Formation flying in space, without propellants.

Formation flying in space, without propellants.

Electromagnetic formation flight (EMFF) gets around this propellant problem by turning the satellites in a formation into electromagnets. By using a combination of magnets and reaction wheels, spacecraft in formation can move and change their attitude and even spin without propellant. Satellites can change their polarity to attract or repel one another, turn, or shift their relative positions in any manner that doesn’t require changing the center of gravity for the entire formation.

A prototype is going to be tested inside ISS in the near future.

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.

"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

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.

The Russians have begun a six-hour spacewalk today on ISS to prepare the station for the arrival of a new Russian module.

The Russians have begun a six-hour spacewalk today on ISS to prepare the station for the arrival of a new Russian module.

The article also outlines the continuing investigation into the American spacesuit problem from the last American spacewalk, where an astronaut’s suit began to fill with water from an unknown source. It appears they have pinpointed the most likely cause of the leak, but appear to be having problems recreating the failure.

Update: The Russian spacewalk is over, all tasks completed.

The Obama administration is now insisting that the proper term for climate change is “carbon pollution.”

If it ain’t working then the solution is to change the name! The Obama administration is now insisting that the proper term for climate change is “carbon pollution.”

First it was “global warming.” Then it was “climate change.” Then it was “global climate disruption.” Now, “carbon pollution,” which is the most ridiculous term of all, since all life on the planet is made from carbon. Moreover, all animal life exhales carbon dioxide, which means (assuming the “carbon” in this silly term refers to CO2) we are therefore all polluters. Off with our heads! And the plant life that we all depend on breathes carbon dioxide and could not exist without it.

A GAO audit of NASA’s Orion capsule says the program faces delays and budget overruns.

A report by NASA’s inspector general of the Orion program says it faces delays and budget overruns.

I’m not surprised. The audit [pdf] tried to put a good spin on NASA’s effort to build this capsule, but you can’t make a beauty queen out of a cockroach. Even though I truly believe that the agency has worked hard to try to contain costs and meet its schedule, it is impossible for NASA to succeed at this under the constrains imposed on it by Congress.

And then there is this:

Meanwhile, although [the] report focused on Orion, it also reiterated an oft-repeated point: The money NASA has said it will spend on SLS, Orion and associated ground systems is not enough to stage a mission to any extraterrestrial surface. “Given the time and money necessary to develop landers and associated systems, it is unlikely that NASA would be able to conduct any surface exploration missions until the late 2020s at the earliest,” the report says. “NASA astronauts will be limited to orbital missions using” Orion.

In other words, this very expensive project will not go anywhere for almost two decades. Doesn’t that just warm your heart?

The engineering tests to try to save Kepler have found that the mission is essentially over.

The engineering tests to try to save Kepler have found that the mission is essentially over.

A headline at this New York Times article, “NASA’s Kepler Mended, but May Never Fully Recover” is wrong, as the telescope has not been “mended.” They have found they might be able to do some limited science, at the most. NASA is going to review this possibility, weighing the cost versus the benefit, and decide in the fall.

Ten examples of protest images mocking George Bush that were far more offensive and violent than that harmless rodeo clown whose life is now being destroyed.

Ten examples of protest images mocking George Bush that were far more offensive and violent than that harmless rodeo clown whose life is now being destroyed.

Take a look. Though many conservatives did complain about the violence and inappropriateness of these signs, no one on the right ever demanded that the freedom of these protesters should be squelched. Also, there’s this important detail:

These were not just fringe pieces. Some appeared in art galleries and at major film festivals. Left-wing assassination chic means never having to say you’re sorry.

Of course, having noted these facts and thereby defended the constitutional freedom of a rodeo clown to make fun of a leftwing black politician, I (and Michelle Malkin who wrote the post above) therefore must be racists. It’s the only explanation!

Scientists today published a new model that suggests that Voyager 1 actually entered interstellar space in July of last year.

Ad astra: Scientists today published a new model that suggests that Voyager 1 actually left the solar system and entered interstellar space in July of last year.

In describing on a fine scale how magnetic field lines from the sun and magnetic field lines from interstellar space can connect to each other, they conclude Voyager 1 has been detecting the interstellar magnetic field since July 27, 2012. Their model would mean that the interstellar magnetic field direction is the same as that which originates from our sun.

Other models envision the interstellar magnetic field draped around our solar bubble and predict that the direction of the interstellar magnetic field is different from the solar magnetic field inside. By that interpretation, Voyager 1 would still be inside our solar bubble.

This new model might very well explain the conflicting data received from the spacecraft, some of which said it was out of the solar system and some of which said it was not.

Assuming the first demo berthing of Orbital Sciences’ Cygnus capsule to ISS goes well in September, NASA has now scheduled the subsequent cargo missions of Cygnus and Dragon for December and January respectively.

Russia has concluded its investigation into last month’s Proton launch failure and now says its next launch will be on September 15.

Russia has concluded its investigation into last month’s Proton launch failure and now says its next launch will be on September 15.

While the investigation pinpointed the problem — the installation of sensors upside down — none of the news reports about this investigation have mentioned what any corrective actions the Russians are taking. Meanwhile, at least one unnamed Russian engineer is questioning the schedule and the thoroughness of the investigation.

These warrants are generated without suspicion of a crime and do not specify things to be searched. They remain valid for 45 days, permit multiple entries by code officers, and allow officers to film their inspections, which are later publicly available. The whole neighborhood is able to see the letters on a coffee table and the contents of a medicine cabinet. Inspectors are permitted to look through every aspect of a house, wherever there may be violations of “federal, state, county, or city law, ordinance, rule or regulation relating to the construction, alteration, maintenance, repair, operation, use, condition or occupancy of a premises.” Inspectors may look inside “interior surfaces” of closets and drawers to determine if they are “clean and sanitary.”

And then there’s this suspicious fact:

But David Ahl, a board member of the New York State Coalition of Property Owners and Businesses, alleges that the city is engaging in punitive action meant to chill the exercise of the right to deny consent. Through Freedom of Information Law requests he has discovered that city has filed 50 administrative search warrants since 2003, every single one of which target properties owned and managed by members of his organization.

Why is the Rochester government specifically only getting these broad search warrants against members of this particular organization?

“Liberals have targeted this man for personal destruction to create a climate of fear.”

“Liberals have targeted this man for personal destruction to create a climate of fear.”

It is beyond disgusting the number of recent witch hunts being instigated by the left against individuals who have merely said things they didn’t like. Unfortunately, what’s worse is the willingness of too many Americans to pay no attention, or make believe it isn’t happening, or to make excuses for this totalitarian behavior merely because of partisan favoritism.

Oppression is oppression, and should not be tolerated by anyone, not matter what the politics.

And then there is the media, which has joined in the effort to target the weak and innocent while protecting the powerful who do commit acts of bigotry and hate.

True the Vote has found 173 cases of voter fraud in Florida.

What racists! True the Vote has found 173 cases of voter fraud in Florida.

These are examples where someone has registered and voted in two different states. According to modern Democratic Party dogma, trying to stop such behavior is clearly racist and an attempt to suppress the vote, which is probably why the IRS as well as other federal agencies aggressively harassed True the Vote for several years.

Engineers have identified twelve asteroids that could be captured with today’s technology.

Engineers have identified twelve asteroids that could be captured with today’s technology.

Their number one most easily moved space rock is named 2006 RH120. A single rocket burn in 2021 would be enough to place this roughly 4-meter-wide asteroid into orbit around a Lagrange point by 2026. NASA could then launch people to study this object (which would barely be bigger than the astronauts themselves) and learn about its history.

Comet ISON has come out from behind the Sun, and it looks like it will not produce a grand show for us later this year.

Comet ISON has come out from behind the Sun, and it looks like it will not produce a grand show for us later this year.

There will be a lot of stupid commentary criticizing astronomers for hyping this comet, all unfair. The comet had the strong possibility of being spectacular. Astronomers pointed that out, being as hopeful as everyone to see a bright and beautiful comet grace our night skies for a few months. That this is not turning out to be so is not their fault.

As every Constitutional scholar knows, the First Amendment includes a clause that strictly forbids mockery of the President of the United States, depending on who it is, and which party he belongs to. It’s in one of the penumbras of the Constitution, or maybe it’s an emanation. I always get those two mixed up.

Once again, the thugs of the Democratic Party are working to destroy someone, merely because that person happened to express a negative opinion about their Democratic president.
