All systems are go for a close encounter with one of the smallest yet most active comets known. And it will be happening coincident with Dr. James L. Green's presentation. He is director of the Planetary Science Division at NASA Headquarters in Washington D.C. NASA's Deep Impact spacecraft is hurtling toward Comet Hartley 2 for a breathtaking 700-kilometer flyby Nov. 4. This will be only the fifth time a spacecraft has flown close enough to a comet to snap pictures of its nucleus. Dr. Green will explain how significant this flyby is. He started his NASA career at Marshall Space Flight Center in Huntsville, Ala. Thereafter he was named to positions of escalating responsibility as he led NASA's National Space Science Data Center, Space Science Data Operations Office, Science Proposal Support Office and, in 2006, assumed his current role.
