Space Station Saved By a Toothbrush?

Hugh Pickens writes "Denise Chow reports that two spacewalking astronauts successfully replaced a vital power unit on the International Space Station today, defeating a stubborn bolt that prevented the astronauts from properly installing the power unit on the ISS's backbone-like truss with the help of some improvised tools made of spare parts and a toothbrush. Astronauts Sunita Williams and Akihiko Hoshide started by removing the power box, called a main bus switching unit (MBSU), from where it had been temporarily tied down with a tether, then spent several hours troubleshooting the unit and the two bolts that are designed to secure it in place on the space station's truss. After undoing the bolts, the spacewalkers examined them for possible damage, and used improvised cleaning tools and a pressurized can of nitrogen gas to clean out the metal shavings from the bolt receptacles. 'I see a lot of metal shavings coming out,' Hoshide said as he maneuvered a wire cleaner around one of the bolt holders. Williams and Hoshide then lubricated a spare bolt and manually threaded it into the place where the real bolt was eventually driven, in an effort to ensure that the receptacle was clear of any debris. Then the two applied grease to the sticky bolt as well as extra pressure and plain old jiggling until finally 4½ hours into the spacewalk, Hoshide reported: 'It is locked.' When Hoshide reported that the troublesome bolt was finally locked into place, the flight managers erupted in applause while astronaut Jack Fischer at Mission Control told the astronauts 'that is a little slice of awesome pie.'"

Oh please.

If I can invent a robot that has an asshole, surely some government-funded NASAbot can be invented that has teeth.

Ok, didn't reply to this last night because I didn't want the main topic going off sideways. I only troll useless articles and try to keep the politics in articles with a political bent already. Around an election it seems every thread gets political but I won't contribute to that in a real News for Nerds article like this one.

I mean the Democratic Party in the US. It has become anathma to the ideals of the Revolution and is utterly incompatible with any republican (small r) form of government the Founders would recognize as related. Thus, like Cato the Elder I realize one will eventually destroy the other and I am making it plain that I have a preference. The Democrat Party (they hate that phrasing for some reason, so of course I use it) must be purged from all positions of authority down to the last city council member in San Francisco and the very last college president. Getting there will require a reawakening of political discourse not seen since the guns fell silent in the original Revolutionary War but everybody needs a goal, and that is mine.
