An evening pause: The robot obstacle course at the 2006 ROBO-ONE competition in Kawasaki, Japan. Very impressive, for a machine, though this does illustrate how difficult it is to artificially duplicate what life does so naturally.
A new study has been released detailing the vision problems experienced by astronauts on space flights longer than six months. Hat tip to Clark Lindsey.
The visual system changes discovered by the researchers may represent a set of adaptations to microgravity. The degree and type of response appear to vary among astronauts. Researchers hope to discover whether some astronauts are less affected by microgravity and therefore better-suited for extended space flight, such as a three-year round trip to Mars.
In their report, Drs. Mader and Lee also noted a recent NASA survey of 300 astronauts that found that correctible problems with both near and distance vision were reported by about 23 percent of astronauts on brief missions and by 48 percent of those on extended missions. The survey confirmed that for some astronauts, these vision changes continue for months or years after return to Earth.
With the end of the Mar500 simulated mission this coming Friday, the Russians are now proposing an eighteen month simulated Mars mission on board the International Space Station.
The Russians have been pushing to do this on ISS for years. Unfortunately, NASA has always resisted.
Yet, as I wrote in Leaving Earth, we will never be able to send humans to any other planets until we have flown at least one simulated mission, in zero gravity in Earth orbit, beforehand. Wernher von Braun pointed out this reality out back in the 1950s, and that reality has not changed in the ensuing half century. Not only will such a mission tell us a great deal about the medical issues of living in weightlessness for years at a time — issues that are far from trivial — it will give us the opportunity to find out the engineering problems of building a vessel capable of keeping humans alive during interplanetary flight, far from Earth.

A congressional report today revealed that two American climate satellites were attacked by hackers in the past four years.
In October 2007 and July 2008, a NASA-managed Landsat-7 satellite experienced 12 or more minutes of interference, and a Terra AM-1 satellite was disrupted for two minutes in June 2008 and again that October for nine minutes, according to Bloomberg Businessweek’s analysis of the annual report by the U.S.-China Economic and Security Review Commission. The report says the hackers gained access to the satellites — both are used for Earth climate and terrain monitoring — through the Svalbard Satellite Station in Spitsbergen, Norway. It’s believed the attackers may have hijacked the Internet connection at the Norway ground station to interfere with the operation of the satellites.
Dismantling the last American hydrogen bomb.
The [9 megaton] B53 was designed in the 1950s and replaced 500 B41s, which had a yield of 25 megatons. The largest nuclear device ever built and tested was the 27 ton Russian AN602, which had a yield of 50 megatons. It was eight meters (26 feet) long and 2.1 meters (6.9 feet) in diameter. Only one of these was built. The Russians followed the Americans in phasing out large yield bombs in favor of smaller, and more numerous ones. This was largely the result of ICBM warheads designed to carry multiple nuclear weapons.
A random collection of awesome things. In pictures.
Several Congressmen expressed doubts about and resistance to the new private space manned effort by companies like SpaceX during hearings today in the House.
Let’s be honest: it’s all about pork and only pork. Unfortunately, the new companies don’t deliver the same kind of pork to the right congressional districts, even if they might deliver a real product faster and for less money. To quote the article:
Dana Rohrabacher, R-Calif., rallied to the industry’s defense, citing a “hostility” to the private space industry. “Much to my dismay, I see some of the worst elements of decision making,” he said. “I see an anti-commercial-space attitude that could have very negative consequences.” Rohrabacher (who represents a district near SpaceX’s headquarters) seemed to chide Hall and Johnson, the two Texans who chair the panel, for parochial views. “Focusing on one’s own district and directing federal funds seems to be having a major impact on this decision,” he said.
As we anticipated yesterday, there were other regional pleas connected to the word of choice heard in the halls of Congress: jobs. Rep. Hansen Clarke, D-Mich., for instance, asked how the space contract could be used to create jobs in his district of metropolitan Detroit. The witnesses made the most diplomatic kowtows they could. “I’ve been pushing SpaceX to use more automotive suppliers,” Musk responded. Other space industry execs went on to claim Michigan subcontractors, to praise the auto industry, and to speak of spin-offs from space science programs.

The Vehicle Assembly Building at Cape Canaveral is going to be opened to tourists for the first time in years.
Back in around 1977 I was down in Florida for that year’s science fiction Worldcon convention. At one point we went out to the space center to take the tour. Since this was after Apollo but before the shuttle, the VAB was then part of the tour, and they took us inside at the ground level so we could look up into its vast height. Hopefully, the new tours will let the tourists see more.

Andrew Gasser at the Tea Party in Space website today argues strongly for Congress to fully fund the new commercial space program at the $850 million amount requested by the Obama administration.
As much as I am for these new commercial companies, I do not think it a good idea to fund them at these high levels.
For one thing, the government is still broke. It can’t afford to spend that much money. It is therefore unseemly for a website that uses the “tea party” label to advocate more spending at this time.
For another, the more money the government commits to these companies, the more control the government is going to demand from them. Far better to keep the government participation as small as possible. Make it just enough to allow the companies to succeed but not enough so as to make the whole effort a government program.
NASA is considering putting fuel depots in orbit.
Under the plan outlined in the document, the propellant depot would be launched first, and then other rockets would carry fuel to the depot before a spacecraft arrived to fill up. That would increase the complexity for an asteroid mission — 11 to 17 launchings instead of four — but could get NASA astronauts to an asteroid by 2024, the study said. The total budget needed for the project from 2012 through 2030 would be $60 billion to $86 billion, the study said.
By contrast, a study last year that designed an asteroid mission around a heavy-lift rocket estimated that it would cost $143 billion and that the trip could not happen until 2029. The earlier study briefly considered propellant depots but quickly dismissed them.
This idea of putting fuel depots in space merely mirrors the 1960s proposal of using the Gemini capsule and the Titan rocket to assemble a spaceship in orbit for getting to the moon. According to the earlier proposal it would have been faster and cheaper to use existing smaller rockets and many additional launches than to build a giant Saturn 5 rocket that could put everything into orbit in only one launch. I have always thought this idea had merit.
The fuel depot concept is further confirmation that a heavy-lift rocket is not necessarily the only way one can get humans beyond Earth orbit.
How our government gets Americans in space in the modern era: NASA is negotiating an extension of its deal with the Russians to fly astronauts to ISS.
