Hello, I thought that they could use RAT not for cleaning the panels but for (lets say) pushing the ground and lifting a little bit the Rover. I understand that the RAT arm has not been designed for this but they don't have to lose anything if they try except damaging the tool. Checking a couple of Lab fotos I couldn't see the RAT arm and tool attached to the test rover. If I am right they might not be able to test this option. Christos/Greece
I really wonder if the Rock Abrasion Tool (RAT) arm (the grinder arm) is strong enough to help Spirit move away from its sand trap... Christos/Greece
areYouAHypnotist writes to tell us the New York Times has the scoop on a new comic book about the quest for logical certainty in mathematics. "The story spans the decades from the late 19th century to World War II, a period when the nature of mathematical truth was being furiously debated. The stellar cast, headed up by Bertrand Russell, includes the greatest philosophers, logicians and mathematicians of the era, along with sundry wives and mistresses, plus a couple of homicidal maniacs, an apocryphal barber, and Adolf Hitler."
