Canada launches robot-themed plastic banknote from space

By far the coolest thing Canada has in space is Chris Hadfield, commander of the International Space Station. He's all over social and news media with his wacky zero-g demos, guitar playing, and amazing photos of Earth.

Today Hadfield notched another first: unveiling a banknote in space. At a Bank of Canada press conference in Ottawa, the mustachioed colonel appeared via ISS video link. He plucked the bank's latest polymer bill from a bracket on the wall, gave it a few weightless twirls, and pointed to the robots it features.

"I just want to tell you how proud I am to be able to see Canada's achievements in space highlighted on our money," Hadfield told Bank of Canada Governor Mark Carney. "To feature Canadarm2 and Dextre for the theme of the $5 note, it really marks Canada's contribution to the International Space Station Program, and especially our longtime area of expertise in robotics." … Read more

Sorry, San Francisco. An annual Madden NFL Super Bowl simulation predicts the Ravens will trump the 49ers in the final seconds of Sunday's Big Game. Get on this, Vegas! And with "Star Wars" in the news, Crave asks if J.J. Abrams can pull off the impossible directing both "Star Wars Episode VII" and "Star Trek." Are you into it or not into it? Maybe a J.J. Abrams and "Star Wars"-themed musical will help you decide.

Orbiting robot gas station gets closer to reality

It's a bummer running out of gas, especially when the nearest station is 22,000 miles away.

But a project to set up a gas station on the International Space Station made a big leap forward this week with the successful refueling of a mock satellite by a robot.

Dextre, a twin-armed robot from Canada, topped off the fuel tank in the mockup, showing how satellites' life can be extended, according to the Canadian Space Agency (CSA).

Operating on the Robotic Refueling Mission (RRM) module, Dextre removed safety caps and cut through retaining wires before transferring liquid ethanol to the mockup, which is about the size of a washing machine.

The CSA-NASA achievement is the first of its kind, and may help reduce the growing pile of dead satellites and space junk orbiting overhead. … Read more

ISS robot handyman practices with mock satellite

The twin-armed Dextre has managed to retrieve tools and release launch locks on the Robotic Refueling Mission (RRM), an experiment to show that satellites can be refueled by a robot.

Dextre used a wire-cutting tool to sever a wire fastening a mock gas cap to the RRM module, a feat of considerable precision given the fact that Dextre is some 12 feet tall and the wire clearance was only 0.039 inch.

"It's the robotic equivalent of threading a needle while standing on the end of a diving board," the Canadian Space Agency quoted its president, Steve … Read more
