NASA is sending a $200 million, Canadian-built robot named Dextre (Special Purpose Dexterous Manipulator) up to the International Space Station to help carryout spacewalk missions too dangerous for humans to attempt. The currently disassembled robot is being flown up on the Space Shuttle Endeavour and will be built up on the Space Station. Once constructed, Dextre will be 10 feet high, 5 feet wide and have two arms comprised of seven joints apiece. [ABC News]
