Dragon has undocked from ISS and is on its way back to Earth
Dragon has undocked from ISS and is on its way back to Earth.
And here’s a nice description of the “creepy” cargo it is bringing back.
Update: Dragon has successfully splashed down. More here.

Guess who: “He is incompetent, dishonest and not interested in the actual work of governing.”
Seems an apt and accurate description to me. And the man who wrote it was an Obama voter in 2008.

A spacewalk November 1 will attempt to find and repair a coolant leak that could force a power reduction at the station.
Construction workers in space: A spacewalk November 1 will attempt to find and repair a coolant leak that could force a power reduction at the station.
A slight 1.5-pound-per-year leak in the channel 2B cooling system has been present since 2007 and during a shuttle visit last year, two spacewalking astronauts added eight pounds of ammonia to the reservoir to boost it back up to a full 55 pounds. The plan at that time was to top off the system every four years or so to “feed the leak,” replacing the lost ammonia as required.
But over the past few months, engineers saw the leak rate suddenly quadruple, either because something changed at the original leak site or, more likely, because another leak developed somewhere else in the system.
Whether the leakage was caused by space debris or a component failure of some sort is not yet known. But the result is: If the leak continues at its current rate, the coolant will drop below a 40-pound safety limit and the system will shut down by the end of the year or shortly thereafter, taking power channel 2B down with it. While the space station can operate without the full complement of power channels, the loss of channel 2B would force flight controllers to power down equipment, eliminating redundancy and reducing the amount of research the crews could carry out.

The Air Force has released its investigation into the failure of the August test flight of the X-51a hypersonic scramjet.
As first surmised, the problem was a control fin. Though they haven’t set the date for the next test flight, it appears they do intend to proceed.

That seems about right. This gives them about a year of powered flight tests, all manned but with no paying customers, in order to make sure the system is save for customers.

Reactions to the Italian conviction of seven earthquake scientists
Two reactions today to the Italian conviction of seven earthquake scientists:
- Italy’s top scientists resign their government posts after quake conviction.
- What’s wrong with punishing bad predictions?
In the first, scientists are appalled. In the second someone asks what I think is at least a reasonable question. Even if we agree that prison is an overreaction in this case, it does seem valid to me that scientists face some consequences for misstating risks in certain circumstances.
