The meltdown that wasn’t
Power has been restored at all six Fukushima reactors
Power has been restored at all six Fukushima reactors in Japan.
Overall, the situation appears completely under control, so much so that in a rational world it probably would be possible to put several of these reactors back in operation. The Reuters story above, however, is amusing to read in one sense, as it struggles mightily to make things sound worse than they are.

The real disaster in Japan
The situation at the Japanese nuclear power planets continues to improve. Key quote:
It’s hard to imagine, but it’s now been eight days since the Honshu quake and tsunami, and evidence continues to accumulate that while it was certainly a bad industrial accident, the “doomsday” and “worst case” scenarios just haven’t happened. Every day longer makes those scenarios even less likely — the reactors are cooling, the Japanese are getting them supplied with power, and the fuel rods haven’t burned.
Meanwhile, the scope of the real disaster in Japan is becoming more clearly known: No bodies or survivors found in tsunami-hit Miyagi community.
Kobe fire department rescue team members, who also worked in areas affected by the Great Hanshin Earthquake, have been operating in Minami-Sanrikucho. But they do not have any idea of the whereabouts of the legions of missing people swept away after massive tsunami swallowed up houses. In all, 8,000 town residents remain missing.
What is it with today’s modern American press, that is obsessed about a non-problem at a nuclear power plant, while close-by whole cities have been laid waste, with literally tens of thousands of people killed?
My heart goes out to the Japanese people. Faced with such destruction, they still seem undaunted and unbowed. May they rebuild their country quickly and with courage.
Power reconnected to Japanese reactor site
Power reconnected to Japanese reactor site.
Increasingly, the panic over the Japanese reactor problems appears to have been overblown and childish. Meanwhile, the real disaster continues, with thousands dead and large areas of the Japanese northeast coast devastated by the earthquake and tsunami.

The situation at the Fukushima nuclear power plant continues to stabilize
Here’s some good news: The situation at the Fukushima nuclear power plant continues to stabilize.
The article has a lot to say about the panicky overreaction of much of the press and political class over this incident. For example:
In summary it appears more and more that health consequences from reactor damage will be extremely minimal even for workers at the site. It will now be a surprise if anyone who has not been inside the plant gates this week is affected by the situation at at all – apart from all the people worldwide who have been taking iodide pills or eating salt unnecessarily. There may also be measurable psychological health effects from the global media-driven hysteria surrounding the situation, of course.

Japan raises nuclear alert level
This ain’t good: Japan has raised the nuclear alert level at its stricken nuclear power plants.
Then again, it appears that the dangers remain limited to a relatively small area, within 20 kilometers of the power plant.

Time to stop nuke hysteria
Time to stop the nuke hysteria. Key quote:
It’s not bad enough that thousands of people may be dead from Japan’s earthquake and devastating tsunami. No, the media is instead obsessing over a nuclear reactor that has killed no one and probably never will.

Two Dogs Defy the Wave
Two dogs defy the wave. This is the key quote, however:
Mr. Kikuchi and his daughter said they will come back every day to look after the dogs, but they are not going to bring the dogs to the shelter. “There are lots of people dead and it’s too much to ask to bring the dogs,” said Mr. Kikuchi. “It would be inconsiderate to other people’s sadness.”

First results from the Hayabusa asteroid samples
First results from the Hayabusa asteroid samples.
A preliminary analysis of asteroid samples returned last year by Japan’s Hayabusa probe show evidence the dust grains have a similar composition to stony meteorites that commonly fall to Earth. . . . The initial research also shows the samples inspected so far contain no organic molecules. Scientists also say the analysis confirms the rocks at Itokawa were formed 4.6 billion years ago at the dawn of the solar system.

A detailed explanation of what has happened at the Fukushima nuclear power plant
Check out this detailed engineering explanation of what has happened, is happening, and will happen at the Fukushima nuclear power plant in Japan. Key quote:
The point is that the nuclear fuel has now been cooled down. Because the chain reaction has been stopped a long time ago, there is only very little residual heat being produced now. The large amount of cooling water that has been used is sufficient to take up that heat. Because it is a lot of water, the core does not produce sufficient heat any more to produce any significant pressure. Also, boric acid has been added to the seawater. Boric acid is “liquid control rod”. Whatever decay is still going on, the Boron will capture the neutrons and further speed up the cooling down of the core.

Japan’s IKAROS Solar Sail Mission Extended for a Year
More solar sail news: Japan’s solar sail mission, IKAROS, has been extended for a year. Key quote:
With the extended lease on life, the team will try new navigational tricks, such as varying the sail’s angle toward the sun and changing the craft’s trajectory. Mori called these “risky” maneuvers because they are not sure if the sail will remain fully extended. They intend to model the sail’s behavior and the craft’s response to plan future solar sail missions.

Cracked nozzled was possible cause of Japanese Venus probe failure
Engineers now think that a cracked nozzle caused the Japanese probe Akatsuki to miss Venus.

Ikaros still operating
The Japanese Venus probe Akatsuka might have failed, but its partner, the solar sail Ikaros, continues to function, and remains in contact with its ground controlers, even at a distance of 45 million miles. (The google translation of the daily blog is sometimes spotty (” I will go home 入Rita bath. It will fit your feet smell.”) but still worth reading,)
