Ground controllers replace a failed circuit box on ISS, using the robot Dextre

6:31 pm

Ground controllers successfully replaced a failed circuit box on ISS this weekend, using the two-armed Dextre robot.

Up to now, exchanging the boxes was done by spacewalkers, which always carries a certain level of risk. Dextre was designed to reduce the need for astronauts to conduct spacewalks for routine maintenance, therefore freeing up the crew’s time for more important activities, like conducting science.

Police confiscate a woman’s legal guns, refuse to return them

6:18 pm

Fire them! Police confiscate a woman’s legal guns, then refuse to return them despite admitting they are legally owned.

Her cache [of weapons] somehow caught the attention of Lakewood Police, who paid a visit last September. When they found Rice wasn’t home, they asked an obliging employee of the complex to open up the apartment without her consent. Once inside, they raided the gun rack, making off with 13 firearms worth around $15,000. The only problem: They had no apparent reason to. [emphasis mine]

Not only did the police essentially steal her property, they entered her apartment illegally.

A preliminary cause for the Russian launch failure has been found

9:19 am

Good news: The Russians have pinned down a preliminary cause for the Progress launch failure last week.

Solving this quickly appears essential, as the space station was not really designed to fly unmanned.

Past NASA risk assessments show there is a one in 10 chance of losing the station within six months if astronauts and cosmonauts are not onboard to deal with any critical systems failures. The probability soars to a frightening one in two chance — a 50-percent probability — if the station is left without a crew for a year.

Power still out

11:43 pm

Update: Power finally returned at about 11:50 pm Sunday.

Power is still out here in DC (as of 11:43 pm Sunday), so my posting must remain light.

Why it takes Pepco so long to restore power to our area, and why this seems to happen ever time there is a storm of any kind, remains a very annoying mystery to me.

Al Gore calls for treating climate skeptics like racists

12:11 pm

Al Gore calls climate skepticism the same as racism and calls for treating skeptics the same.

“There came a time when friends or people you work with or people you were in clubs with — you’re much younger than me so you didn’t have to go through this personally — but there came a time when racist comments would come up in the course of the conversation and in years past they were just natural. Then there came a time when people would say, ‘Hey, man why do you talk that way, I mean that is wrong. I don’t go for that so don’t talk that way around me. I just don’t believe that.’ That happened in millions of conversations and slowly the conversation was won. We have to win the conversation on climate.”

In other words, no expression of skepticism is to be permitted, in any conversation.

I’ll have more to say about this later today or tomorrow.

Archeologists may have found King Arthur’s round table in Scotland

4:13 pm

Archeologists may have found King Arthur’s round table in Scotland.

The new survey — funded by Historic Scotland and Stirling City Heritage Trust — used the latest scientific techniques to showing lost structures and features up to a metre below the ground. It also revealed a series of ditches south of the main mound, as well as remains of buildings, and more recent structures, including modern drains which appear at the northern end of the gardens.

Mr Harrison, who has studied the King’s Knot for 20 years, said: “It is a mystery which the documents cannot solve, but geophysics has given us new insights. “Of course, we cannot say that King Arthur was there, but the feature which surrounds the core of the Knot could explain the stories and beliefs that people held.”

The closest supernovae in almost 25 years

7:56 pm

Astronomers have spotted the closest supernovae in almost 25 years, only 21 million light years away.

The supernova, dubbed PTF 11kly, occurred in the Pinwheel Galaxy, located in the “Big Dipper,” otherwise known as the Ursa Major constellation. It was discovered by the Palomar Transient Factory (PTF) survey, which is designed to observe and uncover astronomical events as they happen. “We caught this supernova very soon after explosion. PTF 11kly is getting brighter by the minute. It’s already 20 times brighter than it was yesterday,” said Peter Nugent, the senior scientist at Berkeley Lab who first spotted the supernova. Nugent is also an adjunct professor of astronomy at UC Berkeley. “Observing PTF 11kly unfold should be a wild ride. It is an instant cosmic classic.”

Astronomers expect the supernova to continue to brighten over the next two weeks, when it should be visible to anyone using binoculars.
