Obama administration considering eliminating the ATF
Whoa! The Obama administration is considering eliminating the ATF in connection with the guns-to-Mexico scandal.
After a town hall meeting about Operation Fast and Furious in Tucson, Ariz. on Monday, ATF Whistleblower Vince Cefalu, who has been key in exposing details about Operation Fast and Furious, confirmed the elimination of ATF has been circulating as a serious idea for sometime now and that a white paper outlining the plan does exist.
[snip]
[However,] ATF field agents weren’t the problem with Operation Fast and Furious, high ranking officials within ATF and the Department of Justice were and still are. DOJ would eliminate ATF only to take the heat off of the Obama Administration. By eliminating the bureau, it makes it seem like DOJ is taking Operation Fast and Furious so seriously, they decided to “clear out the corruption, clean house,” however, it would only be a distraction away from the people at the top of the investigation. In fact, evidence shows the DOJ has been stonewalling the Oversight Committee investigation into the operation to protect Obama political appointees.
If true, this story suggests that there are many very high level officials in the Obama administration that are very vulnerable to prosecution over Operation Fast and Furious, and they are scrambling to find a way to protect themselves anyway possible.

NASA now claims it can launch a manned mission to lunar orbit by 2019
Forgive me if I remain skeptical: NASA is now claiming it will launch a manned mission to lunar orbit by 2019 using its Space Launch System heavy-lift rocket, the program-formerly-called-Constellation.

Mars atmosphere has more water vapor than predicted
Data from Mars Express has found that the Martian upper atmosphere has far more water vapor than predicted.
“The vertical distribution of water vapour is a key factor in the study of Mars’ hydrological cycle, and the old paradigm that it is mainly controlled by saturation physics now needs to be revised,” said Luca Maltagliati [of the Laboratoire Atmosphères, Milieux, Observations Spatiales (LATMOS) in Guyancourt, France]. “Our finding has major implications for understanding the planet’s global climate and the transport of water from one hemisphere to the other.”
“The data suggest that much more water vapour is being carried high enough in the atmosphere to be affected by photodissociation,” added Franck Montmessin, also from LATMOS, who is the Principal Investigator for SPICAM and a co-author of the paper. “Solar radiation can split the water molecules into oxygen and hydrogen atoms, which can then escape into space. This has implications for the rate at which water has been lost from the planet and for the long-term evolution of the Martian surface and atmosphere.”

Scientists push for monitoring network to collect environmental and socioeconomic data from around the world
What could go wrong? Scientists push for a monitoring network to collect environmental and socioeconomic data from around the world.
Sandy Andelman, an ecologist with Conservation International in Arlington, Virginia, discussed her work setting up a pilot project that began two years ago in southern Tanzania. In addition to basic environmental data about soils, nutrients and land cover, the project tracks agricultural practices. It also incorporates data about income, health and education that is maintained by the government. Andelman says that all the data she collects can be broken down to the level of individual households, and that initial results from the project have already prompted the Tanzanian government to adjust the way it zones agricultural land in the area. [emphasis mine]
Lord help the farmers whose lives will be tracked by this network.

Orbital Sciences restarts engine testing for its Taurus 2 rocket
Orbital Sciences has resumed engine testing for its Taurus 2 rocket.
While many have doubts about SpaceX, SpaceX has at least flown two successful flights of its Falcon 9 rocket. Orbital needs the Taurus 2 to supply ISS, and this rocket remains untested and as yet incomplete, with the schedule bearing down on them.

Reality always wins
Elon Musk’s talk yesterday at the National Press Club revealed several interesting things, about SpaceX’s rocket effort, about the state of the American commercial space industry, and about Elon Musk himself.
First, the company’s rocket design effort. Musk centered his talk on SpaceX’s new effort to make its Falcon 9 rocket completely reusable. Though he produced little specific details, and the moderator at the event asked no questions about it, it seems the engineering centers around these three concepts:

House proposes a budget increase for NIH
The Republican-controlled House has proposed a budget for National Institutes of Health (NIH) that is one billion more than last year’s budget, an increase from $30.7 to $31.7 billion.
What evil budget-cutters these Republicans are! Their mean-spirited budget increase has the nerve to reduce Obama’s budget request by about $120 million, equivalent to a whopping one third of one percent!
This is all shameful. For context, in 2008 NIH’s budget was $29.2 billion. Considering the state of the budget it seems unconscionable for the House to agree to any increase over $30.7 billion. In truth, it is perfectly reasonable to reduce NIH’S budget back to its 2008 number.
Too bad our present Congress, both Democratic and Republican, isn’t reasonable.

NASA has identified ninety percent of the largest near-Earth asteroids
Data from the infrared telescope WISE has now identified ninety percent of the largest near-Earth asteroids.
NASA researchers also downgraded their estimate of the number of medium-sized asteroids, saying there are 44 percent fewer than previously believed. The downside is that scientists have yet to find many of these mid-sized asteroids, which could destroy a metropolitan city.

Rather than follow through on $200 billion of cuts proposed by GAO, the Senate cuts GAO
Don’t you dare tell us to cut spending! Rather than follow through on $200 billion of cuts of “wasteful, duplicative, and fraudulent spending” proposed by General Accountability Office (GAO), the Senate, controlled by the Democrats, has proposed slashing GAO’s budget instead.

SpaceX suspends production of its Falcon 1 rocket
SpaceX suspends production of its Falcon 1 rocket.
As much as I am a fan of Elon Musk and SpaceX, and though I realize that they have been focusing on getting Falcon 9 and Dragon off the ground — the payoff there is greater and a failure of Falcon 1 during this time could be very politically painful — this action contradicts SpaceX’s years of claims that they had a slew of signed contracts to launch Falcon 1.
I will be attending Elon Musk’s luncheon speech today at the National Press Club, and hope to ask him about this and other things.

Exploring an abandoned mine in Nevada
An evening pause: From the youtube webpage:
This inclined shaft is located outside of Searchlight, NV. The shaft itself is about 350 feet deep with two extensive drift levels along its length. We found a winze [a vertical shaft] in the lowest drift level that went down to what appeared to be an additional level.
I must emphasize that mines are very dangerous, and should be approached with great care and caution. Unlike a cave, which has had eons to slowly establish its stable structure, a mine is cut into the rock instantly (compared to geological time), and is thus very unstable and prone to collapse.
Energy Department approves $737 million solar loan guarantee
More money wasted? The Energy Department has approved another solar power company loan guarantee, this for $737 million.
I’m not sure this project will go belly-up, as Solyndra did. I just find it questionable for this to be approved at this moment.

The coming blindness of astronomy
The European Southern Observatory today released this infrared image today of what astronomers have named the Fried Egg Nebula. Taken by the Very Large Telescope in Chile, the picture shows the concentric dust shells surrounding a post-red supergiant star, thought to be transitioning to the next stage of stellar evolution called a yellow hypergiant. As the press release explains,
The monster star, known to astronomers as IRAS 17163-3907, has a diameter about a thousand times bigger than our Sun. At a distance of about 13 000 light-years from Earth, it is the closest yellow hypergiant found to date and new observations show it shines some 500 000 times more brightly than the Sun. . . . If the Fried Egg Nebula were placed in the centre of the Solar System the Earth would lie deep within the star itself and the planet Jupiter would be orbiting just above its surface. The much larger surrounding nebula would engulf all the planets and dwarf planets and even some of the comets that orbit far beyond the orbit of Neptune. The outer shell has a radius of 10 000 times the distance from the Earth to the Sun.
Yellow hypergiants are in an extremely active phase of their evolution, undergoing a series of explosive events — this star has ejected four times the mass of the Sun in just a few hundred years. The material flung out during these bursts has formed the extensive double shell of the nebula, which is made of dust rich in silicates and mixed with gas.
According to the science paper [pdf] describing this research, the stage of yellow hypergiants is a preliminary to the star evolving into a luminous blue variable, of which Eta Carinae is the most famous. In this next stage a star is thought to have a good chance of going supernova.
Though this image is truely spectacular, taken by a ground-based telescope of a star 13,000 light years away, what I find most significant about this image is its fuzziness. It reminds me of the kind of images astronomers and the public routinely accepted as the best possible, before the launch of the Hubble Space Telescope.
