ESA is revamping how it builds rockets in order to compete with SpaceX.

The competition heats up: ESA is revamping how it builds rockets in order to compete with SpaceX.

ESA officials have been spooked by Space Exploration Technologies Corp. (SpaceX) of Hawthorne, Calif., which has demonstrated its technical prowess with the launch of its Falcon 9 rocket and Dragon cargo vehicle to the international space station. SpaceX officials say one of the keys to its success is that Falcon 9 is built in one factory owned by SpaceX.

Read the whole thing. The way ESA builds the Ariane rocket requires too many participants (what we in the U.S. call pork), raising its cost. ESA is now abandoning that approach to cut costs and thus compete with SpaceX.

Bad training of the astronauts led to the failure of the student experiments recently on ISS.

11:25 pm

Bad training of the ISS astronauts by the company supplying the experiments was the reason the student experiments were never turned on.

“Previous crews were given on the ground review and personal interaction prior to launch,” Manber said. “For this mission, the astronaut received hardware training solely via video while on the space station. Clearly, there was a miscommunication resulting from the video instruction.”

Against the advice of almost every farm organization the USDA is proceeding with regulations that will require farmers to individually tag every chicken and cow.

Racists! Against the advice of almost every farm organization the USDA is proceeding with regulations that will require farmers to individually tag every chicken and cow.

Fidelis Hegngi, a senior staff veterinarian at USDA’s Animal and Plant Health Inspection Service, also has his doubts. “To really truly have something like tagging work on poultry you would need to have something absolute because birds move a lot, if you don’t have something absolute, it’s not going to work. … I don’t think the technology is there yet to really implement the bird ID to be fully, fully functional,” Mr. Hegngi said. Government officials have not said whether they would check animals for identification at traffic stops.

Ms. Bergener has a simple solution to the poultry police: “I’m going to do selective passive resistance,” she said. “I’m not tagging.” …

According to the letter to OMB, the USDA’s disconnect with farmers does not stop at rules for poultry. The USDA estimates a rancher’s cost to identify cattle at 18 cents a head, but the letter cites a study from North Dakota State University that places the actual cost of cow citizenship at $20 a head.

Nowhere is it explained why the USDA is demanding such stringent ID requirements of farmers, other than to make their lives difficult and to increase the petty power of the Washington bureaucracy.

In other words, for the Obama administration it all can be summarized like this: “Voter ID bad! Chicken ID good!”

An new material has claimed the record as the world’s lightest solid.

An new material has claimed the record as the world’s lightest solid.

Developed by a team from the Technical University of Hamburg and Germany’s University of Kiel, the material is composed of 99.99 percent air, along with a three-dimensional network of porous carbon nanotubes that were grown into each other. Aerographite has a density of less than 0.2 milligrams per cubic centimeter, which allows it be compressed by a factor of 1,000, then subsequently spring back to its original state. Despite its extremely low density, it is black and optically-opaque in appearance. By contrast, the density of metallic microlattice sits at 0.9 mg per cubic centimeter.

Another psychologist has resigned amid questions over the validity of his research.

Another psychologist has resigned amid questions over the validity of his research.

This and other recent cases (here, here, here, here, here, here) are more evidence that the peer review process in some fields is badly broken, that the reviewers are too often not doing the reviewing they are supposed to, and in some cases might very well be participating in scientific fraud themselves.

The Sun has emitted a big flare, and a coronal mass ejection from this is expected to hit the Earth on Saturday.

Chicken Little report: The Sun has emitted a big flare, and a coronal mass ejection from this is expected to hit the Earth on Saturday.

There will be some gnashing of teeth about this flare, but in truth, this sentence says it all:

The radiation storm, in progress, ranks “S1” on NOAA space weather scales, which means it poses no serious threat to satellites or astronauts.

At least 80 House Republicans have signed a letter demanding that Speaker John Boehner (R-Ohio) block any further funding of Obamacare.

At least 80 House Republicans have signed a letter demanding that Speaker John Boehner (R-Ohio) block any further funding of Obamacare.

This story illustrates two things. First, the House Republican leadership has been timid about using its power to block the implementation of Obamacare, even though the public clearly wants it blocked. Second, that about a third of the House Republican membership has already signed the letter, with more signatures expected, suggests that the bulk of the Republican Party is not as timid as their leadership. Moreover, I expect the November election to significantly strengthen this fiscally conservative trend.

Thus, it will not surprise me if we see some very radical budget cuts in the next Congress.

The Virginia spaceport at Wallops Island is on schedule to hand control of its launchpad sometime this month so that Orbital Sciences can begin ground tests of its Antares rocket.

The Virginia spaceport at Wallops Island is on schedule later this month to hand control of its launchpad over to Orbital Sciences so it can begin ground tests of its Antares rocket.

The irony of this press release story is that Orbital has actually been running things, as it took over prepping the launchpad last year when the spaceport was unable to handle it.

From Virgin Galactic come two announcements today

8:59 am

The competition heats up: From Virgin Galactic come two announcements today:

The second is really the big news, especially as it appears they already have some customers.

LauncherOne will be a two-stage vehicle capable of carrying up to 500 pounds (225 kilograms) to orbit for prices below $10 million. The rocket will be launched from Virgin Galactic’s proven WhiteKnightTwo, the uniquely capable aircraft also designed to carry SpaceShipTwo aloft to begin her suborbital missions. Thanks to the extreme flexibility of air launch, Virgin Galactic’s customers will enjoy reduced infrastructure costs in addition to the wide range of possible launch locations tailored to individual mission requirements and weather conditions. Branson and other senior executives announced that work has already begun on the vehicle.
