The uncertainty of science: New data from the Large Hadron Collider (LHC) does not correspond to the Standard Model of physics, and suggest the possibility that one or two previously unpredicted particles might exist.
Then again, the explanation could be as simple as instrument error. We will have to wait and see.

The competition heats up: In 2016 China plans to launch its next space station, man it for the first time, while also initiating the launch of two new rockets.
The Chinese as yet have not provided any specific launch dates for any of these projects.
The competition heats up: The Russian government has apparently given the go-ahead to the development of a Falcon 9-like modular rocket, original dubbed Soyuz 5 but now called Fenix (Phoenix).
The images at the link show it to be similar in concept to Falcon 9, with its first stage used as a component to produce multiple configurations. With one first stage it would resemble Falcon 9. In its Falcon Heavy configuration it would use three first stages strapped together. Moreover, the article notes that development would begin as expendable, but shift towards re-usability during operation, like Falcon 9. And it does appear that reducing cost is its main driver, since it will involve the development of only one engine and the reuse of it in every stage, like Falcon 9,
If all goes as outlined in the plan (don’t bet on it), the rocket would be operational by 2025, which is the one difference with Falcon 9. SpaceX got its rocket designed and launched in about five years. The Russian governmental system is going to take ten years to do the same..
The article is a detailed explanation of the rocket mentioned by Deputy Prime Minister Dmitri Rogozin during his confusing television briefing on December 30. The irony here is that, while this rocket might be able to compete with the Falcon 9 of 2016, when it becomes operational in 2025 who knows what will be considered competitive.

A new set of Hillary Clinton emails just released by the State Department includes one in which she is clearly ordering a subordinate to violate the law on how classified material should be transmitted.
Has the State Department released a smoking gun in the Hillary Clinton e-mail scandal? In a thread from June 2011, Hillary exchanges e-mails with Jake Sullivan, then her deputy chief of staff and now her campaign foreign-policy adviser, in which she impatiently waits for a set of talking points. When Sullivan tells her that the source is having trouble with the secure fax, Hillary then orders Sullivan to have the data stripped of its markings and sent through a non-secure channel.
Her exact written words are the title of this post.
More here. To me, it really doesn’t matter whether Hillary Clinton is ever indicted for what are clear violations of the law in how she handled classified material while she was Secretary of State. What matters is that we, as voters, have clear evidence now that she has contempt for the law, that she willingly and nonchalantly lies about it to the public, and that she is simply not a trustworthy individual. And this story is only one of many others about Hillary Clinton that all demonstrate the same things about her.
The competition cools down? Bigelow Aerospace has laid off somewhere between 30 and 50 employees out of approximately 150 total employees.
In a Jan. 6 statement provided to SpaceNews, Bigelow Aerospace President Robert Bigelow said that the company determined that many areas of the company were “overstaffed” and decided to lay off employees to reduce the company’s expenses. “In December of 2015, we analyzed the amount of staff that we employed throughout all of our departments at Bigelow Aerospace, and discovered that numerous departments were overstaffed,” Bigelow said in the statement. “Regrettably, we had to make the choice that, beginning with the New Year, we need to follow standard business protocols, which sensibly requires an attempt to achieve balance in how much staff is necessary.”
The lay-offs do not necessarily indicate the company is failing, only that it is adjusting its payroll to the specific conditions of the moment. They have completed construction of their inflatable module for ISS and now only await its launch. Time to save money until they win their next contract.
The competition heats up: With its January 17 launch from Vandenberg, SpaceX will attempt to land the first stage on a barge in the Pacific.
This will also be the first attempt from the California launch site. If successful, it will give SpaceX greater flexibility on future first stage recoveries, as some launches won’t have the fuel to get the stage back to land but could bring it down on a barge at sea.
In December four of seven zinnia plants in a greenhouse on ISS became sickly or died because they were receiving too much water and developed mold.
The story doesn’t really tell us much, but this paragraph reveals I think some fundamental management problems in the way NASA is running the station:
ISS commander and NASA astronaut Scott Kelly reported the mold to Mission Control Dec. 22 just as Veggie principal investigator Trent Smith was trying to manage the water problem. In pictures, Smith saw water on the plants a few days before. He told Discovery News he was trying to relay a command from NASA’s station operations team to increase fan speed in Veggie, but the mold developed before the command could be put through. One solution was, on Christmas Eve, to designate Kelly “commander” of Veggie. Kelly now has more autonomy to make changes to Veggie’s conditions if he feels the plants need it.
The scientist noticed a problem but was unable to cut through the communications bureaucracy to talk to the astronauts so that changes could be made quickly. Meanwhile, the astronauts on board ISS had not been given the freedom to make common sense changes themselves. The result is that some of the plants died.
The solution, to give an astronaut more “autonomy”, is one that the Russians learned a long time ago on their Mir space station. It was also a lesson NASA learned even longer ago on Skylab. Moreover, when astronauts are finally flying interplanetary spaceships to the planets with greenhouses just like this, they will have to have that autonomy, no matter what rules NASA establishes. It seems amazing to me that NASA is still learning this lesson now.
One more thought: It is not really a problem that the scientist had trouble reaching the astronauts quickly. In fact, it probably indicates an area of management that NASA is handling well. Communications from the ground up to ISS can be a major problem, as everyone wants to talk to the astronauts and if NASA didn’t control that communications the astronauts would never have time to do anything. Thus, placing limits on that communications makes sense, though once again it also requires that the astronauts be given a great deal of freedom to make their own decisions, as they might not be able to talk to the right experts whenever necessary.
The uncertainty of science: New data of the red giant star Betelgeuse says that the star simply doesn’t have the energy to eject the large amount of gas it routinely blows into space.
“[W]e now have a problem”, says Graham Harper, an astrophysicist at the University of Colorado Boulder. “If you’re going to eject matter you have to put energy in, and we’re not seeing that.” Harper and his colleagues used the US–German Stratospheric Observatory for Infrared Astronomy (SOFIA), a 2.5-metre telescope that flies in a modified Boeing 747 aeroplane, to take Betelgeuse’s temperature. They found that the star’s upper atmosphere was much cooler than expected — so cool, in fact, that it doesn’t seem to have enough energy to kick gas out of its gravitational pull and into space.
“This challenges all our theoretical models,” Harper said on 7 January at a meeting of the American Astronomical Society in Kissimmee, Florida. [emphasis mine]
The data suggests the temperature of the ejected gas to be only about 512 degrees Fahrenheit. This is far too cool to fit any theory for explaining the vast amounts of gas that the star routinely puffs into space. It also suggests, not surprisingly, that scientists do not yet have a enough information to develop a clear understanding of stellar evolution. They have enough information to form rough theories, but there is still much too much they do not know.
With time running out as Comet 67P/C-G moves away from the Sun, the Rosetta engineering team is going to try one more time to contact the lander Philae.
The lander team are going to try another method to trigger a reponse from Philae: on 10 January they will send a command, via Rosetta, to attempt to make Philae’s momentum wheel switch on. “Time is running out, so we want to explore all possibilities,” says Stephan Ulamec, Philae lander manager at DLR. Philae’s momentum wheel ensured that it was stable during its descent from the orbiter on 12 November, 2014.
If the command is successfully received and executed, the hope is that it might shift the lander’s position.”At best, the spacecraft might shake dust from its solar panels and better align itself with the Sun,” explains Philae technical manager Koen Geurts at DLR’s lander control centre.
They also believe that one of the lander’s two transmitters and one of its two receivers are broken, which makes communications difficult at best.
