Virgin Galactic is close to getting its FAA launch license.

According to the company’s CEO, Virgin Galactic is close to getting its FAA launch license.

The CEO also said that they hope to fly their first suborbital flight this summer after several lower altitude powered flights.

At this point I will believe this when I see it. Virgin Galactic has made promises like this repeatedly for the past three years, none of which have come true. The time has come for them to put up, or shut up, or finally tell us the truth.

In testimony to Congress Wednesday, Elon Musk described how allowing SpaceX to compete as a military launch provider would significantly lower costs.

The competition heats up: In testimony to Congress Wednesday, Elon Musk described how allowing SpaceX to compete as a military launch provider would significantly lower costs.

[Senator Richard Shelby (R-Alabama)] said the Air Force EELV contracts require compliance with complex oversight and accounting practices that add costs to the program. As a result, he suggested comparing the cost of a SpaceX Falcon 9 and a ULA Atlas or Delta was comparing apples and oranges.

Musk agreed “there is additional cost for U.S. government missions due to the mission assurance process.” And he said SpaceX’s costs for launching a military mission would be 50 percent higher than for a purely commercial launch. Even so, he said, SpaceX could provide a Falcon 9 rocket for around $90 million as opposed to nearly $400 million for a ULA launcher. “Even when you add the Air Force overhead, there’s still a huge difference,” he said. [emphasis mine]

The only reason that Congress is against eliminating the military launch monopoly given to ULA and allowing SpaceX to compete is because the monopoly feeds a lot of pork to the districts of certain but powerful legislators like Shelby.

ULA and Shelby are losing the argument however. The cost differences are too high, and SpaceX has proven that it can do the job efficiently and effectively. Eventually the monopoly will die, and the sooner the better.

China finally reveals Yutu’s problem: the failure of a control circuit prevents it from storing its solar panels during lunar night.

China finally reveals Yutu’s problem: the failure of a control circuit prevents it from storing its solar panels during lunar night.

A functioning control circuit is required to lower the rovers mast and protect the delicate components and instruments mounted on the mast from directly suffering from the extremely harsh cold of the Moonโ€™s recurring night time periods. โ€œNormal dormancy needs Yutu to fold its mast and solar panels,โ€ said Ye. The high gain communications antenna and the imaging cameras are [also] attached to the mast. They must be folded down into a warmed electronics box to shield them from the damaging effects of the Moonโ€™s nightfall when temperatures plunge dramatically to below minus 180 Celsius, or minus 292 degrees Fahrenheit.

“What happens if Russia refuses to fly U.S. astronauts?”

“What happens if Russia refuses to fly U.S. astronauts?”

The problem: the situation in the Ukraine. If tension between the U.S. and Russia worsens then Russia might suspend carrying American astronauts to and from ISS.

The fault here belongs with Congress and George Bush, who decided in the 2000s to let the shuttle retire before its replacement was ready. In addition we can blame Congress in the 2010s for forcing NASA to spend billions on the unaffordable Space Launch System rather than focus on getting humans into space cheaply and quickly.

A retired NASA manager is suing the Discovery Channel for its false portrayal of his action in connection with the Challenger shuttle accident.

Fake but accurate: A retired NASA manager is suing the Discovery Channel for its false portrayal of him in a movie about the Challenger shuttle accident.

The suit says that in the movie’s crucial scene Lovingood is shown testifying falsely that the odds of a shuttle failure were much higher than other NASA engineers calculated. … “The clear statement and depiction was that Lovingood lied about the probability of total failure being 1 in 100,000 when NASA’s own engineers said it was 1 in 200,” the lawsuit says. “This movie scene never took place in real life at any hearing. (Lovingood) was never asked to give any testimony as depicted and he did not give testimony to the question shown in the movie in this made up scene.”

“It makes it look like (NASA leadership) ignored a highly risky situation” in deciding to launch Challenger that day, Lovingood’s attorney Steven Heninger of Birmingham said Friday. Heninger said the movie was the network’s “first attempt at a scripted program … and they took shortcuts because they were writing for drama.” The testimony in the movie was not in the investigation commission’s records or Feynman’s book “What Do You Care What Other People Think?,” both of which were sources for the film, the suit claims.

Though NASA management did consistently claim the shuttle was safer than it actually was, to falsely portray this specific individual as the person who said those lies when he did not is without doubt slander. I hope he wins big.

This is, by the way, a nice example of typical media arrogance. If you are going to fictionalize real events for dramatic purposes, you don’t use the names of real people and put words in their mouth when you do so. It leaves you very vulnerable legally to exactly this kind of lawsuit. That the Discovery Channel did so is good evidence they think they are above the law and do not have to care if they destroy people’s lives.

Returning the Falcon 9 first stage safely: More details about the next attempt during the next Dragon launch to ISS on March 16.

Returning the Falcon 9 first stage safely: More details about the next attempt during the next Dragon launch to ISS on March 16.

Not only will this test do more engine burns, they will attempt the first deployment of the stage’s landing legs. The article also gives more details about the last launch test, as well as the Grasshopper tests.

An investigation into the dangerous leak of water into a spacesuit during a spacesuit last July has found that NASA engineers had missed an earlier failure of the same suit.

An investigation into the dangerous leak of water into a spacesuit during a spacesuit last July has found that NASA engineers had missed an earlier failure of the same suit.

The leak had first happened in a spacewalk a week earlier, and engineers misdiagnosed the problem. In addition, it appears they didn’t look closely enough at it.

Meanwhile, the investigation has pinpointed the cause of the leak as a clogged filter, but still could not trace what caused that clog.

To save fuel United Airlines is adding additional winglets to the wingtips of their airplanes.

To save fuel United Airlines is adding additional winglets to the wingtips of their airplanes.

The radical re-sculpting of traditional winglets adds a new tip below the upturned one that sharply curve backwards like a scimitar. That further reduces wingtip vortices that drag on the wingtips. Each traditional pair of winglets on the 737 cuts fuel consumption by 3.5% to 4% on flights of more than 1,000 nautical miles. The split scimitar upgradeโ€”which costs $545,000, before discountsโ€“will reduce fuel burn by up to 2% more, says United, which hopes to save up to $60 million a year because of the devices, once its fleet is outfitted.

Very smart. Expect to see these winglets appear on all commercial jets in short order.
