We have a choice
A website, ScienceDebate.org, submitted a wide range of questions to Barack Obama and Mitt Romney about their plans for science and technology, and the answers, shown in a side-by-side comparison, are interesting, though in general they demonstrate the ability of politicians to speak for a long time without saying much.
This ability to blather is especially apparent to their answers to the question 12: “What should America’s space exploration and utilization goals be in the 21st century and what steps should the government take to help achieve them?” Neither candidate adds much to what was said in the Republican and Democratic party platforms, making it obvious that neither really cares or knows that much about this subject.
Overall, however, the answers do reveal the basic and fundamental differences between the two candidates, which can be seen in their answers to the very first question about encouraging innovation:

The Democratic Party platform’s position on space and NASA is one sentence long.
The Democratic Party platform’s [pdf] position on space and NASA is one sentence long.
President Obama has charted a new mission for NASA to lead us to a future that builds on America’s legacy of innovation and exploration.
This is even worse than the Republican Party platform, and is more inexplicable. Considering how much support the Obama administration has given to private commercial space, this was a great opportunity to sell Obama as supportive of private enterprise. Sadly, they do not, which suggests again that Obama and his party really aren’t that interested in it.

Because of the failure to replace a power unit during last week’s spacewalk, the U.S. portion of ISS is now in a brown-out, with a 25% reduction in power.

Sounds great, but Clark Lindsey has a very informative review of the history of these announcements from Russia, none of which has ever born fruit.

Surgery in weightlessness?
Surgery in weightlessness? Two doctors and an engineer are about to test equipment that might make it possible.
The idea actually has more significance for controlling bleeding during brain and spinal surgeries here on Earth.

Though this is a nice write-up describing Sierra Nevada’s Dream Chaser, the part where they talk about using the vehicle like the shuttle to repair other orbiting satellites is a bit of a stretch.

Two astronauts completed an eight hour spacewalk today, extended because of problems with several stuck bolts.
Two astronauts on ISS completed an eight hour spacewalk today, extended because of problems with several stuck bolts.
Williams and Hoshide initially progressed well through their tasks, but the astronauts struggled with difficult bolts when removing a faulty power box from the exterior of the space station, and then again when replacing the defunct unit with a new spare.
More information here. In the end they were forced to leave the replacement unit only temporarily attached because the bolts would simply not screw in. It was thought there might be debris in the screw holes.

At 4:05 am last night the two Radiation Belt Storm Probes (RBSP), designed to study the Van Allen radiation belts, were successfully placed in orbit by an Atlas 5 rocket.
At 4:05 am last night the two Radiation Belt Storm Probes (RBSP), designed to study the Van Allen radiation belts, were successfully placed in orbit by an Atlas 5 rocket.
I am sure these two spacecraft will do good research and find out things about the Van Allen radiation belts that we will need to know when humans start traveling through them routinely. However, I must say that their name, the Radiation Belt Storm Probes, usually abbreviated as RBSP, is probably the worst name NASA has ever devised for a spacecraft: Impossible to remember, boring to hear, and completely forgettable. Other than that, it’s a public relations winner.

More rumors about a year-long mission on ISS
The possibility that NASA might finally agree with Russia’s repeated request to fly a year-long mission to ISS grew stronger this morning with two stories:
- NASA gets set for yearlong stints on space station
- A year on the ISS: Good for tourists – and science
The first, by James Oberg, digs into the underworld of NASA politics to find that plans might very well be more advanced than NASA is letting on:

Russian officials today announced that they will hold additional open cosmonaut recruitment drives, similar to the first held earlier this year, but with revisions.
It appears that the first drive was too short, only six weeks long, and did not get them as many applicants as they would have liked.

Bigelow Aerospace has expanded its workforce as well doubled its factory space in response to the commercial contracts NASA recently awarded.
The competition heats up: Bigelow Aerospace has expanded its workforce as well doubled its factory space in response to the commercial contracts NASA recently awarded.
The company just opened a 185,000-square-foot addition, bringing its North Las Vegas plant up to about 350,000 square feet. It slashed its work force from 150 before the recession to 50 during the downturn; now, it’s looking to jump back up to 90 workers by Christmas. It’s hiring structural, mechanical and electrical engineers, as well as chemists, molecular biologists and workers who craft composite spacecraft parts.

Cave exploration the astronaut way
How not to go cave exploring:
An international crew of six astronauts will start training for a caving adventure designed to prepare them for spaceflight. CAVES, an abbreviation of Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills, prepares astronauts to work safely and effectively and solve problems as a multicultural team while exploring uncharted areas using space procedures.
Or to put it more bluntly, overly complicated, bureaucratically organized, and not very efficient. For example:

One reason why Neil Armstrong got the job
An evening pause: This short clip from the Discovery Science series Rocket Science illustrates one reason Neil Armstrong got the job to land the first spacecraft on the Moon, even though it shows Armstrong crashing his test vehicle!
The man was cool-headed. Not only did Armstrong not panic when a thruster failed, he kept trying to regain control of the craft until the last moment, ejecting less than a second before impact. Then, he was calm about it afterward, hardly mentioning the incident to others.
