An evening pause: Forty-six years ago today Alexei Leonov became the first man to walk in space. This Soviet-era film shows practically the entire event, using footage from two cameras. Unfortunately, I don’t speak Russian and it is not subtitled. I’d love it if someone out there could provide a translation.
Several things to note as you watch:

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.
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.
You can’t make this stuff up! Iran is claiming it has built a working flying saucer.
After an almost seven year journey, Messenger has successfully entered orbit around Mercury. More here.
After years of travel, the probe Messenger finally goes into orbit around Mercury tonight.
Sour grapes: Satellite builders express contempt for MDA’s refueling plans for Intelsat orbiting satellites.
No surprise here. If Intelsat can extend the life of its satellites, than it won’t have to buy them as often from these builders, something the builders clearly don’t want.

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.
Intelsat signs MDA to perform in-space refueling of its communications satellites.
The concept of refueling geosynchronous satellites has been lurking about the aerospace industry for years. According to this deal, we should see an actual mission in about five years.
Problems going up and going down: Not only are there issues with the Soyuz capsule that is scheduled to return to Earth on Wednesday, a problem in the communications system of the next Soyuz capsule has caused the Russians to delay its launch by at least one week.
The return of a crew from ISS on Wednesday via a new upgraded Soyuz capsule might have problems.
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.

More bad news: According to Japanese officials, a second nuclear meltdown is likely under way.
This ain’t good: A nuclear meltdown appears to have occurred at the quake-damaged Japanese power plant.

Putting ISS to use. Key quote:
Under consideration is using the entire station and its six-person crew as an analog for a deep-space human exploration vehicle en route to Mars. An internal team is studying the feasibility and value of such an exercise in the summer of 2012. “We might start with a small window, like a 30-day window, with actual time delays with what we’d expect with a Martian communications system,” Gerstenmaier says. “We may freeze our consumables on station, in the sense of saying that we’ve started our voyage to Mars, and see how well we do in our predictions.”
A Russian military satellite nearly collided with a Korean weather satellite earlier this week.
An evening pause:I had played this video as an evening pause back in November, when I thought the last mission of the space shuttle Discovery would be launched. Now that it has finally landed, completing its final mission, I think worthwhile to once again go back in time and watch a film of the shuttle’s maiden flight, launched August 30, 1984, narrated by the astronauts themselves. Note that the female astronaut on this flight is Judith Resnik, who died a little over a year and a half later in the Challenger accident.
Got a few hundred thousand you can spare? Why not build a doomsday bomb shelter?
