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.

NASA is preparing the next round of commercial contracts to supply cargo to ISS.

The competition heats up: NASA is preparing the next round of commercial contracts to supply cargo to ISS.

NASA announced the plan in a request for information released late Feb. 21. Responses from industry are due March 21. The document, which NASA posted online, did not say when the agency would solicit bids, or when it would make an award for the Commercial Resupply Services 2 (CRS) contract. The expected budget for CRS 2 is between $1 billion and $1.4 billion a year from 2017 to 2024, NASA said. NASA envisions four to five flights a year under CRS 2. Back in January, the White House announced it wanted to extend space station operations through 2024. Congress has currently committed to fund the space station through 2020. CRS 2 contract calls for delivery of 14,250 to 16,750 kilograms per year of pressurized cargo, and delivery of 1,500 to 4,000 kilograms per year of unpressurized cargo.

Assuming both SpaceX and Orbital Sciences win new contracts, this will give them a strong cash flow as they pursue new space endeavors.

A close look at the environmental assessment that Blue Origin submitted to the FAA to get approval for an expanded test operations reveals their intention to do numerous launch abort tests of an orbital crew capsule.

At least, this is how I interpret the paperwork.

The consolidation of the Russian aerospace industry continues as the government considers taking over privately owned Sea Launch.

The consolidation of the Russian aerospace industry continues as the government considers taking over privately owned Sea Launch.

The Russian government will a take closer look at the idea of buying commercial launch services provider Sea Launch, which is owned by a top Russian space contractor but whose key assets are based in California, Russiaโ€™s Deputy Prime Minister Dmitry Rogozin said Feb. 19. Moscow has asked the Russian space agency, Roscosmos, and Russian manufacturer RSC Energia, which holds 95 percent of Swiss-registered Sea Launch, to submit an overview of the financial situation of the maritime launch services company, Rogozin said in remarks posted on the Russian Cabinet website. The Russian government holds 38 percent of Energia, which supplies the upper stage of the Sea Launch rocket.

Should the government go forward with the deal, it likely would move the oceangoing rocket pad and command ship from Long Beach, Calif., to a Russian port on the Pacific Ocean, Rogozin said. โ€œSomething tells me that if we go for it, then the base will definitely be outside the United States,โ€ he said.

Without question the Putin government is trying to recreate the top-down centralized system that existed during the Soviet era, with everything controlled and even owned by the government. While this might please their love of power, I doubt it will be an effiicent way to compete in the open commercial market.

Which means this consolidation is a wonderful opportunity for the new private launch companies. Soon, Russia will be out of the market, focused instead on launching Russian only satellites and spacecraft.
