Reply 253 that would be consistant with melting Ice but also each time the scoop goes into the trench it will lift that side of Pheonix up as the pressure is exerted to dig in. In addition when a scoop full of soil is manouvered towards the various experiments it will cause a shift in the balance of weight around Pheonix. I wonder if those "ice bits" on the legs fell out of the scoop when moving or depositing into a TEGA or on the Pheonix itself with some overspill landing on the landing gear?
