Engine problems on a Delta 4 rocket launch two weeks ago could delay the launch of the Atlas 5 rocket scheduled to lift the X-37B on its next mission.

Don’t ask me why the military would delay an Atlas 5 launch because of problems on a Delta 4. It seems to be left over caution from the 1960s, when no rocket was reliable and they were trying to figure out how to do it. Now, it simply seems silly.

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, 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

The first analysis of the water from Lake Vostok, buried deep under the Antarctic icecap, has shown no evidence of life.

The first analysis of the water from Lake Vostok, buried deep under the Antarctic icecap, has shown no evidence of life.

Bulat and his colleagues counted the microbes present in the ice sample and checked their genetic makeup to figure out the phylotypes. They counted fewer than 10 microbes/ml — about the same magnitude they would expect to find in the background in their clean room. And three of the four phylotypes they identified matched contaminants from the drilling oil, with the fourth unknown but also most likely from the lubricant.

The scientists note that this is a preliminary result. Further drilling for new deeper samples will take place in 2013.

Orbital Sciences has delayed the first demo launch of its Cygnus cargo capsule until March 2013 at the earliest.

Orbital Sciences has delayed the first demo launch of its Cygnus cargo capsule until March 2013 at the earliest.

The schedule for Antares itself has not been delayed. Launchpad tests are still scheduled to begin next week, with the first engine test set for early November, and the first launch of Antares set for December.

They don’t explain the reason for the Cygnus delay. I suspect they simply decided to be realistic. It was always unlikely that the first Cygnus launch would follow only a month after the first Antares launch, especially if there are any kinks in that launch.

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. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

“This is the election where black folk sit down and say ‘NO MORE!’ and we stay home.”

“This is the election where black folk sit down and say ‘NO MORE!’ and we stay home.”

Read the whole article. It is detailed, and I think gives an accurate portrayal of the present political attitude of the black community. And this is in Chicago. Blacks might not be ready to vote Republican, but they apparently are finally beginning to realize that the Democrats aren’t their saviors.

The mysterious shiny particles uncovered by Curiosity’s scoop are from Mars, not the rover.

The mysterious shiny particles uncovered by Curiosity’s scoop are from Mars, not the rover.

After last week’s plastic encounter, Curiosity’s science team worried the new particles might be man-made. Since they turned up in scoop holes, however, the granules must have been buried in the subsurface. They likely came from larger minerals that broke down. They might also represent the product of some geological soil process that generates a bright but unknown mineral.

These are not the same mysterious objects first seen when the rover began science operations. Those particles were on the surface, and looked like bits of plastic that might have come off the rover or its descent stage.

A Texas judge is expected to rule today on whether cheerleaders have the right to quote the bible at high school football games.

A Texas judge is expected to rule today on whether cheerleaders have the right to quote the bible at high school football games.

And if he rules they can’t, I say they should go ahead anyway, as they have the right to express themselves no matter what a judge says.

Update: The judge has ruled in favor of the cheerleaders.

Blue Origin has successfully tested its new hydrogen/oxygen rocket engine.

9:27 am

The competition heats up: Blue Origin has successfully tested its new hydrogen/oxygen rocket engine.

This would be the second new American rocket engine since the 1980s, following SpaceX’s Merlin engine. That it uses hydrogen/oxygen is also significant, as these fuels provide the highest ratio of power to weight. (As far as I remember, the shuttle was the only other spacecraft to use hydrogen/oxygen.)

Post corrected. Thanks Paul!

The science team for New Horizons is considering shifting the spacecraft’s Pluto flyby away from the planet to avoid orbital debris.

The science team for New Horizons is considering shifting the spacecraft’s Pluto flyby away from the planet to avoid orbital debris.

“We’ve found more and more moons orbiting near Pluto — the count is now up to five,” Stern said. “And we’ve come to appreciate that those moons, as well as others not yet discovered, act as debris generators populating the Pluto system with shards from collisions between those moons and small Kuiper Belt objects.”

Laura Branigan – Forever Young

6:01 pm

An evening pause: Laura Branigan (1957-2004)

Some are like water some are like the heat
Some are the melody and some are the beat
Sooner or later they all will be gone
Why don’t they stay young?
It’s so hard to get old without a cause
I don’t want to perish like a fading horse
Youth’s like diamonds in the sun
And diamonds are forever
So many adventures couldn’t happen today
So many songs we forgot to play
So many dreams waiting out of the blue
We’ll let them come true

Forever young
I want to be forever young
Do you really want to live forever?
Forever and ever

Kepler reveals our Sun might be more variable than we imagine

5:13 pm

More exoplanet news: The problems of Kepler.

The article outlines the status — both good and bad — of Kepler in its hunt for Earthlike exoplanets.

I have already reported on Kepler’s failed reaction wheel. It no longer has a backup and needs every reaction wheel it has to keep it pointed in so precise a manner. Thus, the loss of one more wheel will shut the telescope down.

However, I had not been aware that the scientists now need more than twice as much time, eight years instead of three, to do their work, because they have discovered that sunlike stars are far more variable than expected. To quote the article,

Astronomers have discovered that the nearest star to the Earth, Alpha Centauri, has an exoplanet only slightly heavier than the Earth.

3:28 pm

Big news: Astronomers have discovered that the nearest star to the Earth, Alpha Centauri, has an exoplanet only slightly heavier than the Earth.

Alpha Centauri is actually a triple star system, with two sunlike stars in a tight orbit around each other and a third star far out orbiting them both. The exoplanet orbits one of the inner stars every 3.2 days.

More details from Nature here.

Faced with stiff competition in the launch market, Europe struggles to come up with a competitive replacement for Ariane 5

Faced with stiff competition in the launch market, Europe struggles to come up with a competitive replacement for Ariane 5

“I strongly believe we have to decide, as quickly as possible, to develop a new-generation launcher to be competitive in the market as it is forecast, and with the competitors,” [ESA Director General Jean-Jacques] Dordain said at the Berlin air show last month, a reference to new launch vehicle developments in India, China and the U.S., where Space Exploration Technologies’ low-cost Falcon 9 is challenging the global launcher market.

While space cadets might argue about launch prices till the cows come home, the actual competitors in the industry know better: SpaceX’s low prices are real and are forcing everyone to find ways to lower costs or lose business.

The Cuban government announced today that it will allow its citizens to freely visit other countries for the first time in over a half century.

8:24 am

The Cuban government announced today that, beginning January 13, 2013, it will allow its citizens to freely visit other countries for the first time in over a half century.

This quiet announcement reminds me of what happened in East Germany in 1991. The government then made a quiet announcement saying it would allow travel outside its country, and within days the Berlin Wall was literally being torn down by its citizens. Shortly thereafter East Germany ceased to exist, absorbed into Germany itself, and the communist bloc fell apart.

Hopefully, we shall see the same thing happen to the Cuban dictatorship.

Just two months after the failure of its second stage during launch, Russia’s Proton rocket successfully put a communications satellite into orbit yesterday.

9:01 am

The competition heats up: Just two months after the failure of its second stage during launch, Russia’s Proton rocket successfully put a communications satellite into orbit yesterday.

This quote, from this Space News article, also implies that there is increasing competitive pressure in the launch industry, which I attribute to the success of SpaceX’s Falcon 9:

Perhaps the most striking element of the launch is that Washington- and Luxembourg-based Intelsat agreed to proceed with it so soon after the August failure of the Proton Breeze-M upper stage. It has been common practice following previous Proton failures that a Russian government mission would be the customer on the return to flight. In this case, Intelsat and its insurance underwriters were sufficiently persuaded that Reston, Va.-based ILS and Proton prime contractor Khrunichev Space Center of Moscow had come to grips with the issue to agree to be the customer for the first flight after the failure.

Scientists have found the source of the water on the Moon and Mercury: the solar wind.

8:48 am

Scientists have found the source of the water on the Moon and Mercury: the solar wind. Key paragraph:

“We found that the ‘water’ component, the hydroxyl, in the lunar regolith is mostly from solar wind implantation of protons, which locally combined with oxygen to form hydroxyls that moved into the interior of glasses by impact melting,” said Zhang, the James R. O’Neil Collegiate Professor of Geological Sciences. “Lunar regolith is everywhere on the lunar surface, and glasses make up about half of lunar regolith. So our work shows that the ‘water’ component, the hydroxyl, is widespread in lunar materials, although not in the form of ice or liquid water that can easily be used in a future manned lunar base.” [emphasis mine]

Though this result would explain the detection of hydrogen on the lunar surface and would also mean that this hydrogen is far less useful for future colonists than previously hoped, it doesn’t eliminate the possibility that there is ice in the permanently shadowed craters near the lunar poles that came from other as yet unknown sources.

It now appears to be illegal to drive around in Dearborn, Michigan displaying Israeli flags on your vehicle.

The tolerance of Islam: It now appears to be illegal to drive around in Dearborn, Michigan displaying Israeli flags on your vehicle.

The [driver] involved was driving in front of the high school as it let out. He was backed up in traffic, a police car immediately behind him. He had Israeli flags on truck. When the students began their assault he rolled down his window asking them to stop. After they pulled him over the police used the rolled down window as a pretext to accuse him of instigating the altercation. While being questioned by the police in front of the high school the [driver] received death threats. The police denied hearing them though the individuals involved were only a few feet away.

The assault also included one high school student throwing a bottle at the car.

Damn, I wish I lived close to Dearborn. I would be organizing a large parade of cars with Israeli flags right this minute.
