Before the rock powder is analyzed, some will be used to scour traces of material that may have been deposited onto the hardware while the rover still was on Earth, despite thorough cleaning before launch."We'll take the powder we acquired and swish it around to scrub the internal surfaces of the drill bit assembly," said JPL's Scott McCloskey, drill systems engineer. "Then we'll use the arm to transfer the powder out of the drill into the scoop, which will be our first chance to see the acquired sample."
