Astronomers have found a solar system with six exoplanets, three in the habitable zone.

8:48 am

Worlds without end: Astronomers have found a solar system with six exoplanets, three in the habitable zone.

These planets orbit the third fainter star of a triple star system. Viewed from one of these newly found planets the two other suns would look like a pair of very bright stars visible in the daytime and at night they would provide as much illumination as the full Moon. The new planets completely fill up the habitable zone of Gliese 667C, as there are no more stable orbits in which a planet could exist at the right distance to it.

The planets in the habitable zone are all super-Earths.

A NASA ion engine has successfully completed more than five and a half years of continuous operation.

A NASA ion engine has successfully completed more than five and a half years of continuous operation.

During the endurance test performed in a high vacuum test chamber at Glenn, the engine consumed about 1,918 pounds (870 kilograms) of xenon propellant, providing an amount of total impulse that would take more than 22,000 (10,000 kilograms) of conventional rocket propellant for comparable applications.

So, now what? Will this engineering achievement be filed away, like so many other past NASA engineering projects, or will it be used for something?

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

Two Russian astronauts completed a six-hour-plus spacewalk today, preparing the station for Russia’s science module.

This science module is many years late, delayed due to Russia’s financial problems after the fall of the Soviet Union. That the Russians are finally about to launch it is another indication, like their recent Proton rocket launch successes, that there space program might be experiencing a resurgence.

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.

Orbital Sciences is scrambling to find a reliable long term first stage engine for its Antares rocket.

Orbital Sciences is scrambling to find a reliable long term first stage engine for its Antares rocket.

The NK-33 engine that powered Antares’ first flight was built decades ago by Russia’s Kuznetsov Design Bureau and is no longer in production. Further, Orbital is uncertain about the quality of Aerojet’s remaining stockpile of 23 NK-33s, beyond those set aside for NASA’s CRS-1. Aerojet Rocketdyne is Orbital’s primary subcontractor and overhauls the old NK-33 engines into a configuration for Antares, dubbed AJ-26. Orbital officials say its only current alternative is the RD-180 engine made in Russia by NPO Energomash. But the United Launch Alliance (ULA), which operates the U.S. Air Force’s Atlas V and Delta IV fleets, holds exclusive rights in the U.S. to buy the RD-180.

Over the last four years, Orbital has inquired about purchasing the RD-180 from ULA, RD Amross and Energomash. “We could never get to first base on that,” says Michael Hamel, the company’s senior vice president of corporate strategy and development. Requests for support from the Air Force, Office of the Secretary of Defense and Congress were also met with silence, company officials say.

What I find disturbing about this story is the complete lack of effort by Orbital, Aerojet, or ULA to build their own engines. Even if new NK-33 engines are made by Aerojet, they will be manufactured in Russia, as are ULA’s engines. Why can’t they do what SpaceX has done and make their own engines?

Europe has successfully drop tested its own experimental re-entry vehicle.

The full-scale Intermediate eXperimental Vehicle (IXV) prototype was released from an altitude of 3000 m by a helicopter, falling to gain speed to mimic a space mission before parachute deployment. The parachute slowed IXV for a safe splashdown in the sea at a speed below 7 m/s. This last step in a series of tests shows that IXV can be recovered safely after its mission into space.

Want to complain about your water quality? You’re a terrorist, according to a Tennessee government official.

Want to complain about your water quality? You’re a terrorist, according to one Tennessee government official.

“We take water quality very seriously. Very, very seriously,” deputy director of TDEC’s Division of Water Resources Sherwin Smith told a baffled and outraged audience in Maury County, Tennessee. “But you need to make sure that when you make water quality complaints you have a basis, because federally, if there’s no water quality issues, that can be considered under Homeland Security an act of terrorism.”

The worst part of this is that this bureaucrat might actually be quoting the law correctly. When Congress created the Department of Homeland Security they created an American version of the KGB, something we don’t need, don’t want, and contradicts every principle this country was founded on.

Scientists have finally discovered the forgotten formula for the concrete the Romans used.

Scientists have finally discovered the forgotten formula for the concrete the Romans used.

The secret to Roman concrete lies in its unique mineral formulation and production technique. As the researchers explain in a press release outlining their findings, “The Romans made concrete by mixing lime and volcanic rock. For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms. The seawater instantly triggered a hot chemical reaction. The lime was hydrated—incorporating water molecules into its structure—and reacted with the ash to cement the whole mixture together.”

The Portland cement formula crucially lacks the lyme and volcanic ash mixture. As a result, it doesn’t bind quite as well when compared with the Roman concrete, researchers found. It is this inferior binding property that explains why structures made of Portland cement tend to weaken and crack after a few decades of use, Jackson says.

Two reports issued today have concluded that implementation of Obamacare by the federal government is behind schedule.

I’m not surprised, considering the opposition to the law combined with its draconian complexity. Even angels — with to cooperation of God and everyone else — would have trouble implementing this mess. Without that cooperation is will be next to impossible.

A 3D printer intended for installation on ISS in 2014 has successfully proven it can work in weightlessness.

A 3D printer intended for installation on ISS in 2014 has successfully proven it can work in weightlessness.

Three prototype versions of space manufacturing startup Made in Space’s 3D printer showed their stuff during four airplane flights that achieved brief periods of microgravity via parabolic maneuvers, company officials announced today (June 19).

Then there’s this:

“The 3D printer we’re developing for the ISS is all about enabling astronauts today to be less dependent on Earth,” Noah Paul-Gin, Made in Space’s microgravity experiment lead, said in a statement. “The version that will arrive on the ISS next year has the capability of building an estimated 30 percent of the spare parts on the station, as well as various objects such as specialty tools and experiment upgrades.” [emphasis mine]

If this claim is true, this printer will do a lot to make interplanetary space travel far more likely. It will mean that travelers far from home will be able to manufacture the spare parts they need, on demand, should something break. This will save a lot of weight, compared to carrying pre-made spare parts.

A professor at a Tennessee college ordered her students to publicly express support for gay rights or fail the course.

4:07 pm

Leftwing debate: A professor at a Tennessee college ordered her students to publicly express support for gay rights or fail her course.

Students in a general psychology class at Columbia State Community College were directed by their professor to wear “Rainbow Coalition” ribbons for an entire day and express their support for the homosexual community, said Travis Barham, an attorney with the Alliance Defending Freedom. …

The professor told students to write a paper about how they were allegedly “discriminated against” because of their support for homosexual conduct. Several students objected to the assignment because their religious convictions prohibit them from supporting conduct their faith teaches them is immoral and unnatural.

Barham said the professor made it clear they had to follow the rules of the assignment to receive credit and allegedly told the students their own beliefs and viewpoints were irrelevant – even when they wrote their papers. The students were also barred from defending or explaining any other views regarding homosexual conduct, dismissing such arguments as “throwing Bible verses” at her,” the attorney said.

A recap of the broken promises of Obamacare.

A recap of the broken promises of Obamacare.

Most of these will be familiar to regular readers of Behind the Black, though the article lays them out very clearly. However, this one is a new one to me:

If your state ran a program to help the uninsured, that’s also a violation, because Insurance is what the ACA is all about. It’s a mandate that you purchase insurance. Any unique solutions generated in one of our 50 incubators must stop even if they have served people well, because they will be in violation of the Affordable Care Act. One of the most successful state Medicaid systems was denied a waiver by the Obama administration despite its proven track record. The worst part of one-size-fits-all solutions is that they are tailored for no one. [emphasis in original]

If you are hoping to buy stock in Elon Musk’s SpaceX company, Musk now says you will have to wait until they have begun regular missions to Mars.

If you are hoping to buy stock in Elon Musk’s SpaceX company, Musk now says you will have to wait until they have begun regular missions to Mars.

This is a change from earlier comments by Musk, which to me suggests that the company’s recent successes and sales has made it profitable enough that he’d rather maintain control than get cash from an IPO. By keeping the company private, Musk can avoid being beholden to stockholders. He can do what he wants.

Russian concerns about a build-up of mold inside the European ATV, now docked to ISS, has caused a delay in the opening of its hatch.

9:35 am

Russian concerns about a build-up of mold inside the European ATV, now docked to ISS, has caused a delay in the opening of its hatch.

The Spaceflight101 portal said the delay was due to possible “mold and bacteria contamination on three cargo bags that are inside the spacecraft” and that a decision is yet to be made on whether the crew should use anti-mold kits to clean ATV-4 cargo before taking it inside the ISS.

The Russians had a lot of problems with mold in their early Salyut space stations, and understand the unpleasant consequences should mold spread into the station. Thus, I am not surprised if they are taking this issue seriously.
