The CSA's Rex rover has a robotic arm that simulates collecting Martian rock and soil samples. It travels at 4cm/sec (1.57inch/sec). On its six aluminum or rubber wheels, the rover can navigate over obstacles up to 15cm (5.9 inches) high and climb slopes of up to 10 degrees. Rex weighs 140kg (308.64 pounds) and measures 152 x 142 x 76cm (59.84 x 55.9 x 29.92 inches). It can carry up to 30kg (66.13 pounds) of science payloads. In 2010, the CSA jointly field tested the rover with NASA at the Flagstaff Meteor Crater in Arizona. (Source: Canadian Space Agency)
These CSA rovers are a long way past "proof of concept." The concept(s) has(have) already been proven by Curiosity. These are correctly named prototypes, but they're not production prototypes, the type ervin007 apparently is thinking of; they're R&D/engineering prototypes, to test different designs and paths to achieving the same goals. CSA joint tests them with NASA, just like they did the Canadarms, and NASA has the means to put these on the moon, on Mars or in space.
Most cyber attacks could be avoided by adopting a list of Critical Security Controls that were created by the Center for Internet Security. That’s the message from Steve Mustard of the Automation Federation.
George Leopold's talk at last week's Design & Manufacturing Minneapolis helped restore astronaut and engineer Gus Grissom's role in the beginnings of NASA, and outlined how Grissom played a pivotal role in winning the Space Race.
