Five ridiculous gun myths promoted by movies
Five ridiculous gun myths promoted by movies. I like this one:
It’s an old joke by now that nobody runs out of bullets in action movies (unless it’s suddenly convenient to the plot, that is). Hollywood shows some restraint with revolvers–usually no more than 10 or 11 shots per six-shot cylinder–but damn, do they go hog-wild with anything that fires full-auto. So much so that that most of us have wound up with an utterly ridiculous concept of how those guns work. They’re seriously depicting these things firing a hundred times more bullets than they can actually hold.

The story suggests that Virgin Galactic will providing the tourist ferry to their orbital hotel, which is puzzling as that company is only building a suborbital spacecraft at this time.

Richard Branson talks to the Wall Street Journal
Richard Branson talks to the Wall Street Journal about space.
Mr. Branson is still radiating enthusiasm. “We’ve got just short of 500 people now signed up to go, which is actually more people than have been up to space in the history of space travel, and we hope to put those up in our first year of operation,” he says, predicting the first commercial flight by “about next Christmas,” although he acknowledges that there have been many delays.

The Fukushima nuclear reactor has reached the state of cold shutdown
Good news: The Fukushima nuclear reactor has reached the state of cold shutdown.
This means that the reactor core has cooled enough that there is no need to recirculate the water to keep the fuel cool. However, because the reactor continues to leak that water recirculation is still necessary, and will be for years.
As is typical of many modern journalists, the article above is also an unstated editorial both hostile to nuclear energy as well as private enterprise, best shown by the article’s concluding paragraph:
Meanwhile, the Japanese public and many of its politicians remained deeply mistrustful of the situation at Fukushima. In this week’s issue of Nature, two members of the Japanese parliament call for nationalization of the Fukushima Plant, to allow scientists and engineers to investigate exactly what happened inside the reactors, and to reassure the public that the decommissioning will be done with their interests at heart. Regardless of whether you agree with the authors, nationalization seems almost inevitable. The lengthy decommissioning process that will follow this cold shutdown, and the enormous cost involved, make it a job for a government, not a corporation. [emphasis mine]
First, he has no idea what the Japanese public thinks of this situation. Second, there is no evidence that the government could do this job better than the company that runs the reactor. Both conclusions are mere opinion, inserted inappropriately in a news article without any supporting proofs.

Rider on the Storm
At approximately 6:00 pm, Lt Col Rankin concluded that his aircraft was unrecoverable and pulled hard on his eject handles. An explosive charge propelled him from the cockpit into the atmosphere with sufficient force to rip his left glove from his hand, scattering his canopy, pilot seat, and other plane-related debris into the sky. Bill Rankin had spent a fair amount of time skydiving in his career—both premeditated and otherwise—but this particular dive would be unlike any that he or any living person had experienced before.
Or since.

Alan Boyle describes the details behind NASA’s decision to go with simpler contracting for future commercial rocket contracts
Alan Boyle describes the details behind NASA’s decision to go with simpler contracting for future commercial rocket contracts.
If you read the article, you’ll notice that the opposition to this decision comes from a Congressman and the GAO. In both cases they cite safety as an issue, as is by some magic giving NASA a lot of bureaucratic approval rights on every design is going to make the rockets or capsules safer. All this will really do is slow things down, increase costs, and possibly increase risks as the companies will no longer have as many resources to focus on design issues. Instead, they will have to spend a fortune pleasing NASA bureaucrats.
And yes, I call them bureaucrats. Any NASA engineer who spends his or her time looking over the shoulder of another engineer — who is doing the real design work — is nothing more than a bureaucrat. Better to quit NASA and get a job with one of these new companies where you can do some real work.

NASA has decided to stick with the same contracting arrangement it used for the COTS contracts
Good news: NASA has decided to stick with essentially the same contracting arrangement it used for the SpaceX and Orbital Sciences cargo deals to ISS in its future commercial crew and cargo contracts.
This suggests that the NASA bureaucracy, which had wanted more control of the new commercial companies by using a more restrictive contract arrangement, has lost. However, we don’t yet have the details on how the new contracts will be administrated, and as always, the devil is in the details.

LightSquared expresses outrage at leaked GPS test report.
It is interesting that they don’t seem to be complaining about the results, which showed that their system interferes badly with GPS. With the facts and the law against them, it appears instead they are now pounding the table.

Rutan, Allen, Musk, Griffin team up to develop an air-launch rocket system to fire hardware and humans into orbit.
Superstars of space: Rutan, Allen, Musk, and Griffin have teamed up to develop an air-launch rocket system to fire hardware and humans into orbit.
Their concept calls for Rutan, a noted aircraft designer, to create a carrier jet with a 385-foot wingspan and six engines to ferry a liquid-fueled, 120-foot-long rocket built by SpaceX and outfitted with five main engines to altitude where the winged booster will be released for launch into orbit.

Southwest orders 208 Boeing 737s valued at $19 billion
Some good news: Southwest Airlines has ordered 208 of Boeing’s 737, a deal valued at $19 billion. Plus this:
Last month, Boeing said Indonesia’s Lion Air committed to pay $21.7 billion for 230 Boeing 737s. Lion Air also has options for 150 more planes, valued at $14 billion, bringing the deal’s total potential value to $35 billion. But the Lion Air deal is not a certainty; it still has to complete the order. Also in November, Emirates Airlines ordered $18 billion worth of 777s.
Maybe Boeing should pump some of those profits into building the CST-100 manned space capsule and thus win more profits in the space tourism industry.

Orbital Sciences has renamed its Taurus II rocket the Antares rocket
Orbital Sciences has renamed its Taurus II rocket the Antares rocket.
To clear up any marketplace confusion and provide clear differentiation between this new launch vehicle and our Taurus XL rocket. Antares is significantly different – it serves the medium-class space launch market and its liquid fuel first stage technology is major departure from previous Orbital space launch vehicles. In addition, a project of this scale and significance deserves its own name like Orbital’s Pegasus®, Taurus® and Minotaur rocket programs that have come before it.
I think they have also realized they needed to distinguish Antares from the Taurus XL rocket’s recent problems, failing twice to put NASA climate satellites into orbit.

LightSquared actually disrupted 75% of the GPS receivers used during government testing
Actually, those tests weren’t so good after all: LightSquared’s broadband system actually disrupted 75% of the GPS receivers used during government testing.
Morrissey also notes these disturbing facts, considering the Obama administration’s strong support for Lightsquared:
- The CEO of LightSquared has been a big Democratic Party contributor.
- Barack Obama was an early investor in LightSquared.
- The Obama administration has put pressure on military officials to change their opposition to Lightsquared.
