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.

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.
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.

Armstrong and the world
In space, science, and technology, there really is very little new news to report today. Instead, almost all the stories are about the passing of Neil Armstrong. On spacetoday.net alone I count almost seventy stories on Armstrong, practically everything posted since yesterday, And that is only a sampling.
This response tells us several things.

Neil Armstrong
I think the gracious statement by Neil Armstrong’s family sums up his life quite well.
We are heartbroken to share the news that Neil Armstrong has passed away following complications resulting from cardiovascular procedures.
Neil was our loving husband, father, grandfather, brother and friend.
Neil Armstrong was also a reluctant American hero who always believed he was just doing his job. He served his Nation proudly, as a navy fighter pilot, test pilot, and astronaut. He also found success back home in his native Ohio in business and academia, and became a community leader in Cincinnati.
He remained an advocate of aviation and exploration throughout his life and never lost his boyhood wonder of these pursuits.
As much as Neil cherished his privacy, he always appreciated the expressions of good will from people around the world and from all walks of life.
While we mourn the loss of a very good man, we also celebrate his remarkable life and hope that it serves as an example to young people around the world to work hard to make their dreams come true, to be willing to explore and push the limits, and to selflessly serve a cause greater than themselves.
For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.

NASA today announced that recent research on ISS into bone loss due to weightlessness has found that proper exercise and diet can stabilize bone loss.
Good news! NASA today announced that recent research on ISS into bone loss due to weightlessness has found that proper exercise and diet can stabilize bone loss.
Past Russian research on Mir had found that exercise and diet could limit the bone loss, but not stop it entirely. The key difference in this recent work seems to be the use of more sophisticated exercise equipment.
If this research holds up, it eliminates one of the most serious obstacles to interplanetary travel.

NASA scientists in a battle with astronomers over who gets to name things on Vesta and Mars.
A rose by any other name: NASA scientists are in a battle with astronomers over who gets to name things on Vesta and Mars.
This is not a new problem. The International Astronomical Union (IAU) has maintained its power over naming everything in space since the 1960s, even though the IAU has sometimes ignored the wishes of the actual discoverers and explorers and given names to things that no one likes. For example, even though the Apollo 8 astronauts wanted to give certain unnamed features on the Moon specific names, the IAU refused to accept their choices, even though those astronauts were the first human beings to reach another world and see these features up close.
Eventually, the spacefarers of the future are going to tell the IAU where to go. And that will begin to happen when those spacefarers simply refuse to use the names the IAU assigns.

What do you do with a giant space station when its lifespan is over?
The article notes that no date has been set for deorbit, and that it likely will not happen before 2028. The article also includes information about some of medical and engineering problems of long term weightlessness that have been discovered on ISS, and how engineers have attempted to address them.
Unfortunately, some of these problems, such as the recently discovered vision problems, remain unsolved. It is a shame that while Russia wants to do multi-year missions on the station to study these issues, NASA continues to resist.

One of Curiosity’s two wind sensors has been found to be damaged and is inoperable.
One of Curiosity’s two wind sensors was apparently damaged in landing and is inoperable.
The Rems team first noticed there was something wrong when readings from the side-facing boom were being returned saturated at high and low values. Further investigation suggested small wires exposed on the sensor circuits were open, probably severed. It is permanent damage. No-one can say for sure how this happened, but engineers are working on the theory that grit thrown on to the rover by the descent crane’s exhaust plume cut the small wires. The wind sensor on the forward-facing mini-boom is unaffected. With just the one sensor, it makes it difficult to fully understand wind behaviour.

Monday’s successful spacewalk by two Russian astronauts has prepared ISS for the arrival of a new Russian module.
I should have posted a link about this spacewalk earlier. What is important however is that the Russians continue to move forward, though slowly. And they continue to come up with simple solutions to problems, such as the extra layer of shielding for the living quarters on ISS, installed during this spacewalk.
