The photograph accompanying the News & Comment article "Jet Propulsion Lab looks to life after Voyager" by M. Mitchell Waldrop (8 Sept., p. 1037) was generated on a VAX with a photoclinometry program developed by Randy Kirk of the U.S. Geological Survey in Flagstaff, Arizona. The Jet Propulsion Laboratory's hypercube computer was not used to generate the panorama shown, as stated in the caption.
