits just 165 feet (50 m) away from a 1,475-foot-wide (450 m) crater known as C1. C1 was gouged out by a cosmic impact that occurred sometime between 80 million and 27 million years ago, the study authors said.
Yutu studied the ground it rolled over, characterized the craters it cruised past and investigated an oddly coarse-textured rock dubbed Loong, which measures about 13 feet long by 5 feet high (4 by 1.5 m). Overall, the rover’s observations suggest that the composition of its landing site is quite different from that of the places visited by NASA’s Apollo missions and the Soviet Union’s Luna program.
The rover found 9 distinct layers, suggesting numerous and different past events that layered the surface.

Ganymede’s underground salt water ocean
By measuring the interaction of Jupiter and Ganymede’s magnetic fields, scientists have been able to estimate the size of the salt water ocean in Ganymede’s interior.
A team of scientists led by Joachim Saur of the University of Cologne in Germany came up with the idea of using Hubble to learn more about the inside of the moon. “I was always brainstorming how we could use a telescope in other ways,” said Saur. “Is there a way you could use a telescope to look inside a planetary body? Then I thought, the aurorae! Because aurorae are controlled by the magnetic field, if you observe the aurorae in an appropriate way, you learn something about the magnetic field. If you know the magnetic field, then you know something about the moon’s interior.”
If a saltwater ocean were present, Jupiter’s magnetic field would create a secondary magnetic field in the ocean that would counter Jupiter’s field. This “magnetic friction” would suppress the rocking of the aurorae. This ocean fights Jupiter’s magnetic field so strongly that it reduces the rocking of the aurorae to 2 degrees, instead of 6 degrees if the ocean were not present. Scientists estimate the ocean is 60 miles (100 kilometers) thick — 10 times deeper than Earth’s oceans — and is buried under a 95-mile (150-kilometer) crust of mostly ice.
That’s more water than contained in all of Earth’s oceans.

Family flees home due to death threats
Modern American freedom: The parents of one of the Oklahoma fraternity students caught on video making a racist chant have fled their home due to death threats.
As vile as the racist chanting was, it was not threatening anyone with death. Moreover, we have something called the first amendment, which protects all speech, even the vile kind. Threatening the parents of someone who says something you don’t like is hardly standing up for righteous principles.
In related news, Christians at George Washington University in the District of Columbia face punishment because they refuse to participate in gay sensitivity training sessions.
A conservative student group at The George Washington University faces punishment, including the loss of its funding, for refusing to engage in LGBT sensitivity training on campus. The students are now being condemned and attacked on campus by those who claim they’re committing an “act of violence” for standing up for their members’ individual rights and Judeo-Christian values. The Young America’s Foundation chapter at the Washington, D.C.-based academic institute has refused to participate in LGBT sensitivity training recently made as a requirement.
Amanda Robbins, vice president of GW YAF, told The Christian Post that their objection to the training “stems not only from many of our members’ Judeo-Christian values, but also from our organization’s commitment to defending the individual rights of every student on campus. We firmly believe that there should be no such preconditions for any student organization to be able to operate freely on campus,” said Robbins.

Tiny grains from the interior ocean of Enceladus
Using Cassini scientists have detected tiny grains of rock orbiting Saturn that they think were formed on the floor of the interior ocean of Enceladus and then spewed out its vents into space.
They believe that these silicon-rich grains originate on the seafloor of Enceladus, where hydrothermal processes are at work. On the seafloor, hot water at a temperature of at least 90 degrees Celsius dissolves minerals from the moon’s rocky interior. The origin of this energy is not well understood, but likely includes a combination of tidal heating as Enceladus orbits Saturn, radioactive decay in the core and chemical reactions.
As the hot water travels upward, it comes into contact with cooler water, causing the minerals to condense out and form nano-grains of ‘silica’ floating in the water. To avoid growing too large, these silica grains must spend a few months to several years at most rising from the seafloor to the surface of the ocean, before being incorporated into larger ice grains in the vents that connect the ocean to the surface of Enceladus. After being ejected into space via the moon’s geysers, the ice grains erode, liberating the tiny rocky inclusions subsequently detected by Cassini.
Additional data suggest that the interior of Enceladus is very porous, which means that interior ocean might not be one large bubble but a complex liquid-filled cave.

Feel the middle-class rage
While this story is about the testimony of a mother before the Arkansas State Board of Education, objecting to Common Core standards and demanding that they be changed or abandoned, I think its most important take-away is watching the intelligent and thoughtful anger she expresses.
I have included the video of her testimony below the fold. Anyone who thinks the tea party movement is dead needs to watch this video to find out how wrong they are. This woman speaking as a representative of over a thousand parents and teachers, all of whom object to Common Core, the federally-imposed education standards. She also reveals the increasing level of rage and anger that is percolating in the general public over the incompetent and destructive dictates that are being imposed on them by bureaucrats in Washington.
The Republican leadership in the House and Senate might think they were elected to keep the government open, but this woman’s testimony tells me that the mid-term elections were a demand by the public for the Republicans to shut it down.
And they better do it soon, because the rage is continuing to build. If our elected officials don’t respond to it soon the very system of democracy on which our society was built — founded on the principle that government is the servant to the people — is going to become very seriously threatened.
The Milky Way is like ripples in a pond
The uncertainty of science: New survey data of the stars in the Milky Way suggest that the galaxy is not only corrugated with concentric ripples — like you’d see if you dropped a stone in a pond — it is also about 50% larger than previous estimates.
I have watched the size of the Milky Way fluctuate up and down depending on the research for the past forty years. Sometimes it is larger than expected. Sometimes smaller. Without doubt we are getting a better idea of its actual size, but don’t be surprised if the numbers continue to bounce about for decades, even centuries, to come.
The confirmation that the spiral arms are the equivalent of ripples in a pond is also not surprising, as it confirms the intuitive conclusion of anyone who looks at a whirlpool-shaped spiral galaxy: It is a whirlpool spiraling into the gravity well at its center.

Virgin Galactic test flights to resume in 2015?
I’ll believe it when I see it: The executive director of the New Mexico Spaceport Authority, which runs Spaceport America, said Tuesday that she hopes Virgin Galactic will resume test flights of a SpaceShipTwo suborbital ship sometime in 2015, with commercial flights beginning in 2016.
She claimed that work on the new ship is about 80% completed, with construction of another ship also underway.
Forgive me if I have my doubts. Virgin Galactic has spent more than a decade making these promises, with no results.

A new song for space
At a press conference Sarah Brightman yesterday revealed that she is working with Andrew Lloyd Webber to create a new song to sing when she visits the International Space Station later this year.
She also said that she will sing it from the station near the end of her visit. While the reason she gave for this schedule was because she needed time to adjust to weightlessness, I also see this as good marketing, allowing time for a pr build-up to get the largest audience possible.

Two astronauts gear up for one year in space
The final preparations are under way for sending two astronauts, one American and one Russian, to ISS for a full year.
Their launch is scheduled for March 27 in a Soyuz capsule.
One other cool aspect of this long mission: The American astronaut, Scott Kelly, has a twin brother, Mark Kelly, who is also an astronaut, though retired. Mark will be duplicating some of Scott’s in-space activities during the mission. Doctors will also compare how Scott’s body changes in weightlessness over time, in comparison to his brother here on Earth.

More evidence NOAA has tampered with climate data
More global-warming fraud: Scientists have uncovered more tampering by NOAA of its climate temperature data to create the illusion that the climate is warming.
When Dr. Roy Spencer looked up summer temperature data for the U.S. Corn Belt, it showed no warming trend for over a century. But that was before temperatures were “adjusted” by National Oceanic and Atmospheric Administration climate scientists. Now the same data shows a significant warming trend.
Spencer, a climate scientist at the University of Alabama in Huntsville, said that the National Climatic Data Center made large adjustments to past summer temperatures for the U.S. Corn Belt, lowering past temperatures to make them cooler. Adjusting past temperatures downward creates a significant warming trend in the data that didn’t exist before. “I was updating a U.S. Corn Belt summer temperature and precipitation dataset from the NCDC website, and all of a sudden the no-warming-trend-since-1900 turned into a significant warming trend,” Spencer wrote on his blog, adding that NCDC’s “adjustments” made the warming trend for the region increase from just 0.2 degrees Fahrenheit per century to 0.6 degrees per century.
As Spencer notes, correcting the data for errors would normally cause adjustments in both directions. NOAA’s adjustments, however, are always in one direction: from cooler to warmer. This suggests manipulation and fraud, not an effort to improve the data. And that they have consistently refused to explain their adjustments in detail further reinforces this conclusion.

Spencer, a climate scientist at the University of Alabama in Huntsville, said that the National Climatic Data Center made large adjustments to past summer temperatures for the U.S. Corn Belt, lowering past temperatures to make them cooler. Adjusting past temperatures downward creates a significant warming trend in the data that didn’t exist before. “I was updating a U.S. Corn Belt summer temperature and precipitation dataset from the NCDC website, and all of a sudden the no-warming-trend-since-1900 turned into a significant warming trend,” Spencer wrote on his blog, adding that NCDC’s “adjustments” made the warming trend for the region increase from just 0.2 degrees Fahrenheit per century to 0.6 degrees per century.
As Spencer notes, correcting the data for errors would normally cause adjustments in both directions. NOAA’s adjustments, however, are always in one direction: from cooler to warmer. This suggests manipulation and fraud, not an effort to improve the data. And that they have consistently refused to explain their adjustments in detail further reinforces this conclusion.
Aerojet Rocketdyne to cut costs and streamline operations
The competition heats up: In renaming itself from GenCorp to Aerojet Rocketdyne, the company also announced today a four year program to cut costs and reduce its workforce by 10%.
It appears that most of the cuts will come from upper management, which suggests the company has identified fat it needs to get rid of in order to compete effectively in the re-energized aerospace industry.

India’s space budget remains stable
India this year has budgeted $1.2 billion for ISRO, the government agency that runs its space program.
The most astonishing thing I learned from this article however was this tidbit:
The total, presented to the parliament Feb. 28, is roughly level with the 2014-15 budget presented last year. However, ISRO typically spends significantly less money than is allocated in any given budget year — for 2014-15 it spent just 58 billion rupees of the 72 billion rupee allocation — so it seems likely that spending in the coming year will fall short of 73.9 billion rupees. ISRO spokesman Deviprasad Karnik acknowledged the possibility that ISRO’s budget will be reduced before the end of the year. [emphasis mine]
Who ever heard of any government agency in the United States routinely spending less than its budget. The idea is unheard of!
