Stardust Comet Aerogel in UC Berkeley Lab 2
'needles' mounted on micro-manipulators

Andrew Westphal, Christopher Snead and Zack Gainsforth have produced over 100 keystones from the Stardust comet aerogel in UC Berkeley. Above is an image of special "needles" mounted on micro-manipulators controlled by computer to carefully and precisely cut out sections of aerogel that contain cometary samples.
