Home John Hagopian (left) collaborated with instrument scientist Lucy Lim to develop a new instrument that relies on carbon nanotubes to provide the electrons needed to excite minerals contained in an extraterrestrial sample. Larry Hess (right) patterns all the leads and patches where the catalyst for growing nanotubes is deposited.

These images, taken with an electron microscope, show the patterned nanotubes that would operate as electron emitters in a new instrument now being developed for analyzing extraterrestrial samples. The right image is a close-up of one of the bumps. (NASA)
