Their plan is to drill down 2,600 feet to the lake. With the Russians and British, this makes three teams this year trying to drill into the buried lakes of Antarctica.

Pretend gun control!
Now this is a great idea: Pretend gun control!
What we can do is pass a law banning a bunch of made-up things that sound scary, and many gun control proponents already have great ideas along this line. For instance, I read a column in which Howard Kurtz mentioned a ban on high-magazine clips — we can certainly do without something that nonsensical. And I’ve heard the press before mention armor-piercing hollow points and plastic guns (actually, I think we already banned that made-up weapon in the ’80s). And as long as the NRA and Wayne LaPierre go apoplectic about it (“This ban on sorcerer-enchanted guns is just a slippery slope toward eliminating all witch-hexed weaponry!”), gun control proponents won’t know the difference between this and actual gun control.
Considering the level of ignorance about guns exhibited by every one of the gun control advocates, both politicians and media pundits, I almost think we could get away with this.

How the Bigelow module added to ISS will change the space equation.
How the Bigelow module added to ISS will change the space equation.
Looking a bit further down the road, the potential launch of a Bigelow BEAM module, particularly if it takes place on a SpaceX Falcon 9 booster could be a harbinger of much greater things to come. As Mars visionary Robert Zubrin and many others have observed, the addition of an inflatable module similar to that being considered for the station, to the SpaceX Dragon 2.0 capsule greatly increases the available space and capability of a future Dragon to serve both as a Mars transfer vehicle, and / or surface habitat. Add in the introduction of Falcon Heavy, and the pieces for an alternate vision of far more affordable (and timely) inner system exploration begin to fall into place.
Stewart Money has it exactly right. I have never accepted the claim that Orion was the only spacecraft being built that would be capable of going beyond low earth orbit. Add the right components to any manned vehicle, and you have an interplanetary spaceship.
The trick of course is adding the right components. For both Orion and Dragon, the present assumptions are much too nonchalant about what those components are. For humans to prosper on an interplanetary mission, the vessel requires a lot more than a mere capsule and single module.

David Gregory will not be prosecuted.
The law is for little people: David Gregory will not be prosecuted.
This despite the fact that the D.C. Attorney General even admits that Gregory clearly broke the law.
This travesty more than anything demonstrates how pointless these laws are. Gregory waved a high capacity magazine on camera to illustrate the need to ban such items, even though he was doing so in a place, Washington, D.C., where such magazines were already banned. Not only did Gregory prove the law was stupid, the decision not to prosecute him proves that the law exists merely for political reasons. It is used only when it benefits the powers in control. Gregory is on the side of gun control, so of course he gets a pass. Innocent gun owners and supporters of gun rights who happen to be caught traveling in DC with such a banned item, however, can expect jail time.

The demo mission of robotic refueling of satellites on ISS goes forward this month.
Robot refueling of satellites: The demo mission on ISS goes forward this month.
As much as I celebrate this work, conceived and designed by engineers at the Goddard Space Flight Center (the same people who ran the missions that maintained the Hubble Space Telescope), I worry that nothing will come of it. The demo mission itself is designed to duplicate exactly the refueling of several climate satellites already in orbit whose lifespans are ending merely because they are running out of fuel. If the ISS demo succeeds, the next natural step would be to plan an actual robotic mission to refuel these satellites.
The worrisome part is that NASA rarely follows through on this kind of research. For example, the agency did tests of an ion engine back in the early 1970s, and it wasn’t until the late 1990s before they finally flew a mission using that technology. Worse, the federal budget situation probably means there is no money to fly such a mission.
Hopefully, some private company will take a look at this engineering, which is all in the public domain, and decide to use it for their own purposes.

Elvis Presley – Can’t Help Falling In Love
An evening pause: His live performances of this song are wonderful, but I still prefer the original movie version from Blue Hawaii (1961) for its simplicity. The film work might be uninspiring, but the clarity of the song easily makes up for this.

The largest known spiral galaxy. With images.
Measuring tip-to-tip across its two outsized spiral arms, NGC 6872 spans more than 522,000 light-years, making it more than five times the size of our Milky Way galaxy.
For context, the Milky Way and its two Magellanic Clouds could easily fit inside this galaxy, with lots of room to spare.

Our government’s modern scientific method:
Proving others are wrong is not allowed!
An Interior Department official has been accused of trying to disband a fish research division specifically because its research is politically incorrect.
The research division, the Fisheries Resources Branch, had repeatedly found good evidence that the salmon of the Klamath River in the northwest were not suffering significantly from the presence of the dams on that river, contradicting the accepted wisdom that the dams had to be removed in order for these species to survive. The Interior official, Jason Phillips, along with the Fish and Wildlife Service (FWS), did not like these results, and decided that scientific work that “proved others wrong” was unacceptable and had to be squelched. From the actual complaint [pdf]:

Back when the shuttle program was still alive and NASA astronauts could have applied political pressure to keep it running, some said they should, if only to save their jobs. They did not, and instead toed the party line and supported the shuttle’s retirement even though no replacement was even close to being operational.
How’s that working out for you, guys, eh?
The truth is that there is no justification any longer for the astronaut corp at NASA. They have no vehicle, and any future space vehicle is going to be built and operated by others who will chose their own pilots.

More Apophis news: New data from the Herschel Space Telescope suggests that the asteroid is bigger and less reflective than previous believed.
Instead of 900 feet across, they now estimate it has a diameter of about 1070 feet. And knowing that the asteroid has a lower albedo means that astronomers will be better able to gauge the effect of solar radiation on Apophis’s orbit.

A new National Research Council report honestly admits the possibility that the Sun might be an important factor in climate change.
Pigs fly! A new National Research Council report honestly admits the possibility that the Sun might be an important factor in climate change.
The article, from NASA, itself is a remarkably fair assessment of the field’s state of knowledge (which in truth is quite spotty since we really do not yet understand what is going on with the climate). This, as far as I can remember, is the first time in years, since the early 1990s before the global warming advocates took over the climate field and shut down debate, that an official article from a government organization like NASA has been so open about these issues and not toed the politically correct line that “fossil fuels and carbon dioxide are causing global warming and don’t you dare say anything different!”

Scientists now think it is possible for there to be floating methane ice on the lakes of Titan.
Scientists now think it is possible for there to be floating methane ice on the lakes of Titan.
Up to this point, Cassini scientists assumed that Titan lakes would not have floating ice, because solid methane is denser than liquid methane and would sink. But the new model considers the interaction between the lakes and the atmosphere, resulting in different mixtures of compositions, pockets of nitrogen gas, and changes in temperature. The result, scientists found, is that winter ice will float in Titan’s methane-and-ethane-rich lakes and seas if the temperature is below the freezing point of methane — minus 297 degrees Fahrenheit (90.4 kelvins). The scientists realized all the varieties of ice they considered would float if they were composed of at least 5 percent “air,” which is an average composition for young sea ice on Earth. (“Air” on Titan has significantly more nitrogen than Earth air and almost no oxygen.)
