Five myths about China’s space effort

9:04 am

Five myths about China’s space effort. Key recommendation:

Recognize the significance of space as a field of competition. Beijing is not engaged in a space race with Washington. But China is engaged in a great power competition with the U.S. in which space is one arena. American decision makers should come to terms with this duality. In this regard, the Chinese are unlikely to be manipulated by American proposals on “codes of conduct” or meetings with the head of NASA. As long as Beijing and Washington are in competition, space will be one of the major venues.

And competition is not a bad thing. It is going to be the fuel that gets the human race into space.

Obama administration considering eliminating the ATF

7:51 am

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.

Mars atmosphere has more water vapor than predicted

6:46 pm

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

5:52 pm

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.

Reality always wins

12:19 pm

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

6:35 pm

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

6:19 pm

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.

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.
